LLM Fleet — Knowledge Base

Documentation for the LLM inference fleet on the two hosts (2026-10-01): Dankserver runs the tcclaviger RDNA4 vLLM fork on frank-primary (the digest-pinned tcclaviger/vllm image driving podman run directly, serving orcarouter/Qwen3.8-Flash-Next-Uncensored-FP8 across both Radeon AI PRO R9700s on :7770, TP=2 with automatic tiered-expert offload, 4 seqs x 262144 ctx (the model's full native window), fp8 KV (5 boot but leave no runtime headroom; 6 do not fit), no speculative decode, MNBT 1024, MoE gather 32x64, util 0.98, reasoning/tool parsers wired (qwen3 / qwen3_xml) with preserve_thinking on, measured 36.4-39.4 tok/s decode — the 2026-10-01 bf16 no-spec cutover plus the night ladder; rollback frank-primary-fp8-mtp-20261001), and Dankclaw runs two endpoints on the same arch — vLLM (digest-pinned kyuz0 TheRock gfx1151 image; frank-large, XiaomiMiMo/MiMo-V2.6-Distill-Qwen-9B in FULL BF16 with cross-model MTP spec decode from the Qwen3.5-9B head on the gfx1151 iGPU, 4 x 262144 ctx, port 7770) and SGLang (frank-small, the same model as an INT8 W8A16 AutoRound conversion on the RTX 3090, 2 x 262144 ctx, port 7771).

2026-08-22: the former vllmScripts repository is merged into the serverAppConfigs repository. This knowledge base moved from the old repo's serverAppConfigs-docs/ root to serverAppConfigs-docs/LLM/. The fleet scripts and units now live in the repo's scripts/ directory.

Active Deployment

• frank-primary-glm53-flash-w4a16 — the ACTIVE frank-primary runbook (2026-09-30, root systemd unit, port 7770): the tcclaviger RDNA4 vLLM fork (digest-pinned tcclaviger/vllm@sha256:da4029666…, plain podman run, no shim) serving Intel/GLM-5.3-Flash-W4A16-AutoRound — AutoRound symmetric int4 group 128, ~170 GiB, 34 shards + 2 extras, 113,074 tensors — on BOTH R9700s, TP=2, with the MoE experts offloaded to pinned host RAM (12,096 experts/rank, 73.64 GiB) behind a 14.51 GiB / 2,383-slot VRAM LRU arena; the MoE kernel is libr4d's grouped W4A16 GEMM (R4dW4a16MoEMethod, reached because the checkpoint's quant_method: auto-round is overridden to inc — a compressed-tensors W4A16 checkpoint of the same model has NO offload recipe and refuses to serve). 131,072 ctx x 2 seqs, bf16 KV, util 0.98, prefix caching, vision and glm47 tool/reasoning parsers, MTP OFF and prefetch OFF by measurement. Measured decode 9.9-10.0 tok/s, prefill 918 tok/s — the 35 tok/s target is NOT met, bounded by the fork's expert-gather read path (~8.2 GB/s effective vs a 22.74 GB/s link) at a 0.53-0.66 cache hit rate. Rollback: commit 2339fae (the qwen FP8 + MTP4 shape of 2026-09-29 → 09-30)
• frank-primary-r9v-radiance-qwen38-q8 — RETIRED 2026-09-30 (two swaps back; payload and R9V state dirs intact on disk, git tag frank-primary-r9v-q8-20260929 is the last pre-cutover commit): frank-primary-r9v-radiance-qwen38-uncensored — RETIRED 2026-09-27 (same-day swap to the Q8_0 payload; rollback target, state + payload intact on disk): the R9V radiance-vLLM fork serving Dyluhn/Qwen3.8-Flash-Next-Uncensored-R9V-IQ4_XS (92.39 GiB, 3 shards) + blockfp8 MTP4 (depth 4) + F16 vision on BOTH R9700s — TP=2 tiered experts (UVA pinned host copy, 62 hot + 160-slot LRU on rank 0, 428 static on rank 1), PLE n-gram on ssd-mmap, CED on, 196608 ctx. Cut over from llama.cpp the same day; rollback target frank-primary-llamacpp-qwen38-flash-next-q8
• frank-primary-llamacpp-qwen38-flash-next-q8 — RETIRED 2026-09-27 (rollback target; the llama.cpp b11030 endpoint of 2026-09-26): unsloth llama.cpp (b11030-mix prebuilt, ROCm gfx120X, bundled runtime) serving unsloth/Qwen3.8-Flash-Next-GGUF at Q8_0 across both R9700s — routed experts and the 51B-param n-gram table computed in host RAM (-ot exps=CPU,per_layer_token_embd.weight=CPU), the shared Q8_0 MTP head (depth 2) chained behind ngram-mod, BF16 vision, one full 262,144-token conversation, reasoning_content, the placement law, the cutover and rollback
• frank-primary-lucebox-ds4 — RETIRED 2026-09-26 (same-day swap, rollback target; active for hours): the Lucebox DS4.1 engine (localhost/lucebox-rocm:gfx1201) serving Lucebox/DeepSeek-V4.1-Flash-ROCMFP23 (377.2 GiB) with streamed experts — the fleet's only non-llama.cpp runtime detour
• dankserver-frontier-moe-feasibility — VERIFIED 2026-09-28: which of DeepSeek-V4.1-Flash (552B), MiMo-V2.6-Flash-MOPD (309B) and GLM-5.3-Flash (320B) can run on the 2x R9700 box, on what runtime, and why V4.1 does not fit (475 GiB payload, 189 GiB of it Engram; decode is PCIe-expert-stream bound, ~23 tok/s ceiling at today's residency). Includes the Affinity V4-Flash-to-V4.1 port assessment — reusable expert tiering, four architecture gaps, one of them a silent-wrongness trap on the Engram key
• dankserver-qwen38-fp8-expert-offload-tuning — VERIFIED 2026-09-29: the flag-level decode-tuning campaign on the ad hoc qwen-fp8 container (tcclaviger RDNA4 fork, orcarouter/Qwen3.8-Flash-Next-Uncensored-FP8, TP=2 across both R9700s). >35 tok/s MET: 37.44-40.57 tok/s with --expert-prefetch DELETED — telemetry measured the prefetcher at 36% precision, wasting ~half the gather traffic (the LRU itself runs at 82.45% hit). Prefetch-on incumbent 26.8 survived every other challenger (geometry, spec depth, TunableOp-corrupts, batch knobs, concurrency, ngram-fork-bug); the residual gap to ~60 tok/s is the fork's gather read path (6.5-9.5 GB/s effective vs 22.7 at the same slab size)
• frank-medium-radiance-mxfp4 — RETIRED 2026-09-26 (replaced by frank-primary-lucebox-ds4, then frank-primary-llamacpp-qwen38-flash-next-q8): vllm-radiance 0.9.3 serving just1moremodel/Qwen3.8-27B-Uncensored-MXFP4-awq (MXFP4/quark W4A8) with the z-lab DFlash2-FP8 drafter as ONE tensor-parallel process (TP=2) behind :7770, on unquantized bf16 KV (KV_DTYPE=auto, cut 2026-09-21). The FP8 checkpoint is the on-disk rollback. The three-arm battery that chose TP=2, the auto-sized KV pool, and the verified capability battery (tools, reasoning)
• 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. The 2026-09-20 MXFP4 → FP8 swap is the worked example
• frank-medium-llamacpp-dflash2 — RETIRED 2026-09-16 → 2026-09-20: mainline llama.cpp serving orcarouter/Qwen3.8-27B-Uncensored-GGUF at Q8_0 with the DFlash2 Q4_K_M drafter as ONE layer-split process (32:33 over two 163,840-token slots); superseded by the radiance TP=2 cutover, and the rollback target. Keeps the batch/ubatch optimum curve and the per-layer split arithmetic
• Dual-R9700-Cooperation — whether the two R9700s can serve ONE model: the RCCL/PCIe-atomics wall on the old TUF GAMING B650-E, the 2026-09-20 ProArt B850-Creator x8/x8 swap that cleared it, and the measured three-way verdict (radiance TP=2 95.8 t/s decode vs layer split 45.7 vs llama tensor mode 30.5) that put TP=2 in production
• frank-medium-rocmfpx — PRIOR frank-medium deployment (llama.cpp era, 2026-09-15): charlie12345/ROCmFPX serving kingjones777/Qwen3.8-27B-ROCmFPX-Q8_0-AGENT-GGUF; kept as the record of the runtime it replaced
• freetoken-frank-small — RETIRED 2026-09-15, when the RTX 3090 moved to frank-large: the FreeToken v0.1.2 frank-small runbook (batsclamp Huihui-Qwen3.6-35B-A3B-abliterated-FP8), kept as the retirement record. The NAME was reused on 2026-09-16 by a different service on Dankclaw — see frank-small-qwen38-gsq-rco
• freetoken-benchmark-sweep — KV pool vs decode speed sweep (bs1/bs3/bs4/bs6, 8k–700k KV) on Dankserver RTX 3090
• deployment — deploy and update process for both servers
• frank-redo-2026-08-17 — the 2026-08-17 topology change
• frank-large-vllm-mimo-v26-bf16 — ACTIVE frank-large runbook since 2026-10-01 (root systemd unit, port 7770): the digest-pinned kyuz0/vllm-therock-gfx1151 image serving XiaomiMiMo/MiMo-V2.6-Distill-Qwen-9B in FULL BF16 on the gfx1151 iGPU, 4 x 262144 ctx, with CROSS-MODEL MTP spec decode from Qwen/Qwen3.5-9B (the fleet's first; 71%/44% per-position acceptance measured) — the roof math (13.1 t/s base is ~94% of LPDDR5x BF16), the measured MTP-vs-DFlash table (19.8 vs 17.4 t/s decode), the greedy-text numerics trap, the reasoning field change, troubleshooting
• frank-large-gufo-qwen38-27b — RETIRED 2026-09-28 → 2026-10-01 (replaced by frank-large-vllm-mimo-v26-bf16; rollback target via git tag frank-large-gufo-q4kxl-20261001, engine + payload + drafter still on the host): gufo (gufo-org/gufo) v0.1.1, the Strix Halo inference engine, built from source on Dankclaw, serving Qwen3.8-27B UD-Q8_K_XL/UD-Q4_K_XL with the z-lab DFlash2 Q4_K_M drafter on the gfx1151 iGPU — the two from-source build workarounds, the client-contract delta, the measured prefill/decode trade against llama.cpp
• frank-large-unsloth-qwen38-27b-q8xl — RETIRED 2026-09-28 (replaced by frank-large-gufo-qwen38-27b; rollback target): stock llama.cpp (unsloth b11030, ROCm gfx1151) serving unsloth/Qwen3.8-27B-GGUF:UD-Q8_K_XL with the z-lab DFlash2 Q4_K_M drafter (depth 4) on the gfx1151 iGPU — one full 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, troubleshooting
• frank-large-kairic-edge-qwen38-27b — RETIRED 2026-09-21 (same-day swap, replaced by frank-large-unsloth-qwen38-27b-q8xl; rollback target): the Kairic Edge runtime (ciru-ai/ROCmFPX v1.2, built from source) serving jcbtc/Qwen3.8-27B-IU4-Kairic-Edge (IU4 W4A4, 27B dense) on the gfx1151 iGPU — one full 262,144-token conversation, MTP depth 4 + n-gram drafting, the three PromptForge sidecars, compatibility mode, the 114 GiB GTT memory model, client contract, troubleshooting
• frank-large-unsloth-qwen38-flash-next — RETIRED 2026-09-21 (same-day swap, replaced by frank-large-kairic-edge-qwen38-27b; rollback target): the unsloth llama.cpp prebuilt (b11030-mix-5ff778e, ROCm gfx1151) serving unsloth/Qwen3.8-Flash-Next-GGUF:UD-IQ4_XS (125B MoE) on the gfx1151 iGPU — one 200,000-token conversation, MTP depth 2 via the explicit -md shared-Q8_0 head, the 114 GiB GTT memory model, client contract, troubleshooting
• frank-large-ciru-orca — RETIRED 2026-09-21 (replaced by frank-large-unsloth-qwen38-flash-next; rollback target): the CIRU v4.4.1 runtime (private host build, QSA hotfix) serving jcbtc/Qwen3.8-Flash-CIRU-STRIX-Orca w4b on the gfx1151 iGPU — one 262,144-token conversation, MTP depth 4, 4096 MiB PLE cache, runtime-root gate, client contract, troubleshooting (2026-09-19 → 09-21)
• halogen-flash-server — RETIRED 2026-09-19 (replaced by frank-large-ciru-orca; rollback target): peonist-ai halogen-flash-server 0.5.8 serving peonist-ai/halogen-qwen3.8-flash-next (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, troubleshooting (2026-09-16 → 09-19)
• frank-small-sglang-mimo-v26 — ACTIVE frank-small runbook since 2026-10-01 (root systemd unit, port 7771): SGLang in a self-contained python3.12 venv serving leteschlead MiMo-V2.6-Distill-Qwen-9B-INT8-W8A16- AutoRound on the RTX 3090 — the same architecture frank-large now serves in BF16 on the iGPU; 2 x 262144 ctx on a pinned 606,208-token fp8 pool, NO spec decode (zero mtp.* tensors shipped), in-checkpoint vision.
• frank-small-gemma4-12b — RETIRED 2026-09-17 → 2026-10-01 (replaced by frank-small-sglang-mimo-v26; rollback target, payload and binary intact on disk): mainline llama.cpp serving HauhauCS/Gemma4-12B-QAT-Uncensored-HauhauCS-Balanced Q4_K_M on the RTX 3090, with the separate MTP assistant sidecar chained behind ngram-mod, q8_0 KV, and --fit sizing the full 262k window into ~12 GiB.
• 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- token pool, 2 concurrent full-context sessions, native text+image+audio.
• frank-small-qwen38-gsq-rco — RETIRED 2026-09-17 (rollback target): the prior frank-small runbook (2026-09-16 → 09-17), ISTA-DASLab Qwen3.8-27B-GSQ-RCO IQ3_S with the model's own in-file MTP head and f16 KV at 131k
• x4-pair-experiment — MEASURED 2026-09-16: what mainline llama.cpp can and cannot do with the 3090 + Strix Halo pair, over their only link (the 3090's Gen4 x4). The tensor inventory that decides any split, the single flag (-ot) that kills per-tensor placement across devices, the two-device layer splits that work (+7 % decode at 64k, cross-vendor included), the harness-parsing trap that invalidated the first round, and the iGPU-only result that matches halogen's deployed decode rate — at a memory cost the co-tenants cannot pay
• frank-large-ik-uncensored — RETIRED 2026-09-16 (rollback target): the ik_llama.cpp runbook (root systemd unit, 2026-09-15 → 09-16) serving mradermacher/Qwen3.8-Flash-Next-Uncensored-i1-Q4_K_M on the RTX 3090 (dense/attention/KV) + LPDDR (experts/PLE) hybrid; its measured envelope and decode root-cause chain are the record of why the fleet went back to halogen
• dankclaw-iommu-translation-off — why Dankclaw boots with amd_iommu=off since 2026-09-11 (13-16 % prefill, measured upstream), what it cost (the NPU endpoint), what was deliberately not copied from the reference machine, and how to revert
• kingjones-strix-rocmfp4 — PRIOR frank-large runbook and rollback target: kingjones777/Qwen3.8-Flash-Next-ROCmFP4-STRIX-GGUF, 177B params (56B MoE + 51.2B PLE), single 113.47 GiB GGUF, on the card's pinned kingjones30/ROCmFPX fork (2026-08-30 → 2026-09-11)
• ubatch-benchmark-large — active-model llama-bench ubatch sweep plan and results
• frank-medium-batch-ubatch — batch/ubatch sweep on the 2x R9700 layer split (2026-09-16): the ubatch optimum at 512, why the logical batch is free, and the split rebalance that followed it
• kingjones-q8agent-rocmfpx — the retired Q8_0-AGENT investigation and set_rows failure
• eemin-rocmi4-mtp — the former caf-eemin Qwen3.8-27B embedded-MTP model on Dankclaw (retired)

• ciru-activefpx-promptforge — the RETIRED v3 CIRU PromptForge runtime on Dankclaw (superseded 2026-08-24 by the kingjones ROCmFP4 model)
• kairic-edge — the retired Kairic Edge IU4 experiment (deployed and reverted 2026-08-22)
• Dankserver System Specs — the 2x R9700 box (frank-primary)
• Dankclaw System Specs — the Strix Halo gfx1151 box (frank-large on the unsloth b11030 runtime since 2026-09-21, frank-small on the RTX 3090)
• frank-npu — RETIRED 2026-09-11: the FLM NPU sight+sound endpoint on Dankclaw (Gemma4 E4B vision+audio pack, XDNA2, port 7771), kept as the retirement record — the IOMMU/SVA err=-19 root cause and where every dependent route moved
