CuPy: A NumPy-compatible Library for GPU
summary
CuPy claims a NumPy-compatible array API that runs on NVIDIA GPUs via CUDA and uses cuBLAS cuDNN cuSPARSE cuSOLVER cuRAND and NCCL to speed linear algebra and deep‑learning ops. It shows ~6× speedups on large matrix ops, supports custom CUDA kernels, uses a memory pool to cut cudaMalloc overhead (up to ~55% memory savings), offers prebuilt wheels so users can pip install cupy, and provides experimental fusion and cross‑platform work toward Windows and ROCm.
