CUDA-Aware-MPI: Part 4: Optimizing strided data communication between GPUs

Hello readers, This is the fourth part from the 4-part CUDA-Aware-MPI series. In this blog series, we will use only NVIDIA GPGPUs and assume that the user know basics about CUDA-Aware-MPI  from the official blogpost : https://developer.nvidia.com/blog/introduction-cuda-aware-mpi/[1]. Also, we assume that the reader knows about solving the 2D Poisson equation. For this, we are going […]
