Hand-written NVFP4 W4A16 CUDA kernels for Volta
The set-and-forget LLM engine for Pascal and Volta: PXQ codec + kernels, auto-tuned per card. Ready-to-run PXQ models in MODELS.md; benchmarks vs llama.cpp in the README.
Benchmarks and notes for running modern LLMs with vLLM on 8x Tesla V100-32GB in 2026.
Run Qwen3.6-27B on four Tesla V100s at 366 tok/s using hand-written NVFP4 CUDA kernels and chain-MTP speculation.
FlashAttention brought back to Tesla V100 — a deep llama.cpp fork: SM 7.0 D256 kernels, SplitKV3, q4_0 KV cache, DFlash2 speculative decoding and multimodal fixes.
Qwen3.8-27B in native NVFP4/FP8 on 2x PCIe Tesla V100-32GB (SM70): the PCIe runbook for v100-skinny + 1Cat-vLLM, with the 3 fixes that make it work without NVLink. 61-74 tok/s decode, MTP speculative decoding, OpenAI-compatible.
Zsh plugin to seamlessly install and configure volta
📦 A fully automated method for installing Nvidia drivers on Arch Linux
Qwen3.8-Flash-Next (125B MoE, NVFP4) on 4x V100-SXM2-32GB and DeepSeek-V4.1-flash on 8x V100 — a Volta port of SGLang for agentic coding.
Running large LLMs on pre-Ampere NVIDIA hardware — Tesla V100 (sm_70), RTX 2080 Ti (sm_75), CMP 170HX. Measured benchmarks, vLLM forks, and the hardware side: NVLink on SXM2 carrier boards, driver traps, cooling, used-kit acceptance.
Multi-GPU acceleration for MiniMax H3 video generation on NVIDIA V100 (sm_70). Ulysses sequence parallelism as a drop-in ComfyUI custom node — ~19 min to ~7 min on 8x V100.
Run DLSS 5 Neural Rendering in ComfyUI on pre-RTX GPUs (Tesla V100 / Volta and other non-RTX NVIDIA cards) — no NGX required
