Going Parallel (Part I: General methods and tools, MPI)

Wednesday 26 Nov 2025, 09:30 → 16:30 Europe/Brussels

CYCL09B (Louvain-La-Neuve)

Going parallel is crucial to speed up your gain and to use the full power of HPC center. In this session, we will finish the MPI presentation and continue by presenting the share memory model (OpenMP).
Contents: General idea Parallel programming and tricks  OpenMPI	Prerequisite: Being able to use SSH with private keys  Being familiar with a text editor  Mastering the Linux command line and the GNU utilities (mkdir, cp, scp, etc.) Passive knowledge of C
	Type: Hands-on Target audience: Rookie programmer Must: This session is a must-have for anyone that want to run computing intensive task on HPC clusters.

09:30 → 12:30 Introduction to parallel computing

Speaker: Damien François (UCLouvain/CISM)

13:30 → 16:30 Parallel programming with MPI

MPI is a standard for passing messages between processes running on distinct computers. It offers high-level primitives for efficient communication.
Contents: Parallel programming paradigms Shared-memory vs message passing Compiling an MPI program Collective communication Reduction operations Communication modes	Prerequisite: Being able to use SSH with private keys  Being familiar with a text editor  Mastering the Linux command line and the GNU utilities (mkdir, cp, scp, etc.) Passive knowledge of C or Fortran
Type: Hands-on Target audience: Rookie programmer Must: This session is a must-have for anyone writing or even simply using MPI programs

Speaker: Mr Orian Louant (Université de Liège)
