Advanced Distributed Memory Parallel Programming: MPI-2.2, MPI 3.0 and PGAS Tutorial at CSCS

Advanced Distributed Memory Parallel Programming: MPI-2.2, MPI 3.0 and PGAS

Host

Overview

The goal of this training workshop is to introduce MPI-2.2 performance critical topics and to provide an overview of MPI 3.0, MPI for hybrid computing and Partitioned Global Address Space (PGAS) languages, Coarray Fortran and Unified Parallell C (UPC). For lab sessions, Cray XK6, a massively parallel processing (MPP) platform with GPUs and a QDR InfiniBand cluster with Intel processors and GPUs will be targeted.

The advanced MPI part (first two days with hands-on sessions) is presented by Torsten Hoefler (UIUC/ETH) and the PGAS part (last day with hands-on sessions) is presented by Roberto Ansaloni (Cray). This page focusses on the MPI part.
