### Active Services
|
|
|
|
The active `frank-default-small` service (llama.cpp, `b10108+`) serves the HauhauCS Qwen3.6-35B-A3B uncensored `Q6_K_P` model on port 7770 with a DFlash draft. It runs 3 parallel slots at 200000 context each (pool 600000). All 40 layers' MoE expert weights sit on CPU (`--n-cpu-moe 40`) while non-expert tensors and the full-attention KV cache stay on GPU (`--gpu-layers all`, KV K=`q8_0`, V=`f16`). It uses batch 3072 / ubatch 1536 with `--ctx-checkpoints` and `--no-mmap`. At load it uses about 20 GB of the 24 GB VRAM and about 32 GB of RAM.
|
|
|
|
## Hardware Relevance
|
|
|
|
- 24 GB VRAM limits the GPU-resident footprint. With 3 x 200000 context, the full-attention KV cache plus non-expert weights and the batch 3072/1536 activation buffers consume about 20 GB, leaving about 4 GB of headroom. MoE experts must stay on CPU.
|
|
- 62 GB system RAM holds the ~29 GB of MoE expert weights with room to spare (~57 GB available after load).
|
|
- 127 GB swap is available for CPU KV cache paging if GPU KV offload is disabled.
|
|
- Root disk has approximately 140 GB free. Store the GGUF models under `/home/dank/models` (about 32 GB total).
