Scientific management of Resources

Coordinated by GENCI (Grand Équipement National de Calcul Intensif), a call for proposals, common to the three national computing centres (CINES, IDRIS and TGCC), is organised twice each year for the purpose of allocating computing hours. These hours are valuable for one year. During each call, requests may be submitted for calculation hours for new projects, to renew an existing project or to request supplementary hours for an allocation received during the preceding call.

Requests for resources are made with the DARI form (Demande d'Attribution de Ressources Informatiques) through a common web site for the three computing centres (see Requesting resource hours on IDRIS machine).

The proposals are examined from a scientific perspective by the Thematic Committees who draw on the technical expertise of the centres' application assistance teams as needed. Subsequently, an evaluation committee meets to decide upon the resource requests and make approval recommendations to the Attribution Committee, under the authority of GENCI, for distributing computing hours to the three national centres. 

Between the two project calls, IDRIS management studies the requests for supplementary resources as needed (“demandes au fil de l'eau”) and attributes limited hours in order to avoid the blockage of on-going projects.

A procedure called Preparatory Access is available to new projects for the purpose of evaluating and improving the performance of the concerned applications on IDRIS supercomputer. Through theses Preparatory Access, projects may benefit from:

• 50000 CPU hours on CPU partition of Jean Zay
• 1000 GPU hours on GPU partition of Jean Zay
