The radiance MXFP4 stack cannot run TP=2 on this host. RCCL's collective
kernels carry a hidden hostcall-buffer parameter, and ROCr refuses to
dispatch them on a device without PCIe atomics: the AQL dispatch fails with
hipErrorIllegalState ("the operation cannot be performed in the present
state"), which is what every two-rank collective hit. The second R9700 sits
behind the chipset bridges 05:00.0/06:09.0, which advertise
`AtomicOpsCap: Routing-` — a read-only capability, so no software can enable
atomic routing on that path and the driver's
pci_enable_atomic_ops_to_root() fails for that card. The first card, on CPU
root port 00:01.1, has atomics enabled.
Ruled out: kernel version (7.0.0-28/-30/-31 identical, after a full upgrade),
iommu=pt, P2P hardware (45.3 GB/s between the cards), the shipped librccl (a
from-source rebuild reproduces the failure at the same call path), vLLM and
pynccl (a bare two-rank torch.distributed allreduce fails the same way), all
NCCL transport knobs, and single-rank tests (NCCL short-circuits at
world_size=1, so one-card success proves nothing).
Deployment: three rootless Quadlets — frank-medium-a (:7771, card 1),
frank-medium-b (:7772, card 2), both TP=1 at 114688 context (262144 and
131072 do not fit one card's KV) with vLLM-profiled KV — and
frank-medium-proxy (:7770), a round-robin that preserves the fleet contract
of one endpoint and one served model name. frank-medium.container stays as
the TP=2 target for a host whose second card is atomic-capable; the deploy
handler does not install it and trashes any stale copy.
Measured through the proxy (vllm bench serve, random dataset, --ignore-eos):
conc 1 42.8 tok/s, conc 4 147.6 tok/s, conc 8 230.8 tok/s, 32k prefill at
~2.8k tok/s per card, TPOT p50 23.6-28.8 ms.
Also: healthcheck reads PORT so one probe serves all three units, the hermes
example and the harness models.yml drop to the real 114688 context, and the
runbook records the full evidence chain.

# 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).

Uncensored-i1-Q4_K_M on the RTX 3090 + Strix Halo hybrid (root systemd
|
||
unit, port 7770) — measured performance envelope and traps
|
||
- [[halogen-flash-server]] — the RETIRED 2026-09-15 halogen runbook and

||
- [[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
