Reproducible recipe: serve abliterated Gemma-4-12B (gemma4_unified) at 50-118 tok/s on no-NVLink Blackwell (SM120) via vLLM nightly + ModelOpt FP8/NVFP4 + MTP spec-decode.
Reproducible kit to deploy DeepSeek-V4-Flash-DSpark on a 2× NVIDIA DGX Spark (GB10) cluster: vLLM TP=2 over QSFP 200GbE, NVFP4 KV, DSpark speculative decoding, 1M context, systemd self-heal. Apache-2.0.
Patches + recipe to deploy festr2/MiMo-V2.5-Pro-NVFP4-MXFP8-attn-TP8 on 8-node DGX Spark sm_121 (Ray + vLLM, TP=8). Fixes the fused-qkv loader bug that mis-slotted Q values as K/V on 7 of 8 ranks.
Field-tested guide: multi-GPU vLLM tensor-parallel (TP=2/TP=4) on Intel Arc Pro B70 (Battlemage BMG-G31, Xe2) on Linux. Driver setup (xe force_probe=e223), bare-metal vLLM + oneAPI 2025.3, the compute-runtime multi-root USM + triton-xpu init_devices fixes, FP8/int4-AutoRound quant, root-cause error reports. AI-agent readable (AGENTS.md).
A ~800-line PyTorch implementation of Megatron-LM's TP + PP + DP + AMP. 1.6-2x faster than Megatron-Core on 125M models.
Deploy DeepSeek-V4-Flash-0731 on dual NVIDIA RTX PRO 6000 Blackwell GPUs with vLLM PR #41834 (jasl fork) and DSpark speculative decoding, achieving ~200-227 tok/s in no-overseas-network environments.
Serve an abliterated Gemma-4-12B at high speeds on Blackwell GPUs without NVLink using vLLM, FP8 quantization, and MTP speculative decoding.
From-scratch C++/SYCL LLM inference engine for Intel Arc (B-series) — 8+ architectures, tensor-parallel, beats llama.cpp on Arc B70
Measured LLM benchmarks for NVIDIA DGX Spark (GB10): DeepSeek-V4-Flash 284B MoE on a TP=2 pair over 200G RoCE — tok/s by profile and concurrency, 1M-token context curve, the MoE backend flag, monitoring traps. Every number links to raw runs.
Reproducible llama.cpp kernel and runtime optimization lab for dual NVIDIA Tesla V100 GPUs (SM70)
Run large LLMs across two NVIDIA DGX Sparks with vLLM — model picker, one-command start/switch, and an Anthropic-compatible endpoint for Claude Code.
Two-node DGX Spark operator tooling and measurement harness for DeepSeek-V4-Flash
Deployment kit: Thinking Machines Inkling-Small-NVFP4 (276B MoE) on 2x NVIDIA DGX Spark — TP=2 over QSFP, vLLM 0.26, FA4 SM120 kernel fixes, full docs + bench harness. C1 21.4 / C8 93.9 tok/s measured.
Lightweight terminal launcher and auto-optimizer for llm models using llama.cpp with hardware detection, tensor sharding, benchmarks, presets, context tuning, and OpenAI-compatible serving.
