Cerfacs Enter the world of high performance ...

Algo-Coop Internal Meetings

The Algo-Coop team meetings are short UNFORMAL seminars of about 20 minutes, dedicated to the introduction of the work done or in progress by the Parallel Algo-Coop team members. They are useful for presenting work you did before arriving at CERFACS, for rehearsing before a conference, for sharing questions on current research with your colleagues…

Beginners are particularly welcome !

We remind you that these meetings are required to be english-spoken.

You can register at this mail address : yzel@cerfacs.fr

CERFACS cited in l’Usine Nouvelle, Industrie et Technologies

Corentin LAPEYRE |  25 November 2022

The work of CERFACS, in collaboration with SAFRAN, on the hybridization of physical simulation software with machine learning techniques, has been cited in the magazine l'Usine Nouvelle, and is included in a detailed write-up called "Simulation and machine learning combine their strengths" in the magazine Industries et Technologies this month. This work, supervised at CERFACS by Corentin Lapeyre, and at SAFRAN by Stéphane Richard, is at the forefront of developments in terms of exploiting artificial intelligence tools for the simulation and design of physical systems.Read more
