  1. French – Asia Grid Activities Dominique Boutigny Joint FJ / FK Particle Physics Laboratory Workshop • Credits : • Yonny Cardenas • Sylvain Reynaud

  2. History of the French – Asia Grid The Grid has been one of the major technical project within all the 3 French – Asia LIAs : FJPPL – FCPPL – FKPPL and to a lesser extent within the FVPPL (Grid deployment and tutorial in 2007, 2009 and 2011 ) Part of the activity was related to LCG • Another part was related to different projects (often multidisciplinary) and to computing development : • Distributed storage • Interoperability tools • CPU cycles After a few years of work it has been decided to build a common French / Korean Grid infrastructure, then Japan has been added We now have a functional global France / Korea / Japan / China distributed infrastructure at the disposal of the LIA projects

  3. Extra services Storage GLite / SRM storage system is often not flexible enough to satisfy standard users' needs  Considerable expertise at CC-IN2P3 and KEK on iRODS Deploy iRODS as an alternative Grid storage system Implement advanced data management policies / data replication Federation of iRODS systems between KEK and CC-IN2P3 VO sites Job Management A DIRAC service will be implemented to facilitate job submission and reliability


  5. A few examples of LIA projects using the France / Asia Grid • FCPPL : • Autonomous Cosmic radio detection system : TREND – Use GLite / iRODS • Cosmology projects in the framework of the Tsinghua Center for Astrophysics • FJPPL : • g-2 EDM project @ JPARC • Simulation GEANT4 • Data analysis and reconstruction • Data sharing • Requirements : 26 000 millions of CPU HS06-hours (preliminary estimate !!! ) – Enormous amount of CPU

  6. A few examples of AIL projects using the France / Asia Grid • FJPPL : • Project to setup a data recovery system based on iRODs for disaster recovery • See talk from Takashi • FKPPL : • A lot of activity in 2010 / 2011 on Lattice QCD, GEANT4 and drug discovery • Grid tutorials and trainings • FVPPL : • Analysis of Next Generation Sequence data • Grid-enabled Drug Discovery • Generation of Tsunami scenarii

  7. Interoperability tools a.k.a. SAGA • Ideally a standard user wants to have access to "unlimited" computing resources in a uniform and simple way • The reality is often much more complicated : • Different middleware • Different storage system • Different authentication mechanism • Grid Vs non Grid (simple batch system) • Cloud / virtualization • etc… A lot of work in France and Japan around the Open Grid Forum standard SAGA  see Takashi's talk

  9. Conclusions The Grid computing projects are very active within the 3 LIAs  They are now converging on a global coherent project built around the French – Asia Grid This computing infrastructure is fully functional and at the disposal of the scientific projects. New services will be added to increase the flexibility. Yonny Cardenas from CC-IN2P3 is providing an efficient support to help people to port their applications on the Grid.
