# Server App Configs

Podman deployment configuration for two homelab servers: Dankserver and Dankclaw.

This repository is the single source of truth for both hosts. It tracks the
container stacks and the LLM inference fleet. Edits flow through this repo,
then deploy to the targets with `scripts/deploy.sh` (one script per target
covers both workloads).

> 2026-08-22: the former `vllmScripts` repository (LLM fleet) is merged
> into this repo with its full git history. Its knowledge base now lives at
> [serverAppConfigs-docs/LLM/index.md](LLM/index.md).

### Deployment and Topology

- [[deployment]] — unified deploy and update process for both servers
- [[frank-redo-2026-08-17]] — the 2026-08-17 topology change
- [[frank-primary-llamacpp-qwen38-flash-next-q8]] — the ACTIVE
  frank-primary runbook: unsloth llama.cpp (b11030-mix prebuilt, ROCm
  gfx120X, root unit) serving unsloth Qwen3.8-Flash-Next at Q8_0 (175.3
  GiB) on Dankserver's both R9700s — the shared Q8_0 MTP head chained
  behind ngram-mod, BF16 vision, the experts and the 51B n-gram table
  computed in host RAM, the placement law, the cutover, and the rollback
- [[frank-primary-lucebox-ds4]] — RETIRED 2026-09-26 (same-day swap;
  rollback target): the Lucebox runtime serving
  DeepSeek-V4.1-Flash-ROCMFP23 (377.2 GiB GGUF, 43-layer MoE, 256 routed
  experts top-6) on Dankserver's R9700 with the routed experts computed
  on CPU from the mmapped page cache — held :7770 for hours
- [[frank-medium-radiance-mxfp4]] — RETIRED 2026-09-26:
  vllm-radiance as ONE tensor-parallel process (TP=2 over the R4D one-shot
  allreduce) serving just1moremodel/Qwen3.8-27B-Uncensored-MXFP4-awq (MXFP4
  W4A8, DFlash2 drafter, unquantized bf16 KV since 2026-09-21) on Dankserver's
  2x Radeon AI PRO R9700 behind the :7770 endpoint — the quantization-aware
  entrypoint, the three-arm battery that chose TP=2, verified capabilities,
  and the record of the 2026-09-16 two-replica era
- [[frank-medium-model-swap]] — how to swap the checkpoint behind frank-medium:
  the streamlining toolchain (hf-manifest.py, hf-fetch.sh,
  swap-frank-medium.sh), the quantization-aware entrypoint contract, the
  quadlet edit, the deploy, the capability battery, and the rollback path
- [[frank-medium-llamacpp-dflash2]] — RETIRED 2026-09-16 → 2026-09-20:
  mainline llama.cpp (gfx1201 HIP build) serving orcarouter Qwen3.8-27B at
  Q8_0 with the DFlash2 drafter as ONE layer-split process (32:33, two
  163,840-token slots); holds the batch/ubatch optimum curve and the
  per-layer split arithmetic the rollback recipe points back to
- [[Dual-R9700-Cooperation]] — whether the two R9700s can run ONE model: the
  RCCL/PCIe-atomics evidence on the old TUF GAMING B650-E (which closed tensor
  parallelism too), what the 2026-09-20 ProArt B850-Creator x8/x8 swap changed
  — both chains `Routing+`, both endpoints `ReqEn+` — and the measured
  three-way verdict: radiance TP=2 won and is the deployed shape
- [[frank-medium-rocmfpx]] — PRIOR frank-medium deployment (llama.cpp era):
  charlie12345/ROCmFPX serving kingjones777/
  Qwen3.8-27B-ROCmFPX-Q8_0-AGENT-GGUF; kept as the record of the runtime it

  DFlash2 Q4_K_M drafter (depth 4) on the gfx1151 iGPU — one 262,144-token
  conversation, q8_0 KV (the build lacks fp8), text-only, Qwen-Sharp v22.4.0
  template, the 114 GiB GTT memory model, client contract
- [[frank-large-kairic-edge-qwen38-27b]] — RETIRED 2026-09-21 (replaced by
  [[frank-large-unsloth-qwen38-27b-q8xl]]; same-day swap): the Kairic Edge

  iGPU — one 262,144-token conversation, native MTP depth 4 + n-gram
  drafting, compatibility mode, the 114 GiB GTT memory model, client contract
- [[frank-large-unsloth-qwen38-flash-next]] — RETIRED 2026-09-21 (replaced by
  [[frank-large-kairic-edge-qwen38-27b]]; same-day swap): the unsloth

  unsloth/Qwen3.8-Flash-Next-GGUF:UD-IQ4_XS (a 125B MoE / 6B active) on the

  explicit -md shared-Q8_0 head, the 114 GiB GTT memory model, client contract
- [[frank-large-ciru-orca]] — RETIRED 2026-09-21 (replaced by

  262,144-token conversation, MTP depth 4, 4096 MiB PLE cache, runtime-root
  gate, client contract
- [[halogen-flash-server]] — RETIRED 2026-09-19 (replaced by
  [[frank-large-ciru-orca]]; rollback target, 2026-09-16 → 09-19):
  peonist-ai/halogen-flash-server 0.5.8 serving peonist-ai/halogen-qwen3.8-
  flash-next (w4b `.hgn` + quality overlay) on the gfx1151 iGPU — two 200k
  conversations over one 400,384-position pool, deployed flags, memory model,
  client contract
- [[frank-large-ik-uncensored]] — the RETIRED 2026-09-16 frank-large runbook
  and rollback target (2026-09-15 → 09-16): ik_llama.cpp serving
  mradermacher/Qwen3.8-Flash-Next-Uncensored-i1-Q4_K_M on the RTX 3090 +
  Strix Halo hybrid — its measured envelope is why the fleet went back
- [[dankclaw-iommu-translation-off]] — why Dankclaw boots with
  `amd_iommu=off` since 2026-09-11 (13-16 % prefill), what it cost
  (the NPU endpoint), and how to revert
- [[kingjones-strix-rocmfp4]] — the PRIOR frank-large runbook
  (2026-08-30 → 2026-09-11) and the rollback target:
  kingjones777/Qwen3.8-Flash-Next-ROCmFP4-STRIX-GGUF on the card's
  pinned kingjones30/ROCmFPX build
- [[kingjones-q8agent-rocmfpx]] — the retired Q8_0-AGENT investigation and `set_rows` failure

- [[kingjones-strix-mtp]] — the kingjones Qwen3.8-27B ROCmFP4 STRIX MTP model on Dankclaw (active)
- [[dealign-ornith-crack]] — the retired Ornith-1.5-35B-A3B CRACK model on Dankserver (retired 2026-09-02)
- [[frank-small-gemma4-12b]] — the ACTIVE frank-small runbook since
  2026-09-17: mainline llama.cpp serving
  HauhauCS/Gemma4-12B-QAT-Uncensored-HauhauCS-Balanced at Q4_K_M
  (MTP assistant sidecar + ngram-mod, q8_0 KV, --fit → 262k) on
  Dankclaw's RTX 3090, port 7771
- [[frank-small-vllm-gemma4]] — RETIRED 2026-09-19 (same-day revert,
  rollback target): vLLM serving google/gemma-4-12B-it-qat-w4a16-ct (w4a16
  Marlin) with the bf16 MTP assistant on the RTX 3090 — bf16 KV, 289,647-

- [[Dankclaw Improvements]] — host-level changes on the Strix Halo box
- [[Swap Configuration]] — the 64 GiB `/swap.img` host swapfile (raised from
  8 GiB 2026-09-12): fstab-driven `swap.img.swap` unit, the safe resize
  ordering that drains the old file into fresh swap instead of into a host
  whose `MemAvailable` lies by the size of the model, and the swappiness caveat
- [[frank-npu]] — the RETIRED FLM NPU endpoint on Dankclaw (2026-09-11):
  Gemma4 E4B vision+audio pack on the XDNA2 NPU, port 7771; kept as the
  retirement record, including the IOMMU/SVA err=-19 root cause and
  where every dependent route moved

### Benchmarks and Sizing

- [[frank-large-benchmark]] — backend/spec benchmark behind the old head
- [[ubatch-benchmark-large]] — active-model llama-bench ubatch sweep plan and results
- [[frank-small-benchmark]] — the small-model benchmark suite
- [[frank-medium-batch-ubatch]] — the 2026-09-16 batch/ubatch sweep on the 2x
  R9700 layer split: prefill PEAKS at ubatch 512 and falls on both sides, the
  logical batch buys nothing measurable, decode never moves, and the ubatch's
  uneven VRAM give-back (1.30 GiB on card 0 against 2.41 GiB on card 1) moved
  the tensor split from 36:29 to 35:30
- [[Running Qwen3.6 35B A3B FP8 on Dankserver]] — Qwen3.6-35B-A3B hardware notes
- [[Running Qwen3.6 27B FP8 on Dankclaw]] — Qwen3.6-27B sizing on the iGPU
- [[qwen3.8-strix-optimizations]] — Strix Halo tuning notes
- [[x4-pair-experiment]] — what a 3090 + Strix Halo combination can and cannot
  do in mainline llama.cpp (measured 2026-09-16): the tensor inventory that
  decides a split, the one flag (`-ot`) that kills per-tensor placement across
  devices, the two-device layer splits that DO work (pure-Vulkan and cross-vendor
  CUDA+Vulkan, +7 % decode at 64k), and the harness-parsing trap that made the
  first round of measurements say otherwise
