globalToShmemAsyncCopy

globalToShmemAsyncCopy - Global Memory to Shared Memory Async Copy

Description

This sample implements matrix multiplication which uses asynchronous copy of data from global to shared memory when on compute capability 8.0 or higher. Also demonstrates arrive-wait barrier for synchronization.
