# Dankclaw System Specs

## Server Overview

Dankclaw is an AMD APU + RTX 3090 inference host. It ran CIRU ROCmFPX llama.cpp inference through 2026-08-22 ([[frank-dragoon]], retired). 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. Today it serves [[frank-dragoon]] (halogen-flash-server 0.16.2 on the iGPU, port 7770) and [[frank-zealot]] (llama.cpp PrismML fork on the RTX 3090, port 7771).
## Hardware Specifications

### CPU

| Property | Value |
|----------|-------|
| Model | AMD RYZEN AI MAX+ 395 w/ Radeon 8060S |
| Architecture | x86_64 |
| Cores | 16 (1 socket, 1 thread per core) |
| Max MHz | 5187.50 |
| Min MHz | 625.00 |
| NUMA Nodes | 1 (node 0, 124129 MB — `Node 0 MemTotal: 127108080 kB`, read 2026-10-18) |

### GPU (Integrated)

| Property | Value |
|----------|-------|
| Model | AMD Radeon 8060S (Strix Halo) |
| Device ID | 0x1586 |
| Architecture | gfx1151 (Strix Halo) |
| GPU-Visible Memory | ~114 GiB GTT aperture (the budget; `mem_info_gtt_total` = 122,402,963,456 B read 2026-10-18; rocm-smi's smaller SVM carve-out is not the budget) |
| Physical RAM | 121 GiB visible to the OS (`free -g` total 121, read 2026-10-18) on a 128 GB part — 8 × 16 GB LPDDR5 ( §hardware). The 64 GiB this page recorded as "corrected 2026-08-17" (from 32 GB) is stale |

### NPU

| Property | Value |
|----------|-------|
| Model | AMD XDNA2 (Ryzen AI) |
| Rating | 50 TOPS |
| Device | /dev/accel/accel0 |
| Driver | amdxdna 0.7.0, in-tree — bound since 2026-10-18 (`lspci -k -s c6:00.1` → `Kernel driver in use: amdxdna`; journal 2026-10-18 01:25:14 `Initialized amdxdna_accel_driver 0.7.0 for 0000:c6:00.1 on minor 0`) |
| Firmware | 1.1.2.65 (`/usr/lib/firmware/amdnpu/17f0_11/npu_7.sbin` → `npu.sbin.1.1.2.65.zst`, loaded at boot 2026-10-18 01:25:13) |
| Runtime | Distro XRT only: `libxrt2` + `libxrt-npu2` 1:2.21.75 supply `libxrt_coreutil.so.2`, `libxrt_core.so.2` and the NPU plugin `libxrt_driver_xdna.so.2` under `/usr/lib/x86_64-linux-gnu`; **no `/opt/xilinx/xrt`** (census 2026-10-19), no Ryzen AI Python stack. FastFlowLM 0.9.45 + AMD's XRT (installed 2026-08-16) was **retired 2026-09-11** with the `amd_iommu=off` decision — see [[dankclaw-iommu-translation-off]]; the package remains at `/home/dank/GitPackages/fastflowlm_0.9.45_ubuntu26.04_amd64.deb` |
| Status | Not in service — no NPU consumer is deployed. The device itself is usable since the 2026-10-18 `iommu=pt` boot (`/dev/accel/accel0` present, `crw-rw---- root:render 261,0`); Gitea issue #3 tracks enablement. The only runtime here that ships precompiled programs this device can execute is halogen's — see [[frank-dragoon]] §The NPU lane |

This section is device inventory, not a payload record. The name `frank-zealot` served the FLM NPU endpoint until
2026-09-11 and has served Bonsai-2 on the RTX 3090 through the llama.cpp PrismML fork since; the checkpoint, the
shape and every era are on [[frank-zealot]], and any figure restated here is the next thing to go stale.

### ROCm

| Property | Value |
|----------|-------|
| ROCk Module | Loaded |
| Runtime Version | 1.18 |
| ROCm Version | 7.2.4 system (`/opt/rocm/.info/version` = 7.2.4, read 2026-10-18). The TheRock 7.15 SDK that lived in the CIRU venv left the serving path when CIRU was retired 2026-08-22 |
| Agent Name | AMD RYZEN AI MAX+ 395 w/ Radeon 8060S |
| GPU Arch | gfx1151 (Strix Halo) |
| GPU Global Memory | ~114 GiB GTT aperture (the budget) |

### Memory

| Property | Value |
|----------|-------|
| System RAM | 121 GiB (shared CPU + GPU; `free -g` total 121, `MemTotal 127108080 kB`, 2026-10-18) |
| GPU-Visible (ROCm) | ~114 GiB GTT aperture (`mem_info_gtt_total` 122,402,963,456 B — the budget) |
| Swap | 64 GB `/swap.img` (`swapon`, 2026-10-18; `free` reports 63 GiB) |
| TTM page cap | `ttm.pages_limit = 29883536` (114 GiB of 4 KiB pages) and `page_pool_size=29883536`, persisted in `/etc/modprobe.d/ttm.conf`, applied live 2026-08-25 and re-read 2026-10-18 (`/sys/module/ttm/parameters/pages_limit`). The kernel default is half of RAM, so in the firmware-VGM era (~30 GiB visible) the cap was ~15 GiB and a 28 GB payload plus a 262k KV cache could not load — this is the row every other page should cite |
| /dev/shm | 61 GiB tmpfs (half of RAM, `df /dev/shm`, 2026-10-18) |

### Storage

| Filesystem | Size | Used | Avail | Use% |
|------------|------|------|-------|------|
| / (nvme0n1p2) | 1.9T | 1.4T | 424G | 77% |

### Network

| Interface | Type | Speed | IP | Notes |
|-----------|------|-------|----|-------|
| eno1 | onboard | 2500 Mb/s (2.5 GbE) | 192.168.0.143 (DHCP) | Carried the RPC path to Dankserver during the 2026-08-17 pipeline-parallelism trial; no RPC listener runs today (`ss -ltn` shows no :50052, 2026-10-18). Default route via 192.168.0.1. |
| enx00e04cc2e1e5 | USB-C to Ethernet adapter | 1000 Mb/s | 192.168.0.116 | UNPLUGGED 2026-08-17. While present, the route to 192.168.0.235 went through this adapter (lower route metric), so all RPC traffic was capped at 1 GbE. See  section 0. |
| docker0 | bridge | - | 172.17.0.1 | Usually down. |

The L2 gateway/switch at 192.168.0.1 (MAC f0:4b:8a:65:c5:40) is at
least 2.5 GbE-capable. Whether it is 10G-capable is unverified — check
the device itself before buying 10G USB-C adapters; otherwise a direct
cable between claw and server is required for 10G.

### OS and Software

| Property | Value |
|----------|-------|
| OS | Ubuntu 26.04 LTS (Resolute Raccoon) |
| Kernel | 7.0.0-38-generic (`uname -r`, 2026-10-18) |
| Boot line | `iommu=pt` since 2026-10-18 (`/proc/cmdline`, no `amd_iommu` token); eras before: `amd_iommu=off` 2026-09-11 → 10-18, IOMMU default-on before that — [[dankclaw-iommu-translation-off]] |
| Python | 3.14.4 (system, `python3 --version`, 2026-10-18). The 3.12.13 CIRU venv left with that runtime (retired 2026-08-22) |
| CIRU runtime | ciru-ai/ROCmFPX — **retired 2026-08-22** ([[frank-dragoon]]); not the serving runtime |
| uv | 0.12.8 (`~/.local/bin/uv --version`, 2026-10-18) |

## Runtime Relevance

- Unified memory eliminates separate VRAM limits. The GPU uses system RAM.
- The GPU budget is the GTT aperture: ~114 GiB (`mem_info_gtt_total` in `/sys/class/drm/card1/device/` = 122,402,963,456 B; `card1` is the amdgpu iGPU, `PCI_ID=1002:1586`; `llama-server --list-devices` reports 116,732 MiB). rocm-smi's smaller SVM/dedicated carve-out is **not** the budget — the 2026-08 "64 GiB rocm-smi" lesson is stale. Do not use `free` or `dmidecode` for the GPU budget.
- The active services are `frank-dragoon` on 7770 — **halogen-flash-server 0.16.2** serving the native v2 abliterated `.hgn` in a rootless podman container ([[frank-dragoon]]) — and `frank-zealot` on 7771 ([[frank-zealot]]). The gufo v0.1.1 / UD-Q8_K_XL runtime this page once described is retired (2026-09-28 → 10-01, [[frank-dragoon]]); the gufo build tree is still on disk at `/home/dank/GitPackages/gufo-v0.1.1/`.
- The gufo-era note that the active runtime links against the host ROCm (`/opt/rocm` → `/etc/alternatives/rocm` → 7.2.4) through its RPATH belongs to that retired source build. The serving runtimes do not depend on the host ROCm that way: halogen runs inside its digest-pinned image, and `frank-zealot` is a CUDA build on the 3090. The retired CIRU venv's TheRock 7.15 SDK (`LD_LIBRARY_PATH`) was never in the serving path either.
- The retired vLLM venvs (`/home/dank/vllm-venv`, `/home/dank/vllm-vk-venv`) were moved to `/home/dank/.AGENTTRASH/` on 2026-08-18.
- 424 GB free on `/` (`df -h`, 2026-10-18) is ample for model storage.
