On Grid’5000

Many success stories in combinatorial optimizations:-solve the n-Queens problem for n=25, in 2005-solve (exact solution) of the flowshop Ta056-50-20 instance

one of the most remarkable one, in 2008:Grid’5000 was used to design and improve the algorithm used in the first computer victory against a professional Go player (9x9) in the last Paris tournament!

ANR supports HPC!

• HPC is seen as an important challenge to increase the competitiveness of the industry and the development of science

• Numerical simulation is the third pillar (in silicio) to develop knowledge (in vitro and in vivo experimentations, theory)

• Numerical simulation paves the way for new scientific discoveries

• Available 2009 funding:• Programme COSINUS – Numerical simulation

• Programme BLANC / JCJC – long term, young researchers

• Programme Materials & Processes – multiscale simulation

• Programme ARPEGE – large-scale infrastructures

• Programme DEFIS – Architectures, algorithms, languages

• Programme P3N (nano) – simulation for nanomaterials

• And in other programmes….

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

27

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

28

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 »
