- 2x NVIDIA DGX Spark (GB10) cluster, TP=2 over RoCE. FP8 KV cache + MXFP4 MoE, MTP=2, 200K ctx (aidendle94/sparkrun-vllm-ds4-gb10). Warm single-stream, temp=0. ttftMs=median of 3 (short prompt, streaming). tokSOut=median of 3 (code prompt, max_tokens=256, completion_tokens/decode_seconds). tokSPrefill=median of 3 (~2000-token unique prompts, prefix-cache defeated). Unified memory 128GB/node (242GB combined pool); peakVramGb=209 = 105GB(node1)+104GB(node2) actually used.
