In April 2021, 95% of participants in this training were very satisfied or satisfied

(results collected from 19 respondents out of 30 participants, a response rate of 63%)

Abstract

GIT is a distributed revision control and source code management system. It was initially designed for Linux kernel development and is particularly adapted to multi-site and multi-developer environments. In the morning, the basic knowledge of source code management are taught, presenting most GIT functionalities with many illustrations. A brief comparison with other management tools (Mercurial,CVS,SVN) is also proposed. In the afternoon, a hands-­on session with detailed exercices is organized to illustrate the main concepts.

Objective of the training

The objectives of this course are to help the participants learn how to use GIT in order to manage the development of a multi-site and multi-developer code.

Learning outcomes

On completion of this course, you will be able to :

  • to use the essentials of GIT for all your source code developments;
  • choose the best strategy concerning the creation of different branches;
  • solve the conflicts during the “commit phases”;
  • work in small teams or big teams with GIT.

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

This training session is for engineers, physicists, computer scientists and numerical analysts who wish to manage the development of their codes.

Prerequisites and registration

In order to follow this course, you need to:

  • be familiar with the use of basic Linux commands
  • the training can take place in French or in English depending on the audience, level B2 of CEFR is required.

To verify that the prerequisite is satisfied, the following questionnaire must be completed. 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.

Questionnaire 1 : https://forms.gle/oXakzdYaPZ4zSCx97

After completing the pre-requisite test and obtaining at least 75% correct answers, you can register:

The AVBP code from CERFACS at the heart of for PRACE projects from the 23rd call

CERFACS |  30 September 2021

Cerfacs is involved in three PRACE projects of the 23rd call for which hour allocation runs from 01/10/2021 to 30/09/2022. Researchers from ECL/LMFA UMR5509 (Ecole Centrale de Lyon) and IMFT (UMR 5502) laboratories have earned projects entirely based on the use of the LES solver developed by Cerfacs AVBP and involve the support of experts from the CFD and COOP teams underling the importance and effectiveness of collaborations between French labs and Cerfacs. Alexis Giauque from ECL/LMFA UMR5509 (Ecole Centrale de Lyon) has obtained not only one but two PRACE projects! The first project LESFAN (RA0101, 30 000 000 CPU hours on Irene/Rome TGCC) is based on the use of AVBP in the turbomachinery version to study the generation of noise by a fan of a real airplane engine. The second, PRACE-EDGES (RA0101, 40 000 000 CPU hours on Irene/Rome TGCC) focuses on LES modeling of dens gas in complex geometries. To do so, the LMFA Team has developed advanced thermodynamic closures in AVBP allowing the direct simulation of such flows. Laurent Selle from IMFT (UMR 5502) has received CPU hours for the GASTON project (RA0061, 30 000 000 CPU hours on Marenostrum BSC) which aims to study the structure of hydrogen flames in porous materials. For this, IMFT and Cerfacs will perform coupled simulations considering the reactive flow with AVBP as well as the conduction in the porous medium with AVTP which is known to play an central role in the flame stabilization process. Carlos Perez Arroyo from IMFT (UMR 5502) received 16 Mh CPU hours on Joliot-Curie Skylake partition to support his project WONDER.Read more
