Going Parallel (part II: MPI, OpenMP)

Tuesday 28 Nov 2023, 09:30 → 17:30 Europe/Brussels

Shanon (building Maxwell, first floor) (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: Parallel programming with OpenMP 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 move to GPU or use parralelism with shared memory

09:30 → 12:30 Parallel programming with MPI (2)

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)

14:00 → 16:30 Parallel programming with OpenMP

OpenMP is an easy alternative to pthreads for multithread computing. OpenMP extensions now exist in most C and Fortran compilers and allow flagging loops and other construct for efficient multithreading with little supplementary programming effort.
Contents: Parallel programming paradigms OpenMP Execution model Compiling an OpenMP program Data races Parallel loops Barriers and synchronisation	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 programs in C/C++ or Fortran
