  23. OthersMissions • To promote simulation and high performance computingin fundamental and industrial research • To promote the organization of an European HPC area and to participate to its achievements  • To open its equipments to all interested scientific communities, academic or industrial, national, european or international GENCI is the french representative in

  24. INRIA strategy in HPC (cont’d) • European • Participation to PRACE-1IP (within GENCI) • Participation to EESI (Exascale initiative led by EDF R&D) • International • Associated teams with key HPC players • Joint laboratory with UIUC-NCSA

  25. INRIA and the Joint-Lab on PetaScale Computing • Research and development in for Peta-ExaScale HPC needs international collaborations • PetaScale Software are already raising many significant research problems • ExaScale system design will open a very large domain of research and will require a huge effort from the community • Projects like PRACE in Europe and IESP at the international level help establishing clear roadmaps and focusing on the right problems • The economic situation is a threat for very large, single country, projects • UIUC and NCSA with the BlueWaters project are in the forefront of research and development for Sustained PetaScale • Strong opportunity for INRIA researchers to participate and contribute to the research on Key algorithmic and software challenges in PetaScale computing. • Sustained PetaScale means a clear understanding of the applications and the design of truly scalable software • May increase at INRIA the facet of HPC Research related to production

  26. Technology Transfer • A stream of Spin-offs • Kerlabs (OS) • Caps Entreprise (GPGPUs compiler) • ActiveEon (distributed objects for HPC) • SysFera (Tools) • INRIA/GENCI Initiative, with French competitiveness clusters, « national coordinated HPC program for SMEs »
