Grand Equipement National De Calcul Intensif

GENCI is an agency in charge of the coordination of principal French equipments in high performance computing. GENCI is an association of five partners: French Ministry of Higher Research and Education, CEA, CNRS, French universities represented by the CPU “Conférence des Présidents d’Universités” (with the Universities Computing Centre, CINES) and INRIA.

Created in January 2007, GENCI has had the following missions:

  • Set in place and coordinating the major computer equipment for the French computer centers for civilian research, by providing for their financing and assuming their ownership
  • Promote the organisation of European high performance computing and participate to its actions,GENCI is the french representative into PRACE AISBL, HPC Europa2 and EESI
  • Promote the use of modelling, simulation and high performance computing in fundamental and industrial research
  • Perform all research required for developing and optimising the utilisation of computing equipment
  • Open the equipment it owns to all interested scientific communities, academic or industrial, national, European or international

Since 2007 GENCI and its associates have been able to multiply by a factor of 30x the available high performance computing resources available to french scientists from 20 to 600 TFlops. These resources are operated daily by 3 national centers : CCRT (for the civil activities of CEA at Bruyères-Le-Chatel), CINES (for the french Universities at Montpellier) and IDRIS.(for CNRS at Orsay).

Biggest facilites include a 267 TFlops SGI system at CINES (called Jade), a 139 TFlops IBM BlueGene/P system at IDRIS (called Babel), a 103 TFlops + 192 TFlops (single precision) hybrid BULL system at CCRT (called Titane) and a 67 TFlops IBM Power7 system at IDRIS (called Vargas).

GENCI is also the french representative into the PRACE AISBL and one of the 4 hosting partners with Germany, Italy and Spain. GENCI recently procured to BULL a 1.6 Pflops x86-64 Tier-0 system which will be installed in 2 phases starting end of 2010 into a new computing center (called TGCC) operated by CEA-DAM at Bruyeres-Le-Chatel.
