Abstract
This course aims at learning 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.
Objective of the training
To learn the fundamental concepts of parallel programming models MPI, OpenMP
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).
Teaching methods
The training is an alternation of theoretical presentations and practical work. A multiple choice question allows the final evaluation. The training room is equipped with computers, the work can be done in sub-groups of two people.
Referent Teacher: Iabelle d’Ast
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),
- the training can take place in French or English depending on the audience, level B2 of CEFR is required.
In order to verify that the prerequisites are satisfied, one the following questionnaire must be completed (Fortran or C). You need to get at least 75% of correct answers in order to be authorized to follow this training session. If you don’t succeed it, your subscription will not be validated. You only have two chances to complete it.
