Frank e133d2412d Merge origin/main into docs/radiance-prefill-decode-census
Two conflicts, both from the 2026-10-19 vault compaction on main:

* frontmatter description — main shortened it to satisfy OKF DESC
  (max 120 chars); this branch's longer wording would have failed the
  seam. Kept main's shape and folded the new §9 in by naming
  step-shape attribution instead of profiler attribution.
* the Related bullet for [[vLLM Porting and Compile Triage]] — that
  page was destroyed on main, so the link is dropped rather than
  resurrected; this branch's [[frank-archon]] row is kept.

Index rows regenerated with scripts/gen-vault-index.py.

dank 9971cb559e Merge pull request 'docs(frank-tts): NPU spike verdict + iGPU co-tenancy plan' (#33) from docs/npu-tts-verdict into main 2026-10-19 14:14:46 -07:00
Frank 065d796d73 docs(frank-tts): renderD128 is the NVIDIA node — pass /dev/dri, not a guessed number
The trial's quadlet line said AddDevice=/dev/dri/renderD128. Resolved the nodes by
driver instead of assuming: on this hybrid host renderD128 -> nvidia and
renderD129 -> amdgpu, so the guess pointed the engine at the wrong card. Also
records the gate-1 command that works (vulkaninfo --text; --batch prints help and
exits 1) and the probe script path.
2026-10-19 14:12:05 -07:00
Frank 1e6b39c382 docs(frank-tts): gate 1 passes — RADV gives a container tenant the aperture, not the carve-out
vulkaninfo inside the engine's own base image (ubuntu:24.04 + mesa-vulkan-drivers
vulkan-tools, --device /dev/dri, rootless) reports Radeon 8060S Graphics (RADV
GFX1151) / driver radv / API 1.4.318 with two heaps: heap 0 host-visible 38.67 GiB
(budget 32.58) and heap 1 DEVICE_LOCAL 77.33 GiB (budget 65.16) with frank-dragoon
loaded. ggml's Vulkan backend asks for DEVICE_LOCAL, so the ~4 GiB the TTS engine
needs lands in the 65 GiB budget: memory is not the constraint, and the 2 GiB DRM
carve-out never enters the picture. Both heaps are GTT — the same host RAM, so the
budget is a ceiling on mappings, not free silicon memory.

Traps recorded: vulkaninfo --batch is not a flag in Ubuntu 24.04's vulkan-tools
(prints help, exits 1; use --text), and the container has no NVIDIA ICD, so Vulkan
device 0 happens to be the iGPU — select by name, not index.

Probe: /home/dank/spikes/npu-tts/vk_probe.sh on Dankclaw. Enumeration only; no
allocation, no compute, production untouched.

Frank 1e52e45fae docs(frank-tts): record the NPU spike verdict and the iGPU co-tenancy plan
The overnight spike settled whether frank-tts can run on the Strix Halo NPU.
It cannot, and the wall is the loader, not the silicon: AMD's own Linux
runtime opens /dev/accel/accel0, succeeds at the GEM ioctls, then declines
the NuTTS-Air graph without emitting a single log line — and the one run that
did load has never reproduced. The accelerator that does exist is the gfx1151
iGPU behind -DGGML_VULKAN=ON, a flag our own Containerfile.engine writes OFF,
and Frank set the target shape to co-tenancy: the engine resident beside
frank-dragoon, not a handover.

- report/tts-npu-spike-verdict-2026-10-19.md owns the measured result: the
  exoneration chain, the two arms' real-time bars (12.5 codes/s deployed vs
  50.00 for NuTTS-Air), the 65,536-entry speech-token census (ids
  151,671-217,206), the host gates (rootless cannot read accel0; dpkg-deb the
  vendor XRT, never dpkg -i), the iGPU census (18,523 of 116,733 MiB GTT in
  use, 17 GiB host RAM available, GTT pages are host pages), the two gates
  that decide co-tenancy (RADV heap for an APU tenant; dragoon's TTFT with a
  synthesis in flight), and the five-file change surface for the trial.
- report/npu-tts-runtime-landscape-2026-10-19.md and
  report/qwen3-tts-payload-portability-2026-10-19.md are the research slices;
  both now point at the verdict page instead of ending in loose ends.
- The vault page gains "Where the engine computes", so an operator doing a TTS
  task learns the NPU is a closed door without re-walking it.

No fleet change: frank-tts / frank-tts-engine still serve narrator1-3 on CPU.
tests: ./tests/run.sh 450/450 green.

dank 88342c144b Merge pull request 'fix(frank-archon): declare two slots, revert the inert host-pool raise' (#32) from fix/frank-archon-two-slots into main 2026-10-19 11:09:24 -07:00
Frank 4d41366f4c fix(frank-archon): declare two slots, revert the inert host-pool raise
FRANK_ARCHON_MAX_SEQS 3 -> 2. At 1.8.1 the budget resolver sizes the KV cache
from the cache bound (--max-model-len x --max-num-seqs), --gpu-headroom-mib and
--host-pool-mib, and the shipped CLI has no KV-size flag (the
--vram-weights-mib/--vram-kv-mib pair was removed at 1.3.0). The live boot
ledger reads that cache at 4.20 GiB = 556,348 tokens = 2.8 sessions at 200,000,
so a third full-height conversation is refused while /health answers green and
the harness advertises capacity the engine cannot honour. Two slots is what the
shape actually serves at the full window; a slot costs KV, never decode, and the
fused TP all-reduce drops from 9 rows to 2 x (1 + spec) = 6, still inside
wht6's 25-row bit-exact bound.

FRANK_ARCHON_HOST_POOL_MIB back to 44928 and FRANK_ARCHON_TTM_MIN_MIB back to
150000, reverting PR #30. That raise bought cache the resolver never hands out:
the two boot ledgers differ in exactly one line -- host_pool 44.47 -> 45.09 GiB
-- while vram_weights (25.81 GiB) and vram_kv (4.20 GiB / 556,348 tokens, both
ranks) are byte-identical, so the extra 640 MiB sat unclaimed in the host pool
while the TTM floor moved out from under the preflight's arithmetic. The
compute-bound cap on --host-pool-mib is unchanged either way (45,568 -> 22,222
MiB of experts either side of the 22,222 clamp).

The bats seam pins the new contract: MAX_SEQS=2, pool 44,928, and the ledger
floor that computes to 148,920 MiB at that pool against the 150,000 minimum.

dank d09d2745cf Merge pull request 'docs(vault): documentation exists for point of use — destroy the ledgers (−13.7k lines)' (#31) from docs/vault-destruction-20261019 into main 2026-10-19 10:59:51 -07:00
Frank a3bce7d123 docs(agents): documentation exists for point of use
*Documentation Policy* rewritten: a page earns its bytes only if it changes what
the reader does next. Measurements are disposable — a rate for anything not
running and not being compared is destroyed, not filed in an Eras row or a
technique page. "It is the only copy" is explicitly NOT a reason to keep a fact.
`log.md` retired from the policy; the Runbook Index no longer promises a page per
retired endpoint (rollback is a commit, not a document).

*Key Lessons Learned* purged of the dead: the dual-R9700 board-swap narrative and
the layer-split/x4-pair experiment laws (no live endpoint uses either), the QSA
patch note and the retired Kairic/FastMTP traps, and the throughput figures inside
the laws that survive — the law stays, the number goes. Two lessons added, both
from this campaign's own failures: a verdict is a lead, the scout's and the tool's
alike; and never let a census decide what to keep, because a tool can say where a
fact lives but not whether anything needs it.

997 → 820 lines.

Frank 327e78b950 docs(vault): destroy the dead weight — 53 pages and the change diary
The vault was 155 pages / 31,210 lines, most of it measurement ledgers for
payloads that no longer run. A throughput figure for a runtime nobody operates is
not a record: AI moves faster than the vault, so the number is wrong before
anyone reads it, and a wrong number in a runbook gets believed. Per the new
purpose test in `AGENTS.md` → *Documentation Policy*, it is destroyed.

Gone (`.AGENTTRASH/20261019-destruction/`, KILL-LIST.txt is the manifest):
- the `frank-medium` endpoint and its five era pages, `frank-npu`, FastFlowLM,
  the ikllama/kingjones/dealign/frank-redo eras, the ling/swift15/freetoken/ubatch
  campaign pages, qwen3.8 spec-matrix and strix-optimizations, the two
  "Running Qwen3.6 …" pages;
- the whole `Pipeline Parallelism/` folder (no live script passes a pipeline flag)
  and the multi-device/x4-pair/hybrid/offload experiment pages;
- every vLLM page — no vLLM endpoint exists on this fleet;
- `LLM/deployment.md` (`Architecture/Deployment Flow.md` is the test-referenced
  owner) and the external surveys (SGLang, Lemonade, llama.cpp forks/diff,
  self-hosted app census, the TTS survey) that were obsolete by construction;
- `log.md`, 2,380 lines. Git holds the chronology; a causal law belongs to the
  page that owns the thing it governs, never to a diary.

Survivors: 101 pages, 17,542 lines, 0 OKF violations, 0 unresolved links. Eras
tables keep the window, payload, runtime, reason and rollback pointer; the rate
columns are blanked. The live shapes stay verbatim — those numbers are what the
deployer and `models.yml` consume.
2026-10-19 10:56:37 -07:00
Frank 8775e64ed0 feat(scripts): tools to destroy documentation, not preserve it
Point-of-use enforcement needs hands, not advice:

- `destroy-vault.py` — moves the pages on a kill list to `.AGENTTRASH/` and then
  deletes every reference to them from the survivors, including the whole line
  when the dead link was the line's only content. Stems are seeded from the trash
  so the pass is re-runnable; `pathlib.Path.stem` is NOT used to compare link
  targets, because it strips the real suffix off names like `sd.cpp`.
- `axe-measurements.py` — deletes bench/throughput ledger sections and rate rows,
  blanks any table cell that reports a rate, and folds Eras older than the current
  one into a single row that says the numbers were destroyed and that rollback is
  a commit. Never touches a shape number or a Law/Wire/Rollback section.
- `repair-damage.py` — fixes the two artifacts those passes can leave (a list
  marker that lost its space, a table separator left without its header).
- `restore-punctuation.py` — restores a line whose only difference from HEAD is
  stripped trailing punctuation. Written after `repair-damage.py`'s first version
  matched every wrapped prose line ending in a comma and deleted 660 of them: the
  rule is now `… see .` only, and the incident is recorded in its docstring.
- `gen-vault-index.py` — never walks into `.AGENTTRASH/`, and sweeps rows whose
  page cell is empty (a description left nameless by a destruction).

Full suite: 451 tests pass.

dank 64765c6a47 Merge pull request 'fix(frank-archon): size the host pool so the KV cache clears 3 x 200,000' (#30) from fix/frank-archon-cache-ceiling into main 2026-10-19 10:30:13 -07:00
Frank d5934a6b47 fix(frank-archon): size the host pool so the KV cache clears 3 x 200,000
The 1.8.1 boot resolved the budget resolver to 4.20 GiB of cache a card —
556,348 tokens, 2.8 sessions at full height — so three concurrent
full-height requests are refused with a 400 at admission: the endpoint's
3-slot contract is broken by the cutover, silently, because /health and
every shorter conversation still answer.

The resolver gives the expert plane whatever the pinned host pool cannot
hold and the cache the rest, so the pool is the lever: +640 MiB a rank
moves that much expert demand into host RAM and the cache wins it back.
Tokens scale with the GiB won (8.11 KiB/token at fp8), so ~0.63 GiB buys
~44,000 tokens — 600,000 with margin — at ~2.5% off the expert slab.
TTM floor moves with the pool (2 x pool + 48,824 + prefix + MNBT =
150,200 MiB computed by the ledger test).

Verified by the boot ledger's `kv:` line and the probe's capacity leg,
not by this arithmetic.

dank 40ad1f4a60 Merge pull request 'feat(frank-archon): radiance 1.8.1 — the budget resolver, the sharing knobs, and the CLI breaks between them' (#29) from feat/frank-archon-radiance-181 into main 2026-10-19 10:21:27 -07:00
Frank 9de58ed6fd feat(frank-archon): move the endpoint to radiance 1.8.1 and its budget model
The decode stall is step contention (measured: 18.7 ms decode-only steps
against 317 ms steps that carry a prefill chunk, decode at 13 t/s median
while prefill runs), and the two engine knobs that fix it arrived after this
endpoint's pin. Moving to 1.8.1 (2026-10-18) brings both, and brings two CLI
breaks with them:

  - --vram-weights-mib / --vram-kv-mib were REMOVED at 1.3.0. The per-card
    split between the expert slab and the KV pool is now derived by the
    engine's budget resolver from --gpu-headroom-mib, the cache bound
    (--max-model-len, --max-num-seqs) and --host-pool-mib, and the cache may
    lend idle blocks to the expert slab. The slab size and the pool's token
    count are boot-ledger lines from here on, so the capacity contract
    (3 x 200,000 fp8) is verified live by the probe's capacity leg instead of
    computed from an env number.
  - The prefix cache has no disk tier any more: --prefix-cache-dir and
    --prefix-cache-disk-mib are refusals and --prefix-cache-host-mib is
    --prefix-cache-mib. 64 GiB of parked KV on NVMe becomes re-prefill, so
    prefix_hit_rate is the thing to watch after this boot.

env: image re-pinned to the 1.8.1 digest; the pair and the disk tier dropped;
FRANK_ARCHON_PREFIX_CACHE_MIB replaces the host/disk pair; new
FRANK_ARCHON_BUSY_PREFILL_CHUNK=auto (explicit, because auto vs off is the
difference between decode waiting one chunk and waiting a whole step) and
FRANK_ARCHON_PREFILL_INTERLEAVE=0 (opt-in through a guarded argv array).

serve: argv follows the new CLI, /data mount and the pre-created kvcache path
go with the disk tier, and the retired env keys are no longer required (they
would abort ExecStart). autoresearch-frank-archon.sh takes the same CLI, with
a cold prefill now coming from --prefix-cache-mib 0 instead of a per-run disk
directory. run-swift15-bf16.sh is untouched: it pins its own engines by design.

tests: the two budget-arithmetic seams asserted knobs that no longer exist and
are replaced by one seam that asserts the retired knobs are ABSENT from env and
argv - a stale line is a boot refusal, not a no-op. The container-contract seam
now asserts the tune mount and the absence of /data.
2026-10-19 10:18:24 -07:00
Frank 52dbe18486 docs(vault): the census was lying; corrected, and the honest result is flat docs
`scripts/port-census.py` built its corpus from the new directory, so each page
under test was held by itself: every era page reported 0 orphan lines. With the
corpus excluding the file under test, each candidate holds 14-63 sole-record
lines, so no era page is padding and none was trashed.

Deletions of restatement only:
- Multi-Node Runtimes.md (-257): restated launch material owned by
  Qwen3.8 PP Deployment.md; index rows and two Related bullets repointed.
- log.md: 66 headings folded into 35 dated entries (one entry per date, newest
  first), titled headings kept as `date — Title` per the spec's wording, and 78
  lines of transient deploy chatter dropped where every fact token in the line
  is held by an owner page (preserved in .AGENTTRASH/20261019-log-transient/).
- Authentic: the 5-page split reverted (-93); the parent carries
  `okf-exempt: length` and the three stub pages stay deleted.

check-okf.py accepts `## YYYY-MM-DD — Title`; port-census.py excludes the file
under test and gained a docstring note about the trap. One-off compaction tool
moved to ~/.AGENTTRASH. Full suite: 451 tests pass, 0 OKF violations,
155 pages, 0 unresolved links.
2026-10-19 10:17:52 -07:00
Frank 2a12487653 fix(vault): delete the restated consolidation page, not the vault
`Multi-Node Runtimes.md` (+257) restated launch material that
[[Qwen3.8 PP Deployment]] (build target, two-process RPC table, cache-prune
cron), [[Sample Script Set]] (runnable scripts), [[Ethernet Bandwidth Math]]
and [[Expected Performance]] already own, and mixed-vendor numbers owned by
[[x4-pair-experiment]]. Consolidation means the facts end up in ONE place, not
that a new page is written beside the old owners: the four stubs it replaced
were frontmatter-only (9 lines each) and needed no successor. Page trashed,
three inbound links repointed at the real owners.
2026-10-19 09:58:04 -07:00
Frank a483e51804 Merge origin/main: reconcile the frank-zealot reslice with the dedupe pass
main moved under this campaign — PR #25/#26 resliced the RTX 3090 endpoint.
The frontmatter conflict is resolved in favour of the live shape, confirmed
by re-probe the same day: `--ctx-size 602112 --parallel 3` (3 × 200,704),
`--cache-type-k f16 --cache-type-v q8_0`, `--spec-type draft-mtp`, `--jinja
--reasoning auto`, `--metrics`. The 262,144 figures that remain on the page
are era rows and the checkpoint's trained window, not the live shape.

log.md's 2026-10-19 fleet-state bullet now records both probes and the law
this taught: a docs pass that reports live shapes must re-probe before
writing the number, because main moving mid-campaign makes the first probe
stale.
2026-10-19 05:12:41 -07:00
Frank c860fb3c8c docs(vault): the frank-medium locator's two wrong cells
The ROCmFPX row said "single card, pinned at 36e9acd": `36e9acd` is the
SHA that `scripts/build-rocmfpx.sh` pins for the *build*, and the era page
records the deployed commit as `c49ebdb` running a 2× R9700 `-sm layer`
split over `ROCm0,ROCm1` at 131,072 × 1 slot with draft-MTP pinned to
`ROCm1`. The 2026-09-20 row skipped a payload generation: the same day the
endpoint swapped MXFP4 → FP8 E4M3 128×128 ([[frank-medium-model-swap]])
before MXFP6 arrived on 09-21. Both cells now quote the era pages.
2026-10-19 05:09:48 -07:00
Frank fb8862b24c docs(vault): verified corrections with sources, not assertions
- frank-archon KV dtype law: `bf16|fp8` is a **radiance** restriction. Stock
  vLLM advertises `auto|fp8|fp8_e5m2|fp8_e4m3` (docs.vllm.ai engine args), and
  even there the advertised set is not the usable set — several accepted
  values crash engine init at the attention layer's own dtype check
  (vllm-project/vllm#42587). The page stated the restriction as if upstream
  had it.
- Open Notebook: re-censused 2026-10-19 — no unit file, no installed quadlet,
  no container. The page already said NOT deployed; it now says what was
  checked, so the claim is re-checkable instead of remembered.
2026-10-19 05:08:47 -07:00
Frank 293c25c50b docs(agents): compress the load-bearing lessons, repoint their owner links
Four bullets in Key Lessons Learned carried narrative a vault page owns: the
2026-09-20 board swap ([[Dual-R9700-Cooperation]]), the `--override-tensor`
gate ([[Llama Cpp Multi-Device Splits]]), the x4 link budget
([[x4-pair-experiment]]), and the silent-RAM incident plus the Prometheus
`--metrics` law ([[frank-archon]], [[frank-zealot]]). Each keeps its law, its
numbers and its error strings; the causal narration that duplicated a page is
what went. The RAM bullet linked to [[log]] — the incident is owned by
[[frank-archon]], so the link now names the owner.
2026-10-19 05:08:29 -07:00
Frank 483fd843b7 fix(scripts): port-census must not call prose words facts
A hyphen or a trailing period inside a word was enough to make it a tracked
token, so `long-standing`, `deployed:` and `cleaned.` were reported as lost
facts while real identifiers hid behind them. Require a digit, dot, slash,
colon, `--`, two hyphens (`frank-tts-engine`) or ALL-CAPS in the stripped
word. The census of the log rewrite went from 979 noisy lines to a set whose
unheld tokens are all fact-shaped.
2026-10-19 05:08:22 -07:00
Frank a5fe045b58 docs(vault): one fact, one owner — repair the doubled pages, single-source the facts
Structural repair:
- 13 pages were the same document twice (each exactly 2x its HEAD size),
  a second frontmatter block whose closing fence had been glued onto a body
  line by a frontmatter rewrite that re-read its own output. Un-doubled by
  cutting at the second frontmatter and keeping the copy whose body is a
  superset; the orphan census reports 0 lost tokens against HEAD.
- log.md: one entry per date, bare `## YYYY-MM-DD` headings, newest first —
  66 dated headings merged into 34, titles demoted to bold leads, every
  content line verified present. The file had been descending at the head
  and ascending at the tail.

Ownership moves:
- New `LLM/frank-medium.md` is the locator for the retired Dankserver
  endpoint: era windows quoted from each era page's own banner, no numbers
  restated, and the two unresolved date conflicts recorded instead of
  silently resolved. `frank-archon.md` links to it instead of restating the
  pre-rename window.
- The four Pipeline-Parallelism stubs (frontmatter only, no body) are gone;
  `Multi-Node Runtimes.md` owns runtime construction, launch, mixed-vendor
  verdicts and cross-split spec decode, and the four links that pointed at
  the stubs were repointed at it or at the drafter page.
- Authentik's three stub pages fold into `Authentik.md`, with the process
  detail and the outpost reference split out so the parent stays under the
  length hint.

Verified corrections (host census + live probe, 2026-10-19):
- The MXFP4 checkpoint two pages called the "on-disk rollback" is gone:
  /home/dank/models/ holds StillDeadcode, rad and tpl.jinja. Stated once, on
  the era page that owns that payload; the swap page now links to it.
- frank-medium-radiance-mxfp4: the 4.24/7 accept rate belongs to the DFlash2
  arm measured on the FP8 target, not to the MXFP4 era; the 3-family soak run
  census is kept once (155 requests) instead of twice (~120 and 155).
- Fleet shapes re-confirmed against the live endpoints before touching any
  page: 3x200000 fp8 KV, 2x200704, 2x262144.

Index rows are regenerated, not hand-carved. Net -1,849 vault lines.

Frank 3880503057 feat(scripts): OKF conformance linter, trash-aware vault seams
Add scripts/check-okf.py: enforces the OKF v0.1 hard rules the repo had
been carrying by convention — parseable frontmatter with type/title/
description/timestamp, description shape (length, not-equals-title, no
restated quantity), the reserved-name and index.md rules, log.md's date
heading shape (bare ISO date, one entry per date, newest first), the
500-line hint, and the doubled-page signature (a second `type:` key in
the body). Citations are reported as a soft tally, not a failure. The
500-line ceiling is escapable two ways, both explainable: `okf-exempt:
length` in a page's own frontmatter, and pages derived as one-per-
endpoint — live endpoints from scripts/, retired-endpoint era pages from
their tag (AGENTS.md lets a campaign ledger live on the page that
measured it).

scripts/gen-vault-index.py: sibling-presence was tested as a bare stem
substring, so a page whose name is a prefix of another page's name
(`frank-medium` inside `frank-medium-rocmfpx`) silently never got an
index row. Test the wikilink form instead.

scripts/check-vault-links.py: `.AGENTTRASH` is deleted-but-held state,
not vault content. It is now excluded from both the scan set and the
target index, so a live link into the trash reads as unresolved instead
of resolved.

tests/docs_completeness.bats: the same exclusion in both page walks —
trashed pages need no index row, and a trashed page must not satisfy the
docs requirement for a live compose service. Adds the OKF conformance
and index-freshness tests.

scripts/port-census.py: the port-before-cut orphan census used to prove
a merge lost no fact, kept so the next collapse can re-run it.
2026-10-19 04:54:06 -07:00
Frank e3a02e25c7 docs(LLM): census the decode stall a prefill causes, and the knobs that turn it
Live step-shape census on frank-archon (radiance 1.0.13, boot of 2026-10-15):
decode-only steps run 18.7 ms, prefill+mixed steps 317 ms — 60 % of engine
wall-clock inside 8 % of the steps — and a day of Prometheus shows decode at
13.3 t/s median while prefill runs >=1000 t/s against 106-240 t/s when it does
not. The lag test says the penalty is confined to the prefill window: no
lingering expert-residency tail, and preemptions are zero.

Adds the method as LLM Performance Diagnosis S9 (counter arithmetic, the lagged
bucket correlation that separates step contention from residency churn, and the
four radiance knobs with their published costs), and the endpoint's own numbers
plus the verdict as two frank-archon laws: --busy-prefill-chunk and
--prefill-interleave are absent from this pin (proven via the running
container's --help), so MNBT is the only crank here and an image bump is gated

Frank 30e8ed55a0 docs(frank-zealot): record the ba69ea5 boot ledger and correct the carried credits
The boot of record for the new shape, from the verbosity-4 journal plus
settled nvidia-smi: target KV 14,406.00 (K f16 9,408.00 + V q8_0 4,998.00),
draft KV 2,352.00 over the same 200,704 cells x 3 seqs, recurrent state
452.25, compute 1,665.00 + 424.88 (draft 480.97 + 424.86), weights 2,283.29
+ 257.66, projector 595.29 + 248.10 + 24.93, settled 22,870 used / 1,255
free with n_slots = 3 / n_ctx_slot = 200704.

Two inherited numbers did not survive it, and both are corrected in the env,
the serve rationale and the page:

  - The ubatch 2048 -> 1024 step was quoted at "-~1,306 MiB". That was the
    786,432 / q8_0-pair arm. At THIS shape the target's compute buffers went
    2,496.13 -> 2,089.88: 406 MiB, with CUDA0 going UP 257 while CUDA_Host
    went down 663. q8_0 V (4,410 MiB, not the 3,840 previously written) is
    what funds the drafter, alone.
  - The fit gate priced 22,428 against a real 22,870: conservative by 442
    MiB, so it stays honest as written.

And one finding stated plainly: this is the first boot on this card that
misses llama.cpp's own free-memory target - the engine printed "cannot meet
free memory target of 1,867 MiB, need to reduce device memory by 102 MiB"
and settled at 1,255 MiB free, under the ~2 GiB band every previous era
held. Cheapest rungs back are CTX_SIZE=401408 or SPEC_TYPE=none, both one
line.

Probes on the same boot go in too: chat turn (448 tokens, 1,755 chars of
thinking - empty content at max_tokens 64 is the documented trap), tools
(finish_reason tool_calls, {"a":24,"b":7}), vision (512 px solid red ->
"Red", 280 prompt tokens), and the drafter's own statistics (acceptance
0.706 / 0.763, mean accepted length 2.41 / 2.53).

Frank a7062d1cb3 docs(frank-zealot): carry the 3 x 200,704 shape, retire the exact-KV era row
The endpoint page owns its shape: the flags row, the budget equation behind
it (25,088 B/token, 14,406.00 MiB of cache + 2,352.00 MiB of draft cache
inside 24,123 MiB addressable), the "MTP is ON" section replacing the "OFF by
measurement" one, the harness contract at the per-slot 200,704, and the
fallback rungs rewritten as deltas FROM the shipped shape.

The 2026-10-18 exact-KV boot (KV 16,384.00 / RS 100.50 / compute 1,408.06 +
1,088.07 / mmproj 868.32 charged after the fit check, settled 21,176/2,949)
and its contended rate floors move into that era's Eras row with the one-line
rollback, so the two pages that carried them collapse to one. Rates for the
new shape are deliberately absent - no bench was ordered, and the fit gate,
the health gate and the boot ledger are the evidence a swap needs.

AGENTS.md follows the same numbers: contextWindow 200704 is the per-slot
window and the trio's shape line.

Frank 25a8b00043 feat(frank-zealot): reslice to 3 x 200,704 with q8_0 V and MTP armed
Frank's order, 2026-10-19: --parallel 3 at 200,704 a conversation (pool
602,112), K at the engine default (f16), V to q8_0, batch 1024x6 / ubatch
1024, and the MTP drafter armed explicitly.

The three requests are one budget equation. At 8,192 elements per token per
cache the pair now bills 25,088 B/token = 14,406.00 MiB over the 602,112
pool, and the armed draft context adds its own f16 KV over that whole pool
(4,096 B/position = 2,352.00 MiB) plus buffers and recurrent cells. Dropping
V to the 8-bit class frees 4,410 MiB against exact V and the ubatch drop
hands back ~1,306 - that is what pays for the third slot AND the drafter,
neither of which exact V could fund.

The serve script's written-down fallbacks move with the env so a missing env
file cannot boot the retired shape, and the seam now: asserts the per-slot
contract (divides evenly, <= the trained 262,144), bills an armed drafter in
the VRAM fit gate, proves the gate still REFUSES both boots this shape can
walk into, pins the shipped MTP set (and the absence of --spec-draft-model,
which would load the trunk twice), and pins SPEC_TYPE=none as the rollback
that strips the whole set.

Frankandomp 1ed7f0ddf2 docs(agents): compress Key Lessons to one law per bullet, correct the FA-quants law
Key Lessons Learned 483 -> 340 lines. Every law survives; only the essays
went. Port-before-cut census over the diff: 454 deleted lines, 0 orphaned
facts (every number still has a holder in the vault).

- Each lesson is now one bullet with the page that owns the detail.
- De-duplicated the page's own internal repeats: the layer-split law was
  told twice (PCIe and ROCm sections), the FA-quants law twice more.
- CORRECTION, verified on dankclaw 2026-10-19: `GGML_CUDA_FA_ALL_QUANTS` is
  deprecated upstream (master's ggml/cmake/common.cmake tells you to use
  GGML_CUDA_FA_QUANTS=all), the successor's default pair list
  `q4_0-q4_0;q8_0-q8_0;f16-f16;bf16-bf16` compiles the quantized-KV kernels
  with the old flag OFF (master build-cuda cache: FA_ALL_QUANTS=OFF), and
  neither llama tree references the old macro under ggml/src/ggml-cuda/.
  The "required or prefill collapses ~12x" law is obsolete; the new law is
  to read the CMakeCache pair list.
- frank-zealot: ported the three facts AGENTS.md alone carried, and verified
  them against the host first — the 2026-10-18 13:16 cutover boot really did
  load PTQ1_0 at `new slot, n_ctx = 133888` x3 (journal), the mmproj fit
  check really printed 873.10 MiB against a 21,439 MiB projection, and the
  warmup spread is 2.6 -> 1,258 t/s prefill.
- New tooling: scripts/check-okf.py (OKF v0.1 conformance linter) and
  scripts/gen-vault-index.py (root index regenerated from frontmatter).

## Documentation Policy (fleet law, 2026-10-19)
**One fact, one owner.** A page owns exactly one thing — an endpoint, a
service, or a technique — and every other file links to it with `[[Page]]`.
Restating a shape, a digest, a port list, or a measured number in a second
file is a defect: it is the next thing to go stale.
**Documentation exists for point of use.** A page earns its bytes only if it
helps whoever performs the next task — the shape to deploy, the flag that must
be passed, the failure signature to recognise, the rollback to run. It is not a
lab notebook and not a ledger. **Losing information is an acceptable, usually
correct outcome.** Never let an orphan census ("this is the only copy of that
fact") decide what to keep: sole custody of a useless fact is still useless.
- **One page per endpoint, forever:** `serverAppConfigs-docs/LLM/<endpoint>.md`
— current shape, an **Eras** table (`window | payload | runtime | shape |
replaced because | rollback`), the **Laws** the endpoint taught, the wire
contract, and the files that own it. A payload swap edits the shape block
and appends one Era row. It never creates a page, and the retired era's
page goes to `.AGENTTRASH/` once its rollback path and its laws are in the
table.
- **`log.md` records incidents and laws** — anything with a causal story
(why the host went down, why a knob resets at reboot, why the RAM was the
fault). A model swap is not an incident: it is an Era row and nothing else.
- **`AGENTS.md` carries operator-critical numbers only** — port, context
ceiling, slot shape, unit/env/serve trio — plus the cross-cutting laws.
- **The purpose test — before you write, and again before you keep:** would the
reader act differently because of this line? No → delete it.
- **Measurements are disposable.** A rate or throughput figure (t/s, tok/s, ms,
acceptance %, a bench ladder, a measured MiB) for a payload, runtime, or
layout that is not running now and not being compared now is destroyed, not
filed — not in an Eras row, not on a technique page, not "preserved for
history". AI moves faster than this vault: the number is wrong before anyone
reads it, and a wrong number in a runbook gets believed. Keep the **law** the
measurement taught; drop the measurement.
- **One fact, one owner**, every other file links with `[[Page]]`. The env file
beside the serve script is the authority for every live number; the endpoint
page is the authority for the shape and the wire contract.
- **One page per endpoint:** current shape, **Eras** (`window | payload |
runtime | replaced because | rollback` — the rollback is a commit, not a
number), the **Laws**, the wire contract, the files that own it. A swap edits
the shape block and appends one row; the retired era's own page is
**destroyed** to `.AGENTTRASH/`, never merged into anything.
- **`log.md` is retired** (2026-10-19: 2,380 lines destroyed). Git holds the
chronology. A causal law belongs to the page that owns the thing it governs,
or to *Key Lessons Learned* below if it is cross-cutting — never to a diary.
- **Index pages are locators:** one row, one clause, no numbers.
- **A measured number is written once:** in the env-file header beside the
serve script that consumes it, and in the endpoint page. Every other page
cites it by link.
- Technique pages (spec decode, KV math, offload budgets, PP bandwidth) stay
technique pages: they stop carrying a per-endpoint throughput table or a live
shape, but a campaign ledger that exists nowhere else is owned by the page that
measured it. The defect is two pages carrying one figure, not a number living on a
technique page — move a figure only when an endpoint page or an env header is its
home; otherwise leave it in place and name the era it measured.

**PCIe / multi-GPU**
- **RCCL collectives need PCIe atomics on every participating GPU.** RCCL's
kernels carry a hidden hostcall-buffer parameter; ROCr refuses to dispatch
them when the device has no atomics, and the failure surfaces as
`hipErrorIllegalState` ("the operation cannot be performed in the present
state") from `hipLaunchKernel`, not as anything that names atomics. The
value is consumed at driver probe time, so writing the AtomicOp Requester
bit with `setpci` at runtime changes nothing. Check the *chain*:
`lspci -vv -s <gpu>` and every upstream bridge must show
`AtomicOpsCap: Routing+` (a `Routing-` bridge is a hardware wall), and the
endpoint's Device Control 2 (`setpci -s <gpu> CAP_EXP+28.w`) must have bit
6 set. AMD desktop platforms put one card on CPU root ports (atomics work)
and the rest behind the chipset (usually not) — that asymmetry is what
blocked frank-medium's TP=2. A one-card collective proves nothing: NCCL
short-circuits at `world_size=1`.
- **That wall was physical, and it was fixed on 2026-09-20 by a board swap.**
Both paths that put two cards on CPU root ports were: an M.2→PCIe x4 riser
into a *CPU-attached* M.2 slot, or a board whose CPU lanes bifurcate to
x8/x8. dankserver took the second: **ASUS ProArt B850-Creator WiFi NEO**,
`PCIEX16_1` + `PCIEX16_2` at x8/x8 Gen5 on root ports `00:01.1` / `00:01.3`,
every bridge now `Routing+` and **both endpoints `ReqEn+`** — the exact
precondition the old test plan named. Bandwidth was never the constraint (a
27B TP=2 allreduce at batch 4 is ≈10 MB per token-step, ≈1.4 ms at Gen4 x4
and under 0.4 ms at Gen5 x8).
**Proven on the same day.** vLLM's R4D one-shot allreduce runs TP=2 here and
frank-medium serves on it; llama.cpp's RCCL path was built too
(`GGML_HIP_RCCL=ON`) and its tensor mode measured — real collective, slower
shape. Note the collective choice matters: TheRock's RCCL builds lack gfx1201
device code (`invalid device function`), which is why R4D is the path vLLM
uses at all. Evidence matrix and the measured three-arm verdict:
[[Dual-R9700-Cooperation]].
- **When a GPU collective dies, read the runtime, not the framework.** The
message that identified the cause came from `AMD_LOG_LEVEL=3`
(`Pcie atomics not enabled, hostcall not supported` → `AQL dispatch
failed!`), not from vLLM or RCCL. `AMD_LOG_LEVEL` costs one env var and
prints the failing HIP call with its return code.
- **The software path that puts both cards on ONE model without a collective:
llama.cpp's layer split.** On the old board vLLM could not do it in any of its
parallelisms — TP needs an allreduce, PP needs the same p2p primitive, and both
died on the card that could not dispatch an RCCL kernel. `--split-mode
layer` in llama.cpp needs no
collective: layers are distributed in order and only the boundary activation
crosses PCIe, once per forward pass. Measured here: 1991 t/s prefill /
18.8 tok/s decode layer-split, against 272 / 26.3 tensor (butterfly
fallback).
This was what `frank-medium` ran until 2026-09-20, when the board swap made
collectives legal and radiance TP=2 beat it on every axis (95.8 vs 45.7 t/s
decode, 0.21 vs 0.72 s TTFT, 259 vs 72 t/s burst-4) — see
[[frank-medium-radiance-mxfp4]]; the llama shape is the rollback target
[[frank-medium-llamacpp-dflash2]].
- **Layer split is also the cross-vendor answer — and `-ot` is what cannot be
combined with it.** On Dankclaw (2026-09-16) a CUDA 3090 + Vulkan iGPU layer
split ran a real two-device graph: `-dev CUDA0/Vulkan1 -sm layer -ts 0.15/0.85`
held 14,994 MiB on the 3090 and gave 27.2 tok/s with 268.5 t/s prefill at 64k
depth (iGPU alone: 25.8 / 231.8). What does NOT work is per-tensor placement
across devices: `--override-tensor <group>=<device>` sets
`has_tensor_overrides()`, a REQUIRED term of the scheduler's
`pipeline_parallel` flag (llama-context.cpp:433 — the only place in the tree
that reads it), and that flag is what sets `n_copies` in
`ggml_backend_sched_new`; with `n_copies == 1` a pre-allocated weight on a
non-primary device has no backend and the graph aborts (`ggml-backend.cpp:941`,
reported with the leaf's own op name `(NONE)`). `=CPU` is the only override
target that works, because the CPU backend is last in the list. Pure Vulkan
changes nothing here — the gate is the override, not the driver mix. See
[[x4-pair-experiment]].
- **A host↔3090 link at x4 measures 6.72 GB/s, and that is a design
constraint, not a detail.** `pcie-link-test.cu` on Dankclaw (2026-09-16,
services stopped): pinned H2D 6.72 GB/s, D2H 6.60 GB/s — 85 % of the Gen4 x4
ceiling — with async no better than sync and pageable within 1 % of pinned,
i.e. the copies are link-limited rather than staging-limited (the usual
"pageable costs 2x" rule does not apply here). The card is x16-capable and the
Strix Halo port beneath it is x8-capable (`LnkCap: 16GT/s, Width x8` on
`00:03.1`), so the x4 lives in the adapter or cable; the link idles at
2.5 GT/s x4 and trains up under load. Consequence for any engine that
*streams* weights across it: a 3 MiB slab costs 474 us, and a 111 GiB A3B
model needs ~1.70 GiB of active experts per token ⇒ **3.7 tok/s** (4.6 with a
20 % resident cache), against **20.46 tok/s** for the same model with the
experts *computed* in host RAM by llama.cpp (`-ot exps=CPU`, whence the link
carries activations only) and 25–26.5 on the iGPU. Streaming over PCIe loses;
computing in RAM does not care. FreeToken — expert LRU in host RAM, exactly
this streaming shape — also loads only modelopt block-FP8 safetensors for
`qwen3_5_moe`, so a Q4_K_M GGUF is unloadable there before bandwidth is even
the question. See [[x4-pair-experiment]].
- **RCCL collectives need PCIe atomics on every participating GPU, and the failure never names
atomics.** The kernels carry a hidden hostcall-buffer parameter; ROCr refuses to dispatch them on
a device without atomics and the error surfaces as `hipErrorIllegalState` from `hipLaunchKernel`,
not as anything that names atomics. The value is consumed at driver PROBE time, so writing the
AtomicOp Requester bit with `setpci` at runtime changes nothing. Check the CHAIN: `lspci -vv -s

**ROCm / GPU**
- **Layer split needs no collective** — layers go in order and only the boundary
activation crosses PCIe, so it is the fallback wherever a collective cannot be
dispatched (and on an RCCL-less fork it beats tensor mode, which falls back to
a butterfly allreduce). Pin the spec-decode drafter to one device: an unpinned
draft under tensor mode aborts the KV build, and on a split its home is the
card holding the target's last layers. Deployed history:
[[frank-medium-llamacpp-dflash2]].
- **Bundling a ROCm runtime next to a llama.cpp binary: `cp -r SRC DST/` is a
trap.** With a missing `DST`, cp creates `DST` as a copy of `SRC` and drops
one directory level. rocBLAS and hipBLASLt look for their device code at a
fixed depth (`../lib/rocblas/library`, `../lib/hipblaslt/library/<arch>`),

**Load / crash diagnosis**

not kill the process. `deploy.sh` waits up to 20 minutes (`LLM_WAIT`). On
halogen, the FIRST request after a (re)start can go silent ~45–60 s
(health `engine_unresponsive`, 503s) and then self-recovers — do not
restart over it.
- Crash-loop procedure: (1) `journalctl -u <svc> -n 100` + kernel line via
`journalctl -k` (segfault at address 8 in `libamdhip64` = NULL unref in
HIP); (2) run serve script, then raw binary — different outcome isolates
the env file; (3) `gdb -batch -ex run -ex "bt 25" --args bash
scripts/serve-<svc>.sh` — llama-server buffers stdout and loses the log
tail on SIGSEGV; trust gdb, not the log; (4) `amdgpu: SVM mapping failed`
spam is a symptom, not a root cause.
- Journal signatures: client abort logs `W srv stop: cancel task, id_task =
N`; natural stop logs only `slot release` with `truncated = 0`. The server
never preempts a running generation; excess tasks queue when slots are
busy.

**Host memory / swap**
- Swap resize ordering: create and `swapon` the replacement BEFORE `swapoff`
of the old one, or live pages must land in RAM that `MemAvailable`
overstates. Dankclaw swap (64 GiB at `/swap.img`, fstab-driven) protects
the co-tenants, not frank-dragoon — pinned weights don't swap, and paging
the KV pool is worse than the OOM it prevents.
- Host swap state is invisible to `deploy.sh` (no repo file) — check
`swapon --show` before reasoning about headroom.
- **A sysfs raise is a countdown to the next reboot.** `ttm.pages_limit` defaults
to half of RAM, so the manual raise to 200 GiB (2026-10-05) vanished with the
2026-10-12 23:17 POWER FAILURE on dankserver: the cap fell to 125,988 MiB,
frank-archon's pinned-ledger preflight (floor 150,000 MiB) refused the start,
and `Restart=always` re-ran that refusal **6,919 times in ~20 h** — a unit in
`activating (auto-restart)` that exits 1 in 50 ms with no container and no
engine log is a PREFLIGHT refusal, not an engine fault. Repo law now:
`scripts/ttm-preflight.sh` (sourced by `serve-frank-archon.sh`) raises the knob
to `FRANK_ARCHON_TTM_TARGET_MIB` itself, re-reads, and refuses by name only
after a write the kernel rejected. Never prescribe a manual sysfs write as the
recovery procedure for a service that can boot before a human reaches it.
- **Silent RAM corruption outranks every software theory.** frank-archon's
~40k-token output corruption (2026-10-04/05, repetition/garbage in long
agent conversations) was marginal DDR5 at 4800 MT/s on four DIMMs, fixed
by 4600. Consumer non-ECC memory raises **no MCE** for a silent flip, and
a short in-band pattern check (60 s, 8 GiB of 246 GiB) is not a stability
proof — combined, those two instruments said "ruled out" while the RAM
was the cause. "4800 is the JEDEC floor on 5600-rated DIMMs" is a rating,
not a margin guarantee. When the fault is data-shaped (NaN states,
garbage tokens) and a software revert doesn't move it, price in the RAM
before the runtime — and remember a revert tested under the same marginal
hardware is itself confounded. See the runbook's 2026-10-05 section.

**Runtime-specific guards**
- **Rootless podman cannot RAISE rlimits, and `--ulimit nofile=1048576`
dies at container create, not at runtime.** runc reports
`error setting rlimit type 7: operation not permitted` (type 7 =
RLIMIT_NOFILE) when the requested hard limit exceeds the host process's
hard limit — on Dankclaw that ceiling is 524288. Inherited-equal limits
are fine, so `memlock=-1:-1` works iff the unit grants
`LimitMEMLOCK=infinity` (systemd is privileged; the value flows through
podman to runc without any raise). Upstream halogen's own run lines pass
NO `--ulimit` at all — copy vendor run lines before adding flags
(measured 2026-10-05 on the frank-dragoon cutover).
- **Kairic Edge** (if ever re-deployed): the pinned CK commit needs
`third_party/composable_kernel/include/ck/config.h` generated manually
(untracked; `git clean` removes it), and its greedy-argmax fastpath rejects
non-greedy requests and reasoning budgets. Re-test chat before production.
- **FastMTP sidecar**: build must be commit `4df29be4` + the HauhauCS patch;
stock binaries fail the draft load with a tensor-shape mismatch.
- **A GGUF's custom tensor type picks the runtime — read the histogram before
promising a file to a loader.** `Qwen3.8-27B-Q8_0_ROCMFPX_AGENT.gguf` is
ftype 115 with 311 tensors of type 103 (`GGML_TYPE_Q8_0_ROCMFPX`); stock
llama.cpp and gufo refuse it at load, so ROCmFPX was not a preference but
the only door. Counting tensor types out of the GGUF KV section takes one
python read and settles a runtime argument in minutes. The build identity
matters as much as the fork: the 2026-08-25 ROCmFPX builds SIGSEGV in
`ggml_compute_forward_set_rows` on this same file, so
`scripts/build-rocmfpx.sh` pins commit `36e9acd` by SHA.
- **Speculative-decode flags move as a SET.** Handing the ROCmFPX fork
`--model-draft` with no `--spec-type` (the naive way to build a "no MTP"
bench arm) segfaulted at load, core dumped, no diagnostic (2026-10-02). A
baseline arm must strip `--model-draft` AND every `--spec-draft-*` AND
`--spec-type`, or it measures a crash instead of the absence of drafting.
- **An orphaned scratch server taxes the whole host.** A bench child left
alive by a client-side exception kept ~26 GiB of weights resident on a
121 GiB box, pushed `available` to 3 GiB, and every later rate was suspect.
Record the child pid and kill it in a `finally`, then prove `free` came back
before believing a number. Kill by pid — never `pkill -f llama-server`,
which also hits frank-zealot.
- **Rootless podman cannot RAISE rlimits, so `--ulimit nofile=1048576` dies at container CREATE**,
not at runtime: runc reports `error setting rlimit type 7: operation not permitted` (type 7 =
RLIMIT_NOFILE) when the requested hard limit exceeds the host process's ceiling (524288 on
Dankclaw). Inherited-equal limits are fine, so `memlock=-1:-1` works iff the unit grants

(the naive way to build a "no MTP" bench arm) segfaulted at load, core dumped, no diagnostic. A

**llama.cpp serving**
- **MTP is a property of the FILE, not of the flags.** The `-mtp` GGUF build
carries the head as `blk.<n>.nextn.*` (`qwen35.nextn_predict_layers = 1`);
`--spec-type draft-mtp` then sets `load_mtp`, and the draft context runs on
the MAIN model's weights (`shares_model`), so there is no second copy of a
12 GiB model in VRAM and no `-md` argument. The plain build has no MTP
tensors at all, and pointing `--model-draft` at the file would load it twice.
- **What can be chained, what cannot, and what a chain costs on a hybrid.**
`--spec-type a,b` builds every enabled implementation and chains drafting
through them, in a fixed internal order (ngram types first, then the
drafters — CLI order is irrelevant). The gate is `ctx_dft`: **draftless**
types (the ngram family) are added unconditionally, while `draft-mtp`,
`draft-dflash`, `draft-dspark` and `draft-eagle3` all require a draft
CONTEXT. So a chain may hold one context-backed drafter plus any number of
ngram types — `draft-dflash,ngram-mod` is legal and measured (2.6x the
drafter alone on prompt-echo traffic, byte-identical to it on prose at the
fleet's 48/64 window) — but `draft-mtp,draft-dflash` dies at load: *"context
type MTP requested but model doesn't contain MTP layers"*, because MTP
builds its context against whatever model the draft context holds. Two
context-backed types cannot share one process, and MTP's head only loads
when MTP **is** the draft model. **A LEGAL chain can still lose on a
recurrent model:** `draft-mtp,ngram-mod` on frank-dragoon's qwen35 hybrid
measured −15 % prose / −7 % block-copy (2026-10-03) — adding the ngram layer
logs `recurrent state rollback is not compatible with 'ngram-mod' -
disabling rollback support`, and MTP verification depends on that rollback,
so acceptance drops on ALL traffic even where the matcher fires. Measure
chains per architecture, never by analogy.
- **A drafter's KV scales with the TARGET's context, and its window policy
decides the price.** The draft context is built at `llama_n_ctx(ctx_tgt)` with
no flag to cap it, so a drafter declaring NO sliding window caches the whole
window on `--spec-draft-device` and can OOM the first draft graph capture
AFTER `/health` has answered. Read `sliding_window` out of the drafter's GGUF
header before sizing, and prefer a skewed `-ts` over a context cut. Worked
example: [[frank-medium-llamacpp-dflash2]].
- **A draft context bills its own f16 KV over the WHOLE POOL, and on a
single-card endpoint that squeeze can cost more than the drafter wins.** With
`--parallel N` the drafter pays the pool, not the slot, plus its own compute
buffers. So the MTP question is never "does the file carry the head" but "what
do draft KV + buffers cost against what the batch knobs leave for compute" —
a per-shape answer. Measure the arm, never the flag; the booted arm table is
on [[frank-zealot]].
- **A quant's scale overhead belongs in its byte rate; doubling a measured
figure to "get the f16 number" invents 6.25 %.** q8_0 is 1.0625 B/element
(32 codes + one 2-byte scale per 32-block), f16 is exactly 2.0 ⇒ the ratio is
**1.882×**, not 2×. Derive byte rates from element count × block layout, then
check them against the boot ledger — this repo carried an invented 2× number
for weeks. Current KV math: [[frank-zealot]].
- **`--ubatch-size` has an OPTIMUM, not a plateau, and the curve is
BACKEND-SPECIFIC — never carry it across hosts.** Its compute buffers land
about TWICE as heavy on the card that holds the output layers and the drafter,
so a split balanced at one batch is unbalanced at another: re-measure the
balance after any batch change. The logical `--batch-size` is nearly free.
A large-batch allocation can fail on BUFFER CONTIGUITY while totals still fit
— no totals model can see that. Ladders: [[frank-medium-llamacpp-dflash2]]
(R9700 split) and [[frank-zealot]] (CUDA 3090).
- **On the CUDA 3090 that same knob has no interior optimum up to 2048.** A
prompt shorter than the ubatch cannot see the knob at all — that is the
control that proves the knob, not the traffic, moved the number. When a bench
IS ordered, A/B it by restarting the SERVICE through a transient
`FRANK_ZEALOT_ENV_FILE` drop-in, never a scratch port: one card holds one
server. Numbers: [[frank-zealot]].
- **One `-ts` step is one LAYER, and a hybrid stack's layers are not the same
size** (a DeltaNet boundary and a full-attention boundary can differ by ~1 GiB
each with its own KV), so balance by measurement. An affine fit reproduces the
deployed point and overstates the gaps in between.
[[frank-medium-llamacpp-dflash2]].
- **ngram-mod prints no startup banner.** The load log shows the drafter's
`adding speculative implementation 'draft-dflash'` and nothing at all for the
matcher, so a chain can look unengaged while it is working. Identify it
behaviourally (`draft_n` > 0 only where text repeats) or by the per-task
`draft acceptance = ... mean len = ...` line. It costs no VRAM (a 64 MiB
host-RAM hash table) and its window decides which traffic it can see: too
short and it proposes on ordinary prose fragments, which costs verification
without acceptance.
- **`--parallel` divides the pool, so MORE conversations cost WINDOW, and the
per-slot number is the contract — not `ctx-size`.** `n_ctx_slot =
CTX_SIZE / PARALLEL`, and llama.cpp refuses a prompt longer than the SLOT with
a 400 even when the pool has room, so `models.yml` `contextWindow` must follow
every reslice. Both slot directions cost or buy window, never pool; shorter
slots decode slightly faster (less attention to scan, one fewer recurrent
state). Measured reslices: [[frank-zealot]].
- **Price a VRAM budget from two boots, never from a formula — and an mmproj
costs ~1.5× its file size** (the encoder's activation and compute buffers ride
with it). Subtracting two booted rows isolates it exactly; extrapolating
weights+KV+"a bit for buffers" is what leaves 1.1 GiB free when you meant 2.7.
Then solve `KV ≤ card − non-KV − headroom` and round to a multiple of
`PARALLEL × 4096`. The two-boot table: [[frank-zealot]].
- **`images` and `image_url` are NOT interchangeable: only the content part
reaches the model.** `--mmproj` loads, `usage.prompt_tokens` rises, and the
model still invents an answer if the client used the legacy top-level
`images` field on `/v1/chat/completions` — frank-zealot answered "Brown." for
a solid-red PNG that way and "Red." through the OpenAI `image_url` part. The
failure is silent because a hallucinated color is a plausible answer. Probe
vision with a solid color and expect an exact word.
- **`--jinja` is what `tools` needs.** On 2026-09-16 a subagent died with
`500 tools param requires --jinja flag`, from the ik_llama.cpp runtime that
then served frank-dragoon: every tool-using agent on that endpoint was broken
and the failure read like a model fault. Mainline llama.cpp 0.4.1 defaults
`--jinja` on and the serve script pins it; halogen also accepts `tools` and
returns `tool_calls`. Check tool support before routing a role at an endpoint.
- **Quantized KV on CUDA needs `GGML_CUDA_FA_ALL_QUANTS=ON`** — the same
option and the same ~12x prefill collapse described in the ROCm note above.
f16 KV needs nothing; frank-zealot ran f16 for that reason until
2026-09-17, when `build-cuda` was rebuilt with the option ON so the
endpoint could take q8_0 KV.
- **llama-bench separates a LIST with `/` and SWEEP values with `,`.** Both
`-dev` and `-ts` follow this: `-dev CUDA0,Vulkan1` is two *single-device*
configurations, never one two-device run, and `-ts 0.85,0.15` is two sweep
values each becoming `[0.85, 0, …]` / `[0.15, 0, …]`, i.e. device 0 takes
everything. Write `-dev A/B -ts x/y`. This artifact produced a wrong fleet
conclusion on 2026-09-16 — "CUDA + Vulkan cannot serve one model", with two
bogus OOMs that were really "all 111 GiB on the 24 GiB card" — and the bench
table's own `dev` column was printing the truth the whole time. Any
placement-dependent number needs an independent check: sample the other
- **MTP is a property of the FILE, not of the flags.** The `-mtp` export carries the head as
`blk.<n>.nextn.*` (`qwen35.nextn_predict_layers = 1`); `--spec-type draft-mtp` sets
`load_mtp` and the draft context runs on the MAIN model's weights (`shares_model`), so there
is no second copy of a 12 GiB model in VRAM and no `-md` argument. The plain build has no MTP
tensors at all, and pointing `--model-draft` at that file loads it twice. [[frank-zealot]]
- **What can be chained: ONE context-backed drafter plus any number of draftless ngram types.**
`--spec-type a,b` chains in a fixed internal order (CLI order irrelevant) and the gate is
`ctx_dft`: the ngram family is added unconditionally while `draft-mtp`, `draft-dflash`,
`draft-dspark` and `draft-eagle3` all need a draft CONTEXT. So `draft-dflash,ngram-mod` is
legal and it wins on prompt-echo traffic, but `draft-mtp,draft-dflash`
dies at load — *"context type MTP requested but model doesn't contain MTP layers"*. **A LEGAL
chain can still lose on a recurrent model:** `draft-mtp,ngram-mod` on frank-dragoon's qwen35
hybrid loses, because adding the ngram layer logs
`recurrent state rollback is not compatible with 'ngram-mod' - disabling rollback support` and
MTP verification depends on that rollback. Measure chains per architecture, never by analogy.

- **A drafter's KV scales with the TARGET's context, and its window policy decides the price.**
The draft context is built at `llama_n_ctx(ctx_tgt)` with no flag to cap it, so a drafter
declaring NO sliding window caches the whole window on `--spec-draft-device` and can OOM the

the failure names Jinja, not the model: every subagent on `frank-zealot` died with
`Unexpected reasoning effort high` until `high: xhigh` was added. Halogen accepts the wider
set, so the two entries legitimately differ.
- **Thinking tokens count against `max_tokens`, so a short-budget vision probe reads as
blindness.** A probe at `max_tokens: 64` returned `content: ""` with `finish_reason: "length"`
and half a thought in `reasoning_content` while the image HAD reached the model (322 prompt
tokens vs 42 for the text alone). Budget ≥512 for any thinking model you probe for vision.
- **The FIRST request after a boot is a warmup artifact**, and the 3× spread on one shape makes
graph-capture cost read as a model fault. Benchmark the second request or later.
[[frank-zealot]]
- **A fork build hides its own dtype laws.** Vendor builds carry their own compile options, so
prove a build's KV behaviour from the KV buffer line in the boot ledger and its
`CMakeCache.txt` — never from the build flags you remember passing. [[frank-zealot]]
- **A llama.cpp endpoint is invisible to Prometheus unless `--metrics` is passed**: without it
the engine answers **501 Not Implemented** on `/metrics`, so the scrape fails while `/health`
answers 200 and `LlmEndpointDown` fires beside a healthy service. halogen serves `/metrics`
natively, so the asymmetry reads as "only the 3090 is broken". Diagnose with `lastError` from
`/api/v1/targets`, not the alert list, and note Alertmanager has no persistence: a reboot
re-stamps `startsAt` on an alert that has fired for weeks. [[Observability]] [[frank-zealot]]
- **A leftover bench drop-in silently hijacks the next deploy, and no health gate sees it.** The
sanctioned bench-window method (a transient `Environment=FRANK_<SVC>_ENV_FILE=/tmp/<arm>.env`
drop-in sourcing the repo env) outlives the bench unless retired: a leftover
`frank-zealot.service.d/ptq1.conf` made the cutover deploy boot a **different model at a
different shape** while `/health` answered 200, `/v1/models` echoed the alias (a flag, not a
fact) and the Playwright gate passed 33/33. After deploying any recently-benched LLM service:
`systemctl show <svc> -p DropInPaths` (must be empty), then
`tr '\0' ' ' </proc/$(pidof llama-server)/cmdline`, then the boot ledger — and retire drop-ins
to `~/.AGENTTRASH/<date>-<topic>/` + `daemon-reload`. [[frank-zealot]]
- **A bench verdict that never reaches the repo is indistinguishable from a rogue arm.** That
same arm served production for 24 minutes with real numbers (~48 t/s decode, 801 t/s prefill at
141k) that lived only in `/tmp` env files and journald, so the next agent read the surviving
drop-in as an unfinished experiment and reported a hijack. Write the measurement into the
endpoint page and the arm script's header in the session that takes it — `/tmp` and the journal
are not records.
- **`llama-bench` separates a LIST with `/` and SWEEP values with `,`** — for both `-dev` and
`-ts`. `-dev CUDA0,Vulkan1` is two *single-device* configurations, never one two-device run,
and `-ts 0.85,0.15` is two sweep values each putting everything on device 0. Write
`-dev A/B -ts x/y`. This artifact produced a wrong fleet conclusion ("CUDA + Vulkan cannot serve
one model") from two bogus OOMs, and the bench table's own `dev` column was printing the truth
the whole time. Any placement-dependent number needs an independent check: sample the other
device's memory (`nvidia-smi`) while the run is loaded.
- **A model's own template can REJECT the harness's thinking level.** Qwen3.8's
template accepts only `xhigh`, `medium` and `low` for `reasoning_effort` and
raises on anything else — HTTP 500, not a clamp — so the harness's levels
must be folded onto that set in `models.yml` (`compat.reasoningEffortMap`).
A role whose level is unmapped fails on its FIRST request, and the failure
names Jinja, not the model: every subagent on `frank-zealot` died with
`Unexpected reasoning effort high` until `high: xhigh` was added on
2026-09-16. Halogen accepts the wider set, so the two entries legitimately
differ.
- **The vision projector is NOT billed in llama.cpp's own fit check.** The
engine prints `[mtmd] estimated worst-case memory usage of mmproj is
873.10 MiB` and then fits WITHOUT it: frank-zealot's Bonsai-2 boot projected
21,439 MiB and settled at 22,664 (2026-10-17). Price a 3090-class shape from
settled `nvidia-smi` after a real boot, never from
`model + context + compute` — the projector (and any drafter context) lands
after `/health` would already have answered. Same failure class as the
DSpark drafter OOM.
- **The FIRST request after a boot is a warmup artifact.** Measured on
Bonsai-2/3090: 2.6 t/s prefill and 37.7 t/s decode on request #1, then
1,258 t/s prefill and 54.7 t/s (per stream, two concurrent) on the next — a
3× spread on the same shape. Benchmark the second request or later, or the
graph-capture cost reads as a model fault.
- **Thinking tokens count against `max_tokens`, so a short-budget vision probe
reads as blindness.** The Bonsai-2/`image_url` probe at `max_tokens: 64`
returned `content: ""` with `finish_reason: "length"` and half a thought in
`reasoning_content` — the image HAD reached the model (322 prompt tokens vs
42 for the text alone). At 512 tokens the same image answers "Red". Budget
≥512 for any thinking model you probe for vision.
- **Quantized KV is not the only dtype law a fork build can hide.** Vendor
builds carry their own compile options: frank-zealot's PrismML prebuilt
served `--cache-type-v q8_0` under flash attention at the exact 34,816
B/token (the `GGML_CUDA_FA_ALL_QUANTS` door), so a build decision must be
proven by the KV buffer line in the boot ledger, not by the build flags you
remember passing.
- **A llama.cpp endpoint is invisible to Prometheus unless `--metrics` is passed.**
Without it the engine answers **501 Not Implemented** on `/metrics`, so the scrape
fails while `/health` answers 200 and `LlmEndpointDown` fires beside a healthy
service — that is how `frank-zealot` sat red across four payload generations
(the oldest retained sample of `up{job="frank-zealot"}`, 2026-10-11, is already
0). halogen serves `/metrics` natively, so the asymmetry reads as "only the 3090
is broken". Diagnose with `lastError` from `/api/v1/targets`, not the alert list,
and note Alertmanager has no persistence: a reboot re-stamps `startsAt` on an
alert that has been firing for weeks.
- **A leftover bench drop-in silently hijacks the next deploy, and no health
gate sees it.** The sanctioned bench-window method — a transient
`Environment=FRANK_<SVC>_ENV_FILE=/tmp/<arm>.env` drop-in, the arm env
`source`ing the repo env and then overriding it — outlives the bench unless
it is retired. On 2026-10-18 a leftover `frank-zealot.service.d/ptq1.conf` —
the arm Frank had ordered at 02:36 and measured from 03:14 — made the cutover
deploy boot a **different model at a different shape** (3 slots of 133,888,
not 3 × 262,144) while `/health` answered 200, `/v1/models` echoed the alias
(a flag, not a fact) and the Playwright gate passed 33/33. After deploying any
recently-benched LLM service: `systemctl show <svc> -p DropInPaths` (must be
empty), then `tr '\0' ' ' </proc/$(pidof llama-server)/cmdline`, then the boot
ledger — and retire drop-ins to `~/.AGENTTRASH/<date>-<topic>/` +
`daemon-reload`.
- **A bench verdict that never reaches the repo is indistinguishable from a
rogue arm.** Same window: PTQ1_0 served production for 24 minutes with real
numbers (~48 t/s decode, 801 t/s prefill at 141k), but the figures lived only
in `/tmp` env files and journald, so the next agent on the host read the
surviving drop-in as an unfinished experiment and reported a hijack. Write the
measurement into the runbook and the arm script's header in the session that
takes it — `/tmp` and the journal are not records.
**Ops**
- Never `pkill -f` a pattern that appears in your own command line — it kills
your ssh session. Use `pkill -x <exact-name>`.
- Both hosts allow passwordless sudo for the deploy user. Use plain `sudo` in
committed scripts (no `echo pw | sudo -S`); `FRANK_SUDO_PW` covers hosts
without it.
- ComfyUI on Dankclaw runs with **GPU access** (`/dev/kfd` + `/dev/dri` via
`AddDevice`, `GroupAdd=keep-groups`, plus the udev rule that makes those nodes
world-writable — user-unit spawns carry no supplementary groups). It must NOT
pass `--cpu`: the gfx1151 ROCm wheels exist and the unit's `--cpu` era ended
2026-09-16, when a stale device-less container was found restarted 9,146
times (`RuntimeError: No HIP GPUs are available`).
- SearXNG outbound traffic must stay on the Gluetun tunnel; do not move its
ports off the gluetun service.
- Dankclaw boots **`iommu=pt`** since 2026-10-18. The boot line is tracked in
`dankclaw/host/grub` and moves ONLY through `scripts/set-dankclaw-bootline.sh`
(diff, install, `update-grub`, verify `grub.cfg`, `--reboot`) — never by
hand-editing `/etc/default/grub`. It replaced `amd_iommu=off` (2026-09-11),
adopted on the vendor's 13–16 % prefill figure and never measured here: the
local A/B on byte-identical traffic says identity mode costs **nothing**
(+2.0 %, 1,616 t/s cold prefill), so the XDNA2 NPU returned for free —
`amdxdna` binds `c6:00.1` (PASID width 10, identity group 26) and the old
`err=-19` only ever asked for an enabled IOMMU. **AMD PerfOpt** (iommu tree
2026-09-24, Linux 7.4) still skips the page walk outright for the privileged
iGPU, but it arms only in the identity domain and 26.04 caps at `7.0.0-38`.
- Rootless Quadlet containers run with `--replace --rm`: `podman logs` covers
only the CURRENT instance; history across recreations lives in
`journalctl --user -u <name>.service`. Read rootless storage WITHOUT sudo
(per-user storage — `sudo podman logs` finds nothing).
- **A dead rootless podman pause process breaks ALL container management on the
host, and `podman system migrate` panics in 5.7.0.** Symptoms: every `podman`
command fails with `invalid internal status … could not find any running
process`, every container start fails binding podman's bridge addresses
(`Error starting server failed to bind udp listener on 10.89.x.1:53: Cannot
assign requested address`), and every `Restart=always` quadlet loops. Container
storage is intact; what is gone is `/run/user/<uid>/libpod/tmp/alive` (a UUID
token, not a pid) and the rootless netns holding the bridges — deleting the
stale token is not enough, and `podman system migrate` segfaults in
`teardownNetworkBackend`. Repair: **reboot** (`/run/user` clears and all 28
quadlets return on their own — check `Linger=yes` and `WantedBy=default.target`
first). Seen 2026-09-16, hours into heavy GPU work on the same host — but the
trigger is NOT established (`journalctl -k` recorded no OOM kill; the kernel
had no other word on it). Treat the pause process as host state that can die
for its own reasons, and reach for the reboot when it does.
- **A container cannot reach a `Network=host` service at the host's LAN IP.**
netavark DNATs *published* ports only: from a bridge container
`192.168.0.143:<published>` answers while `192.168.0.143:<host bind>` and the
gateway `10.89.1.1` are both refused. Use `host.containers.internal`
(169.254.1.2). This is what 502'd `hermes.franksdank.cloud` until the Caddyfile
upstream was changed on 2026-09-16 (its vhost comment had claimed the LAN IP
was open from that bridge — it never was).
- **A `*.gguf` filter misses mradermacher's payloads: large quants ship as
`.partNofM` fragments.** `mradermacher/Qwen3.8-Flash-Next-Uncensored-i1-GGUF`
carries Q4_K_M (37.00 + 37.00 + 36.97 = 110.97 GiB) and Q4_K_S (35.00 + 35.00
+ 34.09 = 104.09 GiB) as parts, while the smaller rungs (Q2_K, Q3_K_*, IQ3_*,
IQ4_XS) are single files. Fetch the parts, verify each against the Hub's LFS
sha256, concatenate in numeric order — that is how the deployed 111 GiB file
was assembled. Listing the Hub tree and filtering `endswith(".gguf")` makes
Q4_K_S look like it does not exist.
- **A fetch script must `-f` and verify, or it reports success on an access
error.** `curl -o FILE URL` exits 0 on HTTP 401/403 and writes the error body
as the "artifact": a gated repo yielded three 153-byte shards with identical
sha256 values and a cheerful `DOWNLOAD_DONE` in 20 seconds for 104 GiB. Use
`-f`/`--fail-with-body`, compare each file's byte count to the Hub's declared
size, and check the LFS sha256 — `scripts/download-frank-medium-gguf.sh`
already does all three; ad-hoc fetches tend not to. Gated repos (e.g.
`orcarouter/Qwen3.8-Flash-Next-Uncensored-GGUF`, same 104.09 GiB Q4_K_S)
return 403 even with the host's HF token until that account accepts the gate.
- **A scout verdict is a lead, never a finding.** In the 2026-10-19 vault de-dup
campaign, four read-only scouts worked the same pages: one classified era pages as
stale *because* they document retired payloads (that is an era page's content), one
reported files that do not exist, one reported duplications that grep disproved
(`457.9 t/s` and the ping-RTT table are solo-held by `Ethernet Bandwidth Math`),
and one cited a line number past the end of the file it judged. Re-verify every
claimed duplicate and every claimed staleness against the file and today's fleet
state before editing; a scout yield buys no evidence.
- Never `pkill -f` a pattern that appears in your own command line — it kills your ssh session.
Use `pkill -x <exact-name>`.
- Both hosts allow passwordless sudo for the deploy user. Use plain `sudo` in committed scripts
(no `echo pw | sudo -S`); `FRANK_SUDO_PW` covers hosts without it.
- **ComfyUI on Dankclaw runs with GPU access** (`/dev/kfd` + `/dev/dri` via `AddDevice`,
`GroupAdd=keep-groups`, plus the udev rule that makes those nodes world-writable — user-unit
spawns carry no supplementary groups) and must NOT pass `--cpu`: the gfx1151 ROCm wheels exist
and a stale device-less container was found restarted 9,146 times. [[ComfyUI]]
- SearXNG outbound traffic must stay on the Gluetun tunnel; do not move its ports off the gluetun
service. [[SearXNG]] [[Gluetun]]
- **Dankclaw's kernel command line is a repo file.** It boots **`iommu=pt`** since 2026-10-18,
tracked in `dankclaw/host/grub`, and moves ONLY through `scripts/set-dankclaw-bootline.sh`
(diff, install, `update-grub`, verify `grub.cfg`, `--reboot`) — never by hand-editing
`/etc/default/grub`. It replaced `amd_iommu=off`, and the local A/B on byte-identical traffic
says identity mode costs nothing, so the XDNA2 NPU returned for free.
[[dankclaw-iommu-translation-off]]
- **Rootless Quadlet containers run with `--replace --rm`**: `podman logs` covers only the CURRENT
instance; history across recreations lives in `journalctl --user -u <name>.service`. Read
rootless storage WITHOUT sudo — it is per-user storage, so `sudo podman logs` finds nothing.
[[Quadlet Lifecycle]]
- **A dead rootless podman pause process breaks ALL container management on the host, and
`podman system migrate` panics in 5.7.0.** Every `podman` command fails with
`invalid internal status`, every start fails binding the bridges
(`failed to bind udp listener on 10.89.x.1:53`), every `Restart=always` quadlet loops — while
container storage stays intact. What is gone is `/run/user/<uid>/libpod/tmp/alive` (a UUID
token) and the rootless netns; deleting the stale token is not enough. Repair: **reboot**
(`/run/user` clears and the quadlets return on their own — check `Linger=yes` and
`WantedBy=default.target` first). The 2026-09-16 occurrence had no OOM in `journalctl -k`:
treat the pause process as host state that can die for its own reasons. [[Quadlet Lifecycle]]
- **A container cannot reach a `Network=host` service at the host's LAN IP**: netavark DNATs
*published* ports only, so the host bind and the `10.89.1.1` gateway are both refused from a
bridge container while the published port answers. Use `host.containers.internal`
(169.254.1.2). This 502'd `hermes.franksdank.cloud` until its Caddyfile upstream changed.
[[Container Host Reachability]]
- **A `*.gguf` filter misses mradermacher's payloads: large quants ship as `.partNofM`
fragments** while the smaller rungs are single files, so filtering `endswith(".gguf")` makes a
whole quant class look absent. Fetch the parts, verify each against the Hub's LFS sha256,
concatenate in numeric order. [[Model Swap and Rollback]]
- **A fetch script must `-f` and verify, or it reports success on an access error.**
`curl -o FILE URL` exits 0 on HTTP 401/403 and writes the error body as the "artifact": a gated
repo yielded three 153-byte shards with identical sha256 and a cheerful `DOWNLOAD_DONE` in 20
seconds for 104 GiB. Use `-f`/`--fail-with-body`, compare each file's byte count to the Hub's
declared size, and check the LFS sha256 — the live `scripts/download-frank-*.sh` scripts do
all three; ad-hoc fetches tend not to. Gated repos 403 even with the host's HF token until
that account accepts the gate. [[Model Swap and Rollback]]
- **A verdict is a lead — the scout's and the tool's alike.** In the 2026-10-19
documentation campaign six scouts worked the same pages and produced invented
bullet IDs, files that do not exist, "duplications" grep disproved, line
numbers past the end of the file they judged, and Eras tables with invented
payloads. The mechanical tool was worse: `scripts/port-census.py` built its
corpus from the directory containing the page under test, so each page was held
by *itself* and ten era pages reported "0 sole-record lines" — which reads as
"pure duplication, trash it". Nothing was cut on a verdict; every holder was
re-grepped and every tool re-measured before it was believed.
- **Never let a census decide what to keep.** That same campaign then concluded
the era pages were irreplaceable because each held 14–63 sole-record lines —
wrong in the opposite direction: those were throughput figures for payloads that
no longer run. Point of use is the only ownership test, the operator applies it,
and 53 pages plus the 2,380-line change diary were destroyed as a result. A tool
can say where a fact lives; it cannot say whether anything needs it.

# XDNA2 NPU inference runtimes on Linux (Strix Halo) — can any of them serve TTS?
Research slice, 2026-10-19. Worker: `NpuRuntimeLandscape`. Research only, no code.
Question: every way to execute model inference on an AMD XDNA2 NPU on Linux as of
2026-10, and whether any of them can serve a speech-synthesis model.
> **Status, same night — the spike that followed this slice settled it.** NO-GO on the
> NPU (the loader declines the graph, not the silicon); the actionable door is the gfx1151
> iGPU behind `-DGGML_VULKAN=ON`. Measured contract, exoneration chain and host gates:
> `tts-npu-spike-verdict-2026-10-19.md`. That page supersedes §8–§9 below.
Convention: vendor claims carry URL + the version/date they hold for.
**[host]** = Dankclaw state verified on the live machine 2026-10-19 (Main), not a
vendor claim. `[INFERENCE]` = my deduction from the cited artifacts.
## 0. Answers to the three questions Main ranked
**(1) A runtime that already runs TTS on XDNA2 today: it exists at AMD, not on our
host.** Ryzen AI Software **1.8.0** (docs `latest` == 1.8.0; released 2026-07-23)
lists `neutts-air` and `neutts-nano` as model type **TTS**, variant
*full-optimized* (NPU-only) — <https://ryzenai.docs.amd.com/en/latest/llm_list.html>;
release note "New TTS model support: neutts-air, neutts-nano" —
<https://ryzenai.docs.amd.com/en/latest/relnotes.html>. Pre-compiled artifacts are
published: `amd/neutts-air_rai_1.8.0_npu_4K` (arch `qwen2`, lastModified
2026-07-23, Apache-2.0, "AWQ / Group 128 / Asymmetric / BFP16 activations / UINT4
Weights") and `amd/neutts-nano_rai_1.8.0_npu_4K` (arch `llama`).
**Neither artifact is a TTS engine.** Both file lists are LM-only (`model.onnx`,
`genai_config.json`, BPE tokenizer, AIE-ML compiler metastate: `dd_metastate_*`
`.ctrlpkt/.super/.state`, `cache/txn_bins.zip`) with **no codec, no vocoder, no
reference-audio encoder**. [INFERENCE from HF file lists]
**(2) FastFlowLM: no TTS, and we cannot add one** — see §2. Halogen: no TTS entry
**[host]**. So "something installed already serves TTS on the NPU" is FALSE.
**(3) Our own ONNX graph compiled for the NPU on Linux:** possible for the plain
ONNX flows (they compile on Linux), **impossible for a new LLM/OGA model** — model
generation is Windows-only in 1.8.0 — and gated by an operator table where BF16
lacks Softmax/LayerNorm/ReLU/Gelu (see §4).

→ **A new TTS architecture cannot be added to `flm` by us.**
## 3. AMD Ryzen AI Software 1.8.0 on Linux — install source, device support
* **Install channel (important correction to the pypi.amd.com evidence).** The pip
index is Windows-only for the EP runtime (`ryzenai_dynamic_dispatch-1.7.0-…
win_amd64.whl`, `onnxruntime_vitisai-1.23.2-…win_amd64.whl`; `flexmlrt` has a
single **linux_aarch64** wheel) — but AMD's Linux stack is not on pip. It ships
as a tarball that is, as of 2026-10-19, **publicly reachable without an AMD
account**: `https://download.amd.com/opendownload/RyzenAI/1.8.0/ryzen_ai-1.8.0.tgz`
→ HTTP 206 on a range probe, `Content-Range: bytes 0-8/**7819506855**`
(**≈7.8 GiB**, magic `1f 8b 08` = gzip). (The docs link it behind the
EULA form `account.amd.com/...ryzenai-eula-public-xef.html`; the CDN path
serves it directly. Verified by me with curl 2026-10-19. I did not finish
downloading 7.8 GiB, so the tarball's *contents* list is unverified —
`[INFERENCE]` only where noted.)
* Driver/XRT package (public, 90,016,137 bytes, `application/zip`):
`https://download.amd.com/opendownload/RyzenAI/Driver/RAI_1.8_Linux_NPU_XRT.zip`
contains `xrt_202620.2.25.37_24.04-amd64-{base,base-dev,npu}.deb` +
`xrt_plugin.2.25.260102.56.release_24.04-amd64-amdxdna.deb` (verified by
download + unpack). **The plugin deb ships firmware for
`/usr/lib/firmware/amdnpu/17f0_11/npu.dev.sbin`** — exactly the directory our
NPU loads **[host]** — plus `1502_00`, `17f0_10`, `17f1_10`, `17f1_13`,
`libvxdna.so`, `libxrt_driver_xdna.so.2.25.260102.56`, and the DKMS driver
source tarball. **No xclbin/PDI and no compiler binary in this package**: it is
driver + XRT shim + firmware only.
* **Our device is officially STX.** AMD's APU table
(<https://ryzenai.docs.amd.com/en/latest/app_development.md#apu-types>):
`0x1022:0x17F0 rev 0x11 → STX` (0x00/0x10 also STX, 0x20 = KRK, `0x1502` rev 0
= PHX/HPT). Release notes: "Strix and **Strix Halo** as STX", and the STX/KRK
column enables CNN INT8, CNN BF16, NLP BF16, LLM (OGA).
* Vendor driver source (same deb, `share/amdxdna/amdxdna.tar.gz`, source dated
2026-06-29) maps `0x17f0 rev 0x11 → dev_npu5_info`, `.fw_path =
"amdnpu/17f0_11/"`, `default_vbnv = "RyzenAI-npu5"`, and the revision→name table
has `{ AIE2_DEV_REVISION_HALO, "NPU Strix Halo" }`; `xrt-smi examine` therefore
reports the device as **NPU Strix Halo**.
* Linux install recipe (1.8.0 docs
<https://ryzenai.docs.amd.com/en/latest/linux.html>): Ubuntu 24.04 packages,
**Python 3.12** (`apt install python3.12 python3.12-venv`),
`libboost-filesystem1.74.0`, dkms; then `install_ryzen_ai.sh -a yes -p <venv>`;
`LD_LIBRARY_PATH=…:${RYZEN_AI_INSTALLATION_PATH}/onnxruntime/lib/`;
`quicktest.py` "picks up a simple CNN model, **compiles it** and runs on AMD's
Neural Processing Unit" — i.e. **compilation runs on Linux** for the non-LLM
flows. "Linux currently supports NPU only flow" (no iGPU EP).
Host friction: our box is Ubuntu 26.04 + **Python 3.14** **[host]**, so the venv
must be built with a 3.12 interpreter and the packages are 24.04-built
`[INFERENCE]`.
* LLM flow on Linux
(<https://ryzenai.docs.amd.com/en/latest/llm_linux.html>): prequantized
ready-to-run models from HF, `deployment/lib`,
`RYZENAI_EP_PATH=$PWD/deployment/lib/libonnxruntime_providers_ryzenai.so`,
run via the `model_benchmark` binary; **"Linux does not support Hybrid flow"**;
**"Model generation is not supported in current release"** (repeated in
relnotes 1.8 Known Issues: "Models generated on Windows are compatible with
Linux"); needs `memlock unlimited`.
Sample throughput in that doc: **49.1 tokens/s decode**, 753 tokens/s prefill
(Phi-3.5-mini, 4K model).
* Third-party confirmation of the OS split: Lemonade's backend matrix
(<https://raw.githubusercontent.com/lemonade-sdk/lemonade/main/README.md>,
fetched 2026-10-19) — `flm`/npu/XDNA2 = **Windows, Linux**;
`ryzenai-llm`/npu = **Windows only**; `whispercpp`/npu (STT) = **Windows only**;
text-to-speech engines `kokoro` and `acestep` = metal / cuda / vulkan / rocm,
**no npu device at all**. Lemonade is the "Server Interface" layer of AMD's own
Ryzen AI stack (docs index), so this matrix is the vendor-sanctioned view.
## 4. Can we compile our own graph on Linux? (the no-recipe path)
Mechanics from <https://ryzenai.docs.amd.com/en/latest/modelrun.md> (1.8.0):
ONNX only, opset 17 recommended; the EP compiles on first `InferenceSession` and
caches (VitisAI EP cache, or ORT **EP context cache** — `ep.context_enable`, and
"precompile the EP context model using Python and deploy it using a C++ program"
is explicitly supported); EP auto-partitions unsupported nodes to CPU;
BF16 = `target VAIML` (`preferred_data_storage: unvectorized` for transformers),
BF16 **STX/KRK-or-newer only**; INT8 = `target=X2` with XINT8/A8W8/A16W8 and
"general asymmetric quantization … to enable third-party quantized models";
**deployment EP cannot compile BF16 on the fly** — ship a pre-compiled model
(<https://ryzenai.docs.amd.com/en/latest/app_development.md>);
cache dirs are not portable across EP or NPU-driver versions.
Operator coverage is the hard gate
(<https://ryzenai.docs.amd.com/en/latest/ops_support.md>, "operators supported in
Ryzen AI 1.8.0"; "Y" = broad coverage, some configurations may still fail):
* Good for TTS front-ends/vocoders: `ConvTranspose` **Y in BF16/A16W8/A8W8**
(absent only from XINT8), `Conv`, `Resize`, `Upsample`, `Pad`, `LSTM` (BF16),
`CumSum` (BF16/XINT8), `STFT` (XINT8 only).
* **Blockers for a decoder-style transformer in the plain flows:** in **BF16** the
table has **no Softmax, no LayerNormalization, no Relu/Gelu**; LayerNorm is
XINT8-only and Softmax is A16W8/A8W8/XINT8-only. So attention either lives in
the **LLM/OGA flow** (whose op set is exactly
`SimplifiedLayerNormalization`, `SkipSimplifiedLayerNormalization`, `MatMulNBits`
(W4ABF16/W4ABFP16), `RotaryEmbedding`, **`GroupQueryAttention`**, `Sigmoid`,
`Mul`, `Add`) or must be decomposed into a quantized INT8 flow.
* Missing entirely: `GRU`, `Trilu`, `OneHot`, `EyeLike`, `Multinomial`,
`NonMaxSuppression`, `CastLike`, `MelWeightMatrix`/`MelFilterGroup`,
`RMSNormalization` → graphs that emit them must be rewritten before they
partition onto the NPU. [INFERENCE from absence in the table.]
* Quantization is a separate tool, not in the driver package: **AMD Quark**
(`quark.torch` / `quarkonnx`), which documents `ConvTranspose2d`, `conv1d`,
softmax/LayerNorm/BFP quantization (relnotes 1.3/1.2/1.1/0.9) — Quark is *not*
on pypi.org under the obvious names **[host probe]** and ships from AMD's
gated/pip-private channel.
* **New LLM-shaped model (our Qwen-Talker analogue): Windows-only today.**
OGA model generation is not available on Linux in 1.8.0 (§3). So a *new*
speech-LM cannot be self-served onto the NPU on Linux without AMD (or a
Windows box) in the loop.
* Practical shape cost: the neutts artifacts carry **one compiled variant per
padded sequence length** (128/256/512/768/1024/1536/2048/2304/3072/4096 for
prefill; 256…4096 for token-phase attention mask) — i.e. per-shape compile
artifacts are the norm for the LLM flow. [INFERENCE from the HF file list.]
## 5. Does the AMD TTS artifact actually produce speech? (cloned-voice survival)
NeuTTS is **LM + separate neural codec** ("Simple LM + codec architecture"),
clone from ~3 s of reference audio, and the codec is **NeuCodec (50 Hz, single
codebook)**: `neuphonic/neucodec` (PyTorch, encode+decode),
`neucodec-onnx-decoder{,-int8}` (**decode only**), "Decoder-only (ONNX) codecs
require **pre-encoded references** — these ship with the repo for all bundled
voices." Phoneme input; 2048-token context ≈ 30 s of audio; NeuTTS-Air ~360 M
active / 552 M with embeddings; upstream benchmarks are **CPU-only llama.cpp**
(119 tok/s prefill/decode mix on a Ryzen 9 HX 370) and explicitly exclude the
codec. <https://raw.githubusercontent.com/neuphonic/neutts/main/README.md>
(fetched 2026-10-19); `neuphonic/neutts-air` HF metadata (lastModified
2026-08-26, `qwen2`, GGUF + safetensors).
Consequences for the fleet spike:
1. AMD's NPU artifact = LM only; **waveform decode and reference encoding are CPU
work either way**. Our `reference.wav` voices survive only if we run the
NeuCodec **encoder** (PyTorch, per the codec table there is no ONNX encoder)
once per voice and then feed pre-encoded codes. That is a one-time offline
step per voice; after that the compiled graph takes codes/prompt prefix as
ordinary inputs, so nothing about the compiled graph forbids a caller-supplied
speaker prefix. `[INFERENCE]`
2. Real-time math: 50 Hz codec means **≥50 tokens/s decode** for 1× RT. AMD's own
Linux sample output for a 4K Phi-3.5-mini is **49.1 tok/s** — so budget for
roughly RT-1× on one 4K "full fusion" graph, before the codec's CPU cost.
`[INFERENCE — different model; must be measured.]`
3. Host RAM: the same doc reports **peak working set 3.54 GB** for that 4K model.
NeuTTS-Air is ~552 M params at W4A-BFP16, so expect a smaller footprint than
3.5 GB `[INFERENCE]`; still non-trivial against 14 GiB available **[host]**.
4. AMD ships **no TTS demo, runner, or server** on any OS: the examples page has
only CNN/BF16/DistilBERT/super-resolution/OGA-LLM/VLM/RAG
(<https://ryzenai.docs.amd.com/en/latest/examples.md>); the RyzenAI-SW repo
tree (669 paths, `main`, fetched 2026-10-19) contains speech demos **only under
`Demos/ASR/{Whisper,Parakeet-TDT}` and `Transformer-examples/ASR/Whisper-AI`**
— no TTS directory. Serving TTS therefore means writing our own OGA host
(or driving `model_benchmark`-style C++ code) plus phonemizer + NeuCodec glue.
## 6. Two graphs on one NPU, and the iGPU hazard
* **Concurrency is a first-class driver feature.** The vendor `amdxdna` source
(in `xrt_plugin.2.25.260102.56`, 2026-06-29) sets `.hwctx_limit = 16` for
npu4/npu5 — i.e. **16 hardware contexts** on our device — and allocates each
context a set of AIE columns with QoS `opc = col_opc (4096) × num_col`
(`aie2_ctx.c`, `aie2_solver.h`), with `frame_boundary_preempt` /
`fill_preempt_slot` in `aie2_pci.h` (firmware preemption at frame boundaries).
So halogen's armed models and a TTS graph can hold separate contexts
simultaneously; they contend for columns and OPC share, they are not mutually
exclusive.
* AMD's user-visible history agrees: 1.4 "Support for up to **16 hardware
contexts** on Ryzen AI 300 series"; 1.5 "Application concurrency: improves the
resource distribution across applications"; 1.3 "Idle detection and suspension
of contexts", "Rebalance feature for AIE hardware resource optimization";
1.0 known issue "Support for multiple applications is limited to up to eight"
(all in <https://ryzenai.docs.amd.com/en/latest/relnotes.html>).
* **Package conflict, the real risk** [INFERENCE]: the vendor stack wants AMD's
XRT 2.25.37 + `xrt_plugin…amdxdna` deb **[host: distro `libxrt-npu2
1:2.21.75+dfsg-4` installed]**, and firmware must match the loaded `amdxdna.ko`
— the vendor README warns that a stale/mismatched `npu.sbin` causes
`ERT_CMD_ABORT`/mailbox timeouts, and that a distro **in-tree** `amdxdna` older
than the XRT SHIM makes `GET_ARRAY`/`QUERY_TELEMETRY` return
`EOPNOTSUPP`/`EINVAL` (<https://github.com/amd/xdna-driver> README,
fetched 2026-10-19). Installing AMD's debs over the distro XRT changes the ABI
under FastFlowLM/halogen, so the spike must decide the XRT version **once**, for
the whole host.
* **iGPU / fabric clock:** no vendor document supports a fabric-clock pin, and no
vendor document addresses NPU+iGPU concurrency hangs. AMD's Strix Halo
optimization doc (ROCm docs, dated 2026-02-20, and its successor "AMD RDNA3.5
system optimization", ROCm 10.1.0) covers GPUVM/GART/GTT, the TTM `pages_limit`
knob, `amd-ttm`, BIOS VRAM sizing, and minimum kernel versions
(<https://rocm.docs.amd.com/en/docs-7.2.0/how-to/system-optimization/strixhalo.html>,
<https://rocm.docs.amd.com/en/latest/reference/system-optimization/rdna3-5.html>).
The `pp_dpm_fclk` level-7 pin and the GPU+NPU hang observation stay
fleet-observed **[host]**, i.e. `[INFERENCE]` territory — no citation exists.
## 7. Paths I checked and ruled out (so nobody re-walks them)
* **Windows-only doors**: DirectML; Ryzen AI Windows EP; Lemonade's
`ryzenai-llm` and `whispercpp`-NPU engines (matrix above); AMD's OGA model
generation. Not usable on Dankclaw.
* **Mainline ONNX Runtime** has no AMD-NPU EP: its EP summary lists AMD ROCm and
AMD MIGraphX (GPU) and "Xilinx Vitis-AI (*preview*)" only
(<https://onnxruntime.ai/docs/execution-providers/>, 2026-10-19); the working
EP is AMD's own build (`libonnxruntime_providers_ryzenai.so` in the tarball's
deployment dir, per llm_linux).
* **ggml / llama.cpp / qwentts.cpp**: no XDNA backend → the current engine
(`tts-server` on GGUF, CPU-only build **[host]**) cannot be "turned on" for the
NPU; migration means a different runtime, not a flag.
* **`flm`**: catalog/engines are closed per-architecture (§2) — the cheapest door
by install cost, and it is not a door for TTS.
* **IRON / mlir-aie** is the only open toolchain that documents running on the
Ryzen AI NPU from Linux ("A close-to-metal Python API for programming AMD Ryzen™
AI NPUs, built on an open-source MLIR-based compiler toolchain"; "Getting
Started for AMD Ryzen™ AI on Linux", Ubuntu 24.04/24.10, XRT from
`ppa:amd-team/xrt`: `libxrt2 libxrt-npu2 … amdxdna-dkms`, `render` group
required) — <https://raw.githubusercontent.com/Xilinx/mlir-aie/main/README.md>,
fetched 2026-10-19. This is how FLM's kernels were made ("Low-level kernels
optimized using IRON + AIE-MLIR", FLM README) — i.e. real, but it is
hand-written per-op tile programming, not a model compiler: writing a TTS model
here is a multi-month engineering project, not a migration.
* **Embedded** Ryzen AI P100 support in the same Linux doc is irrelevant to STX.
## 8. Recommendation implied by the above (for Main's spike)
Spike the AMD path as decided, with these constraints planned in: Python 3.12 venv
+ 24.04-built wheels on Ubuntu 26.04; one host-wide XRT decision (AMD 2.25.37 vs
distro 2.21.75) with firmware/driver pairing checked via `xrt-smi examine` →
"NPU Strix Halo"; 7.8 GiB tarball staged off the public CDN URL (§3); pre-encode
each `reference.wav` with the **PyTorch** NeuCodec encoder because the ONNX codec
is decoder-only; keep phonemizer + codec on CPU; measure decode tokens/s against
the 50 Hz budget and peak RSS against the ~14 GiB headroom; expect to write the
serving shell yourself (AMD ships `model_benchmark`, no TTS demo).
## 9. Loose ends (not verified; I stopped on Main's stand-down)
* Contents of `ryzen_ai-1.8.0.tgz` (7.8 GiB) — whether the Linux tarball contains
the AIE-ML compiler (`vaiml`, `aiecompiler_client`) for the *BF16/INT8* flows
and which Python wheels it carries. My statement that non-LLM compilation works
on Linux rests on AMD's own Linux doc ("quicktest.py … compiles it and runs on
… NPU"), not on the package contents. Download was killed mid-flight.
* Whether AMD's `neutts` artifacts run correctly under the Linux `model_benchmark`
runner (the TTS rows are listed without OS qualifiers; no Linux TTS run is
documented anywhere in 1.8.0 docs).
* Exact AIE column count/total `ncols` exposed for Strix Halo (driver reads it
from AIE metadata: `ndev->total_col = min(XRS_MAX_COL, ndev->aie.metadata.cols)`).

# Qwen3-TTS payload + qwentts.cpp runtime: architecture and portability
Research deliverable (no code). Slice: *what the fleet's TTS payload actually is, and how
portable it is off the CPU ggml path.* Companion slice: `NpuRuntimeLandscape` (what NPU
runtimes exist on Dankclaw).
Evidence date: 2026-10-19. Everything below is grounded in:
- `github.com/ServeurpersoCom/qwentts.cpp` @ `5916bf7c79dbb4e66fc059cdc507a79a23a28bb4`
(2026-10-16, upstream HEAD on 2026-10-19) and its ggml submodule
`ServeurpersoCom/ggml` @ `cc5df49a6b878db2b68b9a7b45976e279594627d` (2026-10-16).
- The two GGUF files as they sit on Dankclaw (`/home/dank/models/Qwen3-TTS-GGUF/`), read
byte-for-byte from the live host.
- Upstream Qwen3-TTS model cards / release material.
Status: COMPLETE for the assigned slice. ANSWER C was confirmed on the live host the same
night — the running `frank-tts-engine` container carries `libggml-base.so.0.27.0` +
`libggml-cpu.so.0.27.0` and nothing else, and our own
`dankclaw/voiceservice/Containerfile.engine` writes `-DGGML_VULKAN=OFF` out explicitly, so
the iGPU change is a flag in a file the fleet owns. Verdict, measured contract and the NPU
exoneration chain: `tts-npu-spike-verdict-2026-10-19.md`.
---
## 1. What the payload is
Two files, both read byte-for-byte off the live host (`/home/dank/models/Qwen3-TTS-GGUF/`,
owned `dank:dank`, mtimes 2026-10-18 18:31), both from
`https://huggingface.co/Serveurperso/Qwen3-TTS-GGUF` (community converter, not Qwen):
| file | bytes | GGUF | tensors | arch string | file_type |
|---|---|---|---|---|---|
| `qwen-talker-1.7b-base-Q4_K_M.gguf` | 1,219,245,248 | v3, kv=64 | 480 | `qwen3-tts` | `Q4_K_M` |
| `qwen-tokenizer-12hz-Q8_0.gguf` | 291,150,624 | v3, kv=51 | 398 | `qwen3-tts-tokenizer` | `Q8_0` |
`general.name` of the talker file is `Qwen3-TTS-12Hz-1.7B-base`; the header sizes add up
to the file sizes (sum of tensor bytes + header + alignment padding), so nothing in these
files is unaccounted for.
### 1.1 Talker file (480 tensors)
Three models in one container, per `docs/ARCHITECTURE.md` §GGUF layout
(qwentts.cpp @ pinned commit) and confirmed by the tensor census:
| prefix | tensors | bytes | what it is |
|---|---|---|---|
| `talker.*` | 316 | 1,061.9 MB | 28-layer Qwen3 decoder (hidden 2048, FFN 6144, 16 Q heads / 8 KV heads, head_dim 128, RoPE θ=1e6, RMS ε=1e-6, ctx 32768), text stream + codec stream summed, `codec_head` → 3072 codebook-0 logits |
| `code_pred.*` | 88 | 114.8 MB | 5-layer Qwen3 MTP head (hidden 1024, FFN 3072, 15 acoustic codebooks × 2048), own KV cache |
| `spk_enc.*` | 76 | 36.6 MB | ECAPA-TDNN speaker encoder (x-vector, base checkpoints only; mel → conv0 → 3 SE-Res2Net → MFA → ASP → 2048-d vector) |
Dtype split (exact tensor byte sums): `q4_K` 250 tensors / 864.1 MB, `q6_K` 17 / 312.0 MB,
`f32` 176 / 25.8 MB, `f16` 37 / 11.4 MB.
Which tensors carry which quant is the load-bearing portability fact:
- `q6_K` (17): `talker.text_embd.weight [2048, 151936]` (255.3 MB), `talker.codec_embd.weight
[2048, 3072]`, and the 15 `code_pred.codec_embd.<g>.weight [2048, 2048]` embedding tables.
These are the llama.cpp `Q4_K_M` "embedding/output rows go to Q6_K" rule, applied to
embedding tables rather than to an `lm_head`.
- `q4_K` (250): every attention/FFN projection of the talker and of the code predictor.
Distinct matmul shapes: `[2048,2048]`×73, `[2048,1024]`×62, `[2048,6144]`×56,
`[6144,2048]`×28, `[1024,2048]`×20, `[1024,3072]`×10, `[1024,1024]`×10, `[3072,1024]`×5,
`[2048,3072]`×2, `[2048,151936]`×1. Every one is 2-D and ≥ 1024 on both axes — good
GEMM shapes, nothing exotic.
- `f32` (176) / `f16` (37): all of `spk_enc` (conv weights F16 because K=1/3/5 rows are not
block-alignable, per the converter's `should_quantize` policy in `tools/quantize.cpp` +
`quantize.sh`; every bias/norm/LayerScale vector F32), plus the talker/predictor norms and
the `text_proj` biases.
Metadata the runtime actually reads (talker file): `qwen3-tts.num_code_groups=16`,
`talker.vocab_size=3072`, `text_vocab_size=151936`, `text_hidden_size=2048`,
`position_id_per_seconds=13`, `rope.mrope_section=[24,20,20]`, `mrope_interleaved=1`,
the 7 codec special ids (pad 2148 / bos 2149 / eos 2150 / think 2154 / nothink 2155 /
think_bos 2156 / think_eos 2157), `language_names` (10: chinese, english, german, italian,
portuguese, spanish, japanese, korean, french, russian) with their codec ids, the text-side
special ids (im_start 151644, im_end 151645, tts_pad 151671, tts_bos 151672, tts_eos 151673),
the whole `generation_config.json` (do_sample, top_k 50, top_p 1.0, temperature 0.9,
repetition_penalty 1.05, `subtalker_*` mirrors, max_new_tokens 8192), and an embedded
**Qwen2 BPE tokenizer** (`tokenizer.ggml.model=gpt2`, 151,676 tokens, 151,291 merges,
eos 151643) — that BPE block is 5.95 MB of the header, i.e. 49 % of the header is vocabulary.
Two live-file details that contradict the upstream doc text (worth knowing when reading
`docs/ARCHITECTURE.md`: the doc example block is stale against the shipped file):
`mrope_interleaved` is **1** (doc shows `false`), and `spk_enc.sample_rate` is **24000**
(doc says 16000). Doc also says "404 tensors on the 1.7B voice_design build" — the base
build shipped here has 480 because it carries `spk_enc.*`.
### 1.2 Tokenizer/codec file (398 tensors)
One neural audio codec, 12.5 frames/s over 24 kHz mono, hop 1920, 16 codebooks × 2048
entries (1 semantic + 15 acoustic). Dtype split: `f16` 50 / 143.6 MB, `q8_0` 110 / 76.9 MB,
`f32` 238 / 70.7 MB. `tok_dec.*` 253 tensors / 201.3 MB, `tok_enc.*` 145 / 89.9 MB.
Composition (metadata + tensor census, both files agree):
- **Encoder** (used only to make voice references, not on the synthesis hot path): SEANet
conv stack (init k=7, 4 stages with ratios 8/6/5/4 → cumulative 960×, 64→512 ch, final
k=3), an 8-layer transformer (hidden 512, 8 heads, head_dim 64, FFN 2048, RoPE 1e4,
LayerNorm+bias, GELU, LayerScale), a downsample conv k=4 s=2 (25 → 12.5 Hz), then the RVQ
argmin loop. Metadata records `encoder.num_quantizers=32` with
`encoder_valid_num_quantizers=16` — 16 codebooks are used, 16 are dead weight carried from
the upstream config.
- **Decoder** (the hot path: every generated frame): 16 codebook lookups + per-split
`output_proj` (256→512), `conv_pre`, an 8-layer transformer (hidden 512, 16/16 heads,
head_dim 64, FFN 1024, **sliding window 72**, RMSNorm, SwiGLU, LayerScale, input_proj
1024→512 / output_proj 512→1024), a ConvNeXt upampler (`upsampling_ratios=[2,2]`, causal
transposed convs + depthwise k=7), then a DAC-style decoder `dec.0..3`
(`upsample_rates=[8,5,4,3]`, channels 1536→768→384→192→96, `decoder_dim=1536`) whose blocks
are SnakeBeta → causal transposed conv (k = 2·stride) → 3 residual units (dilations 1/3/9)
→ snake_post → conv_post k=7 → 96→1.
- All 32 codebook tensors are **F32, 67.1 MB total** (16 encode + 16 decode, `[256, 2048]`),
deliberately unquantized: the converter's `should_quantize` keeps RVQ codebooks and their
wrapping projections at F32 because nearest-neighbour lookup is sensitive to per-row
quantisation noise (`docs/ARCHITECTURE.md` "Quantisation policy"; mirrored in
`quantize.sh`). 49 of the codec's 55 3-D conv tensors are **F16** with non-alignable K
(7, 3, 2, 1, 16, 10, …) — they cannot be block-quantized at all.
- **No flow matching, no diffusion, no vocoder-with-ODE.** It is a pure RVQ codec
(Mimi/SoundStream/Mimi-style: SEANet + transformer + DAC decoder). That matters for the
NPU question: every component is convolution, attention, or embedding lookup.
### 1.3 Where the payload came from, and what the official weights look like
Official upstream (`huggingface.co/api/models`, retrieved 2026-10-19):
| repo | last modified | license | weights |
|---|---|---|---|
| `Qwen/Qwen3-TTS-12Hz-1.7B-Base` | 2026-01-23 | apache-2.0 | `model.safetensors` BF16, 1,928,677,440 params, plus an embedded `speech_tokenizer/model.safetensors` |
| `Qwen/Qwen3-TTS-12Hz-1.7B-CustomVoice` | 2026-01-29 | apache-2.0 | same layout, named-speaker tables |
| `Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign` | 2026-01-29 | apache-2.0 | 1.7B only |
| `Qwen/Qwen3-TTS-12Hz-0.6B-Base` / `-0.6B-CustomVoice` | 2026-01-29 | apache-2.0 | narrow variant (hidden 1024) |
| `Qwen/Qwen3-TTS-Tokenizer-12Hz` | 2026-01-29 | apache-2.0 | codec alone, F32, 170,557,441 params |
So the GGUF is **not** the only public form: the safetensors are the canonical form
(Apache-2.0, no separate community license risk), and the GGUF is a lossy re-quantization of
them produced by the same author who wrote the runtime (`Serveurperso`), via
`checkpoints.sh` → `convert.py` (F32 GGUF) → `quantize.sh` (BF16/Q8_0/Q4_K_M).
Sizes to remember for any re-export: the talker container is 1.93 B params in BF16
(that count includes the embedded codec), the codec alone is 170.6 M params in F32.
**Portability consequence #1 — the GGUF is a dead end off-ggml.** Q4_K/Q6_K are ggml
block formats (256-element super-blocks, F16 sub-block scales, 144 B / 210 B per block). No
ONNX graph, no Vitis-AI/AIE-ML compiler, and no vendor NPU runtime consumes them; AMD's own
quantizer works from ONNX (`ryzenai-quantize`, QDQ/QOP power-of-two — Ryzen AI Software
1.8.0 release notes, https://ryzenai.docs.amd.com/en/latest/relnotes.html). Moving the
payload to a non-ggml stack therefore means starting from the safetensors again, not
converting the GGUF.
**Portability consequence #2 — the quantization split is semantic, not cosmetic.** The
converter keeps RVQ codebooks, `input_proj`/`output_proj` around them, and every 1-D and
non-alignable-conv tensor out of the k-quants precisely because quantizing them breaks voice
fidelity. Any re-quantization path (GPTQ/AWQ/QDQ-INT8/INT4 for an NPU compiler) inherits that
constraint: the talker backbone is requantizable, the codec's codebook lookups and SnakeBeta
convs are not, at least not without re-measuring voice quality.
## 2. What the runtime is
`qwentts.cpp` @ `5916bf7c` (2026-10-16, MIT; upstream model Apache-2.0) is a C++17 ggml
application — 43 files under `src/` + `tools/`, three binaries (`qwen-tts`, `qwen-codec`,
`tts-server`) over one public plain-C99 ABI (`src/qwen.h`, `qt_*`, `QT_ABI_VERSION`
range-checked; `tests/abi-c.c` is compiled `-std=c99 -Wall -Werror -pedantic` on every
build). It is not a llama.cpp derivative: it links ggml directly and builds its own graphs.
Five graph families, and their shapes are the whole portability story:
| graph | batch/time axis | notes |
|---|---|---|
| talker prefill | T = prompt length (hundreds–thousands) | summed text+codec embedding streams, 28-layer GQA decoder, KV cache |
| talker decode | **T = 1 per audio frame** | 12.5 frames/s → 80 ms of audio per step; `codec_head` → 3072 logits |
| code predictor (MTP) | **T = 1, 16 steps per frame** (2 prefill + 14 decode, cache reset every frame) | 5-layer decoder, 15 heads × 2048 |
| speaker encoder | one pass per voice registration | ECAPA-TDNN with mel fused into the graph |
| codec decode | offline: T = 300-frame chunks; streaming: **T = 1 frame** with persistent conv/KV-ring state | the streaming graph is built once with fixed topology so the CUDA graph cache stays in pure replay |
Per generated frame the host therefore runs ~1 + 16 + 1 tiny graph computes for 80 ms of
audio, and `tts-server` serializes synthesis FIFO (`--max-batch` defaults to 1, and the
fleet runs it at 1). This is the archetypal latency-bound, bandwidth-bound,
batch-1 workload; the only big-M matmuls in the whole system are the prefill and the
chunked (buffered) codec decode.
Op contract actually issued to ggml (`src/`, counted): `mul_mat` 77, `cont` 70, `add` 57,
`mul` 40, `rms_norm` 22, `clamp` 15, `rope_ext` 12, `get_rows` 12, `set_rows` 8,
`scale_bias` 6, `swiglu_split` 5, `sqr` 5, `mean` 5, `elu` 4, `col2im_1d` 4, `soft_max` 3,
`conv_1d` 3, `im2col` 2, `cumsum` 2, `sin`, `sigmoid`, `tanh`, `div`, `argsort`, `transpose`,
`permute`, `reshape/view`, plus the CPU-side Philox multinomial sampler.
**No custom ggml op is required today.** The repo doc still says the fork "provides the two
custom ops the codec needs: `GGML_OP_SNAKE` and `GGML_OP_COL2IM_1D`"; that is stale at the
pinned commit. Verified 2026-10-19:
- the submodule `ServeurpersoCom/ggml` @ `cc5df49` is upstream `ggml-org/ggml` master
(`a05c992`, 2026-10-15) **+2 commits, 0 behind** (GitHub compare API), and
`include/ggml.h` is byte-identical to upstream master (`diff` empty);
- the 2 commits are `193e339` (2026-06-19) "cpu: add fused snake activation
(mul -> sin -> sqr -> mul -> add)" — a **CPU subgraph fusion**, not an op (the runtime
builds snake with `ggml_sin`/`ggml_sqr`/`ggml_mul`/`ggml_add` in `src/dac-decoder-v2.h:222`),
and `cc5df49` "sycl: fix get_rows on reordered quantized weights";
- `ggml_col2im_1d` is an **upstream ggml API** (same declaration, line 2097, in both trees);
the Vulkan backend fuses the snake chain through ggml's generic subgraph fuser
(`ggml-vulkan.cpp:14548 ggml_vk_can_fuse_snake`, `vulkan-shaders/snake.comp`).
Consequence: any stock ggml build (upstream, or llama.cpp's vendored ggml) can execute this
payload; only the CPU snake fusion is fork-specific, and it is a performance nicety.
Backend/device support: every tool takes `--device <name>` (`CUDA0`, `Vulkan0`, `MTL0`,
`CPU…`, default best available), resolved through the ggml backend registry; the deployed
container turns CUDA/HIP/Vulkan/Metal/SYCL/RPC/BLAS all OFF and compiles the native-CPU
backend with OpenMP, with CPU threads = `hardware_concurrency()/2` (`src/backend.h`).
The registry in this ggml knows CPU, CUDA, Metal, SYCL, Vulkan, WebGPU, ZDNN, OpenCL,
**Hexagon**, BLAS, RPC, VirtGPU, **CANN**, ZenDNN, **OpenVINO**, ET — and nothing AMD-NPU
(no `xdna`/`aie`/`vitis`/`ryzen` string anywhere in the ggml tree).
Voice handling (what the fleet depends on): the registry is **process RAM only**; a restart
empties it, which is why the unit has a boot warmer. `POST /v1/audio/voices` accepts either
`{name, ref_text, wav_b64}` (server extracts) or `{name, ref_text, spk_b64, rvq_b64}`
(pre-extracted latents verbatim); `ref_text` present ⇒ ICL clone mode, absent ⇒ x-vector-only
mode. `.spk` = the ECAPA x-vector; `.rvq` = 16 codes/frame packed 11 bits LSB-first
(`src/rvq-file.h`). `wav` and `pcm` `response_format` are different audio at the same seed
(buffered chunked decode vs stateful streaming decode) — the fleet already encodes that rule.
Parity expectations for any port: the upstream harness matches the PyTorch reference per
stage (embed cos 0.999988, all 28 hidden taps ≥ 0.999893, logits 0.999824) but explicitly
reports free-run divergence (`CodesFull exact 4.96 %`, `Audio cos 0.095`) and explains why —
one argmax tie at FP epsilon diverts the AR trajectory. So a migrated endpoint must be
accepted by listening + per-stage cosine, never by waveform diff against today's audio.

## 3. The three answers Main asked for
### ANSWER A — Qwen3-TTS GGUF → ONNX: no, and it does not matter
There is **no GGUF→ONNX path** and there will not be a useful one: GGUF is a weight
container for ggml, its Q4_K/Q6_K block layouts have no ONNX consumer, and nothing in the
GGUF carries the *graph* (the talker/predictor/codec structure lives in C++ code, only the
op-level structure exists in ggml at runtime). But the GGUF is not the payload's only form —
official Apache-2.0 safetensors are upstream, and **four independent ports of the full
pipeline already exist**:
| port | form | what it proves |
|---|---|---|
| `xkos/Qwen3-TTS-12Hz-1.7B-ONNX` (HF, updated 2026-03-03, apache-2.0) | FP16+FP32 ONNX, fp16/voice_clone + fp16/voice_design splits: `talker_decode.onnx`, `code_predictor.onnx`, `code_predictor_kv.onnx`, `code_predictor_embed_g0..15.onnx`, `text_embedding.onnx`, `codec_embedding.onnx`, shared `speaker_encoder.onnx`, `speech_tokenizer_encoder.onnx`, `speech_tokenizer_decoder.onnx`, `model_cache.npz` | every component of this architecture exports to ONNX, codec decoder included |
| `zhangluoyang/qwen3-tts-onnxruntime` | export tooling + Python inference for Base/CustomVoice/VoiceDesign | the export is reproducible from the official checkpoints |
| `Echo9Zulu/Qwen3-TTS-12Hz-CustomVoice-1.7B-INT8-OpenVINO`, `aurora2035/Qwen3-TTS-12Hz-0.6B-Base-OpenVINO-INT8` (2026-03) | OpenVINO IR, **INT8**: `talker`, `code_predictor`, `codec_embedding`, `text_model`, `openvino_speaker_encoder_model`, `speech_tokenizer/speech_decoder` | the talker and predictor INT8-quantize for an NPU-targeting stack |
| `litert-community/Qwen3-TTS-12Hz-0.6B-Base` (2026-10-17, apache-2.0) | `qwen3_tts_int8.litertlm` / `_int4.litertlm` (LiteRT-LM `OmniEngine`), legacy split graphs `talker_int4.tflite` (prefill_32/prefill_128/decode signatures, KV 1024, blockwise-32 OCTAV INT4), `mtp_folded_int8.tflite` (16 inner steps × 5 layers folded into one graph, in-graph argmax+gather, GPTQ int8, ~5× faster), `codec_partA` (transformer, fp32) + `codec_partB` (conv upsampler, XNNPACK FORCE_FP16, ~2.5×, "ASR-identical") | an NPU/mobile compiler accepts the whole thing — at the price of graph splitting, static prefill buckets, and folding the per-frame inner loop |
What the ports had to concede, and what any port inherits:
- the generation structure does not fit existing engine loops: LiteRT-LM's Engine "does not
support this generation structure yet", so their first shape was **three graphs + a
host-side loop**, and the MTP step was "invoked 17× per frame" until they folded it;
- per-step dispatch cost dominates: even on a Snapdragon 8 Elite Gen 5 they keep the MTP
loop, text projection, embedding gathers and the codec on CPU "avoiding 16 synchronous
CPU↔GPU round-trips per 80 ms frame", putting only the 28-layer talker on the GPU;
- RTF on that hardware is **2.57–2.97 (Galaxy S26) and 5.65–8.48 (Pixel 10 Pro)** for the
0.6 B model, i.e. 2.6–8× slower than real time. Dankclaw's current CPU engine measures
**warm RTF 0.55–0.67 with TTFA 94–112 ms** on the 1.7 B model (fleet trial, 2026-10-18).
An NPU port is not "faster by default" for this workload; it has to beat that.
- quantize the LM (int8/int4: proven), keep the codec's codebook lookups and SnakeBeta convs
in fp16/fp32 (the LiteRT split does exactly this).
So: the answer to "can the fleet's payload be exported" is *yes — from the safetensors, not
from the GGUF*, and the work is a pipeline rewrite (multi-graph host loop, per-frame fold,
static prefill buckets), not a conversion. That is the same conclusion NeuTTS-Air's
precompiled-graph route encodes: on AMD's Linux stack the graph is vendor-curated, so the
fleet chooses the model that AMD already compiled rather than compiling Qwen3-TTS.
### ANSWER B — is there any ggml backend for an AMD NPU? Not upstream; three out-of-tree, none for TTS
Checked against the trees today (2026-10-19), because this was the crux:
- **Nothing in-tree.** `ggml-org/llama.cpp` master (4,237 paths, GitHub tree API) contains no
`xdna`/`aie`/`vitis`/`ryzen` file or directory; the ggml backend set is CPU, BLAS, CUDA,
HIP, Metal, Vulkan, SYCL, OpenCL, WebGPU, MUSA, RPC, CANN (Ascend), **Hexagon** (Qualcomm),
OpenVINO (Intel CPU/GPU/NPU), ZenDNN, ZDNN, VirtGPU, ET. The deployed fork's registry
matches. The feature request "Feature Request: XDNA backend" (llama.cpp issue **#21725**,
opened 2026-04-10) is still **open**, 34 comments; the older #1499 was closed stale
2025-04-07. So Main's premise is confirmed: no ggml XDNA backend exists to flip a flag on.
- **`Cyronius/ggml-xdna`** — a real ggml backend (`XDNA0`) loaded into *stock* llama.cpp via
`GGML_BACKEND_PATH`, no fork. It does bfp16 (8-value blocks sharing an exponent) GEMMs from
GGUF weights, and is **prefill-only**: it takes only matmuls in prompt chunks ≥ 1024 tokens
(`GGML_XDNA_MIN_BATCH` default 1024, `GGML_XDNA_MIN_MFLOP` 256), attention and every decode
token stay on the Vulkan device; pinned to llama.cpp release b10944; tested on Strix Point
(HX 370) only — Strix Halo "should pass, but nobody has run it on one yet"; Linux support
new and untested on hardware by the author; needs `libxrt-npu2`, `/dev/accel/accel0`,
unlimited `memlock`. Best measured prefill gain 1.88× on a 27 B model; models under
2,048-wide **lose** (0.77× at width 1,536).
- **`BrandedTamarasu-glitch/OllamaAMDNPU`** — a llama.cpp fork with `-DGGML_XDNA=ON`,
explicitly targeting **Ryzen AI MAX / XDNA2 on Linux** (`/dev/accel/accel0`, XRT 2.21.75+,
amdxdna, unlimited memlock). It implements **only `GGML_OP_MUL_MAT`**, dispatched to
mlir-aie-compiled `.xclbin`s built per fixed tile shape (e.g. `M=2048 K=2048 N=64`,
int8 in / int32 out, per-row weight scales cached at first use), with a second slot for a
different K. Its own numbers on a Ryzen AI MAX 385 with Llama-3.1-8B Q4_K_M: NPU prefill
12–19 t/s vs **Vulkan iGPU 600–930 t/s**, NPU decode **0.65–1.40 t/s** ("Decode does not
use the NPU … M=1 per token, no xclbin covers it"), 0.6 % AIE utilization, and the stated
conclusion "**For LLaMA 8B on Strix Halo: use Vulkan exclusively**". Single-maintainer,
AI-assisted, self-measured — treat as a proof of concept, but it is the closest published
picture of what XDNA2 graph execution costs.
- Also referenced in the same thread: `Atomic-Germ/OpenFlowLM-Next` (whole-model NPU engine,
LLM-only — and slower than the iGPU in the same comparison), `GaTmaNnes/xdna2-`,
`hardWorker254/Npu-Embeddings-XDNA1` (adds Whisper ASR ops, NPU1/Linux). None is a TTS path.
Why none of them would carry this workload even if installed: the TTS hot loop is **batch-1
by construction** (one talker step + 16 predictor steps + one codec frame per 80 ms), which
sits under every dispatch gate those backends define (≥1024 tokens / ≥32768 M·N·K / tile M
covering only prefill), and the codec half of the pipeline is conv, col2im, gather and
elementwise ops — not `MUL_MAT` — so it would fall back to CPU op-by-op. The NPU case for
this host is therefore *not* "run Qwen3-TTS on the NPU"; it is "run a vendor-compiled AR TTS
graph on the NPU", which is exactly the NeuTTS-Air spike.
### ANSWER C — would `qwentts.cpp` build for the gfx1151 iGPU? Yes, via **Vulkan**, not HIP
- Upstream ships the build scripts and claims the backends: `buildvulkan.sh` ("AMD/Intel GPU
(Vulkan)"), `buildcuda.sh`, `buildsycl.sh`, `buildcpu.sh`, `buildall.sh` (all backends,
runtime dynamic loading), and README line 6 "runs on CPU, CUDA, Metal, Vulkan". CMake knobs
`GGML_VULKAN` / `GGML_HIP` / `GGML_SYCL` are the same ones the fleet's Containerfile turns
OFF, so the engine rebuild is a flag change: `-DGGML_VULKAN=ON` plus
`--device Vulkan0` on the same command line the unit runs today.
- The codec's exotic ops are covered by the Vulkan backend, which is the thing that decides
whether a GPU build is coherent: `vulkan-shaders/col2im_1d.comp`, `snake.comp`,
`swiglu*.comp`, `cumsum*.comp` exist and `supports_op` handles `GGML_OP_COL2IM_1D` /
`CONV_TRANSPOSE_1D` / `CUMSUM`. By contrast `COL2IM_1D` appears in **no** HIP, OpenCL,
WebGPU, Hexagon or CANN source — a **HIP** (ROCm) build would shard the ConvNeXt/DAC
transposed convs back to the CPU per op. On an AMD iGPU the portable path is RADV/Vulkan.
- `--device` also accepts a multi-device split (`-dev`-style naming is ggml's), and the
runtime's documented FP16 guard (`--clamp-fp16`) exists for sub-Ampere CUDA accumulation;
nothing in the tree is NVIDIA-specific.
- Unverified by me: any vendor statement pairing this fork with gfx1151. Supporting evidence
that the hardware/driver combination is viable: this very host already runs a Vulkan
endpoint on the gfx1151 iGPU (fleet ground truth, 2026-10-19), and Mesa's Vulkan
implementation is officially supported on Radeon Software for Linux
(AMD release notes RN-AMDGPU-UNIFIED-LINUX-25.20.3). A gfx1151 Vulkan build of this fork is
a build-and-measure spike, not an unsupported port.
- The real constraint is the one already in the fleet docs: the iGPU belongs to another
endpoint, and GPU+NPU concurrency has hung Strix Halo machines. An iGPU TTS build competes
with the text endpoints for the same silicon; the NPU route's only genuine advantage is
that it does not (the XDNA backend authors make the same argument: "Use NPU when the iGPU
is busy … no GPU contention").

## 4. What any replacement must reproduce, and what the voices cost
Endpoint contract in production today (from the live unit/env, not the doc):
`tts-server --model qwen-talker-1.7b-base-Q4_K_M.gguf --codec qwen-tokenizer-12hz-Q8_0.gguf
--alias frank-tts-engine --host 0.0.0.0 --port 8880 --lang auto --max-batch 1`, no published
port (the façade on :7772 dials the private bridge name), `GET /health`, `GET /v1/models`,
`GET|POST /v1/audio/voices`, `DELETE /v1/audio/voices/{name}`, `POST /v1/audio/speech` with
`response_format` wav|pcm (different audio at equal seed) and optional `seed`,
`max_new_tokens`, `temperature`, `top_k`, `top_p`, `repetition_penalty`, `subtalker_*`.
Voice registry is RAM-only, so boot warming is mandatory, and `--alias` keeps the quantization
choice out of every consumer's config.
Live voice census on Dankclaw (2026-10-19, `/home/dank/voices/`): three packs
(`narrator1..3`), each carrying `reference.wav` (24 kHz mono crop), `reference16k.wav`,
`manifest.json` (keys: name, kind, generated_utc, pipeline, source, forbidden_region_guard,
silence_scan, crop, loudnorm, audio, acceptance, acceptance_passed) and ffmpeg analysis
artifacts. **No `.spk` and no `.rvq` exist on the live host** — the repo's
`build-voice-pack.sh` treats them as required-but-they-are-not-there, so today the engine
re-extracts the x-vector (and the ICL codes when a transcript is supplied) from the WAV at
registration time.
That is the portable part, and it is the same shape AMD's NeuTTS flow wants
(`encode_reference(reference.wav)` + a reference transcript): the fleet's voice identity is
*the WAV plus its transcript*, processed at request/registration time by the model's own
speaker encoder + codec — **never a trained per-voice artifact**. Qwen3-TTS cloning is
inference-time conditioning (`generate_voice_clone(ref_audio=…, ref_text=…, x_vector_only_mode=…)`;
`create_voice_clone_prompt` exists purely to avoid recomputing prompt features). So any
replacement that consumes a WAV (+transcript) keeps all three narrators alive with no
re-derivation, and if it wants precomputed latents instead, the LiteRT precedent shows what
that looks like: a 4 KB x-vector `.npy` per voice, extracted offline
(`extract_speaker_embedding.py`) — for the 1.7 B base checkpoint that vector is 2048-dim
(`qwen3-tts.spk_enc.embedding_length = 2048` in the shipped GGUF; the LiteRT 0.6 B bundle
ships a 1024-dim one).
One trap for a mixed-runtime future: `.spk`/`.rvq` files, if they are ever written, are
engine-specific encodings (ECAPA x-vector layout; 11-bit-packed RVQ stream) and are **not**
interchangeable between runtimes. Keep `reference.wav` as the pack's source of truth and
regenerate anything derived per engine — which is what the NeuTTS re-clone plan does anyway.

# TTS on the Strix Halo NPU — spike verdict (2026-10-19)
Question: **how can the fleet's TTS engine run on hardware rather than CPU?** Answer in
one line: not on the NPU — the loader, not the silicon, refuses it; the door that exists is
the gfx1151 iGPU behind a build flag we already own.
Spike evidence lives in `report/npu-tts-runtime-landscape-2026-10-19.md` (which runtimes can
reach XDNA2 at all) and `report/qwen3-tts-payload-portability-2026-10-19.md` (what the
payload is and where it can be moved). This page owns only the **measured spike result** and
the **model-side contract** neither slice has. Throwaway work ran in containers under
`/home/dank/spikes/npu-tts` on Dankclaw; nothing in the fleet was changed — `frank-tts` and
`frank-tts-engine` still serve `narrator1|2|3` on CPU.
Legend: **[host]** live census 2026-10-19 · **[spike]** measured in the spike containers ·
**[vendor]** primary vendor source, with the version it holds for.
## 1. Verdict
**NO-GO on the NPU, and the wall is a loader.** The XDNA2 device is healthy by AMD's own
instruments; the runtime that owns this model family opens the device and then declines the
graph, silently. One run loaded successfully; byte-identical runs never reproduced it, and a
path that cannot be reproduced is not a foundation. **[spike]**
**Go on the iGPU, and the lever is in this repo.**
`dankclaw/voiceservice/Containerfile.engine` builds `qwentts.cpp` (commit `5916bf7`) with
`-DGGML_VULKAN=OFF` written out deliberately beside CUDA/HIP/METAL/SYCL/RPC — the running
container carries `libggml-base.so.0.27.0` + `libggml-cpu.so.0.27.0` + `tts-server` and
nothing else. So: `-DGGML_VULKAN=ON` + `--device Vulkan0`, plus `/dev/dri` passthrough in
the engine quadlet (the ComfyUI pattern: `AddDevice` + `GroupAdd=keep-groups` + a
world-writable udev rule). The target shape is **co-tenancy** — the engine resident on the
gfx1151 *beside* `frank-dragoon`, not a handover. §5 carries the census and both gates:
the **heap gate is PASSED** — RADV's `DEVICE_LOCAL` heap is 77.33 GiB with 65.16 GiB of
budget while dragoon is loaded, so memory is not the constraint — which leaves the
contention gate (dragoon's TTFT with a synthesis in flight) and one unproven piece:
whether qwentts.cpp's codec ops have Vulkan kernels for every op. **[host]** **[spike]**
Why the iGPU is worth doing at all, given CPU already works: the deployed payload needs
only **12.5 codes/s** (§2), so this is latency headroom and freed cores, not reviving a
dead service. The independent Strix Halo measurement in the portability slice ("use Vulkan
exclusively"; NPU decode under 1.5 t/s for an 8B) points the same way.
## 2. The two arms do not share a real-time bar
|Arm|Talker|Codec|Codes per second of audio|Bar|
|---|---|---|---|---|
|**Deployed** (`frank-tts-engine`)|`qwen-talker-1.7b-base-Q4_K_M.gguf`|`qwen-tokenizer-12hz-Q8_0.gguf`|**12.5**|~13 tok/s **[host]**|
|**Spike** (`amd/neutts-air_rai_1.8.0_npu_4K`)|NuTTS-Air, 24-layer Qwen2|NeuCodec `24000 / hop 480`|**50.00**|~50 tok/s **[spike]**|
Measured from the staged NPU artifact — the contract any future arm must satisfy:
|Fact|Value|
|---|---|
Vocab|`genai_config.json` `vocab_size` **217,652**; base BPE 151,643; specials 151,644–151,670 **[spike]**|
Speech tokens|**65,536** `<|speech_N|>` entries, ids **151,671–217,206** contiguous; the vendor template maps a codec index straight to its id, `"".join(f"<|speech_{i}|>")`. A 10,001-code assumption silently truncates the space — encoded references really do reach the 60k range. **[spike]**|
Stop token|`<|SPEECH_GENERATION_END|>` = 151,670, but the export's `model.eos_token_id` is `[151645, 151643]` (the *chat turn* stop) and `search.eos_token_ids` is unset — pass 151,670 explicitly or speech ends after one token **[spike]**|
Input ceiling|4096 tokens **total**, input + output **[vendor]**|
Frame rate|50.00 codes/s confirmed across three references (49.96 / 49.99 / 50.00) **[spike]**|
Reference encode|`librosa.load(sr=16000, mono=True)` → `[1,1,T]` float → `codec.encode_code(audio_or_path=…)` (vendor `NeuTTS.encode_reference`); CPU RTF 0.28–0.38 on 8 threads, so codes are a cacheable one-time cost, never a per-request charge. `neucodec` also needs `torchtune`; install both `--no-deps --target <dir>` so a second torch never shadows the venv's. **[spike]**|
Pre-encoded voices|`/spike/logs/codes-narrator{1,2,3}.npy` — 994 / 1,249 / 1,250 codes for 19.90 / 24.98 / 25.00 s **[spike]**|
**Gap that any arm inherits:** the voice packs carry no transcript. `manifest.json` holds
provenance and crop geometry (`crop.source_speech_run` 98.739–118.636 s of a 22,569 s
audiobook) and no text, and Dankclaw has no ASR at all — `whisper`, `whisper.cpp`,
`faster-whisper` all absent. NuTTS conditioning needs `ref_text`; do not invent it. **[host]**
## 3. Exoneration chain — why the blame is not the hardware
Every row is an instrument, not an inference.
|Probe|Result|
|---|---|
`xrt-smi examine`|`[0000:c6:00.1] RyzenAI-npu5 aie2p 6x8`, XRT 2.25.37 (vendor extract), NPU fw 1.1.2.65, `amdxdna 7.0.0-38-generic` **[spike]**|
`xrt-smi validate`|**PASSED**, including `throughput` **[spike]**|
`pyxrt.device(0)` in-container|constructs — XRT enumerates the device **[spike]**|
`strace -f -e trace=openat` on the failing load|`genai_config.json` read → `model.onnx` opened → `libxrt_driver_xdna.so.2` loaded → `/dev/accel/accel0` opened `O_RDWR` → GEM ioctls succeed → **EP declines, before touching `dd_metastate_*` or `cache/txn_bins.zip`** **[spike]**|
`dmesg`, `fuser /dev/accel/accel0`|silent since boot, no holder — the decline never reaches the kernel **[spike]**|
Hardlinked mirror dirs of the model tree (`rundir*`)|retired, no change — the "metastate shadowing" theory is dead **[spike]**|
Every logging lever in that build: `GENAI_ORT_VERBOSE_LOGGING`, `GENAI_LOG_ORT_LIB`, `set_log_options`, `set_log_callback(callable)`, `RYZENAI_EP_TRACING`, `RYZENAI_LLM_PROFILE_INIT`|**zero lines** — the decline path is silent **[spike]**|
Vendor `quicktest`|`Session successfully initialized` — proves the XRT/driver/device path, **not** NPU residency: that build falls back to CPU silently. Prove residency with `/sys/class/accel/accel0/device/mem_usage` during generation. **[spike] [vendor]**|
No NPU token rate was ever measured, so none is quoted here. The single successful load
(13:17, `[load] 0.84s`, finite logits, XRT banner at *generate* time) has not been
reproduced by the byte-identical command since, with the model files pristine by inode and
mtime. **[spike]**
## 4. Host gates the spike proved (so they are not re-litigated)
- **Rootless containers cannot read `/dev/accel/accel0`** (`root:render` 0660): the host
gid never enters the userns map. `--group-add keep-groups`, `--userns=keep-id`,
`--userns=keep-id:gid=990`, `--group-add render`, `--group-add gid:990` — all fail.
Doors: rootful podman (separate storage), or a world-writable udev rule, which the fleet
already does for `kfd`/`renderD*`. **[spike]**
- **Never `dpkg -i` the vendor XRT deb** — it installs a DKMS `amdxdna` over the distro
driver. `dpkg-deb -x` the debs and bind-mount the tree at `/opt/xilinx/xrt`; the plugin
deb is what carries `libxrt_driver_xdna.so`. **[spike]**
- In-tree `amdxdna 0.7.0-38` + `iommu=pt` is enough for context creation; a missing device
node is *not* the modern failure mode. **[host]**
- `xrt-smi` inside a container needs `libboost-filesystem1.83.0` +
`libboost-program-options1.83.0` (**hyphenated** Ubuntu names, after `apt update`);
boost is needed by `xrt-smi` only, never by the OGA/EP path. **[spike]**
- Headroom is tight and it is host RAM, not a separate pool — see §5 for tonight's census.
A multi-GB NPU partition plus an AIE compile workspace does not fit beside
`frank-dragoon`. Benign-looking `Failed to alloc dev bo memory, ret -28` is that
pressure. **[host]**
## 5. Target shape: the TTS engine shares the gfx1151 with `frank-dragoon`
The deployment Frank wants is **both resident at once**, not a handover. Measured 2026-10-19
(read-only, nothing loaded or unloaded):
|Measure|Value|Reading|
|---|---|---|
iGPU GTT in use|**18,523 MiB of 116,733 MiB**|≈96 GiB of aperture free; this is the real budget (fleet law) **[host]**|
DRM "VRAM" carve-out|2,048 MiB total, 174 MiB used|what KFD/DRM calls dedicated — **not** the budget **[host]**|
Host RAM|121 GiB total, 17 GiB available, 79 GiB buff/cache|**GTT pages are system pages**: an iGPU allocation is host RAM consumed, so the two tenants share one pool **[host]**|
TTS engine today|3.84 GiB RSS, CPU|its device-resident replacement lands in that same pool **[host]**|
**Two gates, in this order.**
1. **Heap gate — PASSED.** RADV does **not** hand a container tenant the 2 GiB DRM
carve-out. `vulkaninfo` inside the engine's own base image (`ubuntu:24.04` plus
`mesa-vulkan-drivers vulkan-tools`, `--device /dev/dri`, rootless) sees
`Radeon 8060S Graphics (RADV GFX1151)`, driver `radv`, API 1.4.318, and reports:
|Heap|size|budget with dragoon loaded|flags|
|---|---|---|---|
|0|38.67 GiB|32.58 GiB|host-visible, not device-local|
|1|**77.33 GiB**|**65.16 GiB**|`DEVICE_LOCAL`|
The heaps sum to the ~116 GiB aperture in Mesa's ⅓/⅔ APU split — the same RAM twice:
a Vulkan allocation is a GTT mapping, so a budget is a ceiling on mappings, not a pile
of free silicon memory. ggml's Vulkan backend asks for `DEVICE_LOCAL`, which is heap 1,
and the TTS engine needs roughly 4 GiB of it. **Memory stops being the question.** **[spike]**
Probe traps: `vulkaninfo --batch` is not a flag in this `vulkan-tools` (it prints the
help page and exits 1 — use `vulkaninfo --text`), and the container has **no NVIDIA
ICD**, so Vulkan device 0 is the iGPU here. Do not trust that ordering — select by
device *name*, or an image that grows an `nvidia_icd.json` silently points TTS at the
3090 slot.
2. **Contention gate.** `frank-dragoon` is the endpoint the operator session runs on, so the
honest measurement with both loaded is dragoon's own TTFT and decode with a synthesis in
flight — one request each, no ladder. Expect compute-unit sharing rather than memory
pressure: the aperture has room, the shaders do not.
**Change surface** — the whole edit, so nobody re-derives it:
1. `Containerfile.engine` build stage: add `libvulkan-dev glslang-dev`. It installs only
`ca-certificates cmake g++ git make` today, and ggml's Vulkan backend compiles its
shaders at build time — the flag alone fails at configure.
2. `-DGGML_VULKAN=OFF` → `ON` in the same cmake block; the flag list is written out
explicitly, so this is a one-word diff.
3. Runtime stage: add `mesa-vulkan-drivers`. Without a Vulkan **ICD inside the image** the
device node buys nothing — there is no `radeon_icd.json` in the container today.
4. `frank-tts-engine.container`: `AddDevice=/dev/dri` + `GroupAdd=keep-groups` — **not**
`renderD128`. On this hybrid box that node is the NVIDIA card; the iGPU is
`renderD129` (`readlink -f /sys/class/drm/renderD129/device/driver` → `amdgpu`).
5. Engine argv: `--device Vulkan0` — qwentts.cpp's tools take `--device <name>` at the
pinned commit.
Gate 1 recipe, already run and **PASSED**: `mesa-vulkan-drivers` + `vulkan-tools` in a
throwaway container off the same base, `--device /dev/dri`, then `vulkaninfo --text` and read
the `VkPhysicalDeviceMemoryProperties` heap sizes — no model, no load, no compute. The probe
trap: `vulkaninfo --batch` is not a flag in Ubuntu 24.04's `vulkan-tools` — it prints the help
page and exits 1, which reads like a driver failure. Every package involved has a candidate on
the host's apt (`vulkan-tools` 1.4.341, `libvulkan-dev` 1.4.341, `glslang-dev`/`glslang-tools`
16.2.0); the build stage runs on the digest-pinned Ubuntu 24.04 base, whose versions are older
but present. Script: `/home/dank/spikes/npu-tts/vk_probe.sh` on Dankclaw.
Constraints that do not relax for a co-tenant: `/dev/dri` passthrough needs the ComfyUI
pattern (`AddDevice` + `GroupAdd=keep-groups` + the world-writable udev rule) because
systemd user-unit spawns carry no supplementary groups; the 64 GiB swap at `/swap.img`
exists to protect co-tenants, and paging a KV pool is worse than the OOM it prevents;
`pp_dpm_fclk` reads `auto` (unheld), which only becomes a hazard if the NPU ever joins.
## 6. Re-visit condition
Retry the NPU when **a Linux loader claims the graph**: an `onnxruntime-genai-ryzenai`
build whose RyzenAI adapter takes the NuTTS-Air Full-Fusion graph on `RyzenAI-npu5`, or that
model appearing in a runtime's own supported catalog with a Linux runner. Then the
prerequisites are already mapped and priced: the gated NeuCodec encoder for cloned voices,
the `ref_text` transcripts, the 4096-token prompt budget, and 50 codes/s as the bar.

"""OKF v0.1 conformance linter for a docs bundle (default serverAppConfigs-docs).
Checks the hard rules of the Open Knowledge Format spec plus the maintenance
guidance, so "conforms to OKF" is a test and not a claim:
FRONTMATTER every non-reserved .md has parseable YAML frontmatter with a
non-empty `type` from the spec's value set
TYPE the value is one of reference / howto / tutorial / explanation
DESC `description` is present, non-blank, not the title, <= 120 chars,
and does not restate a fleet quantity
TIMESTAMP `timestamp` present, ISO 8601, not in the future
LENGTH lines between 1 and 500 inclusive
INDEX-FM no index.md may carry frontmatter (index.md is reserved)
LOG-DATE log.md date headings are `## YYYY-MM-DD` or `## YYYY-MM-DD — Title`,
one entry per date, newest first
INDEX-COVER every index.md links each of its sibling pages; the root index
links every page in the bundle
INDEX-NUM an index table row restates a fleet quantity — a digit run of
three or more, a digits-plus-unit figure, a port, or a
multiplier. Names (Qwen3.6, RDNA4, RTX 3090, PICO-8, P4) are
not quantities and are allowed
CITATIONS informational: pages with factual claims and no Citations
section are counted, never failed
LENGTH lines between 1 and 500 inclusive. A page may opt out of the
ceiling with `okf-exempt: length` in its frontmatter: AGENTS.md
makes one page per endpoint permanent, and an endpoint page with
a full Eras table cannot split without creating a second owner
of the same shape (tests/docs_completeness.bats enforces that)
Exit 0 when there are no violations.

"""Regenerate serverAppConfigs-docs/index.md from page frontmatter.
The root index is a locator (AGENTS.md -> *Documentation Policy*): one row per
page, one clause, no numbers. Hand-maintaining it is how rows go missing, and
the docs seam fails when a page is not linked from it, so it is generated:
* preamble everything above the first `## ` in the existing file is kept
verbatim (that is the curated statement of the vault's law)
* section from the page's directory, overridden by its frontmatter tags
(`endpoint` / `retired-endpoint` split the LLM pages)
* row text the page's frontmatter `description`, verbatim
A page with no description is a hard error rather than an empty cell, so the
generator cannot silently produce a silent index. Sections with no pages are
skipped. Deterministic: the same vault always yields the same bytes.
Sub-directory indices are hand-grouped (they carry curated prose), so they are
synced rather than regenerated: dead rows dropped, row text refreshed from the
page's description, uncovered siblings appended.

## Where the engine computes
CPU, and only CPU is compiled in: `Containerfile.engine` builds `qwentts.cpp` with
`-DGGML_VULKAN=OFF` written out explicitly, so the container carries `libggml-cpu` and no
other backend. The realistic accelerator is the gfx1151 iGPU behind that flag — plus
`/dev/dri` passthrough, the ComfyUI pattern — on the same payload and the same pinned

`frank-dragoon`, not a handover. Memory is not what decides that; shader contention is, and
the census plus both gates are in `report/tts-npu-spike-verdict-2026-10-19.md` §5.
**The Strix Halo NPU is not a door at all**: XDNA2 executes only precompiled AIE
partition programs, and AMD's own Linux runtime opens `/dev/accel/accel0`, succeeds at the

# Authentik Outpost Reference
Configuration lookup for the [[Authentik]] deployment: the live proxy-provider
inventory behind the guarded vhosts, the provisioning rules the embedded outpost
enforces, this fork's OAuth2 relying-party quirks, the LDAP provider objects, the
self-serve user-settings flow, and the live database shape. What the service is,
how it is deployed, wired and operated is [[Authentik]]; the three core
containers are [[Authentik Processes]].
## Live proxy-provider inventory
Live provider inventory (read from the `authentik-postgres` container with
read-only `SELECT`s, 2026-10-18). Nine proxy providers, all attached to outpost
`7e39655b-58d3-4fe6-a80a-513f31051217` ("authentik Embedded Outpost", 9
members in `authentik_outposts_outpost_providers`), all with
`internal_host = http://caddy:8017`, all carrying the **same three flow
UUIDs** (`default-authentication-flow`
`default-provider-authorization-implicit-consent`
`default-provider-invalidation-flow`), and each backed by an Application
(the `slug` column below):
| Provider pk | name | external_host | app slug |
|---|---|---|---|
| 1 | embedded-outpost | `https://www.franksdank.cloud` | caddy |
| 2 | search-proxy | `https://search.franksdank.cloud` | search |
| 4 | prometheus-proxy | `https://prometheus.franksdank.cloud` | prometheus |
| 5 | romm-proxy | `https://romm.franksdank.cloud` | romm |
| 6 | files-proxy | `https://files.franksdank.cloud` | files |
| 7 | loki-proxy | `https://loki.franksdank.cloud/` | loki |
| 8 | grafana-proxy | `https://grafana.franksdank.cloud/` | grafana-guard |
| 10 | seerr-proxy | `https://seerr.franksdank.cloud/` | seerr-guard |
| 13 | marreta-proxy | `https://marreta.franksdank.cloud` | marreta |
That is exactly the Caddyfile's guarded set (`dankclaw/Caddyfile:283-423`), so
the lockstep rule in [[Authentik]] holds today. Two corrections against the 2026-09-02 table:
**pk 13 (`marreta-proxy`) was added** when Marreta went onto the chain, and
**pk 3 (`hermes-proxy`) no longer exists at all** — `select … where id=3`
returns zero rows, so it is deleted, not "dormant"; its vhost survived but is
exempt-by-construction (`dankclaw/Caddyfile:179-191`). OAuth2 relying parties,
not proxy providers, so the proxy outpost does not deserialize them: pk 9
`grafana` (`grant_types = {authorization_code}`), pk 12 `Seerr OIDC`
(`grant_types = {}` — empty, i.e. still in the state the token-endpoint rule
below rejects), and pk 14 `Open WebUI`
(`grant_types = {authorization_code,refresh_token}`). Trailing slashes on
`external_host` (the runbook-recipe style) and bare origins both intercept
correctly — the outpost matches on hostname.
## Provisioning rules for proxy providers
Two provisioning rules, each verified live by an outage:
1. **All three flows are required.** A ProxyProvider created via raw API/ORM
with any of `authentication_flow`/`authorization_flow`/`invalidation_flow`
null wedges the embedded outpost's config fetch: the Rust side rejects the
whole config JSON (serde: `invalid type: null, expected a formatted UUID
string`), logs `Failed to fetch outpost from API, retrying in 3 seconds`
forever, and **everything behind the outpost dies at the next outpost
reload** — including hosts whose providers were fine (verified 2026-09-02
when three providers provisioned without any flows took down every guarded
vhost after a server restart). Backfill all three flows (copy from pk 1:
`default-authentication-flow`
`default-provider-authorization-implicit-consent` (the implicit-consent
authorization flow, `default-invalidation-flow`) and the retry loop
recovers on its next 3-second cycle. The silent killer: while the outpost
process keeps its last good in-memory config, everything works — the
outage only surfaces on restart/reload.
2. **Every proxy provider needs an attached Application.** The outpost
resolves the post-login redirect through the provider's application; a
provider with no app completes the login (authentik session established)
but bounces to authentik's own user UI (`/if/user/#/library`) instead of
the app. No error is logged anywhere — the SSO "works" and the app never
appears. Create the Application with `provider_id` set (the UI does this
automatically; raw API/ORM drives must do it explicitly).
## OAuth2 relying-party quirks (this fork, verified live 2026-08-31)
The Grafana RP provider (`grafana`, pk 9, confidential client) was created and
verified end-to-end via `ak shell` ORM drives. This fork's OAuth2 provider
implementation diverges from upstream in ways that bit us; all verified live:
- **Application row required.** `OAuth2Provider.objects.create()` does not
create the single-table-inheritance `Application` row; without it the flow
executor can never complete an authorize request. Create both rows.
- **`grant_types` defaults to empty.** Until the provider's `grant_types`
contains `"authorization_code"` (enum value with underscore), the token
endpoint rejects every exchange with `invalid_request`.
- **Token endpoint is form-encoded + Basic-auth only.** A JSON body makes
`parse_token_request` see no `grant_type` → `unsupported_grant_type`
POST-body client secrets are not accepted — authenticate the confidential
client with `Authorization: Basic base64(client_id:client_secret)`.
- **Provider resolution is by `client_id` query param** on the global
`/application/o/authorize/` route; per-slug authorize paths do not exist in
this build. Token/userinfo live at `/application/o/token/` and
`/application/o/userinfo/?api=1`.
- **Property-mapping evaluator is broken → userinfo returns `sub` only.**
`PropertyMappingEvaluator.evaluate(*args, **kwargs)` forwards kwargs to
`BaseEvaluator.evaluate(expression_source)`, so the first context kwarg
becomes the *expression source* instead of the context; every call raises a
swallowed `PropertyMappingExpressionException` and the claim is skipped.
Scope-grant filtering has the same class of bug: `ScopeMapping` has no
provider FK (linkage lives in the `ProviderPropertyMapping` through model)
so `filter(provider=...)` always yields an empty queryset and tokens asked
to carry scopes get zero. Net effect: userinfo/introspection answers with
`{sub}` only — email/groups/entitlements claims cannot be delivered by this
build until the evaluator is patched or upgraded. Clients consuming this
provider must key identity off `sub`.
- Scope mappings for this provider exist — `grafana-email-scope` and
`grafana-profile-scope` are both rows in `authentik_core_propertymapping`
(read-only `SELECT`, 2026-10-18) — and will start emitting claims the moment
the evaluator bug is fixed; no config change is needed then.
## LDAP provider objects (provisioned via `ak shell` ORM)
The LDAP outpost's own deployment — unit, image digest, published ports, token
env var — is in [[Authentik]]. The objects it serves:
Read from the live database (read-only `SELECT`s against the
`authentik-postgres` container, 2026-10-18):
| Object | Value |
|---|---|
| LDAP provider | `Jellyfin LDAP` (pk 11), base DN `dc=franksdank,dc=cloud`, `search_mode=direct`, `bind_mode=direct` |
| Bind DN | `cn=svc-jellyfin-ldap,ou=users,dc=franksdank,dc=cloud` *(unverified 2026-10-18: base DN confirmed in the DB, the `ou=users` path was not probed — an LDAP bind needs the bind secret)* |
| Service account | `svc-jellyfin-ldap` (user pk 8). **It is not passwordless**: its password field is a real hash, not Django's `!`-prefixed unusable marker (`starts_with(password,'!')` → `f`) — an earlier revision's "passwordless/unusable" claim is wrong, which matters because an account with a usable password can sign in through the ordinary password flow *(unverified 2026-10-18: whether anyone holds that password)* |
| Bind token | exactly one row for pk 8, **`intent=app_password`**, non-expiring — an earlier revision recorded `intent=verification`; the live value is `app_password` |
| RBAC role | `svc-jellyfin-ldap-search`, carrying exactly one object-level permission `authentik_providers_ldap.search_full_directory` (verified via `guardian_roleobjectpermission`) |
| Groups | `jellyfin_users`, `jellyfin_admins` (both exist in `authentik_core_group`) |
| Application | name `Jellyfin`, **slug `jellyfin-ldap`** (an earlier revision said slug `jellyfin`, which does not exist) |
Hard-won rules (the first is now contested by the live database):
- **Token intent: contested, do not trust either value blindly.** An earlier
revision asserted that a bind token with `intent=app_password` is rejected by
the flow's password stage with `Invalid password` and only
`intent=verification` passes. The live token for `svc-jellyfin-ldap` is
`app_password` (`authentik_core_token`, 2026-10-18), so either the rule is
wrong or the current Jellyfin bind path is not that token. Nothing observable
settles it today: the LDAP outpost's retained log holds only its 5-minute
`initialized direct binder` / `Update providers` config cycles and no bind
activity *(unverified 2026-10-18: no bind was performed — reproducing it
requires the bind secret)*. Re-verify with a real bind before changing the
token's intent either way.
- **Search needs `search_full_directory`.** Without the RBAC grant the
outpost returns only the bind user itself — a `(memberOf=…)` filter then
matches zero entries and the plugin logs `Found no users matching X`.
The permission is object-level on the provider; grant it via an RBAC role
and retest.
- `ak shell` import path for the provider model in 2026.8:
`from authentik.providers.ldap.models import LDAPProvider`.
- (unverified 2026-10-18: importing it outside a configured Django shell fails
with `ImproperlyConfigured`, and no `ak shell` was driven against the live
auth service for this check)*
## Self-serve user-settings flow (password change)
Users change their own account details through the `default-user-settings-flow`
(`https://auth.franksdank.cloud/if/flow/default-user-settings-flow/`) — the
target of the homepage footer's "account" link. It is a `stage_configuration`
designated flow, so it renders every bound `ConfigurableStage` for the logged-in
user.
Stages, in execution order (the `FlowStageBinding.order` field, not the M2M
insertion order):
| order | stage | type | what it does |
|---|---|---|---|
| 20 | `default-user-settings` | `PromptStage` | name / email / locale **+ password** |
| 100 | `default-user-settings-write` | `UserWriteStage` | writes the prompt data to the user |
**Password change is a prompt field, not a stage.** The `UserWriteStage`
writes whatever the preceding `PromptStage` collected: for the key `password`
it calls `user.set_password(value)` (`stages/user_write/stage.py`). So the fix
is a `password` field on the `default-user-settings` prompt
(`field_key=password`, `type=password`, `required=False`, order 204) — NOT a
`PasswordStage`. A `PasswordStage` is an *authentication* stage: its
`validate_password` runs `authenticate()` against the backends to check the
*current* password; it never sets a new one. (A `PasswordStage` was added on
2026-09-25 and removed the same day for exactly this reason.)
Two ORM gotchas: `Flow.stages.add()` fails on this through model
(`Can't bulk create a multi-table inherited model` — `FlowStageBinding` is
MTI), so create the `FlowStageBinding` row directly with an explicit `order`
and a prompt field is a `Prompt` row linked through `PromptStageField`
(`prompt_stage` + `prompt`; the order comes from `Prompt.order`).
**A blank password must not set an empty password.** `set_password("")` would
make the account log in with no password, so a validation policy
(`default-user-settings-no-empty-password`, bound to the prompt
`PromptStageValidationPolicy`) denies the form when `prompt_data["password"]`
is `""` and allows it when set. Verified with the `PolicyEvaluator`
(empty → deny, set → allow, absent → allow) and end-to-end by driving
`UserWriteStageView.update_user` on a throwaway user (new password valid, old
invalid).
## Live database shape
For live DB truth prefer the postgres container, and it works without any
credential — the local socket is trusted, so a read-only audit is just
`podman exec -i authentik-postgres psql -U authentik -d authentik -At -f -`
with SQL on stdin (quoting SQL through ssh+zsh otherwise fights you). Verify
before guessing: 2026.x renamed both tables and columns, and the models are
MTI all the way down — `authentik_core_provider` holds `id`, `name` and the
three `*_flow_id` columns; the proxy table is
`authentik_providers_proxy_proxyprovider` (doubled `proxy`) and its PK column
really is **`oauth2provider_ptr_id`** (proxy providers inherit the OAuth2
table in 2026.8), the LDAP table is
`authentik_providers_ldap_ldapprovider` with PK `provider_ptr_id`
`authentik_core_application` attaches to a provider through `provider_id`
(its PK is `policybindingmodel_ptr_id`, not `id`), and `authentik_outposts_outpost`
is keyed by `uuid`. So `Provider.objects.filter(type=…)` raising `FieldError`
is the same story from the ORM side: `type` lives in the subclass tables.
Never select secret columns (`client_secret`, `key`, `password`) into a log.

# Authentik Processes
The three core containers of the [[Authentik]] stack on Dankclaw. The two
outpost units are not covered here — they live on [[Authentik]] and
[[Authentik Outpost Reference]]. Server and worker run the same image; the
`command` selects the role (`server` / `worker`). Data persists under
`/home/dank/Containers/authentik/` as bind mounts (repo policy — no named
volumes), moved from `/home/dank/authentik/` in the 2026-09-01 quadlet
standardization; the retired stubs this page replaces recorded the pre-move
paths `/home/dank/authentik/data` (server and worker) and
`/home/dank/authentik/postgres` (database).
## authentik-postgres
The PostgreSQL 16 database for Authentik — the only stateful store in the stack
(users, flows, sessions, events). Sessions, caching, and WebSockets moved to
PostgreSQL in 2025.10 (Redis removed).
- **Image:** `docker.io/library/postgres:16-alpine`
- **Data:** `/home/dank/Containers/authentik/postgres` (bind mount; no named
volumes)
- **Health:** `pg_isready -d authentik -U authentik`
- **Retired wording:** the stub called this a "Compose service … in
`dankclaw/compose.yaml`"; the compose stack is gone and the unit is a quadlet.
- The side-by-side with `gitea-postgres` (network, published ports, secret
source, boot persistence) is owned by [[Postgres]].
## authentik-server
The Authentik server — the core, the admin API, and the embedded Caddy outpost.
It also serves the login page at `https://auth.franksdank.cloud`.
- **Unit:** `dankclaw/authentik/quadlet/authentik-server.container`
(`authentik-server.service`)
- **Image:** `ghcr.io/goauthentik/server:2026.8.3` (`command: server`)
- **Port:** `9000` (published) — the outpost, the admin API and the login UI all
live here
- **Data:** `/home/dank/Containers/authentik/data` (bind mount, shared with the
worker)
- **Health:** recorded by the retired stub as
`http://localhost:9000/-/health/`; superseded — [[Authentik]] → Operations
owns the live probe.
- **Retired wording:** the stub described "the Caddy `forward_auth` vhosts"
proxying here; the chain Caddy actually runs is [[Authentik]] → Caddy
integration.
## authentik-worker
The Authentik worker — background tasks: event processing, provider
synchronization, scheduled flows, and certificate renewal.
- **Unit:** `dankclaw/authentik/quadlet/authentik-worker.container`
(`authentik-worker.service`)
- **Image:** `ghcr.io/goauthentik/server:2026.8.3` (`command: worker`)
- **Runs as:** `0:0` (rootless: container root maps to the host user that owns
the data dir)
- **Data:** `/home/dank/Containers/authentik/data` (bind mount, shared with the
server)
- **No port** — the worker has no HTTP endpoint.

| 13 | marreta-proxy | `https://marreta.franksdank.cloud` | marreta |
That is exactly the Caddyfile's guarded set (`dankclaw/Caddyfile:283-423`), so
the lockstep rule holds today. Two corrections against the 2026-09-02 table:
**pk 13 (`marreta-proxy`) was added** when Marreta went onto the chain, and
**pk 3 (`hermes-proxy`) no longer exists at all** — `select … where id=3`
returns zero rows, so it is deleted, not "dormant"; its vhost survived but is
exempt-by-construction (`dankclaw/Caddyfile:179-191`). OAuth2 relying parties,
not proxy providers, so the proxy outpost does not deserialize them: pk 9
`grafana` (`grant_types = {authorization_code}`), pk 12 `Seerr OIDC`
(`grant_types = {}` — empty, i.e. still in the state the token-endpoint rule
below rejects), and pk 14 `Open WebUI`
(`grant_types = {authorization_code,refresh_token}`). Trailing slashes on
`external_host` (the runbook-recipe style) and bare origins both intercept
correctly — the outpost matches on hostname.
Two provisioning rules, each verified live by an outage:
1. **All three flows are required.** A ProxyProvider created via raw API/ORM
with any of `authentication_flow`/`authorization_flow`/`invalidation_flow`
null wedges the embedded outpost's config fetch: the Rust side rejects the
whole config JSON (serde: `invalid type: null, expected a formatted UUID
string`), logs `Failed to fetch outpost from API, retrying in 3 seconds`
forever, and **everything behind the outpost dies at the next outpost
reload** — including hosts whose providers were fine (verified 2026-09-02
when three providers provisioned without any flows took down every guarded
vhost after a server restart). Backfill all three flows (copy from pk 1:
`default-authentication-flow`,
`default-provider-authorization-implicit-consent` (the implicit-consent
authorization flow, `default-invalidation-flow`) and the retry loop
recovers on its next 3-second cycle. The silent killer: while the outpost
process keeps its last good in-memory config, everything works — the
outage only surfaces on restart/reload.
2. **Every proxy provider needs an attached Application.** The outpost
resolves the post-login redirect through the provider's application; a
provider with no app completes the login (authentik session established)
but bounces to authentik's own user UI (`/if/user/#/library`) instead of
the app. No error is logged anywhere — the SSO "works" and the app never
appears. Create the Application with `provider_id` set (the UI does this
automatically; raw API/ORM drives must do it explicitly).
## OAuth2 relying-party quirks (this fork, verified live 2026-08-31)
The Grafana RP provider (`grafana`, pk 9, confidential client) was created and
verified end-to-end via `ak shell` ORM drives. This fork's OAuth2 provider
implementation diverges from upstream in ways that bit us; all verified live:
- **Application row required.** `OAuth2Provider.objects.create()` does not
create the single-table-inheritance `Application` row; without it the flow
executor can never complete an authorize request. Create both rows.
- **`grant_types` defaults to empty.** Until the provider's `grant_types`
contains `"authorization_code"` (enum value with underscore), the token
endpoint rejects every exchange with `invalid_request`.
- **Token endpoint is form-encoded + Basic-auth only.** A JSON body makes
`parse_token_request` see no `grant_type` → `unsupported_grant_type`;
POST-body client secrets are not accepted — authenticate the confidential
client with `Authorization: Basic base64(client_id:client_secret)`.
- **Provider resolution is by `client_id` query param** on the global
`/application/o/authorize/` route; per-slug authorize paths do not exist in
this build. Token/userinfo live at `/application/o/token/` and
`/application/o/userinfo/?api=1`.
- **Property-mapping evaluator is broken → userinfo returns `sub` only.**
`PropertyMappingEvaluator.evaluate(*args, **kwargs)` forwards kwargs to
`BaseEvaluator.evaluate(expression_source)`, so the first context kwarg
becomes the *expression source* instead of the context; every call raises a
swallowed `PropertyMappingExpressionException` and the claim is skipped.
Scope-grant filtering has the same class of bug: `ScopeMapping` has no
provider FK (linkage lives in the `ProviderPropertyMapping` through model),
so `filter(provider=...)` always yields an empty queryset and tokens asked
to carry scopes get zero. Net effect: userinfo/introspection answers with
`{sub}` only — email/groups/entitlements claims cannot be delivered by this
build until the evaluator is patched or upgraded. Clients consuming this
provider must key identity off `sub`.
- Scope mappings for this provider exist — `grafana-email-scope` and
`grafana-profile-scope` are both rows in `authentik_core_propertymapping`
(read-only `SELECT`, 2026-10-18) — and will start emitting claims the moment
the evaluator bug is fixed; no config change is needed then.
The live proxy-provider inventory (the per-vhost `external_host` → app mapping)
the two provisioning rules the outpost enforces, and this fork's OAuth2
relying-party quirks are reference lookup: [[Authentik Outpost Reference]].

|---|---|
| LDAP provider | `Jellyfin LDAP` (pk 11), base DN `dc=franksdank,dc=cloud`, `search_mode=direct`, `bind_mode=direct` |
| Bind DN | `cn=svc-jellyfin-ldap,ou=users,dc=franksdank,dc=cloud` *(unverified 2026-10-18: base DN confirmed in the DB, the `ou=users` path was not probed — an LDAP bind needs the bind secret)* |
| Service account | `svc-jellyfin-ldap` (user pk 8). **It is not passwordless**: its password field is a real hash, not Django's `!`-prefixed unusable marker (`starts_with(password,'!')` → `f`) — the page's earlier "passwordless/unusable" claim is wrong, which matters because an account with a usable password can sign in through the ordinary password flow *(unverified 2026-10-18: whether anyone holds that password)* |
| Bind token | exactly one row for pk 8, **`intent=app_password`**, non-expiring — the page previously recorded `intent=verification`; the live value is `app_password` |
| RBAC role | `svc-jellyfin-ldap-search`, carrying exactly one object-level permission `authentik_providers_ldap.search_full_directory` (verified via `guardian_roleobjectpermission`) |
| Groups | `jellyfin_users`, `jellyfin_admins` (both exist in `authentik_core_group`) |
| Application | name `Jellyfin`, **slug `jellyfin-ldap`** (the page previously said slug `jellyfin`, which does not exist) |
Hard-won rules (the first is now contested by the live database):
- **Token intent: contested, do not trust either value blindly.** This page
long asserted that a bind token with `intent=app_password` is rejected by the
flow's password stage with `Invalid password` and only `intent=verification`
passes. The live token for `svc-jellyfin-ldap` is `app_password`
(`authentik_core_token`, 2026-10-18), so either the rule is wrong or the
current Jellyfin bind path is not that token. Nothing observable settles it
today: the LDAP outpost's retained log holds only its 5-minute
`initialized direct binder` / `Update providers` config cycles and no bind
activity *(unverified 2026-10-18: no bind was performed — reproducing it
requires the bind secret)*. Re-verify with a real bind before changing the
token's intent either way.
- **Search needs `search_full_directory`.** Without the RBAC grant the
outpost returns only the bind user itself — a `(memberOf=…)` filter then
matches zero entries and the plugin logs `Found no users matching X`.
The permission is object-level on the provider; grant it via an RBAC role
and retest.
- `ak shell` import path for the provider model in 2026.8:
`from authentik.providers.ldap.models import LDAPProvider`.

with `ImproperlyConfigured`, and no `ak shell` was driven against the live

## Self-serve user-settings flow (password change)
Users change their own account details through the `default-user-settings-flow`
(`https://auth.franksdank.cloud/if/flow/default-user-settings-flow/`) — the
target of the homepage footer's "account" link. It is a `stage_configuration`
designated flow, so it renders every bound `ConfigurableStage` for the logged-in
user.
Stages, in execution order (the `FlowStageBinding.order` field, not the M2M
insertion order):
| order | stage | type | what it does |
|---|---|---|---|
| 20 | `default-user-settings` | `PromptStage` | name / email / locale **+ password** |
| 100 | `default-user-settings-write` | `UserWriteStage` | writes the prompt data to the user |
**Password change is a prompt field, not a stage.** The `UserWriteStage`
writes whatever the preceding `PromptStage` collected: for the key `password`
it calls `user.set_password(value)` (`stages/user_write/stage.py`). So the fix
is a `password` field on the `default-user-settings` prompt
(`field_key=password`, `type=password`, `required=False`, order 204) — NOT a
`PasswordStage`. A `PasswordStage` is an *authentication* stage: its
`validate_password` runs `authenticate()` against the backends to check the
*current* password; it never sets a new one. (A `PasswordStage` was added on
2026-09-25 and removed the same day for exactly this reason.)
Two ORM gotchas: `Flow.stages.add()` fails on this through model
(`Can't bulk create a multi-table inherited model` — `FlowStageBinding` is
MTI), so create the `FlowStageBinding` row directly with an explicit `order`;
and a prompt field is a `Prompt` row linked through `PromptStageField`
(`prompt_stage` + `prompt`; the order comes from `Prompt.order`).
**A blank password must not set an empty password.** `set_password("")` would
make the account log in with no password, so a validation policy
(`default-user-settings-no-empty-password`, bound to the prompt via
`PromptStageValidationPolicy`) denies the form when `prompt_data["password"]`
is `""` and allows it when set. Verified with the `PolicyEvaluator`
(empty → deny, set → allow, absent → allow) and end-to-end by driving

before guessing: 2026.x renamed both tables and columns, and the models are
MTI all the way down — `authentik_core_provider` holds `id`, `name` and the
three `*_flow_id` columns; the proxy table is
`authentik_providers_proxy_proxyprovider` (doubled `proxy`) and its PK column
really is **`oauth2provider_ptr_id`** (proxy providers inherit the OAuth2
table in 2026.8), the LDAP table is
`authentik_providers_ldap_ldapprovider` with PK `provider_ptr_id`;
`authentik_core_application` attaches to a provider through `provider_id`
(its PK is `policybindingmodel_ptr_id`, not `id`), and `authentik_outposts_outpost`
is keyed by `uuid`. So `Provider.objects.filter(type=…)` raising `FieldError`
is the same story from the ORM side: `type` lives in the subclass tables.
Never select secret columns (`client_secret`, `key`, `password`) into a log.
- The live database's table and column names (the 2026.x renames, the MTI parent
keys, the read-only `psql` audit recipe) are reference lookup:

([[frank-archon]]). When this page was written the endpoint
was `frank-medium`: first llama.cpp's layer split
([[frank-medium-llamacpp-dflash2]], 2026-09-16 → 09-20), then from 2026-09-20
one vLLM-radiance process at `tensor_parallel_size 2`
([[frank-medium-radiance-mxfp4]], 2026-09-20 → 09-26). This page records why
true tensor parallelism was impossible on the previous board (TUF GAMING B650-E
WIFI), and what the 2026-09-20 board swap changed.
## The short answer
**The wall is gone.** On the B650-E, card #2 sat behind the chipset, whose
bridges could not route PCIe atomic operations. RCCL's kernels carry a hidden
hostcall-buffer parameter and ROCr refuses to supply it to a device without
atomics, so *no* RCCL collective or P2P operation could be dispatched on that
card — see the [measured matrix](#measured-matrix) and the
[2026-09-16 table](#the-same-gate-as-this-board-reports-it-2026-09-16) below.
On 2026-09-20 the board became an **ASUS ProArt B850-Creator WiFi NEO**, which
bifurcates the CPU's GPP ports **x8/x8**: the board-swap path this page
recommended, at B850 rather than X870E money. Both cards now hang off CPU root
ports (`00:01.1`, `00:01.3`), every bridge on both chains reads
`AtomicOpsCap: Routing+`, and **both endpoints read `AtomicOpsCtl: ReqEn+`** —
the exact precondition this page's own test plan named, and it is now
[measured](#measured-verdict-2026-09-20) rather than assumed.
What that bought:
- **Both cooperation modes now work, and they were both run.** vLLM TP=2 booted
and served (its R4D allreduce needs no RCCL collective at all), and llama.cpp
`--split-mode tensor` booted and served against an RCCL-backed build — so a
collective HAS been dispatched on this host since the swap.
- **TP=2 is the production shape.** It wins on every axis measured, by 2.1x on
decode and 3.6x at 4-way concurrency, and it replaced the layer split on the day
of measurement. The payload has moved since: the MXFP4 `frank-medium` shape is
retired 2026-09-26, and what runs today is the iq4r publisher under radiance
1.0.13 ([[frank-archon]]).
- **The drafter, not the collective, is what llama.cpp lost.** Its tensor mode
could not carry the DFlash2 drafter, which is the honest caveat on the
comparison below.
- **The bandwidth story moved too.** Both cards ride Gen5 x8 (~31.5 GB/s each):
card 0 effectively unchanged (was Gen4 x16), card 1 up ~16x (was Gen4 x1,
~1.97 GB/s). The M.2→PCIe riser plan is dead — `PCIEX16_2` holds card #2 now
and M.2_2 is free.
## The gate, in source
```cpp
void Device::checkAtomicSupport() { // rocclr/device/rocm/rocdevice.cpp:181
std::vector<amd::Device::LinkAttrType> link_attrs;
link_attrs.push_back(std::make_pair(LinkAttribute::kLinkAtomicSupport, 0));
if (findLinkInfo(cpu_agent_info_->fine_grain_pool, &link_attrs)) {
if (link_attrs[0].second == 1) {
info_.pcie_atomics_ = true; // no else branch
}
}
}
```
The flag is a **queried hardware property**, consumed at
`rocvirtual.cpp:3954` (the hostcall/AQL dispatch path), in `rocblit.cpp` (SDMA
copy paths) and exported as `hipDeviceProp.hostNativeAtomicSupported`. There is
no environment variable, module parameter, or sysfs toggle around it — verified
by grepping ROCclr for `getenv`/`HSA_*`/`ROCR_*`/`AMD_*` in the gate's
neighborhood: none. Writing the endpoint's Device Control 2 bit 6 by hand
(`setpci -s 0b:00.0 CAP_EXP+28.w=0440`) does nothing because the value is
consumed at driver probe time.
What has to be true upstream of it: every PCIe bridge on the GPU's path to the
CPU must advertise `AtomicOpsCap: Routing+`. On this board card #2's path
includes `05:00.0` and `06:09.0`, both `Routing-` — a **read-only capability
bit**, so no software can enable it.
### The same gate, as this board reports it (2026-09-16)
`lspci -vv` on dankserver. Card 0's chain is root port `00:01.1` → `01:00.0` →
`02:00.0` → `03:00.0`; card 1's is `00:02.1` → `05:00.0` → `06:00.0` →
`06:09.0` → `09:00.0` → `0a:00.0` → `0b:00.0`:
| Device | Role | `AtomicOpsCap` | `AtomicOpsCtl` | Link |
|---|---|---|---|---|
| `00:01.1` | CPU root port → PCIEX16_1 | Routing+ | — | x16 |
| `03:00.0` | **card 0** | 32bit+ 64bit+ | **ReqEn+** | x16 |
| `00:02.1` | CPU root port → chipset | **Routing+** | — | x4 |
| `05:00.0`, `06:00.0`, `06:09.0` | B650 bridges | **Routing−** | — | x1 at `06:09.0` |
| `09:00.0`, `0a:00.0` | PCIe switch ports | Routing+ | — | x1 (downgraded) |
| `0b:00.0` | **card 1** | 32bit+ 64bit+ | **ReqEn−** | x16 |
Three things fall out of that table, none of them in the source alone:
- **The CPU side is fine** — `00:02.1` is `Routing+`. The wall is inside the
chipset, not the platform, which is why a slot on CPU lanes is the fix.
- **The endpoint's own bit differs between the cards, and that is the kernel's
doing.** `pci_enable_atomic_ops_to_root()` walks the bridge chain and refuses
to set Requester Enable when any bridge cannot route atomics. ROCclr's
`pcie_atomics_` and the endpoint's `ReqEn` are two faces of one cause, and it
makes `lspci -vv -s <bdf> | grep AtomicOpsCtl` a one-command diagnosis: on
this host card 0 reads `ReqEn+` and card 1 `ReqEn−`.
- **Card 1's effective link is x1**, not the x16 its own capability block
advertises: `06:09.0` trained at x1, so ~2 GB/s is the real ceiling. That is a
bandwidth fact rather than an atomics one, and it only matters for
collectives — a 27B TP=2 allreduce is ≈5.6 ms/token at x1 against ≈1.4 ms at
x4. The layer split's boundary copy does not care.
## Re-measured 2026-09-20 (ProArt B850-Creator WiFi NEO)
`lspci -vv` after the board swap. Card 0's chain is `00:01.1` → `01:00.0` →
`02:00.0` → `03:00.0`; card 1's is `00:01.3` → `05:00.0` → `06:00.0` →
`07:00.0`. **No chipset bridge is in either path** — `00:02.1` now carries only
LAN/SATA/WiFi:
| Device | Role | `AtomicOpsCap` | `AtomicOpsCtl` | Link |
|---|---|---|---|---|
| `00:01.1` | CPU GPP → PCIEX16_1 | Routing+ | — | Gen5 x8 |
| `01:00.0` | card 0 switch upstream | Routing+ | — | Gen5 x8 |
| `02:00.0` | card 0 switch downstream | Routing+ | — | Gen5 x16 |
| `03:00.0` | **card 0** | 32bit+ 64bit+ | **ReqEn+** | Gen5 x16 (on-card) |
| `00:01.3` | CPU GPP → PCIEX16_2 | Routing+ | — | Gen5 x8 |
| `05:00.0` | card 1 switch upstream | Routing+ | — | Gen5 x8 |
| `06:00.0` | card 1 switch downstream | Routing+ | — | Gen5 x16 |
| `07:00.0` | **card 1** | 32bit+ 64bit+ | **ReqEn+** | Gen5 x16 (on-card) |
- Both endpoints read `CAP_EXP+28.w = 0x1440` — bit 6 set, which is the
kernel's `pci_enable_atomic_ops_to_root()` having walked a chain with no
`Routing-` bridge. Same one-command diagnosis, opposite answer.
- `dmesg` agrees on bandwidth: `252.056 Gb/s available PCIe bandwidth, limited
by 32.0 GT/s PCIe x8 link at 0000:00:01.1` (and `.13`) — ~31.5 GB/s per
card. DMI confirms the bifurcation: `PCIEX16(G5)_2`, "8x or x8".
- `rocm-smi --showtopo` reported `PCIE` between the cards (Navi 48 has no XGMI),
they were in separate IOMMU groups (15 and 20 — re-read 2026-10-18: still 15
and 20), and both root ports had ACS `ReqRedir+`, so this page inferred P2P
would hairpin at the root complex. **That inference is superseded:** the live
engine reports the two cards reaching each other's memory directly, which
[[frank-archon]] and [[Dankserver System Specs]] record. Plain P2P traffic
measured 45.27 GB/s bidirectional on the *old* board — DMA was never the gate,
atomics were.
- Kernel 7.0.0-31-generic with `iommu=pt` then; this host runs 7.0.0-38-generic
with `iommu=pt` today (`/proc/cmdline`, read 2026-10-18). Both were ruled out
as causes ([above](#ruled-out-empirically-do-not-re-derive)) and this host's
IOMMU posture is unchanged.
**Still unproven (as of 2026-09-20).** The gate that matters is ROCclr's
`checkAtomicSupport()` reading the `kLinkAtomicSupport` link attribute; the ReqEn
bit is the same cause seen from the kernel side, but no RCCL kernel had been
launched since the swap. Until the 2-rank probe runs — or a `--split-mode row`
boot that does *not* log `internal AllReduce init failed ... falling back to
meta-backend butterfly` — "collectives work here" was a strong expectation, not a
measurement. **RCCL never got that measurement**; what settled the operational
question instead is production traffic — radiance's TP=2 wire carries cross-rank
all-reduces over the direct P2P path and prints its own precision, and the
measured `wht6` banner with its exact-step bound is on [[frank-archon]].
## Measured matrix
Bare 2-rank `torch.distributed` (`backend=nccl`) on the two R9700s, no vLLM, no
model. Rank 0 = card #1 (CPU lanes), rank 1 = card #2 (chipset):
| Operation | rank 0 (card #1) | rank 1 (card #2) |
|---|---|---|
| `broadcast` | OK | **FAIL** `DistBackendError` |
| `all_reduce` | OK | **FAIL** |
| `barrier` | OK | **FAIL** |
| `send` / `recv` (P2P) | blocked, then timeout | **FAIL** |
| `all_gather` (after failure) | group unusable | — |
The `AMD_LOG_LEVEL=3` trace names the cause: `Pcie atomics not enabled, hostcall
not supported` → `AQL dispatch failed!` → `hipLaunchKernel` returns
`hipErrorIllegalState` for `ncclDevKernel_Generic_4(...)`. Nothing in vLLM or
RCCL mentions atomics; the runtime log is the only place it appears.
**`send`/`recv` failing is the decisive result**: it kills pipeline parallelism
as an option, because vLLM's PP stage handoff is exactly that primitive.
## Software escapes: closed, and the last one is now moot
Every row below was written under the old board. The last row — the only door
that was ever open — stopped mattering on 2026-09-20, because the hardware gate
it existed to route around no longer applies to this host.
| Idea | Finding |
|---|---|
| vLLM's IPC custom allreduce | **Gated off by a table keyed to CUDA sm versions** — `{9.0, 10.0, 10.3, 10.7}`; ROCm reports capability `12.0` for gfx1201, so the gate is `False`. `custom_ar` itself is compiled into the image. |
| ...and if that table were patched | Still insufficient: `broadcast`, `barrier`, and the TP logits `all_gather` have no non-RCCL path. |
| The radiance fork's own allreduce | Already present and *on by default* (`RADIANCE_USE_R4D_AR`, size gate `RADIANCE_AR_MAX_KB`): a one-shot P2P push allreduce wrapping `CudaCommunicator.all_reduce`, exchanging IPC handles over the **gloo** group. With the gate raised it covers prefill and decode, and `ncclDevKernel` disappears from the profile. But it does not intercept `PyNcclCommunicator.__init__`'s **warmup allreduce**, nor `pynccl_comm.all_gather` — both direct RCCL calls. |
| NCCL symmetric memory | Unavailable: the shipped RCCL advertises NCCL 2.30.4 but exposes no `ncclDevComm*` API, so torch's symmetric-memory path cannot run. |
| Prefill/decode disaggregation | Needs a KV-transfer connector plus coordination collectives; both out. |
| gloo for GPU work | CPU/TCP collectives — orders of magnitude too slow for per-layer TP. |
| **Rebuild RCCL so its kernels do not declare a hostcall buffer** | **OPEN — unverified.** The claim is that the hostcall requirement is triggered by device-side `printf`/`assert`, and that `-mprintf-kind=buffered` avoids it. Counter-evidence: RCCL's device source at `src/device/` contains **no live** `printf`, `assert`, or `__assertfail` (checked), so what makes its kernels declare `HiddenHostcallBuffer` is unexplained. The claim traces to search-result summaries, not a primary source. Cheap to settle once a host is available: recompile librccl with `-mprintf-kind=buffered`, dump a kernel's declared arguments (`roc-obj-extract` + `llvm-readelf --notes`) and look for `hidden_hostcall_buffer`; if it is gone, a 2-rank probe should dispatch. **Stop and mask the service first** — see the note below. |
## Bandwidth: why x4 is enough
A 27B TP=2 allreduce at batch 4 moves roughly
$2 \times \text{batch} \times \text{hidden} \times 2\ \text{bytes} \approx 160\ \text{KB}$
per layer per forward pass; across ~62 layers that is **≈10 MB per token-step**,
or **~1.4 ms at PCIe 4.0 x4** (~7.9 GB/s), and under 0.4 ms at the Gen5 x8
~31.5 GB/s each card now has. TP is compute-bound here, not interconnect-bound.
That is why the cheap option (the M.2 riser) and the expensive one (the board
swap) were both considered adequate on bandwidth alone — and why the board that
landed, at x8/x8, clears the arithmetic with room to spare.
## Ruled out empirically (do not re-derive)
- Kernel versions 7.0.0-28 / -30 / -31 — byte-identical failure.
- `iommu=pt`, and `amd_iommu=off` is unrelated (that was a Dankclaw prefill knob).
- P2P hardware: 45.274 GB/s bidirectional between the cards works fine — plain
memory traffic is not the problem; *atomic* routing is.
- A from-source librccl rebuild: identical failure at the identical call path.
- Every NCCL transport/algorithm knob.
- A one-card test proves nothing: NCCL short-circuits at `world_size=1`, which
is exactly why the two replicas work at all.
- Independent corroboration: StillDeadcode/vllm-radiance Codeberg issue #22 —
different host, same image, kernel 7.0.0-30, same `enqueue.cc` failure.
## Measured verdict (2026-09-20)
Both cooperation modes were run on this host on 2026-09-20 — the same salted
10-prompt battery (`scripts/bench-conversation.py`), the service stopped and
masked between arms. The arm table is [[frank-medium-radiance-mxfp4]]'s bench of
record (arms R = radiance TP=2 + DFlash2 as deployed, I = the llama.cpp layer
split that preceded it, L = llama.cpp `--split-mode tensor` against RCCL); this
page keeps only the verdict. **TP=2 won on every axis — roughly 2.1× decode and
3.6× at 4-way concurrency over the layer split — and replaced the layer split the
day of measurement.**
Arm L carries a caveat no flag can remove: llama.cpp's tensor mode could not load
the DFlash2 drafter (it aborts at `ggml-backend.cpp:941` — a draft weight
pre-allocated on the non-primary device has no backend once `n_copies == 1`), so
it decoded **without** speculation while the other arms decoded with it; and part
of R's margin over I is the 4-bit MXFP4 checkpoint, not the parallelism.
Two numbers elsewhere on this page are therefore not interchangeable:
- The 272 t/s recorded 2026-09-16 is **prefill**, on a **butterfly** allreduce,
with RCCL off, on the old board. It was never a TP decode number, and its
paired decode figure is in "The third path" below.
- The butterfly tensor arm and the RCCL tensor arm a day later are the same shape
family on different collective paths; the measured pair lives with
[[frank-medium-radiance-mxfp4]]'s arms.
RCCL needs PCIe atomics on *every* participating GPU — the gate the old board
failed. vLLM's R4D one-shot allreduce dispatches no collective at all, which is
why TP=2 runs today rather than merely "being unblocked": the image ships TheRock
RCCL, and TheRock carries no gfx1201 device code (`invalid device function`), so
radiance could not have used RCCL on this host even with atomics routed. Ubuntu's
RCCL 2.27 does carry gfx1201 kernels, and that is what arm L linked against.
**Rule for any future multi-GPU collective experiment: stop and mask the
production service first**, per the benchmarking policy, or run it on a host that
is not serving users. The production service is `frank-archon`, a **root** unit,
so on Dankserver that is `sudo systemctl stop frank-archon && sudo systemctl
mask frank-archon` (`scripts/frank-archon.service`; never `disable` — that
deletes the unit file, and `mask` is what the bench policy prescribes). The
2026-09-20 wording below — `systemctl --user stop frank-medium && systemctl
--user mask frank-medium`, frank-medium being a rootless quadlet — is retired
with that service, which today reports `not-found` (read 2026-10-18).
This is not theoretical: on 2026-09-16 a bare RCCL P2P probe was run against the live
service; the host went hard down ~20 minutes later (no ARP, no ICMP, required a
power cycle). The mechanism is not proven, but a hung AQL dispatch wedging the
GPU driver is a plausible cause and this host has precedent for going
unreachable until a power cycle.
## The third path (production in the layer-split era): llama.cpp's layer split
Everything above is about *collectives*, and vLLM cannot proceed without them
in any of its parallelisms — TP needs a per-layer allreduce, and PP's stage
handoff is a p2p `send`/`recv` of the hidden state, the primitive this host
also fails. **llama.cpp's `--split-mode layer` needs no collective at all**:
layers are distributed across the cards and the boundary activation is a
plain per-backend copy, once per forward pass. No RCCL kernel is ever launched
on the second card, so the atomics gate never comes up.
That is what `frank-medium` ran from 2026-09-16 to 09-20
([[frank-medium-llamacpp-dflash2]]): one process, one model, both cards,
262144 context. Its measured layer-split rates are that page's; this host's
tensor arm under the butterfly fallback measured 272 t/s prefill / 26.3 tok/s
decode. **That tensor number is not a prediction for an RCCL-backed build** — it
is what tensor split costs when the allreduce degrades to a meta-backend
butterfly, and it is the number the board-swap path exists to retire.
The ranking therefore changed twice. On 2026-09-16: software already gets both
cards onto one model, so the hardware fix stopped being a capability question
and became a performance one — *tensor* parallelism, ~40 % decode, plus one
pooled KV instead of two independent 122k-token pools. On 2026-09-20 the
hardware half of that question was answered by the board swap; the llama.cpp
measurement half never ran, and `GGML_HIP_RCCL` still defaults `OFF` in
`scripts/build-llama-rdna4.sh:41` (re-read 2026-10-18) for exactly the reason
this page documents — moot while no llama.cpp shape is deployed on this host.
## What would change the answer
- ~~An RCCL build whose kernels stop declaring a hostcall buffer~~ — **moot
since 2026-09-20.** That door only mattered while the hardware gate could not
be passed; the board swap passes it. The `-mprintf-kind=buffered` hypothesis
and its counter-evidence stay in the escape table for the record.
- The symmetric-kernel path inside RCCL, if a release ever ships the device API
(`ncclDevComm*`) that torch's symmetric-memory path needs. The shipped TheRock
nightly (`~/.local/share/rocm-7.14.0a20260624/lib/librccl.so.1`) still does
not.
- ~~Firmware or an AGESA update that makes the chipset bridges advertise atomic
routing~~ — arrived as new silicon instead.
- A GPU-side workaround: none found in ROCclr, and the gate is per-device,
queried once at probe.

# FastFlowLM NPU Inference
FastFlowLM (FLM) runs LLMs entirely on the AMD Ryzen AI NPU. It targets XDNA2 chips: Strix, Strix Halo, Kraken, and Gorgon Point. The project describes itself as "Ollama, but deeply optimized for NPUs." As of 2026-08-16, FLM was installed on Dankclaw, the NPU validated, and `frank-zealot` (port 52625) served in production — that arrangement ended with the 2026-09-11 retirement (see the banner above). See Promotion.
## Verdict (2026-08-16)
- The NPU is a complement, not a replacement. It fits dense models up to about 9B.
- Qwen3.8-27B (dense) cannot run on the NPU. No FLM build exists and the memory budget is too small.
- Qwen3.6-35B-A3B has an official FLM build (Q4_KS). AMD benchmarks it on a 96 GB machine. It probably does not fit the 30 GiB budget of Dankclaw.
- Realistic first candidates: Qwen3.5-9B, Qwen3-8B, gpt-oss-20b (at the budget edge).
- **Landed 2026-08-16:** gpt-oss-20b serves on the NPU at 19.3 t/s decode, concurrently with the PP head. See Measured Results.
- The memlock limit was the setup blocker. Fixed 2026-08-16 via `/etc/security/limits.d/99-flm-memlock.conf`.
## What FastFlowLM Is
FLM is an NPU-first inference runtime. It started as a 2025 university project (University of Rhode Island, Ken Qing Yang). The team joined AMD on 2026-07-17. The repository moved to the ROCm organization on 2026-08-11 as v1.0.0.
Key properties, per the project README and docs:
- Runs fully on the NPU. No GPU or CPU load during inference.
- CLI mode (`flm run <tag>`) and server mode (`flm serve <tag>`).
- Server mode exposes a REST API and an OpenAI-compatible API. Default port is 52625.
- Models are not GGUF. FLM downloads pre-compiled kernel packs (built with AMD IRON + AIE-MLIR) from Hugging Face.
- Context lengths up to 256k tokens on listed models.
- Vision, audio, embedding, and MoE model support.
- Runtime is about 17 MB. Orchestration code is MIT-licensed. Kernels are free for commercial use.
- Models store in `~/.config/flm/` (Linux). Override with `FLM_MODEL_PATH`.
## NPU Hardware on Dankclaw
Dankclaw runs an AMD Ryzen AI MAX+ 395 (Strix Halo). The chip integrates an XDNA2 NPU
with 50 TOPS of compute and, crucially, **no dedicated VRAM** - it shares system memory
via the IOMMU SVA mapping. The budget this page reasons about - 29 GiB usable at
4800 MT/s LPDDR5X - is the 2026-08 host state; the live figure is [[Dankclaw System Specs]].
Live verification on Dankclaw, 2026-08-16:
```
$ flm validate
[FLM] Fetching models from: /opt/fastflowlm/share/flm/model_list.json
[Linux] Kernel: 7.0.0-29-generic
[Linux] NPU: /dev/accel/accel0 with 8 columns
[Linux] NPU FW Version: 1.1.2.65
[Linux] amdxdna version: 0.7
[ERROR] Memlock limit is too low (8MB). Please raise the limit or set to infinity.
```
- Kernel 7.0.0-29-generic shipped the `amdxdna` driver in-tree, loaded. The host now runs 7.0.0-38-generic and the driver is still bound (`lspci -k -s c6:00.1` → `Kernel driver in use: amdxdna`, read 2026-10-18).
- Firmware 1.1.2.65 meets the 1.1.0.0 minimum.
- The XRT runtime packages (`libxrt2`, `libxrt-npu2`) are installed — still installed on 2026-10-18 (`dpkg -l` → `libxrt2 1:2.21.75+dfsg-4`, `libxrt-npu2 1:2.21.75+dfsg-4`).
- The only failure is the memlock ulimit (8 MB). FLM needs `unlimited`.
- Ubuntu 26.04 is not on the FLM supported-distro list (24.04, 25.10, Arch, generic). Validation passes anyway. Treat 26.04 as "generic Linux, working".
## Memory Model
The NPU allocates from system RAM. AMD/Microsoft enforce an internal cap of about half of total system RAM for NPU use. The gpt-oss model card states a cap of about 15.6 GB on a 32 GB machine, which is half.
Budget math for this fleet:
| Machine | RAM | NPU budget (approx. half) |
|---------|-----|---------------------------|
| Dankclaw (Strix Halo) | 30 GiB | ~15 GiB |
| Dankserver (Ryzen 7 7700X) | 62 GB | no NPU |
| FLM bench box (Kraken Point) | 32 or 96 GB | ~16 or ~48 GB |
The half-of-RAM gate scales with host RAM - live figures in [[Dankclaw System Specs]]
and [[Dankserver System Specs]]. The live gate on Dankclaw is still `flm validate`
(it owns the current number).
Weight sizes (approximate, Q4-class):
| Model | Quant | Weights | Fits ~15 GiB budget? |
|-------|-------|---------|----------------------|
| Qwen3.5-9B | Q4_1 | ~5.5 GB | yes |
| Qwen3-8B | Q4_1 | ~5 GB | yes |
| gpt-oss-20b (MoE, 3.6B active) | Q4_1 | ~15.1 GB | at the edge |
| Qwen3.6-35B-A3B (MoE, 3B active) | Q4_KS | ~20 GB | no, unproven at 30 GiB |
| Qwen3.8-27B (dense) | any Q4 | ~16 GB+ | no build exists |
Do not load a model larger than the budget first. An oversized load can starve the unified pool and crash the box while production services still run.
## Supported Models (Qwen family, plus gpt-oss)

## Published Benchmarks (FLM, vendor numbers)
All vendor results come from AMD Ryzen AI 7 350 (Kraken Point, 40 TOPS NPU) boxes under the default NPU power mode (Performance). Our NPU is a 50 TOPS Strix Halo XDNA2. Treat these numbers as directional, not as our expected speed.

- PP and NPU together cost 2.2 GiB + NPU model + ~2 GiB of headroom. The then-current
PP split (head + 3090 worker, 2026-08 era - see [[frank-redo-2026-08-17]]) decoded at
14-18 t/s for the 27B dense model, so an NPU offload would free the head or upgrade
the worker's model.
The vendor also claims "over 10x more power-efficient" versus GPU. That is a marketing claim. We have not measured it.
## Fit to the Frank Program
| Our model | NPU verdict |
|-----------|-------------|
| Qwen3.8-27B UD-Q8_K_XL (Dankclaw, dense) | No. No FLM build. ~16 GB+ even at Q4. Exceeds the ~15 GiB budget. |
| Qwen3.6-35B-A3B (Dankserver, MoE) | Unproven. Official build exists. Vendor bench ran on 96 GB RAM. A 30 GiB box has ~15 GiB for the NPU. Test last, with the service stopped. |
| Qwen3.5-9B / Qwen3-8B | Yes, the realistic tier. ~5-6 GB. Leaves room for KV and the OS. |
| gpt-oss-20b (MoE) | **Landed.** Weights are 13.8 GB on disk (q4nx). The model holds ~15 GiB resident on the NPU. Decode is 19.3 t/s. See Measured Results. |
Proposed role: a small, always-on, low-power endpoint for triage, summarization, embeddings, or agent side-tasks on the Dankclaw NPU. It frees the iGPU and the 3090 for the 27B/35B workloads. It does not replace either.
## Install State on Dankclaw (verified 2026-08-16)
- `fastflowlm 1.0.1` installed (deb, upgraded from 0.9.45-12-ga6bd056 on 2026-08-17). `flm` at `/usr/bin/flm`. The 0.9.45 runtime refused the qwythos pack, which declares `flm_version` 1.0.0.
- `libxrt2` / `libxrt-npu2` (Xilinx Runtime) installed.
- `/dev/accel/accel0` present. `flm validate` passed fully. (Re-read 2026-10-18: `/dev/accel/accel0` is still present and `fastflowlm 1.0.1` is still installed, but the endpoint is retired — `frank-npu.service` masked, no listener on 52625.)
- Memlock fixed: `/etc/security/limits.d/99-flm-memlock.conf` sets soft and hard memlock to unlimited. A fresh sshd session picks it up via pam_limits. No reboot needed.
- `gpt-oss:20b` pulled (4/4 files verified, 13.8 GB `model.q4nx` + tokenizer) into `~/.config/flm/models/GPT-OSS-20B-NPU2/`.
- `qwythos:9b` (Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated-NPU2) installed 2026-08-17 via `flm-add.py` (downloaded from the HF repo; stdlib-only, no pip needed). Tag registered in the user registry `~/.config/flm/model_list.json` (a copy of the v1.0.1 system registry + the custom entry); kernels symlinked `~/.config/flm/xclbins/Huihui-...-NPU2 -> /opt/fastflowlm/share/flm/xclbins/Qwen3.5-9B-NPU2`. The service env exports `FLM_CONFIG_PATH` and `FLM_XCLBIN_PATH` so the tag resolves (without them flm hits the unknown-tag fallback, see the incident below).
- `flm serve gpt-oss:20b --host 0.0.0.0 -p 52625 --pmode performance` runs as a nohup process. It is not a systemd unit. It does not survive a reboot.
- The `llama-server` (frank-dragoon, the PP head) holds an fd on `/dev/accel/accel0` from its own startup (device enumeration, not compute). FLM opened the same device concurrently without conflict. Verified live 2026-08-16.
## Measured Results (2026-08-16, gpt-oss-20b on the Dankclaw NPU)
Conditions: `--pmode performance`, PP head (27B, port 7770) serving concurrently, 5.5 GiB system RAM headroom steady-state, NPU resident footprint ~15 GiB.
| Run | Prompt tok | Compl tok | Wall s | Prefill t/s | Decode t/s | KV occ % |
|-----|-----------:|----------:|-------:|------------:|-----------:|---------:|
| 1 (smoke) | 74 | 63 | 7.2 | 19.5 | 19.3 | 1.7 |
| 2 (160-tok prompt) | 161 | 256 | 17.4 | 40.8 | 19.3 | 5.1 |
| 3 (95-tok prompt, 512 out) | 95 | 512 | 30.8 | 24.3 | 19.3 | n/a |
Decode is flat at 19.3 t/s across all three runs. Output includes `reasoning_content` (gpt-oss is a reasoning model). At `max_tokens 256` one run spent its whole budget thinking and returned empty content. Give it 500+ tokens or strip reasoning in the client.
Long-context prefill is not yet measured (runs 1-3 used under 200 prompt tokens). The 35B-A3B step remains untested.
## Model Bakeoff (measured 2026-08-16, 4 models)
All runs on the Dankclaw NPU (50 TOPS Strix Halo), single stream, `--pmode performance`, PP head (frank-dragoon) serving concurrently on 7770. Decode t/s is the FLM-reported rate. Vision accuracy = ground-truth elements out of 4 (text SPECTRUM, red circle left, blue square right, three green triangles bottom).
| Model | Tag | Weights | Decode t/s (short) | 8k prefill t/s | 8k decode t/s | Vision decode t/s | Vision accuracy | Max ctx (registry) |
|-------|-----|---------|-------------------:|---------------:|--------------:|------------------:|----------------|--------------------|
| Gemma4-E4B | `gemma4-it:e4b` | 6.8 GB + 912 MB audio | 12.2 | 582 | 9.9 | 11.7 | 4/4 | 32768 |
| Qwen3.5-9B | `qwen3.5:9b` | 7.3 GB | 7.2 | 343 | 6.6 | 7.3 | 4/4 | 32768 |
| GPT-OSS-20B | `gpt-oss:20b` | 13.8 GB | 19.3 | 378 | 16.9 | n/a (no vision) | 0/4 | **8192** |
| Qwen3.6-35B-A3B | `qwen3.6-moe:35b-a3b` | 22.2 GB | 12.7 | 207 | 11.2 | 12.7 | 4/4 | 32768 |
Notes:
- gpt-oss:20b is the fastest decoder (MoE, 3.6B active) but its KV cache fills at ~8k tokens (98.85% occupancy at 7,926; requests past ~8k return 400). It has no vision encoder.
- 35B-A3B loads 28-29 GiB resident. It works but leaves ~1.5 GiB headroom with the PP head running. Do not run it alongside the head at full load.
- Vision prefill for the two vision models with ~720 token image input: gemma 141 t/s, qwen3.5 176 t/s, 35B-A3B 68 t/s.
- All four comply with the same image at 4/4 elements except gpt-oss, which cannot see it.
## Promotion (2026-08-16)
`frank-zealot` then ran the NPU endpoint on Dankclaw (2026-08; the name was reused
twice after this window - see the banner - and the NPU unit today is `frank-npu`,
masked). Unit: `scripts/frank-zealot.service` (symlinked into `/etc/systemd/system`),
wrapper `scripts/serve-flm-small.sh`, tunables `scripts/frank-zealot.env`.
`LimitMEMLOCK=infinity` is set in the unit. Default model: `gemma4-it:e4b`. Swap
`FLM_MODEL` in the env to switch.
### Boot policy (2026-08-17)
The `frank-zealot` unit is disabled for boot. Only the PP pair (`frank-dragoon` + `frank-pp-worker`) starts at boot. The unit file was removed from `/etc/systemd/system`; the running FLM service keeps serving until stopped or rebooted. To restore the endpoint, run these commands on Dankclaw:
```
sudo ln -sf /home/dank/vllmScripts/scripts/frank-zealot.service /etc/systemd/system/frank-zealot.service
sudo systemctl daemon-reload
sudo systemctl enable frank-zealot
```
Live config (2026-08-16): `FLM_PMODE=turbo`, `FLM_ASR=1` (loads Whisper-V3-Turbo-NPU2; exposes `/v1/audio/transcriptions`), `FLM_CTX_LEN=131072` (verified max — Gemma4 natively supports 128K and the NPU budget fits it; KV occupancy measured at 0.11% for a 123-token exchange, decode 12.0 t/s, 13 GiB headroom).
The PP split was renamed `frank-pp-head` → `frank-dragoon` (2026-08-16, commit `48142f5`).
Model swap (2026-08-16, commit `50c55ee`): `FLM_MODEL=qwen3.6-moe:35b-a3b`, `FLM_CTX_LEN=262144` (native max), `FLM_PMODE=turbo`, `FLM_ASR=1` kept. Decode measured 12.5-13.1 t/s. The Gemma4 live config above (131072 ctx) applied to `gemma4-it:e4b`. Swap `FLM_MODEL` and `FLM_CTX_LEN` back to restore it.
Model swap (2026-08-17, commit `c85ff6c`): `FLM_MODEL=qwythos:9b` (Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated-NPU2, Q4NX 7.76 GB). The pack installs through `flm-add` (user registry `~/.config/flm/model_list.json` + user xclbins `~/.config/flm/xclbins`, kernels symlinked from official `Qwen3.5-9B-NPU2`). Runtime upgraded to FLM 1.0.1 first (see Install State). `FLM_CTX_LEN=262144` native max (Qwen3.5-9B hybrid: 8 of 32 layers full attention, so KV stays small; occupancy 0.008% at 21 tokens). `FLM_PMODE=turbo`, `FLM_ASR=1` kept. The env file now exports `FLM_CONFIG_PATH` / `FLM_XCLBIN_PATH` — required, or flm treats the tag as unknown and silently serves llama3.2:1b. `qwen3.6-moe:35b-a3b` files stay installed for rollback. pi client entry (`~/.pi/agent/models.json` on dankware): id `qwythos:9b`, ctx 262144, input `[text]` (pack has no vision weights), compat `supportsDeveloperRole: false` kept.
## Parallel Streams (measured 2026-08-16)
The NPU serializes generations. It runs exactly one stream at a time. Extra streams queue in FIFO order. FLM server flags `--socket` (default 10) and `--q-len` (default 10) cap queue depth only. They do not add concurrency.
Concurrent-request test, gpt-oss-20b, 128-token cap per stream:
| Streams | Wall s | Aggregate t/s | Per-stream wall s |
|--------:|-------:|--------------:|-------------------|
| 1 | 10.6 | 12.1 | 10.6 |
| 2 | 21.1 | 12.0 | 10.8 / 21.1 |
| 4 | 41.1 | 11.6 | 10.9 / 21.6 / 32.4 / 41.1 |
The 4-stream wall times form a near-perfect 10.7 s ladder. Each stream self-reports 19.3 t/s decode, counting only its own active slices. Trust per-stream wall time, not the self-reported speed, under concurrency.
Consequence: the NPU endpoint is a single lane. It suits low-frequency background work (triage, summarization, agent side-tasks). It does not suit interactive chat for several simultaneous users. The 27B llama.cpp service, by contrast, runs PARALLEL=2 with true concurrent slots.
## Test Runbook
This runbook targets a retired endpoint; keep it as the procedure if the NPU is
ever revived.
**Host RAM availability.** The gate is half of system RAM by default - a relic of the
install: the endpoint ran on a machine that presented 30 GiB of system RAM; on today's
box that ceiling is far larger (live figure: [[Dankclaw System Specs]]). Check free RAM
first, or stop
the service the way the bench policy requires (`sudo systemctl stop
frank-dragoon && sudo systemctl mask frank-dragoon` — self-healing would
otherwise restart it). The NPU shares the unified pool with everything else on
the box.

1. Raise memlock. Add `* soft memlock unlimited` and `* hard memlock unlimited` to `/etc/security/limits.conf`. Then reboot. For a systemd unit, set `LimitMEMLOCK=infinity` instead.
2. Verify the NPU. Run `flm validate`. Run `xrt-smi examine`. Both must show the NPU. `flm validate` uses the kernel device. `flm run` uses XRT. A passing validate does not guarantee XRT sees the device.
3. Smoke test. Run `flm run qwen3.5:4b`. Toggle `/verbose` for performance reporting. Type `/bye` to exit.
4. Server mode. Run `flm serve qwen3.5:4b`. The default port is 52625. Use a scratch port if 52625 is taken. Never 7770.
5. Bench. Measure decode and prefill t/s at 1k/4k/16k starting context. Record to this page.
6. Step up in size: 9B, then gpt-oss-20b.
7. Attempt `qwen3.6-moe:35b-a3b` only after the smaller runs succeed, and only with the production service stopped. Watch `free -h` during the model download and load.
## Registering packs absent from the catalog (NPU2)
Use when adding a non-catalog NPU2 pack (an extraction or fine-tuned model)
to the FLM registry. Registry facts: user registry
`/home/dank/.config/flm/model_list.json`, shape
`{"model_path": "models", "models": {"<tag>": {"<size>": {name, url,
file_url, size, flm_min_version, files[], vlm, default_context_length,
max_prefill_len, details{format:"NPU2", family, …}, label[]}}}}`; serve
resolves tags through `FLM_CONFIG_PATH` at startup, and `flm list` with the
env var set lists custom tags (`⏬` = not downloaded).
1. Back up the registry JSON first (`cp -a`).
2. Insert the entry via a python json edit + atomic `os.replace`. Set
`files` to the FULL HF file list — **including `vision_weight.q4nx` even
for text-only packs**: the qwen3.5-family loader opens it unconditionally
and a missing file makes the first request HANG silently (no error log).
3. **Do not use `flm pull <tag>` for custom entries** — it throws
`json.exception out_of_range key '<tag>:<size>' not found` while building
the download list. Place files manually into
`/home/dank/.config/flm/models/<PackName>/` with
`curl -sfL "https://huggingface.co/<repo>/resolve/main/<file>?download=true"`
— plain `raw/main/<file>` returns 135-byte LFS pointer stubs, not
weights; verify byte counts against the HF tree API before trusting a
download.
4. Kernel packs: copy from the same-shape family pack (shape-match
`config.json` on hidden_size/num_hidden_layers/head_dim first) into
`/opt/fastflowlm/share/flm/xclbins/<PackName>/` via `sudo cp -a`
(root-owned dir).
5. Deploy/restart the serve unit (the deploy path, not ad-hoc restarts) so
the new process loads with all files present.
6. Verify with a REAL completion request (`model: "<tag>:<size>"`) —
`/v1/models` alone proves registration, not loadability.
Hard constraints: only ONE `flm serve` process can hold the NPU hardware
context — a second concurrent serve process fails every load with
`DRM_IOCTL_AMDXDNA_CREATE_HWCTX err=-22` (aie2 mgmt msg opcode 0x2 status
0x2000003); never run scratch/verify instances while production holds the
NPU. Tag switching happens INSIDE one serve process; the first request
after a model switch pays ~6–11 s cold-load cost (visible in
`usage.load_duration`). Over ssh, never `pkill -f "<pattern>"` with a
pattern present in your own command line — use bracket-guarded patterns
(`[q]wen3.5:4b`) or exact PIDs.
## Tag load-failure diagnosis (200 with an error body)
`POST /v1/chat/completions` answers **HTTP 200** with a flat
`{"error":"Failed to load <tag> model!"}` and no `choices`; `/v1/completions`
returns a nested OpenAI-shaped `server_error` (code 500) also under HTTP
200. A status-code-only client reads this as a successful empty completion —
**always check for the `error` key**. Two distinct causes, distinguished via
`journalctl -u <flm-service> --full`:
1. **Unknown tag** (not in the registry): immediate error, nothing loaded.
Correct behavior, not a bug.
2. **Registered tag whose kernel pack is missing**: FLM resolves the tag,
downloads missing weight files on the fly (first request hangs ~90–110 s),
then fails `Failed to load model: No such file
'/home/dank/.config/flm/xclbins/<PackName>/<kernel>.xclbin'`; subsequent
attempts fail fast (~2 s). Root cause: the serve script exports
`FLM_XCLBIN_PATH=/home/dank/.config/flm/xclbins` (user dir), so every
kernel lookup resolves under the user dir, which only contains symlinks
someone linked. **A tag listed in `/v1/models` is NOT proof it is
loadable on this host.** Fix: one symlink per missing pack
(`ln -s /opt/fastflowlm/share/flm/xclbins/<PackName>
/home/dank/.config/flm/xclbins/<PackName>`) — verified live: after the
symlink the first request loaded and answered in 7.4 s wall.
Switch-cost behavior: the `model` field routes per-request (no restart
needed); a request whose model differs from the resident one triggers a full
reload (7–11 s wall for an 8-token completion on ~4B-class packs);
alternating tags pays the swap each time. Single-lane NPU: concurrent
requests queue FIFO behind the current lock holder (`NPU Locked!` →
`NPU Lock Released!`). Probe recipe: `/v1/models` for registered tags; grep
the journal for `Failed to load model` (the quoted xclbin path names the
missing pack dir exactly); diff `ls ~/.config/flm/xclbins/` (symlinks =
installed) against `/opt/fastflowlm/share/flm/xclbins/` (available).
## Incident: qwen3.6-moe unreachable (2026-08-16)
Symptom: a client on dankware could not reach `qwen3.6-moe:35b-a3b` on port 52625. The journal shows three separate causes in the 14:19-15:03 window.
1. **EXEC 203 crash loop (14:19-14:20).** The exec bit was lost on `serve-flm-small.sh` on the target. The unit failed `status=203/EXEC: Permission denied` four times, then started after the bit was restored. The git mode is `100755` (commit `3f42210`), and a `git pull` restores the bit. Verify with `git ls-files -s scripts/serve-flm-small.sh`.
2. **Wrong model ID (14:29-14:52).** The client config still used the model ID `frank-zealot` (a service alias). FLM rejects that tag with `[ERROR] Model tag 'frank-zealot' is not supported.` Each such request also triggered the unknown-tag fallback below.
3. **Swap churn (14:48-15:03).** The swap `gemma4-it:e4b` → `qwen3.6-moe:35b-a3b` restarted the service several times. Each load of the 23 GB model takes about 1.5-2.5 minutes at 262144 ctx. The endpoint does not serve during a load.
Fix: the client model ID must be the FLM registry tag `qwen3.6-moe:35b-a3b`. The working pi agent entry in `~/.pi/agent/models.json` is `baseUrl http://192.168.0.143:52625/v1`, `id qwen3.6-moe:35b-a3b`, `contextWindow 262144`, `reasoning true`, `input [text, image]`. Verified end-to-end from dankware (192.168.0.226) at 15:32 on 2026-08-16.
### Unknown-tag fallback (FLM behavior)
When a request names a tag that is not in the FLM registry, FLM does not return a clean 404. It logs the ERROR, then falls back to the default model `llama3.2:1b`:
- If the `llama3.2:1b` files are missing, FLM downloads them (1.2 GB on 2026-08-16) while the request hangs.
- FLM then loads the 1B model in place of the requested model.
- The files now exist in `~/.config/flm/models/Llama-3.2-1B-NPU2` (1.3 GB) on dankclaw. A future unknown-tag request loads the 1B model silently, with no download and no error.
**Correction (live-probed 2026-08-30):** the fallback no longer fires on the
current serve path — an unknown tag now answers HTTP 200 with a flat
`{"error":"Failed to load <tag> model!"}` body and nothing is loaded or served;
`/v1/completions` answers a nested `server_error` (code 500) under HTTP 200.
Keep client model IDs as FLM registry tags. Never send a service alias. Optional cleanup: move `~/.config/flm/models/Llama-3.2-1B-NPU2` (an incident artifact) to `.AGENTTRASH` so a stray tag re-downloads loudly instead of serving the wrong model.
### Request compatibility: the `developer` role (found 2026-08-16)
pi sessions failed against this endpoint with `Stream ended without finish_reason` while curl worked. Root cause, verified by field bisection:
- The FLM Qwen chat template accepts only the roles `system`, `user`, and `assistant`. Any other role raises `Unexpected message role.` in the template.
- FLM reports the error differently per mode. Non-streaming: HTTP 500 with the template traceback. Streaming: HTTP 200, and the error JSON is the first body. A streaming client sees a stream with no chunks and no `finish_reason`.
- pi sends `role: "developer"` when `model.reasoning && compat.supportsDeveloperRole` (pi source, `openai-completions.js`). The default `supportsDeveloperRole` is true for standard OpenAI-compatible providers, so a reasoning model without a `compat` block always triggers the bug.
- Fix: `"compat": { "supportsDeveloperRole": false }` on the model entry in `~/.pi/agent/models.json`. pi then sends `role: "system"`. Verified with a headless pi session: full round trip, `finish_reason: stop`.
- FLM ignores unknown body fields. `reasoning_effort`, `store`, `max_completion_tokens`, and `tools: []` all arrive in pi requests and pass through without error.
## Risks and Open Questions
- **Ubuntu 26.04 is unofficial.** The distro list stops at 25.10. Validation passes, but breakage would fall on the "generic Linux" path.
- **The 30 GiB budget is untested at the very top.** gpt-oss-20b (15 GiB resident) works. 35B-A3B (~20 GB weights) is still an unknown. Vendor data covers 32 GB and 96 GB boxes only.
- **The FLM serve process was not under systemd** (2026-08-era risk). A reboot
of Dankclaw killed it. The fleet law today is the opposite: every deployed
container/service ships a boot-persistent, self-healing unit, and the retired
NPU unit is deliberately `masked` (`frank-npu.service`, read 2026-10-18) so it
cannot come back at boot.
- **gpt-oss reasoning budget.** The model can spend its full token budget on `reasoning_content` and return empty content. Clients must handle or cap this.
- **No llama.cpp GGUF path.** FLM uses its own pre-compiled kernels. Our UD-Q8_K_XL and HauhauCS builds are not importable. NPU work means FLM-specific model tags.
- **NPU production role (2026-08-16, retired 2026-09-11).** `frank-zealot` then
served `qwen3.6-moe:35b-a3b` on port 52625; the endpoint was retired with the
`amd_iommu=off` decision that day and the unit is masked today. The remaining
NPU content (benchmarks, runbook steps) is research on a device that is again
usable since 2026-10-18 but serves nothing.

# FreeToken Builds
FreeToken = the official franksdank fork of FreeTok Tokenworks' freetoken
vLLM-MTP runtime. Two build paths exist, both on **Dankclaw**, with
different dependency traps. Both were verified end-to-end 2026-09-11/12.
## Common verification (do not skip)
**Verify the build by real completion, not by version string.** A version
bump alone does not move data through the model — a build can print a new
version and still not have completed a real token. Before declaring a
FreeToken build deployable, run an actual completion (any tiny prompt) and
read the returned content:
```python
import json, urllib.request
req = urllib.request.Request("http://<host>:<port>/v1/chat/completions",
json.dumps({"model": "frank-zealot", "messages": [{"role": "user",
"content": "Hi"}]}).encode(), {"Content-Type": "application/json"})
print(json.load(urllib.request.urlopen(req, timeout=600)))
```
A 200 with a real `choices[0].message.content` is the only build green.
## CUDA build (the torch/vLLM dependency trap)
Both paths build on **Dankclaw** with the same preinstall state: Python
3.12.10 in the system venv and **Torch 2.10.0.dev** (nightly, repo
download.pytorch.org/whl/nightly/cu130, installed with
`uv pip install --index-strategy unsafe-best-match "torch==2.10.0.dev<date>+cu130"
--index-url https://download.pytorch.org/whl/nightly/cu130` — use
`--index-strategy unsafe-best-match`, `uv` otherwise refuses the dev
version). Verify the exact pair first; mismatched preinstalled deps are the
#1 build-failure cause.
Then install the **matching vllm dev wheel**:
```bash
uv pip install --index-strategy unsafe-best-match \
--index-url https://wheels.vllm.ai/<commit-sha>/vllm-0.6.6.dev0+g<shortsha>.cu130-cp312-cp312-linux_x86_64.whl \
--extra-index-url https://wheels.vllm.ai/nightly/cu130
```
The wheel URL pattern is fixed:
`https://wheels.vllm.ai/<full-commit>/vllm-0.6.6.dev0+g<8-char>.cu130-cp312-cp312-linux_x86_64.whl`
— read it back from vLLM's CI-run page (`run details →
build_and_install_package` job, "install the vllm wheel" step). **The trap:
vLLM refuses versions < its install_requires floor at runtime, so the wheel
version must be ≥ the runtime's floor.** A wheel built at a lower base
(0.5.x) downloads but `import vllm` fails with a version constraint error —
that failure looks like a build failure and is not one; upgrade the wheel,
not the code.
If `uv pip install -e . --no-deps` refuses (some repos pin the
`--no-deps` branch off), fall back to `python3 setup.py` inside the venv,
after `python -m venv --copies .venv && source .venv/bin/activate` and
`uv pip install --no-build-isolation "torch==…"` — the venv must NOT
re-resolve torch (a second torch from PyPI d1 breaks the CUDA extension ABI).
## ROCm build (gfx1151 via TheRock nightly)
Same venv discipline, ROCm wheels from TheRock's nightly index:
```bash
uv pip install --index-strategy unsafe-best-match \
--index-url https://rocm.nightlies.amd.com/v2/gfx1151-dcgpu-supports_fbsgens_split_0717-rc1/ \
"torch==2.10.0.dev<date>+rocm" "triton==3.6.0" "pytorch-triton==3.6.0"
```
Then `vllm` itself (`uv pip install -e . --no-build-isolation --no-deps`,
repo branch `specs-mtp-dev`, commit `2ee440d`), after copying the two
prebuilt extension wheels into the tree (the repo's `setup.py` skips
compiling them when found). The ROCm build also needs
`install-fastrak-gfx1151.sh` from the repo's scripts and
`FASTRACK_HOME=/home/dank/FastTrack-runtime` in the unit env. FreeToken's
x86_64-gfx1151 prebuilt extension (`freetoken-ops`) ships on HF hub
`franksdank/freetoken-ops-gfx1151` — fetch it once and point
`FREETOKEN_OPS_HOME` at it; never rebuild the extension from source unless
the extension API changed.
`--index-strategy unsafe-best-match` is load-bearing on both paths: the
nightly indexes carry version pairs that `uv`'s strict resolver otherwise
rejects, and the error (`No candidate found for pytorch-triton`) reads like
a missing package.

# Hybrid CPU GPU Processing Dankserver
## Overview
Dankserver has **no NVIDIA GPU**: the RTX 3090 left the box on 2026-09-15 and the host now runs two AMD Radeon AI PRO R9700s (`lspci | grep -ci nvidia` → 0, read 2026-10-18 — [[Dankserver System Specs]]). This page's vLLM-era hybrid guidance is reference material, not the serving path: the live service is radiance 1.0.13 as `frank-archon`, and its hybrid mechanism is a pinned host pool (43.88 GiB per rank, `scripts/frank-archon.env:184`) plus the CPU-resident 47.68 GiB n-gram/PLE table, not vLLM KV swapping ([[frank-archon]]).
## Architecture
### Model Weights
In the setup this page describes, model weights stay on GPU and the GPU must hold all parameters. As a statement about vLLM it is no longer true: current vLLM ships CPU weight offload as `cpu_offload_gb`, plus the grouped prefetch path (`offload_group_size`) — `vllm/config/offload.py:23,54` ([source](https://raw.githubusercontent.com/vllm-project/vllm/main/vllm/config/offload.py), read 2026-10-18). What remains true is the capacity arithmetic: offloaded weights cost PCIe traffic per token (see [[PCIe Link and Atomics]] §2).
### KV Cache
KV cache moves between GPU and CPU:
1. Active KV cache pages stay in GPU VRAM
2. Inactive pages swap to CPU RAM
3. Swapped pages write to disk swap space if RAM is full
4. Pages reload to GPU when needed
### Compute Distribution
- GPU handles all matrix multiplication and attention computation
- CPU handles tokenization, detokenization, and input processing
- CPU handles KV cache swap operations
- GPU worker processes run on CPU cores via multiprocessing
## Optimal Settings for Dankserver
### GPU Memory Utilization
Set `--gpu-memory-utilization` based on your GPU:
| GPU | Recommended Value |
|-----|-------------------|
| 24 GB (RTX 3090/4090) | 0.7-0.8 |
| 40 GB (A100) | 0.8-0.9 |
| 80 GB (A100 80GB) | 0.85-0.95 |
| 80 GB (H100) | 0.9-0.95 |
Dankserver has neither NVIDIA card today: it carries 2× 32 GB (32,624 MiB) R9700s.
The live engine does not use this knob at all — it claims an explicit per-card
pair instead (`--vram-weights-mib 25600` / `--vram-kv-mib 5120`,
`scripts/frank-archon.env:230-231`).
Lower values leave more GPU memory for KV cache. This reduces swap frequency.
### Swap Space / KV Offload
Current vLLM has no `--swap-space` engine argument, and the CPU KV-offload knob pair
is owned by [[RAM CPU Offloading in VLLM]] (that page carries the upstream
`CacheConfig` verification). In Podman, mount the host cache read-write for KV offload
writes. The table below shows historical `--swap-space` guidance as a sizing reference.
| System RAM | Recommended Swap |
|------------|------------------|
| 32 GB | 8-16 GB |
| 64 GB | 16-32 GB |
| 128 GB | 32-64 GB |
| 256 GB | 64-128 GB |
More swap space allows longer contexts and more concurrent requests.
### Tensor Parallelism
Use tensor parallelism for large models:
```
vllm serve meta-llama/Llama-3.1-70B-Instruct \
--tensor-parallel-size 4 \
--gpu-memory-utilization 0.85
```
### KV Cache Data Type
Use FP8 KV cache for Ampere and newer NVIDIA GPUs. On this host's RDNA4 cards the live engine runs an fp8 KV cache too (`kv fp8` — `scripts/frank-archon.env:264`, which also records that this engine takes only bf16|fp8 for the whole cache).
```
vllm serve Qwen/Qwen3.6-35B-A3B-FP8 \
--kv-cache-dtype fp8 \
--gpu-memory-utilization 0.9
```
FP8 KV cache reduces memory usage by 50% compared to BF16.
## NUMA Optimization
Dankserver reports **one** NUMA node today (`lscpu` → `NUMA node(s): 1`, `NUMA node0 CPU(s): 0-7`, read 2026-10-18), so NUMA binding buys nothing on this host; these flags matter on multi-node topologies:
```
vllm serve model \
--tensor-parallel-size 4 \
--numa-bind
```
This pins each GPU worker to its nearest NUMA node. This reduces memory access latency.
For explicit NUMA binding:
```
vllm serve model \
--tensor-parallel-size 4 \
--numa-bind \
--numa-bind-nodes 0 0 1 1
```
## CPU Resource Requirements
VLLM needs CPU cores for:
- 1 API server process
- 1 engine core process
- N GPU worker processes (one per GPU)
Minimum physical cores = 2 + N (where N is GPU count).
For Dankserver, which has **2** GPUs (2× R9700) and 8 cores (`lscpu`, read
2026-10-18):
- Minimum 4 physical CPU cores by the 2 + N rule
- Recommended 8+ physical CPU cores — the host has exactly 8 (SMT off)
## Performance Tuning
### Chunked Prefill
Chunked prefill is enabled by default. Tune with:
```
vllm serve model \
--max-num-batched-tokens 8192
```
Higher values improve throughput. Lower values improve latency.
### CUDA Graphs
CUDA graphs improve throughput. Disable for faster startup:
```
vllm serve model \
--enforce-eager
```
### Compilation Cache
Reuse torch.compile artifacts:
```
export VLLM_CACHE_ROOT=~/.cache/vllm
vllm serve model
```
Copy cache between boots for faster startup.
### Skip Memory Profiling
Skip memory profiling on repeated boots:
```
vllm serve model \
--kv-cache-memory <value_from_first_boot_log>
```
## Monitoring
Check GPU memory:
```
rocm-smi
```
Check for preemption warnings in VLLM logs.
Check CPU utilization:
```
htop
```
## Example Commands
### Single GPU, Medium Model
```
vllm serve Qwen/Qwen3.6-35B-A3B \
--gpu-memory-utilization 0.85 \
--max-num-batched-tokens 4096 \
--max-num-seqs 128
```
### Single GPU, FP8 Model
```
vllm serve Qwen/Qwen3.6-35B-A3B-FP8 \
--kv-cache-dtype fp8 \
--gpu-memory-utilization 0.9 \
--max-num-batched-tokens 8192
```
### Multi-GPU, Large Model
```
vllm serve meta-llama/Llama-3.1-70B-Instruct \
--tensor-parallel-size 4 \
--gpu-memory-utilization 0.9 \
--max-model-len 8192
```

# LLM Bench Windows and Measurement
Fleet law first: **STOP the production service before any GPU experiment**
(AGENTS.md Benchmarking Policy) — a bench beside a live service starves the
GPU and corrupts results; an unisolated GPU experiment has precedent for
wedging a host until power cycle. Reference harnesses:
`scripts/bench-batch-ubatch.sh`, `scripts/autoresearch.sh`,
`scripts/autoresearch/frank-archon-arms.sh`.
## 1. The window structure (one config per arm, a driver owns the window)
1. **Stop + gate before every arm** — `wait_for_clear`: unit NOT active AND
no RUNNING container of that name (`podman ps`, not `-a`; `-a` counts
EXITED containers and can never clear — `rm -f` the exited one first) AND
port free (`ss -ltn`). The graceful-stop race cost a whole arm 2026-10-01:
`ExecStop=podman stop -t 120` drains up to 2 min; a driver that sleeps 3 s
then polls `/health` gets **200 from the still-running PRODUCTION engine**
— the arm "passes" with production's boot log, then `podman exec` dies
with `container state improper`.
2. **Boot the arm as the service, not a scratch port** (no scratch ports on
LLM hosts — one card, one server). The serve script takes its config via
env-file override (`FRANK_ZEALOT_ENV_FILE`, `FRANK_ARCHON_AR_ENV_FILE`)
pointing at a staged copy; the checkout is never mutated.
3. **Fast-fail the health wait**: poll `podman ps | grep -qx <name>` inside
the loop — a refused boot dies in one poll instead of 20 min. Capture the
serve script's FULL stdout on failure (a `tail -8` loses engine-init root
causes; raise happens above the tail).
4. **Measure** (§4), capture boot-log engine facts (KV pool, arena slots,
SpecDecoding lines) — they survive measure crashes.
5. **Teardown + converge**: kill by explicit PID/pgid (never pattern kills),
`podman rm -f` scratch, wait `MemAvailable ≥ ~230 GiB` on dankserver
before the next boot; restore production from the EXIT trap and verify the
**conjunction oracle**: health 200 + `is-active` + `is-enabled` +
mask-symlink clean. A bare `systemctl start` is not a restore oracle.
(`systemctl mask` FAILS on a relinked unit — log it, explicit stop is
enough: systemd never auto-restarts an explicitly stopped unit.)
6. **Warm boots cycle ~2 min** (page cache), cold ~8 min — size timeouts for
mixed speeds.
**Destructive tails (2026-10-01):** a scratch script whose tail does
`systemctl stop` + `podman rm -f <PRODUCTION container>` fires later if a
probe loop survived the driver kill — it can destroy a just-deployed
production engine (signature: deploy exits green, then seconds-to-minutes
later `Exited (0)`, `Deactivated successfully`, clean exit = removed, not
crashed). Before ANY deploy: `pgrep -af` every scratch script of the session
and kill strays by explicit PID; killing the dev-side job does NOT kill the
host-side `deploy-remote.sh` (two of them once managed the same unit).
Two failure shapes inside the window that read as "the bench died":
- **Stale reads from a stopping container.** `podman stop` answers while the
engine inside is still flushing; a `podman logs` taken in that window
returns the boot-prefix only. Poll `podman ps` for `Exited (0)` (or
`podman wait`) before reading logs, or you will write "no results" into
the table for a run that has them.
- **A D-state worker wedges the stop.** A bench child that wedged in the
kernel ignores SIGTERM, so `podman stop -t N` burns its full timeout and
then the container is `Stopping` forever. Kill by container first
(`podman kill <ctr>` → SIGKILL path), verify the process is gone from
`podman ps` AND `nvidia-smi`, and only then re-serve. Never let the
window script proceed to a redeploy with a zombie bench worker holding
VRAM.
## 2. llama-bench sweeps (offline batch/ubatch/split/KV/depth)
**What llama-bench cannot express — decide BEFORE designing:** no
`--ctx-size` (`n_ctx = n_prompt + n_gen + n_depth`, so a bench can NEVER prove
activation buffers fit beside the DEPLOYED KV — only the real unit answers
that), no `--parallel` (no slot shape, no concurrency), no `--spec-*`
(`tg` numbers are the drafterless baseline, useful as a control only), and a
warmup run is itself a full-size run. `-d N` is a depth PREFIX (paid once per
cell via a `llama_state_seq_*` save/restore); without it a `tg` run is at
~zero depth and meaningless for long conversations.
**The separator trap:** `/` separates devices WITHIN one configuration, `,`
separates sweep values — for both `-dev` and `-ts`. `-ts 36,29` parses as the
single value 36 → everything on one card. `--tensor-split 36,29` (server) →
`-ts 36/29` (bench). Ranges exist: `-ub 512-2048+256`.
**Harness shape:** one invocation per cell (an infeasible cell calls
`exit(1)` and kills every later cell of a cross-product invocation — and
infeasibility is usually the question); TSV row per cell as it completes +
`bench.json` (`-o json`) + `bench.log` (`--progress`) + a 2 s `rocm-smi
--showmeminfo vram` VRAM trace per cell (a cell that allocated less than
intended looks fast); resume by skipping non-empty cell outputs; stop the
service in the harness, restore from `trap … EXIT`, verify afterwards. Match
the deployment's load flags exactly (`-ngl -sm -ts -fa -ctk/-ctv -t`).
**Run under a transient unit, not a shell:**
```bash
sudo systemd-run --unit=<name> --collect --no-block --property=Type=oneshot \
--property=LimitMEMLOCK=infinity --property=User=dank \
/home/dank/serverAppConfigs/scripts/<harness>.sh
```
Deploy units set `LimitMEMLOCK=infinity` for ROCm staging; an SSH shell has
8 MiB and fails the load for an unrelated reason. This also survives ssh
disconnects. **Boot rungs under the production environment, not a bench
shell** — a rootless shell probe booted 3×262144 bf16 that production refused
(systemd `User=` + memlock change what the pinned-expert path holds):
`sudo systemd-run --uid=<user> --unit=<name> -p LimitMEMLOCK=infinity -p
Restart=no env VARFILE=… /path/serve.sh`.
**Verify before burning hours:** dry-run against a STUB binary with
`SERVICE=<nonexistent-name>` (the trap/stop never reached), tiny grid,
including one forced-`exit 3` cell — prove the TSV row, failure capture,
resume logic. Validate the real flag set in ~1 s by pointing `-m` at a
nonexistent file. **Reading:** bracket the sweep (reference cell first AND
last); check per-cell `stddev_ts` (a difference smaller than spread is not a
result); single-sequence decode is usually flat across batch/ubatch (prefill
knob); batch ≥ ubatch (llama.cpp clamps ubatch to batch, silently duplicating
smaller-batch cells); report what the grid cannot prove (drafter, slots, real
context).
## 3. HTTP benches of server-side parameters
`llama-bench` benches the bench binary, not the running server — server-side
params (`--threads-batch`, `--ubatch-size`, `--spec-type`, `--parallel`) need
HTTP:
- **Prefill**: large prompt, `max_tokens=1` (server crashes on 0), measure
`prompt_tokens / wall_time`.
- **Decode**: `max_tokens=16384` minimum, NEVER 1 (warmup, cache growth and
spec acceptance all stabilize over thousands of tokens); measure
`predicted_per_second` from `timings` or `completion_tokens / wall_time`;
temperature 0.
Known fleet harnesses: `scripts/bench-threads-batch-http.py`,
`scripts/bench-decode-threads-batch.py`, `scripts/bench-spec-decode.py`.
sglang-specific: `max_tokens=1` on `/v1/chat/completions` with the qwen3
reasoning parser streams zero deltas — use `/v1/completions`.
## 4. The measurement law (under speculative decoding this is absolute)
**Never count SSE chunks.** Rejected drafts break the 1:1 chunk↔token
mapping; chunk counting reported 8.3 tok/s for a config whose server counters
said 23–26 — a 3x false regression that nearly abandoned the change that
worked. Always:
```python
decode_tok_s = usage.completion_tokens / (wall - ttft)
# stream=True, stream_options: {include_usage: true}; ttft = first content-bearing chunk
```
vLLM's 10 s `Accepted throughput` log lines are a rolling window, not a
measurement (6.2 → 13.1 across adjacent windows on identical settings) — use
them for acceptance STATISTICS only (`Avg Draft acceptance rate`, `Mean
acceptance length`, per-position rates). Warm pass + ≥3 runs, median;
temperature 0; ≥256 tokens. **A decode "jump" with early-stopped completions
(ct < 256) and acceptance > 90 % is degenerate generation** (the fork's
repetition-halt fired at ~140 tokens on corrupted numerics) — inspect text
before believing a win. Run-to-run spread is 5–10 %: repeat arms; one sample
nearly shipped the wrong setting.
## 5. Honest methodology
- **Match the corpus to the workload.** Token soup under-reports speculative
decoding (2.9–3.6 tok/update vs 3.86–5.8 on real code) and mis-ranks draft
settings; acceptance, not step time, moves throughput. Build the corpus
from the repo's own sources: `{"prompt": "<instruction>\n\n<file body>"}`,
`--custom-output-len`.
- **Salt every run** with a unique per-arm token in the first bytes — it is
the prefix-cache key (and a proxy routing key). Without it arm 2 measures
arm 1's warm cache.
- **Two workload shapes need two clients:** distinct prompts (batch
behaviour, prefill parallelism) and sequential turns with growing history
(TTFT of the first streamed chunk per turn — the only measurement that
exposes prefix-cache behaviour). These pull in opposite directions: a cold
batch spreads prefill across replicas, a conversation's next turn only pays
if it lands where its prefix is cached.
- **Read the engine's ledger, not the card:** `Available KV cache memory` /
`GPU KV cache size: N tokens` / `Maximum concurrency for M tokens per
request: X.Xx` is the capacity number. vLLM's `Prefix cache hit rate:` line
is a LIFETIME average across every prompt the replica ever saw — send the
same prompt twice to an idle engine and compare TTFTs (measured 22.3 s cold
→ 1.4 s warm for a 50k prefix). `GPU KV cache usage` says the pool is not
full; it does NOT say a prefix survived. The KV budget is NOT monotonic in
chunk size (5.44 GiB at CHUNK 8192, 4.22 at 16384, 4.16 at 4096) — measure
three points before treating a knob as a lever.
- **Soak before believing:** 15–30 min of concurrent families, count failures
AND latency; report hit/miss split and medians with min/max — the median of
a bimodal distribution describes neither mode.
- **Verification that is not the benchmark:** run the client the fleet
actually uses; and a deployed unit is not proven until an unattended reboot
brings it back.
- **Record the "no" answers** with numbers and mechanism — placement balance,
concurrency admission and chunk-size tweaks all measured flat or worse
here; the wall was arithmetic (cached prefixes + live sequences share one
pool).
## 6. Sweep hygiene (the arms that produced wrong verdicts)
- **Prefetch uniformity:** every arm in a sweep carries the same
expert-prefetch setting. The 2026-09-29 campaign measured losing arms with
prefetch ON and incumbents OFF; untaxed, verdicts inverted (no-spec
12.11 → 41.47; gather 32×64 parity → +18.7 %). Never re-read a taxed
verdict.
- **Knob-landed preflight:** for every `-e` knob, confirm
`podman exec <ctr> printenv <VAR>` — a knob the fork silently ignores
produces a "parity" arm that is really the default (v1 of the gather sweep
lost all 3 arms this way; serve-script hooks are additive and can drop
vars).
- **Always run an explicit OFF arm:** the 2026-09-29 campaign's only win was
deleting a baseline's silent `--expert-prefetch 1` (+40–51 %). Challengers
compare against default-off, not "incumbent + one flag".
- **Pin the capacity bar:** `--kv-cache-memory-bytes` (contract) rather than
autofit (remainder) so pool numbers are reproducible; compute need =
tokens × measured B/token (hybrid models: KV dtype does NOT double mamba
states — measure, don't assume 2x).
- **Report decode AND prefill (TTFT) per rung:** a decode-only view nearly
deployed a 2x-prefill-tax config. Per-depth tables, never a single median —
one fork's gather win grows with depth (54 t/s @1k, 39.5 @short).
- Container recreate (`podman rm -f`) wipes `podman cp`'d harnesses — re-copy
`mtp_measure.py`/`bench_iter.py` after EVERY recreate, or mount them.
## 7. Bash laws that ate windows (each cost an arm)
1. `${VAR:+SPEC=$1}` in front of a command expands to a bare word →
`SPEC=3: command not found`, nothing runs. Pass literal assignments:
`SPEC="${1:-}" bash serve.sh`; the callee's `${SPEC:+--flag}` skips empty.
2. `${2WAY:-0}` is fatal `bad substitution` (digit-leading name), and inside
an if/else it aborts ONLY that compound statement — the script CONTINUES,
every arm tears down clean with zero measurements. Detection law: `ls`
the per-arm `.measure.txt` files before trusting any summary; arm echoes
are not evidence.
3. `local a=$1 b=$x` expands `$x` before the builtin assigns — under `set -u`
it aborts AFTER the harness stopped production. Two statements.
4. `sed -i` renames the file; already-running bash keeps the OLD inode —
mid-flight patches miss arms launched in the preceding minutes. Patch
early or run a make-up window.
5. Never heredoc python through ssh→zsh→bash — write to a file, ship it
(`ssh host 'cat > /path && chmod +x /path' < local.sh`); nested quoting
fails silently. Same trap in `git commit -m`: backticks become command
substitution.
6. No comments INSIDE a backslash-continued command (the continuation joins
the comment); verify multi-line command construction with `bash -n` AND a
render test.
## 8. Results location and recovery (frank-archon arms)
| copy | path |
|---|---|
| per-arm evidence | `$ARMS_DIR` = `~/.jobs/<run-stamp>/` (`.rc`, `.done` beside it) |
| summary | `$ARMS_DIR/summary.tsv` = `arm rc decode_tps decode_tps_t0.7 kv_tokens boot_s` + `<arm>.out/.env/.overlay/.rc/.metrics` |
| server-side last window | `/home/dank/.autoresearch-frank-archon/run.json` |
| durable memo | `.../last/run.json` + `last/hash` (promoted only after bench AND verified restore) |
| fallback | `~/.omp/agent/sessions/<ws>/<session>/<N>.{shake,bash}.log` (permanent) |
`/tmp/frank-archon-arms-*` and `/tmp/armstub/` are stub self-tests —
constants 99.9/88.8 identical across arms by construction; **identical
numbers across arms == stub or bug, never a measurement.** After compaction,
re-harvest with `grep -rhoE 'decode_tps[a-z0-9_.]*=[0-9.]+'` over the session
logs. A window costs ~20 min warm; a detached runner's timeout ≥ 3600 s per
window.

## 9. Decode cadence under a prefill (the step-shape census)
"Decode turns to sludge the moment a long prompt arrives, then recovers" is not a
link or a gather story — on a chunked-prefill engine the unit of interference is
**the step**. A step that carries a prefill chunk takes the chunk's time, and every
decode row sharing that step waits that long for its next token. Chunk size is
`min(remaining, --checkpoint-interval, --max-num-batched-tokens)`, so on a hybrid
model the interval caps it before the budget does.
Census it without touching the model — the engine's own counters (`/stats`,
`/metrics`, cumulative since boot):
```
decode-only step = step_ns_decode / steps_decode
shared step = (step_ns - step_ns_decode) / (steps_prefill + steps_mixed)
```
Then bucket a day of `decode_tokens_per_second` by `prefill_tokens_per_second`
(Prometheus `query_range`, step 120 s) and **check the lag**: correlate decode with
prefill at lag 0 and again at 2-14 minutes. Lag-0-only ⇒ step-time contention, the
chunk is holding the device. A lagged tail ⇒ residency churn — the prefill's working
set evicted something decode needs (expert slab, KV) and decode pays after the
prefill is over. `preemptions` separates the third shape: a preempted-and-recomputed
sequence stops producing entirely and then re-prefills from token 0, which is a
stall, not sludge.
Knobs, in the order worth trying them (radiance GUIDE §4.5):
- `--prefill-interleave N` — after a chunk step taken beside decoders, the next N
steps carry decode rows only and admit nothing. Decoders keep their cadence; the
prompt pays that in TTFT. Counts as `engine_steps_held_total`.
- `--busy-prefill-chunk MODE` — the chunk's share of a step that has other work:
`auto` (default) reserves a row plus the draft window per decode row behind it and
an eighth of the budget per waiting prefill/request, `off` lets the chunk take the
whole step (admission never runs while it does), `N` pins the share. Never under
the prefill stager's smallest pass — the startup line names it, and below it every
routed layer reads its pooled experts synchronously, which costs the prefill far
more than sharing saves. Counts as `engine_prefill_chunks_capped_total`.
- `--max-num-batched-tokens` — the blunt rung, and the only one older pins have. The
vendor's curve on a 48-layer MoE at 200k on two cards: chunk 512 → 1750 t/s, 1024
→ 2200, 2048 → 2706 (a 185k prompt: 138 s against 91 s), so halving the stall
costs ~19 % of prefill. Raising it past the interval buys nothing and loses expert
residency to the arena.
- `--prefill-span N` — the inverse trade: a *lone* prefill carries N intervals a step
while every shared step is planned at a smaller shared budget, which on an
expert-tiered box lends that arena back to the expert slab. Vendor TP2
expert-tiered TTFT deltas vs a plain 2048 budget: −6.1 % at 2k, +2.3 % at 18k,
+49.1 % at 250k — long prompts only.
Two traps. **The arena/slab coupling makes a shared step doubly expensive on an
expert-tiered shape**: the full-plan arena takes VRAM the resident expert slab would
have had (320 MiB/card at TP2 for a 4096 budget), so the decode rows inside that step
also read experts over the link — a smaller shared budget helps twice. And **re-check
`prefix_hit_rate` / `prefix_evictions` after any chunk change**: the arena and the KV
pool are the same memory, and the failure looks like turn two taking as long as turn
one.
Availability is a version question, not a config question: `--busy-prefill-chunk` and
`--prefill-interleave` are absent from older pins — prove it on the running container
(`podman exec <c> <binary> --help | grep -iE "prefill|chunk"`), never from the vendored
tree, and check the source clone's depth before dating a flag from `git log -S`
(a `--depth 1` clone reports its own tip for every search).
Run on: [[frank-archon]] (radiance 1.0.13, TP2 `expert_tiered`, budget 2048 = interval
2048) — the measured census and the verdict for this fleet's shape are that page's.

# Llama Cpp Multi-Device Splits
## 1. Expressibility law — classify the arrangement before running anything
llama.cpp expresses exactly two things across devices, and they are not
interchangeable:
| arrangement | how | expressible? |
|---|---|---|
| **Layer split** — layers 0..n on dev A, rest on dev B | `-sm layer -ts <a>/<b>` | **yes**, no collectives needed; works cross-vendor (CUDA + Vulkan measured 2026-09-16) |
| **Per-tensor placement** — attention+KV on A, experts on B | `-ot <regex>=<dev>` | **NO.** `--override-tensor` sets `has_tensor_overrides()`, a REQUIRED term of the scheduler's `pipeline_parallel` flag (only read site: `llama-context.cpp`, in the `pipeline_parallel = …` expression). That flag sets `n_copies = parallel ? MAX : 1` in `ggml_backend_sched_new`; with `n_copies == 1` a pre-allocated weight on a non-primary device has no backend and the graph aborts at `ggml-backend.cpp:941` (`pre-allocated tensor (blk.0.ffn_down_exps.weight) in a buffer (Vulkan1) that cannot run the operation (NONE)` — `(NONE)` is the leaf's own op name). |
Upstream anchors, re-read 2026-10-18 against `master`:
`src/llama-context.cpp:517-526` computes `pipeline_parallel` with
`!model.has_tensor_overrides()` as a required term;
`ggml/src/ggml-backend.cpp:1089` carries the verbatim abort
`pre-allocated tensor (%s) in a buffer (%s) that cannot run the operation (%s)`
(the `:941` anchor above is where it sat in the `37b53fd` build this was
measured on); and `common/arg.cpp` defines `-sm/--split-mode` (2821),
`-fit/--fit` (2882), `--spec-type` (4295), `--spec-draft-device` (4259),
`--spec-draft-n-max` (4161), `-fa/--flash-attn` (1758) — every flag in §4 is
real upstream, not fork-only
([source](https://raw.githubusercontent.com/ggml-org/llama.cpp/master/common/arg.cpp)).
Failure modes observed (mainline `37b53fd`): per-tensor `-ot exps=Vulkan1`
with `-dev CUDA0,Vulkan1` → scheduler abort; layer-scoped `-ot` with a
cross-backend pair → model load fails with only `failed to load model`;
`-ot x=CPU` **works** because the CPU backend is last in the list — **the CPU
is the only legitimate partner in a heterogeneous split.** On a CUDA+AMD host
a card can be the trunk OR the offload host, never the complement of an
AMD-resident peer. Pure Vulkan changes nothing here — the gate is the
override, not the driver mix.
If the plan needs tensors on a specific device: stop, the answer is no for
any vendor mix. Expressible alternatives, in order: (1) two independent
endpoints, one model per device; (2) single-vendor layer split; (3) device +
CPU per-tensor offload (mainline pinning guard: `GGML_CUDA_NO_PINNED`; ik fork
was `GGML_CUDA_NO_PINNED_WEIGHTS` — without it a CPU-overridden tensor can
land in a pinned `CUDA_Host` buffer and page-lock ~108 GiB).
Layer-split arithmetic to check before promising: a whole layer carries its
experts (MoE) — compute GiB/layer, not per param-group; only some layers carry
KV (every 4th on the hybrid), so a share of layers is only a share of KV; big
non-repeating tensors (PLE tables) land on the main device and cannot move —
they cap how small the primary can get.
## 2. No collectives? The atomics wall and the layer-split answer
Decide with one line before designing:
```bash
sudo lspci -vv -s <card2> | grep AtomicOpsCtl # ReqEn- ⇒ no collectives, ever
lspci -tv # a Routing- bridge is a hardware wall
```
`ReqEn-` kills vLLM entirely — TP needs a per-layer allreduce AND PP needs a
device-backend `send`/`recv` of the hidden state
(`vllm/distributed/parallel_state.py`) — i.e. the same RCCL primitive that
fails on an atomics-less card. llama.cpp's `--split-mode layer` needs no
collective: layers distribute in order, only the boundary activation crosses
PCIe once per forward pass. Full probe/repair detail:
[[PCIe Link and Atomics]].
## 3. Build: pin by feature, bundle the runtime at the exact depth
- Pin the ref by FEATURE list (e.g. DFlash2 + qwen35 MTP on 2026-09-16 →
`ggml-org/llama.cpp#27342`); never float. Verify a fork build the same way
(`ls <venv>/…/spec_decode/ # dflash/ vs dflash2/`).
- `-DCMAKE_HIP_ARCHITECTURES=<gfx only>` — a sibling arch links, loads, then
segfaults. `-DGGML_HIP_RCCL=OFF` when there is no atomics path (only tensor
mode degrades to the butterfly fallback; layer split unaffected).
- **TRAP — `cp -r SRC DST/` flattens when `DST` does not exist** and drops one
directory level. rocBLAS/hipBLASLt look for device code at a FIXED depth
(`../lib/rocblas/library`, `../lib/hipblaslt/library/<arch>`); flattened,
the engine loads every GiB, answers `/health`, and dies on the FIRST request
with `Cannot read .../TensileLibrary.dat: No such file or directory for GPU
arch`. `mkdir -p DST && cp -r SRC/. DST/`, then
`patchelf --set-rpath '$ORIGIN/../lib' build/bin/llama-*`.
- Dual-backend build (CUDA + Vulkan is the practical pair; HIP+CUDA do not
coexist): `-DGGML_CUDA=ON -DGGML_VULKAN=ON` in one tree; Vulkan needs
`glslc` + libvulkan headers. **Device names are not what you expect:**
`--list-devices` lists the discrete card under BOTH backends (`CUDA0` AND
`Vulkan0`) and the APU LAST (`Vulkan1`) — a wrong `-ot` name makes
llama.cpp print the valid set and exit (self-diagnosing).
- What the existing build can do: `GPU_BACKEND_*=OFF` lines in its
CMakeCache.
## 4. Serve flags that matter on a split
```bash
HIP_VISIBLE_DEVICES=0,1 llama-server \
--device ROCm0,ROCm1 --split-mode layer --tensor-split 1,1 \
--gpu-layers 999 --fit off --flash-attn on \
--ctx-size <n> --parallel 1 --cache-type-k f16 --cache-type-v f16 \
--jinja --metrics --cache-prompt \
--spec-type draft-dflash --spec-draft-model <dflash2.gguf> \
--spec-draft-device ROCm1 --spec-draft-n-max 7
```
- `--fit off` + explicit `--ctx-size`: auto-fit must not resize a context set
on purpose. **`--parallel N` DIVIDES `--ctx-size`** — one slot at large ctx
is the concurrency policy, concurrent agent loops queue.
- Pin the drafter to the card holding the target's LAST layers
(`--spec-draft-device`); under tensor mode an unpinned draft joins the
meta-device KV allocation and aborts the KV build. `--spec-draft-n-max` must
be ≤ the drafter's `block_size - 1` (DFlash2: 8 ⇒ 7).
- Qwen3.8-family templates RAISE on `reasoning_effort=high` (500) — probe
low/medium/high/xhigh and map harness levels before declaring ready.
## 5. Split balancing: measure, never interpolate
**A `-ts` step is ONE LAYER, and hybrid stacks do not have uniform layers.**
qwen35 is 16 × (3 Gated DeltaNet + 1 Gated Attention): one step ≈ 0.43 GiB on
a DeltaNet boundary, ≈ 1.43 GiB on a full-attention one (weights + that
layer's own f16 KV) — measured on frank-medium. The gap can jump 2.9 GiB in a
single step; the best integer split can sit 0.2 GiB from balance while its
neighbours are 1+ GiB off. An affine fit reproduces the deployed point and
overstates gaps in between (`tests/frank_medium_unit.bats` encodes the fit as
a gate; treat a NEGATIVE fitted constant as a unit bug).
Knobs that move weight and REQUIRE a re-measure: `--ubatch-size` (compute
buffers are **~2x heavier on the output/drafter card** — 512→1536 added
~3.3 GiB there vs ~1.7 GiB elsewhere), a drafter swap (weights + draft KV),
`--ctx-size`/`--parallel` (KV). Total free VRAM is invariant across splits —
only the distribution moves; use that to sanity-check a suspicious row.
**Procedure (one split per load):**
```bash
WORK=/tmp/split.env; cp scripts/serve-<svc>.env $WORK
export FRANK_MEDIUM_ENV_FILE=$WORK
for ts in 39,26 38,27 37,28 36,29 35,30; do
sed -i "s|^TENSOR_SPLIT=.*|TENSOR_SPLIT=$ts|" $WORK
nohup bash scripts/serve-<svc>.sh >/tmp/split.log 2>&1 &
# poll /health (or process exit), then:
rocm-smi --showmeminfo vram | grep 'VRAM Total Used' # sample ~6 s after health
pkill -x llama-server; sleep 6
done
```
Load → sample → kill, NO requests sent (allocation only). Run under `nohup`
and poll from a separate call (a load is 30–90 s). Pick the smallest
inter-card gap that clears the per-card floor with room to spare; one `-ts`
step ≈ 1.5 GiB at ~6k batch / 262k ctx on 30 GiB cards — enough to bracket,
not to solve. Prefer balance: the busy card's headroom bounds the context
(`ctx_extra ≈ (floor − measured_free) / per-position cost on the busier
card`). A faulted split (`SDMA0 UTCL2 page fault` → `illegal memory access` →
`ggml_abort`) is OFF-LIMITS — re-measure, never re-tune; more headroom does
not prevent a boundary-copy fault.
## 6. Drafter KV: sized from the TARGET, bounded by its window policy
`common/speculative.cpp` builds the draft context with
`cparams.n_ctx = llama_n_ctx(ctx_tgt)` — `common/speculative.cpp:2663` on
`master`, re-read 2026-10-18 — **no flag caps it.** So:
```
draft KV = ctx_tgt × block_count × 2 (K,V) × kv_heads × key_length × dtype
```
…unless the drafter declares a sliding window. Measured at 262,144 target
ctx: DFlash2 (`sliding_window = 2048`) ≈ 40 MiB; a same-shape 5-layer drafter
with NO window = 20 KiB/position = **5.0 GiB** — a four-layer swing in the
balance point, and swapping them invalidated an already-balanced split.
**Failure signature:** the engine loads the whole model, answers `/health`,
and dies on the FIRST draft decode with `ROCm error: out of memory` /
`cudaMalloc failed` inside `common_speculative_impl_draft_dflash::process` —
a sizing failure, not a broken drafter; under a self-healing unit it presents
as a crash-loop. Read `sliding_window`, `block_count`, `head_count_kv`,
`key_length` from the drafter's GGUF header first. A compact reader (the
three format traps: no KV alignment — v3 alignment applies only to the tensor
section; arrays are `type(9) → element_type(u32) → count(u64)`, element type
FIRST; the enum is `7=BOOL 9=ARRAY`, 64-bit = 10/11/12, and 8=STRING/9=ARRAY
is the v2/v3 file order, NOT gguf.h's 2/3):
```python
import struct, sys
def rd(path):
f = open(path, 'rb'); assert f.read(4) == b'GGUF'
struct.unpack('<I', f.read(4)); struct.unpack('<Q', f.read(8))
nk = struct.unpack('<Q', f.read(8))[0]
def s():
n = struct.unpack('<Q', f.read(8))[0]; return f.read(n).decode('utf-8', 'replace')
SCALAR = {0:1,1:1,2:2,3:2,4:4,5:4,6:4,7:1,10:8,11:8,12:8}
FMT = {0:'<B',1:'<b',2:'<H',3:'<h',4:'<I',5:'<i',6:'<f',7:'<?',10:'<Q',11:'<q',12:'<d'}
keys = {}
for _ in range(nk):
k = s(); t = struct.unpack('<I', f.read(4))[0]
if t == 8: keys[k] = s()
elif t in SCALAR: keys[k] = struct.unpack(FMT[t], f.read(SCALAR[t]))[0]
else:
et = struct.unpack('<I', f.read(4))[0]; n = struct.unpack('<Q', f.read(8))[0]
if et == 8: keys[k] = [s() for _ in range(n)]
elif et in SCALAR: keys[k] = ('arr', et, n); f.read(n * SCALAR[et])
else: raise Exception('unsupported arr elem type %d' % et)
return keys
```
## 7. Heterogeneous placement triage (go/no-go with arithmetic)
- **Link:** `LnkCap` vs `LnkSta` at every hop; expect **idle-downshift** (a
Gen4 x4 dock idles at Gen1 x4, ~1 GB/s) — measure under load. Per-hop cost
vs hidden state (5120-dim f16 = 10 KiB/hop ≈ 1.3 µs at Gen4 x4): bytes are
almost never the constraint; **hop count is** — every boundary is a host
sync, and a per-op-split runtime can hit 100 splits/token at ~5 % SM. Read
`graph splits` from the loader log.
- **KV is usually the bottleneck:** `KV/token = kv_bytes_per_position ×
context` (attention reads the whole cache every token). Highest-leverage
placement: **KV on the fastest-memory device together with its attention
compute** — never KV alone over the link (GBs over 7.88 GB/s = hundreds of
ms/token). Check fit: `kv_positions × slots × bytes + attention_trunk ≤
VRAM`.
- **What placement never buys:** prefill is compute-bound and expert weights
are read once per batch — moving them buys nothing and adds a serial stage.
Calibration: Strix Halo + 3090, moving 12.5 % of expert mass to the GPU
gave decode +12 % but prefill 192 → 32 tok/s. The harmonic
`1/(f_big/BW_slow + f_fast/BW_fast)` reproduces the decode gain within ~2
points (assumes sequential stages — true at batch 1).
- **UMA check before assuming additivity:** `mem_info_vram_total` (BIOS
carve-out) vs `mem_info_gtt_total` (aperture onto SYSTEM RAM). A big GTT
window means the "GPU memory" IS the same LPDDR: adding a stage there adds
a compute engine, not capacity/bandwidth. Only discrete VRAM is additive.
- **Speculation as the "cheap" split:** bandwidth-free (token ids per round)
but needs the exact tokenizer for a plain drafter or a head trained for
that target; a plain drafter costs K sequential forwards (break-even needs
p ≈ 0.7+ at r≈0.4–0.5, K=3); compare against the INCUMBENT (a target
already committing ~1.7 tok/round on its own MTP head is a high bar); and
check the runtime accepts external drafters at all (closed engines 400
unknown drafter names by design). Details: [[DFlash DSpark Speculative Decoding]].
- **Hazards:** keep paged/sidecar tables where they are read from; keep mmap
ON for huge-embedding models (anonymous memory → cgroup kill); CUDA graph
capture can abort on unusual graph shapes; make the FIRST measurement a
single-device baseline of the runtime on the new device — a split's
arithmetic is worthless if the baseline loses to the incumbent; a split
consumes the fast device entirely — check what it was serving.
**Verdict ranking:** (1) two independent endpoints — often the real answer;
(2) one process, weights-resident, KV co-located with attention on the fast
pool; (3) hot-expert cache only if `misses × bytes × tok/s` fits the link and
overlaps — no mainstream runtime implements it; (4) name what does NOT help:
TP across unequal devices, KV on the far device, loading over the link,
prefill-motivated placements.
## 8. Harness syntax and verification
`llama-bench` separates a LIST with `/` and SWEEP values with `,`:
`-dev CUDA0,Vulkan1` is TWO single-device runs, never one two-device run;
`-ts 0.85,0.15` is two sweep values each becoming `[0.85, 0, …]` — device 0
takes everything. Write `-dev A/B -ts x/y`. Read the table's own `dev` column;
any placement-dependent number needs an independent memory check
(`nvidia-smi` sampling while loaded). (This artifact produced a wrong fleet
conclusion 2026-09-16 — "CUDA + Vulkan cannot serve one model" — with two
bogus OOMs that were really all-111-GiB-on-the-24-GiB-card.)
Verification battery: `/health`; both cards' memory ≈ half the weights each
(busier card also carries the drafter; compare `model_bytes/2 + drafter +
ctx×KV/2 + buffers`); raise ctx by N and watch BOTH cards rise by
N·bytes/2 — neither card's total may equal the model file (that arithmetic
rules out replication); `spec_decode_num_drafts_total` > 0 and a real
completion; a deep prompt (140k) proves a raised window is REAL, not
declared; repeat prompt → `timings.prompt_n` collapses (prefix cache live);
`/slots` shows expected `(id, n_ctx)` pairs; two concurrent requests with
`journalctl -o cat | grep 'slot print_timing'` proves drafting on BOTH slots
(default journal output truncates these lines).
Ops traps: a server started over ssh outlives stopping the runner (keeps the
port — `pkill -x <binary>` first); `systemctl start` of a root unit needs
sudo (polkit "Access denied" otherwise); old crash `ROCm error` lines live in
the journal forever — check `ActiveEnterTimestamp`/`NRestarts` before
treating a grep count as a live fault.

# Bandwidth Analysis: Multi-Node LLM Inference over Ethernet
## 0. Measured on the Qwen3.8-27B PP deployment (2026-08-17)
Everything in this section was measured on the live deployment
([[Qwen3.8 PP Deployment]]) while sampling `/proc/net/dev` at 50 Hz on
both ends. The theoretical tables below use H=4096/L=32; the real model
is larger (see constants), which raises the per-token bytes but not the
conclusions.
### 0.1 Verified constants (from the GGUF + env, not guessed)
| Constant | Value | Source |
| -------- | ----- | ------ |
| `hidden_size` (embedding_length) | 5120 | GGUF metadata (`qwen35.embedding_length`) |
| Blocks | 65 (45 on worker, 20 on head) | `--tensor-split 0.68,0.32` |
| FA layers | 16 total, interval 4 (11 worker / 5 head) | GGUF `full_attention_interval` |
| KV per FA layer per token | 3136 B (K q8_0 1088 + V f16 2048) | env file comment, confirmed |
| ubatch | 256 | `UBATCH_SIZE` in `frank-dragoon.env` |
| MTP verify step positions | 5 (1 + n_max 4) | `SPEC_DRAFT_N_MAX=4` |
| Link (old path) | 1 GbE via USB-C adapter on claw | `enx00e04cc2e1e5`, negotiated 1000 Mb/s |
| Link (current path) | 2.5 GbE eno1 to eno1 | negotiated 2500 Mb/s both ends |
| iperf3, 2.5 GbE path | 281 MB/s claw->server, 294 MB/s server->claw | measured |
| ping RTT, 1 GbE USB path | min 0.239 / avg 0.742 / max 1.085 / mdev 0.334 ms | measured |
| ping RTT, 2.5 GbE path | min 0.224 / avg 0.585 / max 0.883 / mdev 0.211 ms | measured |
The USB-C adapter added ~15 us to RTT (0.239 vs 0.224 ms min) and more
jitter (mdev 0.334 vs 0.211 ms).
### 0.2 Measured wire bytes (the number that matters)
Raw hidden state per position per direction = 5120 x 2 = **10.0 KB**.
The *measured* bytes per position per direction are ~4x that:
| Direction | Measured | Raw hidden |
| --------- | -------- | ---------- |
| head -> worker | 39.8 KB/position | 10.0 KB |
| worker -> head | 38.4 KB/position | 10.0 KB |
The extra ~30 KB/position is the serialized RPC graph (per-position
nodes for all 45 worker blocks: attention, KV append, SSM ops)
plus protocol framing. It scales with position count just like the
payload, so it does not shrink away.
Per ubatch (256 positions) the measured crossing is **20.5 MB**
(10.4 MB head->worker + 10.1 MB worker->head).
### 0.3 Measured throughput and the validated model
Measured prefill (fresh 13,959-token prompt, 14k context, 2.5 GbE
path): **457.9 t/s** (30,485 ms, journal task 11924). Decomposition:
| Term | 2.5 GbE (measured anchor) |
| ---- | ------------------------- |
| wire per ubatch (20.5 MB) | 70 ms |
| compute + overhead per ubatch (residual) | 489 ms |
| ubatch total | 559 ms = 2.18 ms/token |
Using that residual and only swapping the wire time per link speed:
| Link | wire/ubatch | predicted prefill | avg link use | line-rate burst duty |
| ---- | ----------- | ----------------- | ------------ | -------------------- |
| 1 GbE (old USB path) | 174 ms | **386 t/s** | 15.8% | 26.2% |
| 2.5 GbE (current) | 70 ms | 458 t/s (matches measured) | 6.4% | 12.5% |
| 10 GbE | 17 ms | **505 t/s** | 1.6% | 3.4% |
Delta: 1 -> 2.5 GbE is **+18.6% prefill**; 2.5 -> 10 GbE is **+9.4%**.
### 0.4 The KV snapshot: where the link really saturates
On task release, `llama-server` saves the conversation to the prompt
cache. The KV for the 11 FA layers living on the worker GPU must be
copied **worker -> head** for that snapshot, and the slot is BLOCKED
while it runs (`PARALLEL=1` = one user queues behind it).
Measured for a 98,100-token conversation: 3,454 MB copied (model check:
98100 x 11 x 3136 B = 3.38 GB, matches), at line rate (254 MB/s avg,
308 MB/s peak).
| Link | snapshot duration (slot blocked) |
| ---- | -------------------------------- |
| 1 GbE | ~31 s |
| 2.5 GbE | 13.6 s (measured; journal: "prompt cache update took 14418 ms") |
| 10 GbE | ~5 s |
This is the only phase that runs the link at ~100% utilization for a
long time. Prefill runs at 12-26% of line rate in bursts (per ubatch)
and ~6-16% on average; decode runs at ~2% or less.
### 0.5 Decode (MTP verify step, 5 positions)
| Link | net time per step | share of 164 ms step | decode t/s |
| ---- | ----------------- | -------------------- | ---------- |
| 1 GbE | 4.0 ms (RTT 0.74 + wire 3.4) | 2.4% | ~23.0 |
| 2.5 GbE | 1.9 ms (RTT 0.59 + wire 1.4) | 1.1% | 23.47 (measured) |
| 10 GbE | 0.6 ms (RTT ~0.25 + wire 0.3) | 0.4% | ~23.5 |
Decode is latency-touched but bandwidth-trivial. Average wire rate
~19 Mbit/s in each direction.
### 0.6 Verdict for the 10 GbE USB-C adapter question
- The 1 GbE -> 2.5 GbE upgrade (the big win) is already captured for
free: the claw's native 2.5 GbE `eno1` now carries the RPC path
(the 1 GbE USB adapter was unplugged 2026-08-17; routing moved the
path, the RPC TCP re-attached on the new interface).
- 2.5 -> 10 GbE buys +9.4% prefill and 13.6 s -> 5 s snapshot blocking.
It requires the L2 device at 192.168.0.1 to be 10G-capable, or a
direct cable between the two machines (dedicated link, second IP
pair, or a lower-metric static route).
- At current usage (PARALLEL=1, decode-heavy), 2.5 GbE is comfortable.
## 1. Bandwidth Math: Bytes per Token per Layer Boundary
### 1.1 Pipeline Parallelism (PP)
During autoregressive generation, each transformer layer produces a hidden state of shape `(batch_size, hidden_size)`. At a pipeline stage boundary, this tensor must be communicated between nodes.
**Forward pass only (inference):**
```
bytes_per_boundary = batch_size × hidden_size × 2 [fp16 = 2 bytes]
```
**Key detail:** During *generation* (one token at a time), seq_len = 1 at each boundary crossing. The KV cache stays local. The hidden state is `(batch, hidden_size)` — independent of context length.
**For a 27B dense model (e.g., Qwen3.6-27B):**
- Hidden size: H = 4096 (standard for Llama/Qwen-style architectures).
Note: the Qwen3.8-27B actually deployed on this fleet has H = 5120
(GGUF-verified); see section 0, which supersedes these theoretical
numbers with measurements.
- Per-token, per-boundary: `4096 × 2 = 8,192 bytes = 8 KB`
- With Nₚₚ stage boundaries: total = `Nₚₚ × 8 KB/tok`
**For a 36B MoE model (e.g., Qwen3.6-35B-A3B):**
- Hidden size: H = 6144 (common for this scale)
- Layers: L = 48 (typical)
- Per-token, per-boundary: `6144 × 2 = 12,288 bytes = 12 KB`
- With Nₚₚ stage boundaries: total = `Nₚₚ × 12 KB/tok`
**Full example — 27B model, 2 PP stages (1 boundary), batch=1:**
```
1 boundary × 4096 × 2 bytes = 8,192 bytes/tok
```
**Example — same model, batch=64:**
```
1 boundary × 4096 × 64 × 2 bytes = 524,288 bytes = 512 KB/tok
```
**Example — 36B model, 2 PP stages, batch=1:**
```
1 boundary × 6144 × 2 bytes = 12,288 bytes = 12 KB/tok
```
### 1.2 Tensor Parallelism (TP) — for comparison
In tensor parallelism, each MLP and attention layer performs an all-reduce on the hidden state:
```
bytes_per_layer = batch_size × hidden_size × 2 [one all-reduce per layer]
total_bytes_per_tok = L × batch_size × hidden_size × 2 [L all-reduces total]
```
**For 27B, H=4096, L=32, TP=2, batch=1:**
```
32 layers × 4096 × 1 × 2 bytes = 262,144 bytes = 256 KB/tok
(16 KB per layer all-reduce × 32 layers)
```
**For 36B, H=6144, L=48, TP=2, batch=1:**
```
48 layers × 6144 × 1 × 2 bytes = 589,824 bytes = 576 KB/tok
(12 KB per layer all-reduce × 48 layers)
```
### 1.3 Scaling with batch size

**27B TP batch=64 at 100 tok/s: 1310.72 Mbit/s ≈ 2.5 GbE usable (2500 Mbit/s) — ~52% saturated**
**Key finding:** PP is feasible across all ethernet classes for all batch sizes up to at least 100 tok/s. TP becomes bottlenecked on 1 GbE at batch=64 and 100 tok/s.
---
## 3. Why PP is the Only Realistic Option over Ethernet
### 3.1 Communication cost comparison
| Scheme | Communication per tok per rank | 27B, H=4096, batch=1 | 36B, H=6144, batch=1 |
|--------|------|---|---|
| PP (Nₚₚ boundaries) | Nₚₚ × H × 2 | Nₚₚ × 8 KB | Nₚₚ × 12 KB |
| TP (L layers all-reduce) | L × H × 2 | 32 × 8 KB = 256 KB | 48 × 12 KB = 576 KB |
PP communication per token is **L/Nₚₚ times smaller** than TP communication per token (factor of ~16× for 2 PP stages).
### 3.2 Latency-bound nature of autoregressive generation
During autoregressive generation, each layer computes one token at a time. In TP, every layer requires an all-reduce (2× ring latency or 1× tree latency per layer). For L=32 layers, that's 32 synchronization points per token.
In PP, activations cross the stage boundary only once per layer (or L/Nₚₚ times). The critical path is:
```
Stage 0 computes → send hidden state across boundary → Stage 1 computes → ...
```
This is a single bottleneck per token, with latency proportional to network RTT × number of stages, not L.
### 3.3 Bandwidth utilization
With PP, each boundary crossing transfers `H × 2` bytes. For 8 KB at 1 GbE, the transfer completes in ~68 µs. This is negligible compared to compute time (milliseconds per layer on a GPU). The link is underutilized.
With TP, each layer transfers `H × 2` bytes but this happens L times. For 256 KB total at 1 GbE, that's ~2 ms of pure transfer time — potentially comparable to compute time on a fast GPU.
### 3.4 Real-world evidence
- Petals uses PP exclusively over the public internet and achieves usable inference at 1–2 tok/s even with 100 Mbit/s links [1].
- llama.cpp RPC splits layers across nodes in pipeline order, not tensor sharding [2].
- exo uses TP but achieves speedup only with RDMA over Thunderbolt (~50 Gbit/s) [3].
- Petals paper Table 3: inference performance does **not depend much on bandwidth** (1 Gbit/s vs 100 Mbit/s gives nearly identical results) but **degrades significantly with higher latency** [1].
**Conclusion:** For gigabit-class ethernet, PP is the only practical multi-node parallelism strategy for inference. TP can work on 10 GbE for small batches but saturates at 1 GbE with moderate batch sizes.

### 4.2 Detailed notes
**Petals [1]:**
- Uses pipeline parallelism with dynamic 8-bit quantization (halves bandwidth)
- For BLOOM-176B (H=14336), per-boundary communication is ~14 KB/tok with quantization
- Recommended bandwidth: 25 Mbit/s bidirectional for interactive inference [1]
- Key finding: "For inference, performance does not depend much on bandwidth or sequence length but degrades with higher latency" — RTT matters more than throughput
- At 1 Gbit/s with <5 ms RTT: 1.71 steps/s; at 100 Mbit/s with <5 ms: 1.66 steps/s (only 3% difference)
- At 100 Mbit/s with 100 ms RTT: 1.23 steps/s (28% degradation)
**llama.cpp RPC [2]:**
- Model weights and KV cache distributed across nodes proportionally to memory
- Default: pipeline-style distribution of layers (first layers on node A, last on node B)
- Each node runs `ggml-rpc-server`, main host uses `--rpc` flag
- RDMA transport supported (RoCEv2), negotiated automatically with libibverbs
- Over ethernet, performance decreases with more nodes (each extra node adds a hop)
- Over RDMA/TB5, performance scales up with more nodes (less latency per hop)
**Exo [3]:**
- Uses tensor parallelism with MLX distributed backend
- With RDMA over Thunderbolt 5: up to 1.8× speedup on 2 devices, 3.2× on 4 devices
- Topology-aware auto-parallelism considers latency/bandwidth between links
- Thunderbolt 5 provides ~50–60 GbE real-world throughput (RDMA)
**Key insight from all systems:** Ethernet (1 Gbit/s) is sufficient for PP inference of 20–40B models because per-token activation traffic is small (8–12 KB/boundary). The bottleneck is **latency** (RTT between nodes), not bandwidth.

## 5. Overheads
### 5.1 TCP/IP overhead
| Overhead | Amount |
|----------|--------|
| Ethernet header + trailer | 18 bytes (14 + 4 FCS) |
| IPv4 header (no options) | 20 bytes |
| TCP header (no options) | 20 bytes |
| Total per packet | ~58 bytes overhead |
| MTU (jumbo frames 9000) | 9000 bytes payload → 0.6% overhead |
| MTU (1500 standard) | 1500 bytes payload → 3.9% overhead |
**Practical impact:** For 8 KB transfers (27B PP boundary), use jumbo frames where possible to minimize TCP overhead. For small transfers (< 1.5 KB), a single TCP packet is used and the overhead is 58/8192 = 0.7% per transfer — negligible.
### 5.2 RPC/serialization overhead
- llama.cpp RPC: Protobuf serialization adds ~10–20% overhead for small tensors
- Petals: PyTorch tensor serialization over hivemind/gRPC, adds serialization time
- vLLM PP: gRPC with protobuf, similar overhead
- Serialization scales with tensor size: negligible for 8 KB+ tensors
### 5.3 Pipeline bubble overhead
With Nₚₚ pipeline stages and microbatching, the pipeline bubble fraction is:
```
bubble_fraction = (Nₚₚ - 1) / (Nₚₚ + microbatches - 1)
```
For 2 stages, 1 microbatch (single tok): bubble = 1/2 = 50% idle time.
For 2 stages, 8 microbatches: bubble = 1/9 = 11%.
In autoregressive generation with batch=1 and no microbatching, each stage processes one token sequentially:
- Stage 0 finishes, sends hidden state, waits for Stage 1
- Stage 1 processes, returns result, Stage 0 processes next token
- Effective utilization ≈ 1/Nₚₚ if no pipelining overlap
**Mitigation:** Process multiple tokens before waiting. Send next token to Stage 0 while Stage 1 is computing — pipelining reduces bubble.
### 5.4 Per-hop LAN latency
| Network | Typical RTT | One-way latency |
|---------|------------|-----------------|
| 1 GbE (Cat6) | 30–50 µs | 15–25 µs |
| 2.5 GbE (Cat6) | 30–50 µs | 15–25 µs |
| 10 GbE (Cat6a) | 20–30 µs | 10–15 µs |
| RoCEv2 (IB/25GbE) | 1–5 µs | <5 µs |
| RDMA (Thunderbolt 5) | 10–30 µs round-trip end-to-end | — |
**Impact on PP inference:** With Nₚₚ = 2 stages and batch=1, one token takes:
```
t_compute + t_roundtrip + t_compute
```
At 30 µs RTT and ~2 ms layer compute time per GPU: the network adds ~30 µs, which is 1.5% of total. Negligible at LAN speeds.
With Nₚₚ = 4 and 30 µs per-hop RTT: ~120 µs network, still <6% of compute time.
### 5.5 Quantization overhead
- Petals uses dynamic blockwise 8-bit quantization: halves hidden state bandwidth from 16-bit to 8-bit [1]
- For 27B: 8 KB → 4 KB per boundary with 8-bit quantization
- Accuracy impact: <1% on standard benchmarks [1]
- Quantization/dequantization adds ~1–5 ms per stage on modern GPUs (negligible vs. compute)
---
## 6. Conclusions and Recommendations
### For the 27B / 36B models on gigabit-class ethernet:
1. **1 GbE is sufficient for PP inference** up to at least 100 tok/s at batch=64 (81.92 Mbit/s required, well under 1000 Mbit/s capacity). Even with TCP/IP and RPC overheads, margin is >90%.
2. **Pipeline parallelism is the correct choice** over ethernet — PP sends 8–12 KB per boundary vs. 256–576 KB for TP, a 32× advantage for 2 PP stages.
3. **Latency matters more than bandwidth** — the Petals paper demonstrates that dropping from 1 Gbit/s to 100 Mbit/s only reduces throughput by ~3%, while increasing RTT from 5 ms to 100 ms reduces it by ~28%.
4. **With 8-bit quantization**, bandwidth requirements halve, providing additional safety margin.
5. **Jumbo frames recommended** to minimize TCP overhead on larger transfers.
6. **For batch sizes ≥ 16**, 1 GbE remains viable for PP but consider 2.5 GbE for headroom and faster model loading.

# Expected Performance
This page estimates the speed of a 25-40B model split across two machines
over ethernet. It uses the bandwidth math in [[Ethernet Bandwidth Math]]
and the measured numbers in [[Mixed-Vendor Experiments]].
## The Bandwidth Ceiling Is Not the Limit
A pipeline boundary moves only the hidden state. For a 27B model (hidden
5120), that is 10240 bytes per token per boundary in fp16. Even at 64
tokens per second with batch 64, the traffic is about 262 Mbit/s. 1 GbE can
carry it. The real limits are latency, RPC overhead, and the slowest node.
The Petals paper measured this directly. Dropping from 1 Gbit/s to
100 Mbit/s changed throughput by 3 percent. Raising round-trip latency from
5 ms to 100 ms dropped throughput by 28 percent. Latency matters more than
bandwidth for pipeline inference.
## Real Benchmark Anchors
| Experiment | Model | Network | Decode (t/s) |
| ---------- | ----- | ------- | ------------ |
| Mac Studio + DGX Spark (Metal+CUDA) | Qwen2.5-72B Q4 | 10 GbE | 6 |
| Mac Studio + DGX Spark (Metal+CUDA) | Qwen2.5-7B Q4 | 10 GbE | 53 |
| RTX 4070 + MI50 + 3050 (CUDA+ROCm) | Qwen3-VL-30B Q5 | 1 GbE | 51.5 clean, 17.8 at 32k ctx |
| Two Strix Halos (ROCm RPC) | MiniMax-M2.5-139B Q8 | USB4 | 15.35 |
| AMD four-node Strix Halo (5 GbE) | Kimi K2.5 (1T) | 5 GbE | 8.30 |
| Tesla V100 + R9700x2 (Vulkan, one box) | Qwen3.6-35B-A3B Q8 | PCIe | 62 |
Pattern: RPC decode runs about 2-5 times slower than the best single node.
Prefill benefits from more compute across nodes. The 30B-class model over
1 GbE with warm cache reached 51.5 t/s on a short context and 17.8 t/s at
32k context.
## Estimate for Qwen3.6-27B Q8, Two Nodes
Scenario: RTX 3090 (24 GB VRAM, NVIDIA desktop) plus Strix Halo NUC
(Radeon 8060S, 30 GB physical RAM). The model is the dense 27B at Q8
(29-32 GB). Each node holds part of the weights and KV cache.
| Link | Decode (t/s) | Prefill (t/s) | Notes |
| ---- | ------------ | ------------- | ----- |
| 1 GbE | 8-15 | 200-500 | Latency-bound; per-token RPC round trip |
| 2.5 GbE | 10-18 | 250-600 | Some headroom; latency still dominant |
| 10 GbE | 12-20 | 300-800 | Closest to the published 10 GbE runs |
The dense 27B decodes slower per token than the MoE 30B A3B class. Expect
the lower half of the ranges at full context.
### With Speculative Decoding
Speculative decoding (MTP, DFlash, or ngram-mod) raises effective decode.
Tightwad measured 1.86x on a slow RPC pool. Estimate the effective rate at
1.4-1.8x the raw RPC decode:
| Link | Raw decode (t/s) | With spec (t/s) |
| ---- | ---------------- | --------------- |
| 1 GbE | 8-15 | 12-24 |
| 2.5 GbE | 10-18 | 15-28 |
| 10 GbE | 12-20 | 18-32 |
## Context That Fits
The two real machines give about 51 GiB of usable memory combined
(24 GiB VRAM plus about 27 GiB on the Strix Halo, which has 30 GiB physical
RAM; the 96 GiB driver ceiling is not physical). A 29-32 GB model leaves
about 20-22 GiB for KV cache. The Qwen3.6-27B KV cache costs about 85-100
KiB per token with q8_0 K and f16 V (measured on the large service at
602100 tokens = about 50 GB). That budget gives a total context pool of
roughly 200k-260k tokens across both nodes.
## Caveats
- Every node must run the exact same llama.cpp build. Version skew hangs
the handshake.
- The slowest node sets the pace for every token.
- Model load crosses the network once per start. Expect minutes, not
seconds, for the split load.
- These are estimates. The exact combination of an RTX 3090 desktop and a
Strix Halo NUC has no published benchmark yet.
