Courses and Workshops CSCS

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

CSCS just published a call for participation to the following course:

Advanced Distributed Memory Parallel Programming: MPI-2.2, MPI-3.0 and PGAS
23-25 May, 2012 at CSCS, Lugano

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 hybridcomputing and Partitioned Global Address Space (PGAS) languages, Coarray Fortran and Unified Paralell 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.

Attendees are encouraged to bring in their own applications and codes for the hands-on sessions. Representatives from MPI 3.0 forum (http://meetings.mpi-forum.org/MPI_3.0_main_page.php) and Cray PE will be present at the meeting for discussions and feedback.  There will be invited talks where presenters share their experiences and discuss issues in using MPI and PGAS on the CSCS systems.

Registration deadline: May 18, 2012.
