CERFACS (the European Centre for Research and Advanced Training in Scientific Computation) is based in Toulouse, France. It is a research organization that develops advanced numerical simulations of large scientific and technological problems, using the most powerful computers presently available. Approximately 100 people, from 10 different countries, work at CERFACS in interdisciplinary teams, both for research and advanced training. Their disciplines include physics, applied mathematics, numerical analysis, and software engineering.
The CFD team at CERFACS comprises more than 50 scientists, including some 30 PhD students. Its scientific activities are centred on the development of numerical tools and physical models for advanced research with industrial applications. The main fields of application are turbulent reacting flows. Together with its academic collaborators (Ecole Centrale Paris, Institut Français du Pétrole, and the CTR research centre at Stanford University), CERFACS have created novel Large Eddy Simulation (LES) tools for the study of combustion instabilities. Long-standing industrial collaborations have been established with Snecma Moteurs, Turbomeca and Gaz de France, as well as, at a European level, with Siemens PG in Germany and Alstom in Switzerland.
Computer resources located at CERFACS comprise an IBM Cluster (56 blades JS21, 2.24 Tflops, 224 computing cores), one Cray XD-1 (576 peak GFlops, 120 AMD Opteron 2.4 Ghz) and an AlphaServer SC4 (40 EV68-1Ghz processors, 80 peak Gflops). Moreover, CERFACS has access to major European high performance computing centers: CEA (Bull Tera-10), CINES, IDRIS, Météo France as well as to MareNostrum (one of the most powerful supercomputers in Europe, installed at the Barcelona Supercomputing Center).
