Rootless Quadlet on dankserver serving just1moremodel/Qwen3.8-27B-Uncensored-MXFP4-awq (the radiance stack's designated alternate target; ships its fp8 MTP head, no rewrite step) with the DFlash2-FP8 drafter at SPEC=7 on the 2x R9700s (TP=2, host network, :7770, alias frank-medium unchanged). - dankserver/frank-medium/: quadlet unit, container entrypoint (fork of serve-mxfp4.sh's patch block at pinned clone commit 97353293), healthcheck - dispatcher retires the root llama.cpp unit, re-tags the registry image to the localhost alias, installs the quadlet, waits on /health - planner maps dankserver/frank-medium/* to frank-medium; scripts-era mappings removed - ROCmFPX-era env/serve/unit/download scripts staged in scripts/.AGENTTRASH with .rocmfpx suffix; seams updated (frank_medium_quadlet.bats new)

# The dankserver LLM endpoint (:7770, alias frank-medium), since 2026-09-15
|
|
# running the vllm-radiance MXFP4 stack (stilldeadcode/vllm-radiance:0.9.3
|
|
# image + the ggz14/radiance-vllm-mxfp4 patches) serving
|
|
# just1moremodel/Qwen3.8-27B-Uncensored-MXFP4-awq on the 2x Radeon AI PRO
|
|
# R9700 (gfx1201) cards. It replaced the charlie12345/ROCmFPX llama.cpp
|
|
# deployment, which served the same alias from the Q8_0_ROCMFPX_AGENT GGUF;
|
|
# the MXFP4 stack is tensor-parallel (TP=2, R4D one-shot all-reduce) with the
|
|
# DFlash2-FP8 block-diffusion drafter (SPEC=7) — the measured production
|
|
# configuration of the upstream repo, on our exact hardware signature
|
|
# (2x7551-32624, see the KV pin below).
|
|
#
|
|
# SHAPE. The launcher the upstream repo ships binds the server with
|
|
# --network=host (vLLM takes --host 0.0.0.0 --port 7770 directly), which is
|
|
# what this unit does too — no PublishPort. The fleet contract is unchanged:
|
|
# :7770, served model name frank-medium (SERVED_NAMES), OpenAI /v1.
|
|
#
|
|
# DEVICES. /dev/kfd + /dev/dri through the amdgpu/KFD stack; HIP/ROCR device
|
|
# indices 0,1 (the two R9700s). The 2 GiB Raphael iGPU enumerates as index 2
|
|
# and is excluded both by the index pin and by the upstream MIN_GPU_MIB=8192
|
|
# logic this unit replaces. --privileged --ipc=host --security-opt
|
|
# seccomp=unconfined --cap-add SYS_PTRACE is the upstream launcher's exact
|
|
# podman posture.
|
|
#
|
|
# MOUNTS. /models (rw checkpoints), the HF cache (tokenizer files),
|
|
# /cache (Triton/inductor/aiter/vLLM compile cache — first start compiles for
|
|
# several minutes, later starts reuse), /patches (the pinned radiance clone —
|
|
# its patches are applied at EVERY container start by the entrypoint), /r4d
|
|
# (the patched libr4d build; the image's shipped r4d.so NaNs the
|
|
# gated-delta-net and must never be used), and the entrypoint + healthcheck
|
|
# scripts from this checkout (mounted read-only straight out of
|
|
# /home/dank/serverAppConfigs — deploy.sh git-pulls the checkout before
|
|
# dispatching).
|
|
#
|
|
# IMAGE. The unit runs the localhost/-aliased tag: this host's podman quadlet
|
|
# path cannot resolve registry-prefixed refs from local storage at create
|
|
# time (same as frank-large on dankclaw). deploy-remote.sh pulls the
|
|
# docker.io ref and re-tags it before the restart. Pull=never keeps boots off
|
|
# the registry.
|
|
#
|
|
# KEEP IN SYNC: the radiance clone is pinned (97353293...); if it is updated,
|
|
# re-diff dankserver/frank-medium/radiance-entrypoint.sh against the new
|
|
# serve-mxfp4.sh container command and bump the pin deliberately.
|
|
#
|
|
# DO NOT name an environment variable TEMP, HOST or GPU_MAX_HEAP_SIZE: the
|
|
# HIP runtime reads bare TEMP for its JIT cache path (2026-08-13 incident).
