LLM Fleet — Knowledge Base

Documentation for the LLM inference fleet on the two hosts (2026-09-20): vllm-radiance on Dankserver serving frank-medium as ONE tensor-parallel process across both Radeon AI PRO R9700 cards (just1moremodel Qwen3.8-27B-Uncensored MXFP4-awq + the z-lab DFlash2-FP8 drafter, TP=2 over the R4D one-shot allreduce), and TWO endpoints on Dankclaw — the CIRU v4.4.1 runtime (frank-large, jcbtc Qwen3.8-Flash-CIRU-STRIX-Orca w4b on the gfx1151 iGPU, port 7770) and mainline llama.cpp (frank-small, HauhauCS Gemma4-12B QAT Q4_K_M with MTP and vision on the RTX 3090, 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-medium-radiance-mxfp4 — the ACTIVE frank-medium runbook since 2026-09-20: vllm-radiance MXFP4 (stilldeadcode/vllm-radiance:0.9.3 + ggz14/radiance-vllm-mxfp4 patches) serving just1moremodel/Qwen3.8-27B-Uncensored-MXFP4-awq with the z-lab DFlash2-FP8 drafter as ONE tensor-parallel process (TP=2) behind :7770 — the three-arm battery that chose it, the auto-sized 943,581-token KV pool, verified capabilities (tools, reasoning, vision), and the record of the 2026-09-16 two-replica era
• 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at Q8_0 with the DFlash2 Q4_K_M drafter as ONE layer-split process (32:33 over two 163,840-token slots); superseded by the radiance TP=2 cutover, and the rollback target.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-ciru-orca — ACTIVE frank-large runbook since 2026-09-19 (root systemd unit, port 7770): 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
• 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-gemma4-12b — ACTIVE frank-small runbook since 2026-09-17 (root systemd unit, port 7771): 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. A same-day vLLM detour (2026-09-19) was reverted the same day; see below.
• 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)
• dealign-ornith-crack — the retired Ornith-1.5-35B-A3B CRACK model on Dankserver (frank-small, retired 2026-09-02)
• ikllama-ornith-dankserver — the retired ik_llama.cpp runtime for frank-small (2026-08-26): q8_0 + Hadamard KV cache, split-mode none (single-GPU), mandatory FA_ALL_QUANTS build flags
• kingjones-strix-mtp — the former Q6 AGENT runbook (restored 2026-09-01 after Q8_0 failure, then superseded by the STRIX deployment on 2026-08-27)
• 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-medium)
• Dankclaw System Specs — the Strix Halo gfx1151 box (frank-large on the CIRU v4.4.1 runtime since 2026-09-19, 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
