Cerfacs Enter the world of high performance ...

Scientific challenges at CERFACS

Research at CERFACS is performed on 9 cross-functional axes, from high performance computing and advanced algorithms (numerical methods, code coupling, data assimilation, uncertainties) to expanding themes such as climate, environment , combustion, aeronautics.

Its application fields deal with scientific challenges structuring several decadal projects. These challenges meet the cross-functionnal CERFACS research areas conducted  by one or several teams.

  • The Cougar and Puma challenges respectively aim at the simulation of the unsteady functioning of a complete engine of gas turbine and of a whole aircraft in realistic flight conditions.
  • The Declipp challenge deals with decadal prediction and climate variability using climate modeling and a coupled ocean-atmosphere model.
  • The Decola challenge is about simulating unsteady combustion of rocket engines in realistic “supercritical” named conditions.
  • The Modest challenge gathers specialized modeling activities about environment and security. This in order to better characterize natural and industrial risks in terms of monitoring, scenarios and real-time tracking.

More challenges may be created in consultation with the CERFACS shareholders.


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

Brigitte Yzel |  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


CERFACS |  4 July 2022

CERFACS will participate to the Paris meeting dedicated to the memory of Roland Glowinski from July 5th to 7th. Thierry Poinsot will present the advances of HPC in the field of energy and combustion. Roland Glowinski was CERFACS direcfor for 3 years in the 90s and largely shaped present activities of our research center.Read more
