S7133 - Multi-GPU Programming with MPI

Session Speakers
Session Description

Learn how to program multi-GPU systems or GPU clusters using the message passing interface (MPI) and OpenACC or NVIDIA CUDA. We'll start with a quick introduction to MPI and how it can be combined with OpenACC or CUDA. Then we'll cover advanced topics like CUDA-aware MPI and how to overlap communication with computation to hide communication times. We'll also cover the latest improvements with CUDA-aware MPI, interaction with Unified Memory, the multi-process service (MPS, aka Hyper-Q for MPI), and MPI support in NVIDIA performance analysis tools.
