Pre-registration

Context

Learn to parallelize applications in order to reduce compute time or solve larger problems using MPI/OpenMP programming models.

The course is taught using formal lectures and practical/programming sessions. All examples in the course will be done in Fortran, the exercices can be done in Fortran or C.

Target participants

Engineers, physicists, computer scientists and numerical analysts who wish to learn the fundamental concepts of parallel programming models MPI, OpenMP.

Prerequisites

In order to follow this course, you need to:

• know how to use basic Linux commands,
• master one of these two programming languages : Fortran or C (It is not possible to do the exercises in Java or in Python).

Intended learning outcomes

Learn to parallelize applications in order to reduce compute time or solve larger problems using MPI/OpenMP programming models.

On completion of this course students should be able to :

• parallelise a simple C/FORTRAN program (50 lines) with MPI library and/or OpenMP directives,
• understand and use OpenMP directives ( worksharing , synchronisation) ,
• understand and use MPI functions (point to point communications, collectives, communicators, topologies) .
