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 Fleet

The LLM inference fleet on the two hosts. Full index: serverAppConfigs-docs/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-medium-llamacpp-dflash2 — the ACTIVE frank-medium runbook since 2026-09-16: mainline llama.cpp (gfx1201 HIP build) serving ajgazin/Swift-Qwen3.8-27B-Uncensored-Dynamic-MTP-GGUF at UD-Q8_K_XL with the DFlash2 drafter (z-lab/Qwen3.8-27B-DFlash2-GGUF at Q8_0) on Dankserver's 2x Radeon AI PRO R9700 as one layer-split process behind the :7770 endpoint — no tensor parallelism, because the second card cannot dispatch an RCCL collective
• frank-medium-radiance-mxfp4 — RETIRED 2026-09-16: the vllm-radiance MXFP4 stack serving just1moremodel/Qwen3.8-27B-Uncensored-MXFP4-awq on Dankserver's 2x Radeon AI PRO R9700 as two single-GPU replicas behind a round-robin proxy; kept as the record of the deployment frank-medium-llamacpp-dflash2 replaced, plus the PCIe-atomics evidence that rules out TP=2 on this host (since 2026-09-15/16)
• Dual-R9700-Cooperation — why the two R9700s cannot run tensor-parallel together: the PCIe-atomics gate quoted from ROCclr, the measured RCCL matrix (collectives and P2P send/recv both fail on card #2, which rules out pipeline parallelism too), what is closed and what is still open, and the two hardware paths — a ~$30 M.2→PCIe x4 riser into the free, CPU-attached M.2_2 slot, or a board whose CPU x16 bifurcates to x8/x8
• 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 replaced
• freetoken-benchmark-sweep — KV pool vs decode speed sweep (bs1/bs3/bs4/bs6, 8k–700k KV) on the retired Dankserver RTX 3090
• kingjones-strix-mtp — the Qwen3.8-27B-Q6_0 ROCmFPX AGENT era with the standalone MTP draft (Dankclaw, 2026-08-25 → 2026-08-29; historical)
• agentionai-fast-imatrix — the retired frank-large runbook: agentionai/Qwen3.8-Flash-Next-ROCmFP4-FAST-imatrix (87.06 GiB, Q4_0_ROCMFP4_FAST) + own MTP draft, build-qwen38 (retired 2026-08-30; rollback record)
• halogen-flash-server — the ACTIVE frank-large runbook again since 2026-09-16 (rootless Quadlet, port 7770): 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
• eemin-rocmi4-mtp — the former caf-eemin Qwen3.8-27B ROCmI4 embedded-MTP model on Dankclaw
• ciru-activefpx-promptforge — the RETIRED v3 CIRU PromptForge runtime on Dankclaw (superseded 2026-08-24)
• 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-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 own in-file MTP head + BF16 projector
• ikllama-ornith-dankserver — the retired ik_llama.cpp runtime for the old frank-small (q8_0 + Hadamard KV cache, split-mode none; 2026-08-26)
• freetoken-frank-small — RETIRED 2026-09-15: the FreeToken/CUDA frank-small runbook, retired with the RTX 3090
• kairic-edge — the retired Kairic Edge IU4 experiment (2026-08-22)
• dflash2-large-vulkan — the retired DFlash2 Vulkan deployment (2026-08-21)
• Dankserver System Specs — the 2x R9700 box hardware (frank-medium)
• Dankclaw System Specs — the Strix Halo gfx1151 box (frank-large)
• 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

• 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
