Management of Scientific Resources

Coordinated by GENCI (Grand Équipement National de Calcul Intensif), a call for proposals is launched during the fourth trimester of each year for the allocation of computing resources for the following year at the group of three national computing centres (CINES, IDRIS and TGCC).

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

The proposals are first examined by thematic scientific committees which, drawing on the technical expertise of the centres' applications assistance teams where necessary, make approval recommendations for granting computing hours. 

At the end of the year, an evaluation committee meets to review and validate these recommendations and proposes a distribution of calculation hours among the three national centres.  The final decision for the allocation of hours is made by the attribution committee, under the authority of GENCI.

A second call for proposals, extending from April to June, is made in order to study requests from current projects for resource use extensions as well as requests from new emerging projects.

Supplementary to these two principal procedures, IDRIS management continually studies specific requests for its resources and determines the allotment of limited numbers of hours as needed to current projects, to ensure their uninterrupted progress, and to new projects to facilitate their starting up.  

A Preparatory Access procedure for new projects allows the use of 15,000 hours on the SMP machine (named Ada) or 50,000 hours on the MPP machine (named Turing) to evaluate and improve the performance of targeted applications on these supercomputers.
