Cerfacs Enter the world of high performance ...

CERFACS is involved in the NextSim project

  19 July 2021

The primary objective is to increase the capabilities of Computational Fluid Dynamics tools on extreme-scale parallel computing platforms for aeronautical design. The Kick-Off Meeting took place on 12 March 2021. 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. For more information, please visit  EuroHPC website : Project webpage :

Research on quantum computing at CERFACS recognized with an award

  1 July 2021

A team composed of researchers from CERFACS and LIRMM (Laboratoire d'Informatique, Robotique et de Micro-électronique de Montpellier) is one of the winners of the Open Science Prize challenge, a contest organised by IBM. The challenge aimed at improving the precision of some quantum circuits that are deemed important for the development of quantum computing in the future. With more than 70 participants and 30 teams, this international challenge showed that it was possible to substantially improve the preparation of a specific quantum state, called "graph-state", that may be a crucial step for implementing error correcting codes using quantum computing.

CMIP6 debriefing workshop – May 2021: a stocktaking and foresight exercise that highlighted the major and long-term investment of the CNRM-CERFACS group in the latest climate model intercomparison international exercise

  9 June 2021

The participation of the CNRM-CERFACS group in the international coupled global climate model intercomparison exercise CMIP6 was debriefed on 10 and 11 May. Since the mid-1990s, the various phases of the Coupled Model Intercomparison Project (CMIP), supported by the World Climate Research Programme (WCRP), have enabled climate science to make significant progress, feeding into the IPCC reports, supporting regional climate modelling activities and downstream climate services. On the balance sheet, the participation of CNRM-CERFACS in the extremely demanding CMIP6 exercise has resulted in a large-scale, high-quality contribution in terms of climate simulations, thanks in particular to the strong commitment of researchers and engineers, the quality of support services and national and international collaborations. The activities mainly took place over the period 2013-2020. Initially, the production environment ("workflow") was set up and the coupled climate models were assembled by capitalising on the development of components (atmosphere, ocean and continental surfaces) carried out over the long term. The actual production of simulations was spread over 2018-2020. During the debriefing, perspectives (scientific objectives, model development, organisation) were drawn up with a view to a new participation of CNRM and CERFACS in CMIP

New regional climate projections for metropolitan France

  11 February 2021

Cerfacs collaborated with Météo France and the Institut Pierre-Simon-Laplace (IPSL) to produce the DRIAS climate dataset, which presents a wide range of possible climate changes for metropolitan France for three periods of the 21st century (2021-2050, 2041-2070 and 2071-2100) and three greenhouse gas emission scenarios.

New research group “Theory and Climate”

  1 February 2021

CECI is involved in the development of a new research group (GDR for “Groupement De Recherche”) entitled “Theory and Climate”. This GDR aims at bringing together the entire community of theorists (mathematicians, physicists, computer scientists, data scientists, etc.) working on climate sciences, with the goal of developing and sharing innovative concepts and tools relevant for a better understanding of climate dynamics. This GDR is interdisciplinary and involves several CNRS research institutes as well as most of French organizations working in these fields. CECI plans to contribute to issues related to climate dynamics and applied mathematics such as data assimilation and machine learning. Moreover, there are strong links between this GDR and the LEFE-INSU actions, in which CECI researchers are active (LEFE-IMAGO and LEFE-MANU actions). More information here:

Swings oceanographic campaign

  11 January 2021

Christophe Cassou, a researcher at the Cerfacs/CNRS joint laboratory (CECI: Climate, Environment, Couplings and Uncertainties) will take part in the Swings oceanographic campaign, involving 48 scientists and led by two CNRS researchers. It will take place in the Southern Ocean on board the Marion Dufresne II of the French Oceanographic Fleet (FOF), operated by Ifremer, from 11 January to 8 March. 2 months sea explore southen oceans
