French – Asia Grid Activities

Dominique Boutigny

Joint FJ / FK Particle Physics Laboratory Workshop

history of the french asia grid
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

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

a few examples of lia projects using the france asia grid
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
a few examples of ail projects using the france asia grid
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
interoperability tools a k a saga
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

conclusions
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.
