ThunderKittens Releases 2.0 CUDA DSL and Kernels
|
8.2
ThunderKittens, an open-source CUDA-embedded DSL, announces version 2.0, introducing MXFP8/NVFP4 support, CLC scheduling, tensor memory controllability, PDL, multi-GPU features, a major internal refactor, and a simplified build system. The project reports BF16/MXFP8/NVFP4 GEMM kernels that match or exceed cuBLAS on Nvidia B200s and provides a technical deep dive on memory consistency, tensor-core pipelining, PTX hinting, occupancy, and benchmarking.
