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.

Target participants

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


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.

Trophy of the Digital Simulation and Artificial intelligence 2020 – Co design category

Jérôme DOMBARD |  27 October 2020

The "Usine Digitale" magazine and Teratec awarded the Digital Simulation and Artificial intelligence Trophy 2020 category co-design to our joint project about the first LES of a full engine with Akira Tech and Safran. More information on Acknowledgments: these results are part of the ATOM project led by SafranTech which received funding from the DGAC, French Civil Aviation Authority, and Safran under grant agreement No 2018-39.Read more

Young PhD day (JDD) – Thursday 8 October 2020

Brigitte Yzel |  24 September 2020

  Ph.D. Students' Day (JDD 2020) Thursday 8 October 2020 Virtual event open to our partners and associates   Planning   The 2020 edition of the PhD Students' Day will take place on October 8th, 2020. This year, this day of the PhD students of the Cerfacs, will take place mainly in visio in order to respect all the health safety measures relating to Covid-19. This day will be held in a virtual way through oral presentations filmed and broadcast on a private link, which we will distribute to all participants. Everyone will thus be able to discover at a distance the subjects developed by the doctoral students. At the same time, the "Posters session" will be opened on the morning of the JDD, by sending all the posters in pdf format by e-mail to all the participants for consultation, and by opening the "50-minute question session" on a channel whose links we will send you. This will allow participants to ask questions about the posters of the session. Finally, we have included in this 5th edition a great novelty, by allowing several students to present their subject in the popularised form of "My thesis in 3 minutes", guided by Matthieu Pouget, actor and theatre director. This day will end with the vote for the "Best poster" and the "Best presentation of My thesis in 3 minutes". Participation in the event is free of charge. However, for logistical reasons, registration, only by invitation, is mandatory.   Organising Committee:  Scientific committee  Nicolas Venkovic Victor Xing Inscription &  information Jade Schweiger Brigitte Yzel  Read more
