I introduced CUDA-aware MPI in my last post, with an introduction to MPI and a description of the functionality and benefits of CUDA-aware MPI. In this post I will demonstrate the performance of MPI through both synthetic and realistic benchmarks. Since you now know why CUDA-aware MPI is more efficient from a theoretical perspective, let��s take a look at the results of MPI bandwidth and��
