NVIDIA CUTLASS Python DSL

NVIDIA CUTLASS Python DSL (version 4.4.2) is a Python-based domain-specific language (DSL) for writing high-performance CUDA kernels. It provides a Pythonic interface to CUTLASS's CuTe library, enabling kernel development with automatic JIT compilation to optimized PTX/SASS for NVIDIA GPUs (Ampere, Hopper, Blackwell architectures). It aims for zero-cost abstraction, performance comparable to C++ kernels, and seamless integration with deep learning frameworks like PyTorch and JAX. The library maintains an active development pace with frequent updates and minor version releases.
