Medal of the Academy of Air and Space: 3 CERFACS researchers awarded !

11 July 2022

The Air and Space Academy awarded Carlos Pérez Arroyo, Gabriel Staffelbach and Jérôme Dombard with the Vermeil medal 2022, to honor the excellence of their work in the realization of the FULLEST project, the first high-fidelity simulation of an aircraft engine. Thanks to PRACE for awarding the access to the Joliot-Curie supercomputer (GENCI hosted at CEA/TGCC) and to DGAC for the funding of the ATOM project (No 2018-39) led by SAFRAN Tech. FULLEST also benefited from developments done in European projects:  EXCELLERAT (H2020 823691) and EPEEC (H2020 801051).   Read more

TERATEC award, innovation category

27 June 2022

The TERATEC 2022 Simulation and Digital Technologies Trophy, innovation category, was awarded to Catherine Lambert on June 14 during the TERATEC 2022 Forum. This trophy rewards CERFACS and Safran for the development of the AVIP code capable of simulating new generations of electric motors for satellite propulsion. Thanks to the use of unstructured meshes and innovative numerical techniques, AVIP makes it possible to build digital twins of real engines. Congratulations to all who contributed to the project: Willca Villafana (Cerfacs), Guillaume Bogoposlky (Safran), Benjamin Laurent (Safran), Olivier Vermorel (Cerfacs), Bénédicte Cuenot (Cerfacs) And a big thank you to our partners: INRIA and Ecole Polytechnique (POSEIDON project)   Read more

Catherine Lambert awarded Officer in the national order of Merit

31 May 2022

Catherine LAMBERT, President of Cerfacs, has been promoted to the grade of officer in the national order of Merit, on the proposal of Mrs. Frédérique Vidal, Minister of Higher Education, Research and Innovation. Antoine PETIT, President and CEO of the CNRS, presented the insignia to Catherine LAMBERT during a ceremony that brought together many actors from the space, aeronautics, environment and digital sectors. Antoine PETIT: "Catherine's interpersonal skills, her ability to step back and understand very different environments (research, industry, politics) in order to develop a collective vision are the hallmarks of her career. Catherine is one of those people with whom you naturally feel confident, with whom you want to build something that goes beyond all of us to go further. With this honor, the Cerfacs teams are also rewarded. Read more

Press releases on the NextSim EuroHPC project

9 February 2022

Press talks about the NextSim EuroHPC project. CERFACS is involved in two major points. The first topic is to extend the numerical capabilities of the code to perform scale-resolving simulations of jet noise configurations on exascale supercomputers. The second focus is to exploit data from these simulations by extracting or visualising relevant physical information during the computation. CERFACS is involved in the NextSim project (). The primary objective is to increase the capabilities of Computational Fluid Dynamics tools on extreme-scale parallel computing platforms for aeronautical design. This project has received funding from the European High-Performance Computing Joint Undertaking (JU) under grant agreement N° 956104. The JU receives support from the European Union’s Horizon 2020 research and innovation programme and Spain, France, Germany. This project has received funding from the Agence Nationale de la Recherche (ANR) under grant agreement N° ANR-20-EHPC-0002-02. For more information, please visit  Read more

Two new partitions bring the peak power of the Cerfacs computer to 1 Pflop/s.

1 February 2022

A hybrid partition composed of 8 quadri-GPU Nvidia A30 nodes and a computational partition comprising 40 IceLake nodes were put into production in early January. These two new partitions strengthen our simulation and research capabilities by increasing the peak performance of the Cerfacs Lenovo computer to 1 Pflop/s. Read more
