NVIDIA cuSPARSELt

NVIDIA cuSPARSELt is a Python binding to the NVIDIA cuSPARSELt library, providing highly optimized routines for sparse matrix-matrix multiplication (SpMM) on NVIDIA GPUs. This specific package, `nvidia-cusparselt-cu13`, targets CUDA Toolkit 13.x. It's a low-level library typically used for high-performance computing and deep learning workloads involving sparse data structures. Its release cadence is generally tied to major CUDA Toolkit updates.
