Cerfacs Enter the world of high performance ...

Research at CERFACS

The CERFACS’ research strategy aims at anticipating the structuring challenges that answer scientific, technological or society issues to which  four major fields are faced for the future decades.


Research activities at CERFACS

Research is declined in nine axes :

High Performance Computing

Data assimilation and optimization

Numerical methods and linear algebra





Coupling and interfaces


Challenges at CERFACS

Five big challenges benefit from the CERFACS teams’ interdisciplinary diversity of skills and knowledge :

• Decadal weather forecasts : Declipp challenge

• Modeling for environment and security : Modest challenge

• Simulation of space propulsion : Decola challenge

• Simulation of a turbine operation : Cougar challenge

• Simulation of a whole-body aircraft : Puma challenge

67 climate modelling groups use OASIS3-MCT to assemble more than 80 coupled applications

superadmin |  10 September 2019

OASIS3-MCT is a coupler of codes developed at Cerfacs and used around the world, mainly for climate modelling applications. Our last survey confirms that OASIS3-MCT is used by 67 modelling groups to assemble more than 80 different coupled applications over the 5 continents. These applications include global or regional configurations of ocean and atmosphere models but also sea ice, sea level, wave, ocean biogeochemistry, land, vegetation, river routing, hydrological and atmospheric chemistry models. OASIS3-MCT is used in 5 of the 7 European Earth System Models participating to the 6th Coupled Model Intercomparison Project (CMIP6) that produces the climate simulations forming the basis of the next report of the Intergovernmental Panel on Climate Change (IPCC)”Read more
