Update target maps (AGENTS, README, deployment, deploy.sh) from the retired ROCmFPX llama.cpp stack to the active vLLM-ROCm CIRU INT4 service on port 7770 with MTP speculative decoding. Align Dankserver to the running vllm-awq-qwen36 (AWQ, port 34401). Refresh KB pages: Dankclaw system specs (gpu-mem-util 0.95, CIRU venv), quantization choices (INT4 primary, MXFP4 experiment), DFlash/DSpark Dankclaw section, and the KB index topology.

# Dankclaw System Specs
|
|
|
|
## Server Overview
|
|
|
|
Dankclaw is an AMD APU server for vLLM inference. The host runs Ubuntu 26.04 with an AMD Ryzen AI MAX+ 395 Strix Halo APU. The APU uses unified memory — CPU and GPU share the same physical RAM pool.

## VLLM Relevance
|
|
|
|
- Unified memory eliminates separate VRAM limits. The GPU uses system RAM.
|
|
- ROCm reports 96 GiB of GPU-visible memory (overcommitted). The current vLLM service runs at `--gpu-memory-utilization 0.95`, which fits the CIRU INT4 weights and 256k KV cache (about 90 GiB used of the 96 GiB frame buffer).
|
|
- Without the ROCm VRAM patch, ROCm clamps APU memory to 50% (see `scripts/patches/rocm_patched.py` on the remote). The patch restores the real GTT ceiling minus an 8 GB safety margin.
|
|
- Only 8 GiB swap. Modern vLLM uses `--kv-offloading-size` instead of the removed `--swap-space` flag.
|
|
- The active service on Dankclaw is `frank-default-large.service`: vLLM-ROCm serving the Ling-3.0-flash CIRU INT4 (W4A16) model on port 7770 with native MTP speculative decoding. It replaced the ROCmFPX llama.cpp service.
|
|
- ROCm 7.2.4 from AMD repos. The CIRU venv bundles a self-contained ROCm 7.15 toolchain; vLLM ROCm support requires ROCm 6.3+.
|
|
- Python 3.14.4 is very new. vLLM ROCm wheels target Python 3.12. The CIRU venv uses Python 3.12.
|
|
- Radeon 8060S falls under Ryzen AI MAX series (gfx1151). vLLM lists this as supported.
|
|
- 1.1 TB free disk space is ample for model storage.
|
|
- `libmpi_cxx.so.40` is missing from the system. Install `openmpi-bin` or provide a workaround for torch MPI dependency.
