cutlass

A fast communication-overlapping library for tensor/expert parallelism on GPUs.

Our first fully AI generated deep learning system

🚀🚀🚀 This repository lists some awesome public CUDA, cuda-python, cuBLAS, cuDNN, CUTLASS, TensorRT, TensorRT-LLM, Triton, TVM, MLIR, PTX and High Performance Computing (HPC) projects.

Examples of CUDA implementations by Cutlass CuTe

CUTLASS and CuTe Examples

Suckless no dependencies CUDA/C++ port of NVIDIA's DVLT, feed it images, get a 3D point cloud + camera poses. NO python. One fast 5MB binary.

Performance of the C++ interface of flash attention and flash attention v2 in large language model (LLM) inference scenarios.

This is my 🔥 100 Days of GPU — a wild, hands-on journey through CUDA/CUTLASS kernels, Triton spells, and PTX sorcery.

GEMM and Winograd based convolutions using CUTLASS

Minimal FlashAttention in CUDA C++/CuTe: readable WMMA/CuTe kernels, no NxN workspace, up to 4.5x faster than naive PyTorch
