Hand-written NVFP4 W4A16 CUDA kernels for Volta
Agentic-coding oriented inference engine for N x V100-SXM2, based on SGLang: GLM-5.3-Flash, Qwen3.8-Flash-Next, DeepSeek-V4.1-Flash, MiniMax-H3.
Benchmarks and notes for running modern LLMs with vLLM on 8x Tesla V100-32GB in 2026.
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.
Reproducible llama.cpp kernel and runtime optimization lab for dual NVIDIA Tesla V100 GPUs (SM70)
Runbook + benchmarks: Qwen3.8-Flash-Next-ABLITERATED NVFP4 on 4× Tesla V100-32GB (reflashed SXM2→PCIe, 2+2 NVLink + PLX). 1Cat-vLLM 1.5.0, TP4 — 262,144-token context validated, 46 tok/s decode, 122 tok/s aggregate at 4 concurrent streams. Full E0–E17 optimization log with measured evidence.
双 V100 (SXM2/NVLink) 运行 Strata 引擎:Flash-Next 125B MoE SM70 实验通道编译移植、peer-tier 双卡部署实录与深度基准(解码 59~63 tok/s / Prefill 765 tok/s)
SGLang fork for IBM POWER9 (ppc64le): Tesla V100 sm70, CUDA 12.4, Granite LLM inference. Triton attention, float16, OpenAI-compatible API.
DP4A FlashAttention-2 and GEMM for Volta GPUs. 46 TOP/s INT8 on CMP 100-210 where tensor cores are firmware-disabled. The .superl8 format loads weights at memory speed.
V100 (sm_70) tuning kit for Ternary Bonsai 2 27B: q8_0-KV flash-attention direct read, D256 Split-D prefill kernel, PTQ1_0 planar mat-vec, MTP graft + draft micro-batch fix, ubatch presets. Prefill 175 -> 854 t/s, VRAM -1.9 GiB, PPL bit-identical (2-chunk). 中英双语 README (README.md / README.zh-CN.md).
Measured llama.cpp and quantization results on Tesla V100 (sm_70), Pascal GTX 1070, and RTX 4070 - hardware most projects don't test on
Run SeedVR2 video upscalers on Tesla V100 (Volta) — fixes the silent black-video fp16 bug with an FP16Safe-style patch.
[Unmaintained, use dg1kjd/sglang-sxm2] Qwen3.5-397B-A17B (AWQ) on 8x Tesla V100-SXM2-32GB with vLLM, a downstream fork of 1Cat-vLLM.
PyTorch 2.12 fork for IBM POWER9/POWER10 (ppc64le) with CUDA 12.4 and Triton. Tesla V100 sm70, GPU training and LLM inference.
