NVIDIA® NVSHMEM 3.3.24 Release Notes#

NVSHMEM is an implementation of the OpenSHMEM specification for NVIDIA GPUs. The NVSHMEM programming interface implements a Partitioned Global Address Space (PGAS) model across a cluster of NVIDIA GPUs. NVSHMEM provides an easy-to-use interface to allocate memory that is symmetrically distributed across the GPUs. In addition to a CPU-side interface, NVSHMEM provides a NVIDIA® CUDA® kernel-side interface that allows CUDA threads to access any location in the symmetrically-distributed memory.

The release notes describe the key features, software enhancements and improvements, and known issues for NVSHMEM 3.3.20 and earlier releases.
