NVIDIA NVSHMEM (nvshmem4py) - CUDA 12

NVIDIA NVSHMEM is an implementation of the OpenSHMEM specification for NVIDIA GPUs, providing a Partitioned Global Address Space (PGAS) for efficient and scalable communication in GPU clusters. The `nvidia-nvshmem-cu12` package provides the official Python bindings (NVSHMEM4Py) for CUDA 12.x compatible environments, enabling Python applications to leverage NVSHMEM's high-performance communication model. The current version is 3.6.5, with releases typically occurring several times a year to align with NVSHMEM and CUDA toolkit updates.
