There is in France a variety of computing resources available to the scientific community, adapted according to the scientific needs and the size of the projects.

AT THE REGIONAL LEVEL

At the regional level, these are what are known as Tier2, with a global computing power around 1 petaflop/s and generally operated in university computing centres. With the Equip@meso project, supported by GENCI, some ten of these, spread throughout France, are going to be significantly enhanced in order to deliver a much better service.

AT THE NATIONAL LEVEL

At the national level, there are the so-called Tier1 resources, offering power at the level of petaflop/s, in the three national centres with operations coordinated by GENCI.

AT THE EUROPEAN LEVEL

Finally, at the European level, the so-called Tier0 resources, at multi-petaflop capacity, can be accessed through the PRACE infrastructure of which France, represented by GENCI, was one of the founding members. Following the EC communication on 15 February 2012 saying that HPC is a strong enabler for both scientific discoveries and industrial innovation in Europe, the Competitiveness Council of May 2013 went in the same direction by adopting conclusions on HPC. It was the first time that such conclusions on HPC were adopted both by member states and the European commission.
