## 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
<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 TP=2 here. A one-card collective proves
nothing: NCCL short-circuits at `world_size=1`. [[PCIe Link and Atomics]]
- **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!`), never from vLLM or RCCL — the env var costs one line and prints the
failing HIP call with its return code. [[PCIe Link and Atomics]]
**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>`),
and the flattened copy fails at *request* time, not load time: the engine
reads the weights, answers `/health` and dies on the first completion with
`Cannot read .../TensileLibrary.dat: No such file or directory for GPU arch
: gfx1201`. Declare the destination, then copy the contents.
- **mmap must stay on** for the big-PLE models: `--no-mmap` forces the
~50 GiB PLE table into anonymous memory → silent cgroup kill, dmesg is the
only evidence. mmap pages ARE page cache. Never pin the PLE tensor with
`-ot` (23 → 13.4 t/s).
- **HIP reads bare env vars** `TEMP`, `HOST`, `GPU_MAX_HEAP_SIZE`. Serve
scripts export env files with `set -a`, so a tunable named `TEMP` leaks
into HIP (`TEMP=1.0` sent the JIT cache to path `1.0` and segfaulted every
load, fixed 2026-08-13 by renaming to `TEMPERATURE`). Never name a tunable

per-layer `blk.<il>.hc_attn_norm.weight` and ship only `blk.48` (verified

`gtt_total=122402963456` in `/sys/class/drm/card1/device/`). The older
"64 GiB, SVM-backed" lesson was already stale — the CIRU Orca predecessor
held 92.6 GiB of weights on the iGPU. `free`/`dmidecode` show the
CPU-side carve-out — intentional, do not change.
- **`GGML_CUDA_FA_ALL_QUANTS` is dead; do not build for it.** Verified on this host 2026-10-19:
master's `ggml/cmake/common.cmake` warns it is deprecated in favour of `GGML_CUDA_FA_QUANTS`, the
successor's DEFAULT pair list (`q4_0-q4_0;q8_0-q8_0;f16-f16;bf16-bf16`) already compiles the
quantized-KV kernels with the old flag OFF, and neither llama tree on this host references the old
macro anywhere under `ggml/src/ggml-cuda/`. The old "~12× prefill collapse" belongs to the older
source line. Prove a build's KV ability from its `CMakeCache.txt`. [[frank-zealot]]

**Load / crash diagnosis**
- Model load is slow (minutes cold); health returns 503 while loading; do
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
`LimitMEMLOCK=infinity` — systemd is privileged and 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. [[frank-dragoon]]
- **A GGUF's custom tensor type picks the runtime — read the histogram before promising a
file to a loader.** A non-standard tensor type in the KV section makes stock loaders refuse
the file at load, so a fork can be the only door rather than a preference. Counting tensor
types takes one python read and settles a runtime argument in minutes; build identity matters
as much as the fork, so pin the commit by SHA in any build script. [[GGUF Compatibility]]
- **Speculative-decode flags move as a SET.** Handing the fork `--model-draft` with no `--spec-type`
(the naive way to build a "no MTP" bench arm) segfaulted at load, core dumped, no diagnostic. 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. [[frank-zealot]]
- **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 and pushed `available` to 3 GiB, so
every later rate was suspect. Record the child pid, kill it in a `finally`, then prove `free` came
back before believing a number — and kill by pid, never `pkill -f llama-server`.
**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 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

same arm served production for 24 minutes with real numbers (~48 t/s decode, 801 t/s prefill at

drop-in as an unfinished experiment and reported a hijack. Write the measurement into the

are not records.
- **`llama-bench` separates a LIST with `/` and SWEEP values with `,`** — for both `-dev` and

- **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

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

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

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

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.

- 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

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

- **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.

There is no page for a retired endpoint and no change diary. A payload swap
appends one row to the live endpoint's **Eras** table; when the endpoint itself
dies, its page is destroyed. Rollback is a commit, not a document.

is a liability — the next agent spends context on a number that AI progress has already
obsolete. This pass moves those pages to `.AGENTTRASH/` (repo law: never `rm`) and then

"""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.

# 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]].

| 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
`UserWriteStageView.update_user` on a throwaway user (new password valid, old
invalid).
## Outpost claim cache (`proxysession`) — 403 after a group add
The embedded outpost does not re-evaluate group membership per request. Each
completed authorize writes one row to `authentik_providers_proxy_proxysession`
whose `session_data` JSON holds the claims (`groups` included) that get served
for that browser session until the row expires (observed TTLs 1–24 h per

# Dual R9700 Cooperation
Dankserver's two R9700s run **one tensor-parallel engine across both cards** —
today that is `frank-archon` under radiance 1.0.13, TP=2
([[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)
All Qwen cards use Q4_1 unless noted. Context lengths are the FLM-published maxima.
| Tag | Base model | Context max | Notes |
|-----|-----------|-------------|-------|
| `qwen3:0.6b` | Qwen3-0.6B | 32k | thinking toggle |
| `qwen3:1.7b` | Qwen3-1.7B | 32k | thinking toggle |

## 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.
Qwen3.5, FLM v0.9.38, Kraken Point 32 GB DRAM. Decode t/s by starting context length:
| Model | 1k | 2k | 4k | 8k | 16k | 32k |

| Prefill t/s | 78.98 | 118.04 | 156.43 | 197.93 | 218.84 | 221.96 |
- 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

# 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.

# 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.

# Qwen3.8-27B Pipeline-Parallel Deployment (Dankclaw + Dankserver)
Split Qwen3.8-27B across the Strix Halo iGPU (head) and the RTX
3090 (worker) using llama.cpp RPC. This page is the design record and the
morning-of runbook. Research background:
[Qwen3.8 Strix optimizations](../qwen3.8-strix-optimizations.md).
## Production state (2026-08-17: Q6_K, q8_0/f16 KV, split 0.68)
This split is the production `frank-dragoon` service. Current
state, verified against the live journal and output smoke tests
(2026-08-17, load 02:06):
- Model: `Qwen3.8-27B-Uncensored-Q6_K.gguf` (22.43 GB, imatrix, no
bundled MTP head). Draft: `Qwen3.8-27B-Uncensored-draft-Q8_0.gguf`
(3.16 GB) via `--spec-draft-model`, running on ROCm0 only (1718 MiB;
zero worker impact — measured, not assumed).
- Split `0.68,0.32` = 45 of 65 blocks (0-44) on the 3090 — 69% of the
layer weight. Maximum for this config; see "Split limits" below.
- KV: K `q8_0` + V `f16` (mismatched), 784 MiB per FA layer: RPC0 8624
MiB (11 FA) + ROCm0 3920 MiB (5 FA). Flash Attention ENABLED despite
the mismatch (`resolve_fused_ops: Flash Attention enabled`) via the
GGML_CUDA_FA_ALL_QUANTS rebuild — see "FA-all-quants rebuild" below.
- Pool `262144`, `PARALLEL=1`, live `n_ctx_slot = 262144`.
* MTP: standalone draft head, acceptance 0.83 then 0.75, mean len 4.0-4.3,
per-position ~0.86/0.71/0.71/0.71 — stronger at every position than the old bundled
head, which measured 0.739/0.554/0.427/0.340.
- Spec chain as deployed: `--spec-draft-n-max 4` on the standalone draft, with
the `--spec-default` ngram-mod fallback at n_match 24 / n_min 48 / n_max 64
(the preset that survived the DSpark/DFlash retirements —
[[qwen3.8-spec-matrix]]).
- Batch 8192 / ubatch 256, `--direct-io`, `--fit off`, `--gpu-layers all`. The
pi `models.json` declared 262144 (`contextWindow = maxTokens`, the house
convention of that era).
- Head GPU side: **ROCm0** (no `--device` flag; HIP registers before
Vulkan).
- Worker steady state: 23854/24576 MiB used, ~273 MiB free (tight but
stable; all allocations are upfront).
- Unit `frank-dragoon.service`, launched through
`serve-pp-head.sh` + `frank-dragoon.env`.
## Service enablement (2026-08-17)
The PP pair is the only inference service enabled for boot. Both units
(`frank-dragoon` on Dankclaw, `frank-pp-worker` on Dankserver) are
enabled. The NPU unit (`frank-zealot` on Dankclaw) and all retired
units are disabled. Restart order: worker first, then head. The Dankserver
helper `frank-restart-small.sh` is obsolete (it restarts the removed
`frank-zealot` unit); restart the worker with
`sudo systemctl restart frank-pp-worker`. The Dankclaw helper
`frank-restart-large.sh` (sync + cache drop + restart) is correct for the
head. The "deploy.sh dankserver is broken until retargeted" note is long fixed:
`./scripts/deploy.sh dankserver --service frank-archon` is the documented
invocation today (`scripts/deploy.sh:38`, dispatch case
`dankserver:frank-archon` at `scripts/deploy.sh:149`). See
[[deployment]] for the full boot-policy table.
## FA-all-quants rebuild (2026-08-17)
Flash Attention with mismatched K/V cache types requires the
`GGML_CUDA_FA_ALL_QUANTS` compile definition. Without it,
`ggml/src/ggml-cuda/fattn.cu` gates FA off when `K->type != V->type`
(`#ifndef GGML_CUDA_FA_ALL_QUANTS`). With it, the K==V check is skipped
and all quantized-K combos are compiled. The head (HIP gfx1151) and the
worker (CUDA sm_86) compile the same sources, so the same CMake flag
covers both:
cmake -S . -B build -DGGML_CUDA_FA_ALL_QUANTS=ON
cmake --build build -j --target llama-server # dankclaw
cmake --build build -j --target ggml-rpc-server # dankserver
Both hosts at commit 9b05354ec (b10433). The flag was already cached
ON in the worker build (Aug 16 objects carry it); the head required a
full ggml-hip rebuild. Keep both binaries on the same commit — version
skew hangs the RPC handshake.
## Split limits (measured 2026-08-17, Q6_K + q8_0/f16 KV)
KV per FA layer at 262144 = 784 MiB (K q8_0 1088 B/token + V f16 2048
B/token). Layer pool 20334 MB (GGUF scan, exact), embd on the head side
(RPC0 buffer 10429.88 MiB at f=0.53 -> the split pool excludes embd).
- f=0.53 -> 35 blocks, 8 FA, KV 6272 MiB, 5721 MiB free. Phase 1.
- f=0.68 -> 45 blocks (0-44), 11 FA (3..43), KV 8624 MiB, 273 MiB
free. PRODUCTION (the max): 46 blocks leaves ~0.3 GiB; 48 blocks
(f >= 0.7197, the round(f x 66) boundary) adds FA block 47 -> KV
9408 -> OOM by ~0.85 GiB.
The KV-per-device count = round(f x 66) layers, independent of the
weight boundary (same rule as the Q8_K_XL config). FA blocks at
3,7,...,63.
## Split limits (measured 2026-08-17, Q8_K_XL + f16/f16 KV) — superseded
The 0.40 split (2026-08-16, 2x200700 pool) was KV-bound at 26 blocks.
With the pool shrunk to 262144, the KV per full-attention layer drops to
exactly 1024 MiB, freeing headroom. Measurements:
- 0.50,0.50 -> 32 blocks (0-31), 8 FA on RPC0, KV 8192 MiB, 1477 MiB
free. Healthy (2026-08-17 00:29 load).
- 0.55,0.45 -> 36 blocks (0-35): the 9th FA block, KV 9216 MiB ->
cudaMalloc OOM by ~740 MiB.
- 0.54,0.46 -> weights 35 blocks (0-34) but KV still 9216 MiB -> OOM.
The KV-per-device count rounds the split fraction over 66 layers
(round(f x 66)), independent of the weight boundary; the 9-FA flip
sits at f ~= 0.538, just below the weight threshold for block 35, so
the 35-block config is unreachable.
- 0.53,0.47 -> 34 blocks (0-33), 8 FA, KV 8192 MiB. Safe under every
rounding rule (round/floor/ceil of 0.53 x 66 = 34.98). Production.
GGUF block scan (exact sizes): FA blocks at 3,7,...,63 (409.6 MB each),
linear blocks 431.3 MB; total layer weight 27720 MB. The split pool
includes the MTP head for weights and token_embd for KV — the two
boundaries diverge, which is why 0.54 split them apart.
## Cache incident (2026-08-17): garbage output from a full worker disk
Symptom: after a split change, the service loaded "healthy" but every
completion degenerated to a repeated junk token (e.g. 48 x "/", empty
content, degenerate logits). Root cause chain:
1. The worker RPC tensor cache keys per session. Each model load writes
a fresh full copy (~15 GB); over ~5 sessions of two models it grew to
4434 files / 96 GB.
2. The Dankserver root disk filled to 100%. Cache writes started
failing, leaving 0-byte entries. A subsequent reload hit corrupt
cache entries and the worker served garbage weights for the
newly-needed layers without validation.
3. Fix: move the cache to .AGENTTRASH (then empty it), restart the
worker, free the disk, reload the head (full re-stream ~2.5 min).
A clean cache and a healthy disk produced correct output immediately
(acceptance 0.89 on the first smoke test).
Guard was `scripts/prune-rpc-cache.sh` on Dankserver (cron, 40 GiB cap). That
script is gone from the repo and from the host, yet the crontab line still
runs every 10 minutes against it
(`*/10 * * * * /home/dank/vLLM/scripts/prune-rpc-cache.sh`, `crontab -l`, read
2026-10-18 — the target does not exist, so it fails silently). Never let the
cache directory grow unchecked; a full disk silently corrupts it. Signature to
recognize: healthy load + degenerate repeated-token output.

- **Layer-sequential split** (true pipeline parallelism): layers 0..N run on
the worker, the rest on the head, in order. One hidden-state handoff per
token step. DECODE is RTT-bound, not bandwidth-bound (network is ~1-2.5%
of step time). PREFILL and the prompt-cache KV snapshot ARE
bandwidth-bound: the link runs at line rate for the wire burst of every
ubatch and ~100% during the snapshot copy. Measured numbers:
[[Ethernet Bandwidth Math]] section 0.
- **Why the head is on Dankclaw:** the model file is already there; the
worker streams its tensor share at load (no 31.5 GB copy to the server).
- **Both sides must run the identical build** (b10433 / 9b05354ec). The
worker build lived in a worktree `/home/dank/llama-cpp-rpc` on Dankserver so the
production b10121 build stayed untouched (that path no longer exists, read
2026-10-18). A version skew hangs the RPC handshake with no error.
## Files
| File | Machine | Purpose |
|------|---------|---------|
| `scripts/frank-pp-worker.env` | server | worker tunables (bind, port, device, cache) |
| `scripts/serve-pp-worker.sh` | server | runs `ggml-rpc-server` from the b10433 worktree build |

| `scripts/serve-pp-head.sh` | claw | runs `llama-server --rpc ...` (see "Gotchas") |
| `scripts/frank-dragoon.service` / `frank-pp-worker.service` | both | optional systemd units (manual install); the head unit was renamed from `frank-pp-head.service` on 2026-08-16 and is symlinked from the repo into `/etc/systemd/system` |
| `scripts/pp-test.sh` | any box with ssh to both | test orchestrator (preflight/start/verify/bench/stop-pp/restore) |
| `scripts/pp-bench.py` | claw | API driver; reports server-side `print_timing` |
**Every PP file in that table except `scripts/frank-dragoon.env` no longer
exists** (checkout read 2026-10-18: `frank-pp-worker.env`,
`serve-pp-worker.sh`, `serve-pp-head.sh`, `frank-pp-worker.service`,
`pp-test.sh`, `pp-bench.py` and `prune-rpc-cache.sh` are all absent), and
`scripts/frank-dragoon.env` is today the halogen-flash-server env, not a PP
head env ([[frank-dragoon]]).
## Gotchas (all verified in b10433 source / live tests, 2026-08-15)
1. **No `--device` on the head.** Setting `params.devices` makes
`llama_prepare_model_devices` use exactly that list; the RPC device is
silently dropped and `--rpc` becomes a no-op. Omit it; default selection
puts RPC first.
2. **The iGPU side is ROCm by default.** Backends register in fixed order
(HIP before Vulkan); the iGPU dedup rule keeps the first backend's view.
Live check showed `[RPC0, ROCm0]`. For a Vulkan side, use the second
head build `/home/dank/llama.cpp/build-vulkan-rpc` (HIP off; removed — the
path is gone on 2026-10-18) — set `HEAD_BIN` in the env. Trade: ROCm side =
faster prefill, ~3% slower decode (measured on this box).
3. **Pin `--tensor-split 1,1`.** The default split is proportional to
*reported free memory*: the Strix reports up to 96 GiB (GTT) vs the
3090's 24 GB, so the default lands ~20/80 on the slow device. 1,1 = 50/50 =
balanced per-layer latency. The 2026-08-15 4B smoke test that proved it
(production untouched): at a 0.2/0.8 split only 4 of 36 layers reached the
3090, and at a real split worker VRAM rose ~819 MiB with 95 t/s prefill /
58.8 t/s decode on the tiny model; link RTT ~0.3–0.5 ms.
4. **`-dio` on the head.** Large model + RPC hangs at load without direct
I/O.
5. **RPC is unauthenticated and unencrypted.** LAN only. The worker binds
0.0.0.0-equivalent by design (`--host 192.168.0.235`).
6. **Env var names.** Never `TEMP`, `HOST`, or `GPU_MAX_HEAP_SIZE`
(HIP runtime reads them; the 2026-08-13 `TEMP` incident).
7. **Page-cache state confounds loads.** `pp-test.sh start` drops caches on
the head before load (warm-cache loads crash fast; cold loads survive).
## Runbook (morning of 2026-08-16)
Run from any box with ssh access to both (repo path on claw:
`/home/dank/vllmScripts`, on server: `/home/dank/vLLM` — both still exist as
stale checkouts; the deployment checkout today is `/home/dank/serverAppConfigs`
on both hosts).
```
# 0. one-time: pull the kit on both boxes
ssh dank@dankclaw 'cd /home/dank/vllmScripts && git pull'
ssh dank@dankserver 'cd /home/dank/vLLM && git pull'
# 1. checks (read-only)
./scripts/pp-test.sh preflight
# 2. full run: stop prod -> start PP -> verify split -> bench -> restore
FRANK_SUDO_PW=<pw> ./scripts/pp-test.sh all
# or step by step:
FRANK_SUDO_PW=<pw> ./scripts/pp-test.sh start
./scripts/pp-test.sh verify # layer split + worker VRAM
./scripts/pp-test.sh bench 4 256 2 # ~4k prompt, 256 out, 2 reps
./scripts/pp-test.sh bench 16 256 1
FRANK_SUDO_PW=<pw> ./scripts/pp-test.sh stop-pp
FRANK_SUDO_PW=<pw> ./scripts/pp-test.sh restore
```
Config variants: edit `scripts/frank-dragoon.env` on the claw (git commit +
pull if the bench runs from the repo), then re-run `start` + `bench`:
- No spec baseline: `SPEC_NONE=1`
- Vulkan head side: `HEAD_BIN=/home/dank/llama.cpp/build-vulkan-rpc/bin/llama-server`
- Q4_0 MTP draft head: add `--spec-draft-model /home/dank/models/Qwen3.8-27B-MTP-Q4_0.gguf` to the serve script's SPEC block (env hook: see `SPEC_DRAFT_MODEL` below)
- n_max sweep: `SPEC_DRAFT_N_MAX=3|4|5`
- Plain Q8_0: `MODEL_FILE=Qwen3.8-27B-Q8_0.gguf` (file must be on the claw)
Verification checklist after each `start`:
1. `verify` shows `using device RPC0 ... using device ROCm0|Vulkan0`.
2. Layer assignment lines (`-lv 10`): worker gets the first ~32 layers at a
1,1 split.
3. `nvidia-smi` on the server showed ~15–16 GB used by the worker
(production small service + worker share). No NVIDIA card is in that host
today — the equivalent check is `rocm-smi --showmeminfo vram`.
4. Head GTT usage (rocm-smi) well under 96 GiB; model fully on devices
(`--gpu-layers all` offloads everything; CPU holds embeddings/lm_head glue).
## Expected numbers
Per-layer: 3090 ≈ 2–3× faster than the 8060S. 50/50 split → each token
step ≈ max(32 layers on 3090, 32 layers on Strix) + ~0.5 ms RTT.
- Production reference: 25 t/s @16k (Vulkan, spec, single node).
- Target: **≥ 30 t/s @4k, ≥ 20 t/s @16k** with spec.
- Decode floor: with ngram/mod acceptance, spec multiplies the raw rate;
raw (no spec) rate should clear ~15–18 t/s @16k for the target to hold.
## Rollback
`pp-test.sh restore` starts both production services. If a PP test wedges a
box: `systemctl restart <unit>` after killing the stray processes
(`pkill -x llama-server` / `pkill -x ggml-rpc-server` — never `pkill -f`
with a pattern matching your own ssh command line).
## Open questions for the test day
1. Does the MTP head (which sits in the last layer group, iGPU side) draft
cleanly with the verify pass crossing the RPC boundary? Watch acceptance
in the head log (`draft acceptance = X`).
2. Two parallel slots on the split (PARALLEL=2, CTX 65536): RPC is
serialized per compute — expect the 2-slot speedup to be weaker than
single-node. Measure, do not assume.
3. Prefill parity: ROCm-side head should prefill ≥ single-node ROCm; if not,
the ubatch crossing the RPC boundary is the suspect.

# Sample Script Set — Two-Node Qwen3.6-27B Q8 Split
> WARNING. This page is for educational reading only. Do not run these
> scripts. Do not deploy them. They are a template, not a tested product.
> The RPC backend is a proof of concept that the upstream README calls
> "fragile and insecure". Running it on a production network is unsafe.
## Goal
Run a Qwen3.6-27B Q8 model (about 29 to 32 GB of weights) across two
machines using llama.cpp RPC pipeline parallelism. Node A is an NVIDIA
desktop with an RTX 3090. Node B is a Strix Halo NUC (Ryzen AI MAX+ 395,
Radeon 8060S). Use the largest context that fits on both nodes together.
## How the Split Works
```mermaid
graph LR
subgraph NodeA[NVIDIA Desktop — HEAD]
A1[llama-server<br/>--model 27B-Q8.gguf<br/>--rpc nodeB:50052]
end
subgraph NodeB[Strix Halo NUC — WORKER]
B1[ggml-rpc-server<br/>--host nodeB --port 50052<br/>--device CUDA0? no — ROCm]
end
A1 <-->|hidden states over ethernet| B1
```
Node A runs the head `llama-server`. Node B runs `ggml-rpc-server`, which
exposes its GPU as a remote device. The head splits weights and KV cache
across its own GPU and the remote device in proportion to free memory.
Each token generation passes the hidden state once across the boundary.
Key facts that shape the scripts:
- Both nodes must run the exact same llama.cpp build tag. Version skew
hangs the handshake.
- The head build needs its backend plus RPC. The worker build needs its
backend plus RPC. CUDA and ROCm do not mix inside one binary; each node
uses its own backend.
- Speculative decoding runs on the head. The draft model loads on the head.
- The model file must be present on every node with the same bytes.
## File Layout
```
pipeline-pp/

## Build Script
File: `build.sh`
```bash

# node's own backend enabled. Educational only. Do not run in production.
set -euo pipefail

cmake --build "$LLAMA_DIR/build-pp" --config Release -j
# Expected binaries: build-pp/bin/ggml-rpc-server, llama-server, llama-cli
```
Notes: the HEAD does not need a GPU if you offload everything to RPC
workers. Keep the head on the NVIDIA desktop so it can also use its local
3090 for part of the split.
## Worker Script (Node B, Strix Halo NUC)
File: `workers/worker-strix.sh`
```bash
#!/usr/bin/env bash
# Expose the Strix Halo GPU as an RPC device for a remote head.
# Educational only. Do not run on an unprotected network.
set -euo pipefail
BIN=/home/dank/llama.cpp/build-pp/bin
# Bind to the LAN address. The default binds 127.0.0.1 only.
HOST=192.168.0.143 # the Strix Halo NUC address
PORT=50052
# -c enables a local model-file cache so the split load runs once, not per boot.

# Use --device to name the backend device explicitly if auto-detect fails:
# ggml-rpc-server --host $HOST --port $PORT --device gfx1151
```
Security note: `ggml-rpc-server` exposes all memory to any client that can
reach the port. Keep it on a trusted LAN. Do not bind it to the public
internet.

### Spec Variant Summary
| Variant | draft model file | --spec-type | Notes |
| ------- | ---------------- | ----------- | ----- |
| MTP | `Qwen3.6-27B-MTP-ONLY-Q4_K_M.gguf` (~3B) | `draft-mtp` | Parallel-safe, best in benchmarks |
| DFlash | `Qwen3.6-27B-DFlash-Q8_0.gguf` | `draft-dflash` | Known premature-EOS bug |
| ngram-mod | none (built-in) | `ngram-mod` | Zero VRAM cost |
| DSpark | vLLM only | (not in llama.cpp) | Use vLLM PP instead; see below |
DSpark does not exist in llama.cpp. It is a vLLM sparse-attention draft. If
you want DSpark, use vLLM pipeline parallelism, which has its own limits
(no spec decode with PP as of 0.15.x). The llama.cpp path here covers
MTP, DFlash, and ngram-mod.
## Verify (Node A)
File: `head/verify.sh`
```bash
#!/usr/bin/env bash
# Check the split model is up and that both nodes are in the split.
set -euo pipefail
PORT=7770
# Health must return "ok" after model load (minutes, not seconds).
curl -sf "http://127.0.0.1:$PORT/health"
echo
# Show the device split from the server log.
curl -sf "http://127.0.0.1:$PORT/props" | head -40
# Expected: the model and KV cache distributed across CUDA0 (node A)
# and the remote RPC device (node B).
```
## Context Sizing Math
The model is about 29 to 32 GB. The two machines give about 51 GiB of
usable memory. That leaves about 20 to 22 GiB for KV cache. The
Qwen3.6-27B KV cache costs about 85 to 100 KiB per token at q8_0 K /
f16 V. The budget therefore gives a pool of roughly 200k to 260k tokens.
A single 262144-token slot is the practical ceiling for this split.
To run more context, shrink the model quantization. Q6_K (about 24 GB)
frees several GB for KV. Do not try to run the 96 GiB driver figure on the
Strix Halo as real memory. It is an overcommit ceiling; the physical RAM
is 30 GiB.
## What This Does Not Cover
- The remote draft-model-over-RPC path is not confirmed. The draft stays
on the head.
- `--tensor-split` is available to force a manual layer split. The sample
uses the automatic proportional split.
- RDMA (RoCEv2) transport exists but needs a compatible NIC. It adds a few
percent over TCP.

# Pipeline Parallelism
This section covers running one large model across two machines. It focuses
on pipeline parallelism (layer split) over ethernet. The research answers
what speeds are possible and which tools work. The sample scripts show a
two-node Qwen3.6-27B Q8 split for reading only.
## Terminology
Pipeline parallelism (PP) splits model layers across machines. Each machine
computes its layers and passes hidden states to the next machine. Tensor
parallelism (TP) splits each layer across machines and requires an
all-reduce per layer. PP is the only realistic option over ethernet.
Speculative decoding is a separate feature. It uses a small draft model (or
n-grams) to propose tokens that the main model verifies in one pass. It can
run together with PP in llama.cpp.
## The Two Runtimes
```mermaid
graph LR
subgraph llamaRPC[llama.cpp RPC]
A1[ggml-rpc-server on node B] --> A2[llama-server on node A<br/>--rpc nodeB:50052]
end
subgraph vllmPP[vLLM PP]
B1[vllm serve node 0<br/>tp=1 pp=2 rank 0] <-->|hidden states| B2[vllm serve node 1<br/>tp=1 pp=2 rank 1]
end
```
- [[llama.cpp RPC]] — the working, production-capable path for two
heterogeneous nodes over ethernet.
- [[vLLM Pipeline Parallelism]] — supported but heavier; needs Ray or
multiprocessing and does not compose with speculative decoding yet.
## What the Research Found
- [[Ethernet Bandwidth Math]] — a PP boundary moves only the hidden state
(about 10 KiB per token for a 27B model). 1 GbE supports hundreds of
tokens per second on paper; the real limit is latency and RPC overhead.
- [[Mixed-Vendor Experiments]] — NVIDIA + Strix Halo multi-node inference
works today via llama.cpp RPC with separate CUDA and ROCm builds. The
exact NVIDIA-desktop + Strix-Halo-NUC pair has not been benchmarked with
published numbers yet.
- [[Qwen3.6 27B Spec Methods]] — Q8 GGUF variants, and which speculative
methods (MTP, DFlash, ngram-mod) work with RPC. DSpark is vLLM-only.
- [[Expected Performance]] — estimated tokens per second for a 27B Q8 split
across an RTX 3090 and a Strix Halo NUC over 1/2.5/10 GbE.
## Deployment
- [[Qwen3.8 PP Deployment]] — the real Qwen3.8-27B split: head on Dankclaw
(Strix), worker on Dankserver (RTX 3090), b10433 on both sides, scripts in
`scripts/`, morning-of test runbook. Verified gotchas: no `--device` with
`--rpc`, default split is proportional to reported free memory (pin 1,1),
the iGPU side defaults to the ROCm backend.
## Sample Scripts
- [[Sample Script Set]] — a two-node llama.cpp RPC split of
Qwen3.6-27B-Q8_K_P with MTP, DFlash, and ngram-mod variants, sized for
the largest context that fits. For educational reading only. Do not run
it in production.

# RAM CPU Offloading in vLLM
## Overview
Stock vLLM offloads **KV pages**, not weights: the scheduler moves KV cache between GPU
and CPU. That is the upstream behaviour and it is NOT the whole story on our hosts — the
tcclaviger/R4D fork ran a real **weight** offload (`--enable-expert-offload`, tiered
expert placement, a pinned host pool per rank), which is how a 147 GiB MoE served from a
246 GiB box: [[RDNA4 MoE Expert Offload VRAM Budget]] and the tcclaviger era row of
[[frank-archon]]. First-hand in-repo evidence outranks a generic upstream claim about our
own hosts ([[Model Swap and Rollback]] §10).
> **Verified 2026-10-19 against `vllm/config/cache.py` on `main`:** there is no
> `swap_space` field — `--swap-space` is gone from current engine args. CPU KV offload is
> `--kv-offloading-size`, and it activates **only** together with `--kv-offloading-backend`
> (default `native`); both fields live in that one file. This page is the fleet's owner of
> that knob contract — other pages link here instead of restating it.
## How CPU Offloading Works
VLLM manages KV cache as pages. Each page holds attention key and value tensors for a set of tokens. When GPU memory is full, VLLM can move pages to CPU memory or disk swap space.
The KV cache swap mechanism works as follows:
1. VLLM allocates GPU blocks for active KV cache pages
2. When GPU blocks are exhausted, VLLM swaps inactive pages to CPU
3. Swapped pages are stored in a CPU memory buffer
4. When a swapped page is needed, VLLM loads it back to GPU
5. If CPU buffer is full, pages are written to disk swap space
## Key Parameters
### gpu_memory_utilization
This parameter controls the fraction of GPU memory used for KV cache.
| Value | Description |
|-------|-------------|
| 0.7 | Uses 70% of GPU memory for KV cache |
| 0.8 | Uses 80% of GPU memory for KV cache |
| 0.92 | Uses 92% of GPU memory for KV cache (default) |
| 0.95 | Uses 95% of GPU memory for KV cache |
Lower values leave more GPU memory for model weights. Higher values allow more concurrent requests but increase swap frequency.
### swap_space (removed) / kv-offloading-size + kv-offloading-backend (current)
`--swap-space` no longer exists in current engine args (verified above); the live pair is
`--kv-offloading-size` with `--kv-offloading-backend`, and offload stays off until the size
is set. The table below is the historical `--swap-space` sizing guidance, kept as a sizing
reference only.
| Value | Description |
|-------|-------------|
| 0 | No CPU swap space |
| 4 | 4 GiB swap space (historical default) |
| 8 | 8 GiB swap space |
| 16 | 16 GiB swap space |
| 32 | 32 GiB swap space |
| 64 | 64 GiB swap space |
The swap space acts as an extension of GPU memory. When GPU blocks are full, VLLM moves KV cache pages to swap space.
### max_model_len
This parameter sets the maximum context length.
| Value | Description |
|-------|-------------|
| auto | VLLM calculates optimal length |
| 2048 | 2048 tokens |
| 4096 | 4096 tokens |
| 8192 | 8192 tokens |
| 32768 | 32768 tokens |
Smaller values reduce memory usage but limit context length.
### max_num_batched_tokens
This parameter sets the maximum number of tokens per batch.
| Value | Description |
|-------|-------------|
| 2048 | Default for online serving |
| 4096 | Moderate batch size |
| 8192 | Large batch size |
| 16384 | Very large batch size |
### max_num_seqs
This parameter sets the maximum number of sequences per batch.
| Value | Description |
|-------|-------------|
| 128 | Default for online serving |
| 256 | Large batch |
### kv_cache_dtype
This parameter sets the KV cache data type.
| Value | Description |
|-------|-------------|
| auto | Uses model default dtype |
| fp8 | Uses FP8 for KV cache (reduces memory by 50%) |
| fp8_e5m2 | Uses FP8 E5M2 format for KV cache |
## Memory Configuration Examples
All three examples carry the retired `--swap-space` syntax and are kept as sizing
references; the live knob pair is named above.
### Small Model on Single GPU
```
vllm serve Qwen/Qwen2.5-1.5B-Instruct \
--gpu-memory-utilization 0.9 \
--swap-space 4 \
--max-num-batched-tokens 4096 \
--max-num-seqs 128
```
### Large Model with CPU Offload
```
vllm serve meta-llama/Llama-3.1-70B-Instruct \
--tensor-parallel-size 4 \
--gpu-memory-utilization 0.8 \
--swap-space 16 \
--max-model-len 8192
```
### Memory-Constrained GPU
```
vllm serve meta-llama/Llama-3.1-70B-Instruct \
--tensor-parallel-size 4 \
--gpu-memory-utilization 0.7 \
--swap-space 32 \
--max-model-len 4096 \
--max-num-batched-tokens 2048
```
## Preemption Modes
VLLM uses two preemption modes when GPU memory is insufficient:
### Recompute Mode (Default in V1)
VLLM recomputes the prefill for preempted requests. This uses GPU compute instead of memory. This is the default mode in VLLM V1.
### Swap Mode
VLLM swaps KV cache pages to CPU and reloads them later. This uses CPU memory instead of compute.
## Monitoring
Watch for preemption warnings:
```
WARNING scheduler.py: Sequence group 0 is preempted by PreemptionMode.RECOMPUTE mode because there is not enough KV cache space.
```
If you see frequent preemptions:
1. Increase `gpu_memory_utilization`
2. Raise the KV offload budget (`--kv-offloading-size`, with `--kv-offloading-backend`)
3. Decrease `max_num_seqs`
4. Increase `tensor_parallel_size`
5. Increase `max_model_len` to match actual usage
## Memory Conservation Tips
- Use quantization (FP8, INT8) to reduce model size
- Reduce `max_model_len` to match actual needs
- Reduce `max_num_seqs` to limit concurrent requests
- Disable CUDA graphs with `--enforce-eager` to save memory
- Set `compilation_config.cudagraph_capture_sizes` to smaller values
- Set `--kv-cache-memory-bytes` to pin the KV budget instead of letting the profiler guess
(the flag our own `scripts/patches/gpu_worker-kv-cap.patch` reads)
- Limit multi-modal inputs with `limit_mm_per_prompt`
## Environment Variables
| Variable | Description | Default |
|----------|-------------|---------|
| vLLM_CPU_KVCACHE_SPACE | KV cache space in GiB for CPU backend | 4 |
| vLLM_CPU_OMP_THREADS_BIND | CPU thread binding for OpenMP | auto |
| vLLM_CPU_NUM_OF_RESERVED_CPU | Reserved CPU cores per rank | 0-1 |
| vLLM_CACHE_ROOT | torch.compile cache directory | ~/.cache/vllm |

# RDNA4 Container Serving
Bring-up path for Dankserver (2x Radeon AI PRO R9700, gfx1201 — card count,
per-card VRAM and host RAM are [[Dankserver System Specs]]'s) with
`docker.io/tcclaviger/vllm` (vLLM 0.29.0.dev, GLM/Qwen-specialised RDNA4 build
with native MoE quant kernels and a first-class expert offload planner). The
tuning history and current deployed shape live in
[[frank-archon]]; this page is the bring-up law.
## 0. Know the box — and its phantom third GPU
`torch.cuda.device_count()` returns **3**; summing `total_memory` overstates
the box as 186.7 GiB. The third device is the 7700X's integrated Vega
(gfx1036): torch reports ~123 GiB for it, `rocm-smi` reports 0.50 GiB,
allocating on it moves system `MemAvailable` 1:1 (it is GTT over DDR5, not
dedicated VRAM), and it dies with `hipErrorInvalidKernelFile` when the image
ships no code for that arch. **Never sum device `total_memory`; never count
the iGPU as headroom or a workload.**
## 1. Preflight: is the quant class EXECUTABLE, not merely present?
Expert offload is mandatory when weights exceed VRAM, and it requires the
checkpoint's experts class to have BOTH a compiled kernel AND an
`offload_recipe` ("a pinned expert has no host copy, so there is no
read-through fallback" — startup aborts otherwise). Check BEFORE downloading
anything:
```bash
podman run --rm --device /dev/kfd --device /dev/dri --device /dev/mem \
-e HIP_VISIBLE_DEVICES=0,1 --entrypoint bash $IMAGE -c '
nm -D /app/r4dhip/r4d.so | grep -oE "gemm_moe_[a-z0-9_]+" | sort -u
grep -rl offload_recipe /opt/vllm/lib/python*/site-packages/vllm/model_executor/layers/fused_moe/'
```
| quant | kernel in `r4d.so` | experts class | verdict |
|---|---|---|---|
| FP8 | yes | `Fp8HipMoEExperts` | **serves** |
| MXFP4 / DSFP4 | yes (`gemm_moe_mxfp4a8_*` / `dsfp4a8_*`) | `R4dMxfp4MoEExperts` / `R4dDsfp4MoEExperts` | **serves** |
| W4A16 | **no** `gemm_moe_w4a16_*` | `R4dW4a16MoEExperts` exists | silently falls back to generic `TritonWNA16Experts`, no recipe → startup halts |
| RFA | none | no class at all | out |
Also confirm the architecture routes natively with NO overlay
(`ModelRegistry.get_supported_archs()` for `Qwen4Exp`/`Glm5`). The stock image
natively carries Qwen3.8/Qwen4Exp and GLM-5.x including MTP heads. **Do not
apply vendor overlays** against a fast-moving pre-release image — the breakage
misleads (a missing symbol in the overlay's OWN copy of a module masks the
real cause, then moves to another symbol each patch;
`cannot import name 'checkpoint_has_lm_head'` = overlay clobbered
`transformers_utils/config.py`). The image ships quantizers for
`rfa|rfi|mxfp4|mxfp4ocp|paro5` under `/app/tools/quantize.py`
(`--fp8-attn --quant-only --dry-run` first) if a re-quant is needed — note it
can run MXFP4/DSFP4/FP8 but only PRODUCE rfa/rfi/mxfp4/paro.
## 2. Fetch with verification, always
Gated repos: token never in argv (`pgrep -a curl` prints command lines).
Build a mode-600 curl config once:
```bash
{ printf 'header = "Authorization: Bearer '; cat ~/.cache/huggingface/token; printf '"\n'; } \
> ~/.cache/huggingface/curl.conf && chmod 600 ~/.cache/huggingface/curl.conf
curl -K ~/.cache/huggingface/curl.conf -f -sS -L -C - -o "$out" "$url"
```
`--fail` is MANDATORY — `curl -o FILE URL` exits 0 on HTTP 401/403 and writes
the error body as a "successful artifact" (a gated repo once yielded three
153-byte shards with identical sha256s and a cheerful DONE banner). `-C -`
resumes torn shards; HTTP/2 cancels leave silently truncated files, so
re-verify EVERY shard's byte count against the Hub manifest (and the LFS
sha256) before serving. The AGENTS.md Secret Rules carry the token-hygiene
law; [[frank-medium-model-swap]] has the same detail for GGUFs and
`.partNofM` fragments.
## 3. Serve — the known-good invocation and its traps
```bash
sudo sh -c 'sync; echo 3 > /proc/sys/vm/drop_caches'
podman run -d --name <ctr> --ipc=host --ulimit memlock=-1:-1 \
--cap-add SYS_PTRACE \
--device /dev/kfd --device /dev/dri --device /dev/mem \
-e HIP_VISIBLE_DEVICES=0,1 -e VLLM_ROCM_USE_AITER=0 \
-v /home/dank/models/<model>:/models:ro \
$IMAGE /models --served-model-name <name> --port 7770 \
--tensor-parallel-size 2 --max-model-len 65536 \
--kv-cache-memory-bytes 2147483648 \
--max-num-seqs 4 --gpu-memory-utilization 0.95 \
--enable-prefix-caching --trust-remote-code
```
- **Entrypoint already execs `vllm serve "$@"`** — pass the model path as the
first argument and do NOT pass `serve` (podman then tries to pull `serve`
as an image name). `-e VAR=1` must come BEFORE the image name.
- **Mount the whole `/dev/dri`, never individual render nodes** (§4).
- `--ipc=host` and `--shm-size` are mutually exclusive in podman.
- `podman run -d` without `-a` sends container stdout nowhere — read
`podman logs <ctr>`; and vLLM writes `Application startup complete` to
**stderr**, so a `podman logs X 2>/dev/null | grep -q` readiness gate never
fires.
- Start at 65536, not the native ceiling; prove the plan, then scale.
- Load takes ~5 min with `/health` refusing the whole time — do not kill the
process (deploy.sh waits 20 min).
## 4. Container GPU-init triage (ordered)
1. **Enumerate-vs-context trap (most common):** individual
`renderD*` nodes give HIP the render nodes WITHOUT the primary `card*`
nodes — it enumerates agents (`device_count()` returns N) and then refuses
every context: `RuntimeError: No CUDA GPUs are available` on the first
real op. A/B-confirmed 2026-09-19. Rule: `--device /dev/kfd --device
/dev/dri --device /dev/mem`; restrict GPUs with `HIP_VISIBLE_DEVICES`,
never with device nodes.
2. **`device_count()` is not evidence.** Prove usability with a real op
(`(a@a).sum().item()` on a fresh `torch.randn`), then repeat via
`mp.spawn`, `mp.fork`, and `subprocess.run([sys.executable, ...])`, and
cross-check `rocm-smi --showmeminfo vram`.
3. **memlock rlimit → a MISLEADING CUDA OOM.** Host default 8192 KB; a pin
larger than the limit fails as
`torch.AcceleratorError: CUDA error: out of memory` raised from
`pin_memory()` — it names the accelerator but the fault is host pinned
memory. It cannot be raised from inside a container or even from root's
own shell (`Operation not permitted`); only PAM applies it at login, so
fixes only affect NEW sessions:
`/etc/security/limits.d/99-memlock.conf` with
`* - memlock unlimited` + `root - memlock unlimited`; the container needs
`--ulimit memlock=-1:-1` to inherit. Discriminating test after the fix:
the container reports `unlimited` AND small pins succeed; if pins still
fail, memlock was never the cause.
4. **`/proc/meminfo` TAB trap:** the key/value separator is a TAB, so
`grep MemAvailable /proc/meminfo | tr -s " " | cut -d" " -f2` returns
EMPTY and a following awk prints `0.0` — a false "host out of memory" on a
host with hundreds of GiB free, which invites aborting something healthy.
Tab-safe: `awk -v k='MemAvailable:' '$1==k {printf "%.1f", $2/1048576;
exit}' /proc/meminfo`, cross-check `<= MemTotal`, refuse to print a zero.
Use `scripts/dankstatus.sh` instead of hand-rolling.
5. **Silent-parse traps:** `grep -c PATTERN file || echo 0` yields TWO lines
(grep prints 0 AND exits 1) — `[: 0\n0: integer expected`; use
`| head -1` or `|| true`. `systemctl is-enabled` can emit multiple lines.
`rocm-smi --showmeminfo vram --csv` column order is `device, VRAM Total
Memory (B), VRAM Total Used Memory (B)` — reading $3 as total/$4 as used
yields 0.00; filter to `^card[0-9]+$`.
6. **Guard the box:** long loads with co-tenants can drive RAM to 0 — abort
before the OOM killer (`MemAvailable < 4 GiB → podman rm -f`, exit 1).
7. **Drop page cache before a large load** (`echo 3 > /proc/sys/vm/drop_caches`)
and confirm the drop was actually in effect for the run before treating a
failure as a capacity wall — a stale "it doesn't fit" from a contaminated
run is expensive to unwind.
## 5. Memory budgeting: the levers are not where they look
Every figure in this section is a tcclaviger-era boot on the port that is
[[frank-archon]]'s today; the laws they teach are general. The planner builds
`budget = total × util`, subtracts a KV reserve, and gives
the REMAINDER to the expert arena. Consequences, all measured:
- **`--gpu-memory-utilization` grows the ARENA, not the KV pool** (KV stayed
0.64 GiB at util 0.95 and 0.98). The arena is the only elastic term.
- **Lowering `--max-model-len` is the WRONG lever and backfires:** a smaller
context shrinks the reserve, handing the space to the arena — measured 65536
→ 0.64 GiB KV, 32768 → 0.34 GiB KV.
- **Hybrid-attention undercount:** the planner's per-token KV figure for
Qwen4Exp is an undercount — the printed figure and the true one are both on
[[frank-archon]] — because it misses the large fixed per-sequence Mamba state
(~2x), so the reserve is always short and the arena silently covers it.
Fix by pinning the pool: `--kv-cache-memory-bytes <BYTES>` (era reading: a
2 GiB pin = 113,595 tokens ≈ 3.47x concurrency at 32k — that pair is this
page's record of the tcclaviger boots, not [[frank-archon]]'s). For long
context,
`--kv-offloading-size` (GiB) spills KV to host.
- **`--expert-offload-mem` caps the HOST side, not the VRAM arena**
(`cap = int(x * GIB)` against `host_memory_available()`). Do not reach for
it to fix a VRAM problem; to grow the arena, shrink the KV pin or raise
util (see [[frank-archon]] for the
util=1.0 unbootability law).
**Read the plan — it is the real acceptance test:**
```
expert offload: AUTO-ENABLED, weights 62.54 GiB per rank exceed the 30.27 GiB budget (TP2)
budget (total x util) 30.27 GiB
non-expert weights 6.28 GiB
KV reserve 0.36 GiB <- sanity-check against the model's own per-token figure
CUDA graphs 0.66 GiB
runtime overhead 7.60 GiB
expert cache space 15.36 GiB 6712 slots of 2.344 MiB
host-backed experts/rank 52.74 GiB 23040 experts
host: 105.48 GiB across 2 ranks of 160.89 GiB usable
```
Host fits when `host_total < usable`. The PLE n-gram table rides memfd and is
SHARED across TP ranks.
**Loading mechanism** (for reasoning about peak RAM): weights never materialise
in VRAM — expert Parameters start as CPU staging tensors; each layer's
`weight_loader` counts shard events and, on layer completion,
`ExpertTopology.split_layer` moves that layer's experts into the VRAM arena
and compacts the rest into exact-size pinned host tensors behind UVA. Peak
host RAM = `host-backed set + layers still loading`, not the whole model. At
runtime `apply_hot_cold` sends arena-resident experts down a hot GEMM and the
rest straight over PCIe via UVA views — no staging copy in the critical path.
**Emulation check:** a dequantize-to-compute path doubles real host RAM — the
measured pair (offload request vs host footprint) is on [[frank-archon]] — and
the doubling is invisible in the weight count. Read the log for `Using
'EMULATION' Mxfp4 MoE backend` before concluding "doesn't fit".
## 6. Performance profile and honest measurement
Decode on this pair is **PCIe-gather-bound, context-independent**: the rate is
flat from a few hundred to sixteen thousand context tokens, so KV attention is
not the cost (the flat figure and its MTP/gather deltas are
[[Tcclaviger Fork Ops]]'s profile of the same shape). With ~29 % of experts
arena-resident, under a gigabyte crosses PCIe per token at the engine's
effective read rate; cold-vs-warm differing ~10 % confirms the LRU works;
growth is linear in hit rate, and only speculative decode cuts sequential STEPS
rather than making each cheaper.
**Benchmark traps that produced fake numbers here:**
- `max_tokens=1` is not TTFT (the server can satisfy it without doing the
work — prefill looked flat at 1.26 s for 16k AND 30k prompts). A 64-token
non-streamed reply is time-to-64-tokens (decode-bound, flat ~9.6 s at every
length). Correct TTFT: stream and time the FIRST content-bearing chunk.
- A small repeating word loop is prefix-cacheable AND n-gram-predictable — a
43-word cycle reported 22,897 tok/s prefill, almost entirely cache hit. Use
a large vocabulary in shuffled order and print `cached_tokens`.
- ~1.2 s fixed per-request overhead swamps prefill below ~16k tokens; compare
prefill at 30k+ only.
- Size prompts with `/v1/messages/count_tokens` (a chat call for counting
pollutes the metric); guessing words-per-token silently overran the window
(HTTP 400).
- Always run a canary: plant a unique token at the END of a long prompt and
ask the model to quote it — proves prompts reach the model at all.
- Measure warm AND long (`podman exec` + urllib at 127.0.0.1:7770): a 33-token
reply read 14.6 cold / 20.3 warm; a 768-token generation hit 25.7; two
concurrent streams scaled to 47 aggregate.
**Levers (all opt-in):** `--expert-prefetch N` takes an INT depth, not a
boolean (default 0; at depth 1 only ~10 % cold-vs-warm difference — the cache
already works); `CLAV_TUNABLEOP_SWEEP=1` autotunes GEMM shapes (silently
skipped under expert offload unless `CLAV_TUNABLEOP_WITH_OFFLOAD=1` too —
see [[frank-archon]] for why it was rejected);
`--expert-precise-memory` swaps the fitted overhead figure in.
