  • 11. Motivation Beijing, China
  • 12. The “Triangle of Knowledge” Research & Development Innovation Education & Training Building e-Infrastructures is a waste if we don’t “build”, at the same time , their users. Along with e-Infrastructures, t-Infrastructures are also needed. e-Infrastructure t-Infrastructure t-Infrastructure
  • 13.
    • GILDA is a complete Grid test-bed
    • Used to demonstrate/disseminate Grid computing
    • GILDA is an international effort funded by multiple sources
    • Adopted by several Grid projects worldwide
    • It runs the latest version of the gLite middleware
    • Using GILDA is free of charge
    What is GILDA?
  • 14.
    • Avoid to interfere with production Grid infrastructures
    • Users can practice prior to run their codes on the production e-Infrastructures
    • Provide guaranteed resources for training activities
    • Prepare users for future middleware releases
    • Support for pilot Grid Infrastructures
    • Easy entry point for new users/communities
    Why t-infrastructure?
  • 15. https://gilda.ct.infn.it The GILDA Web portal
  • 16. Figures Istanbul, Turkey
  • 17. Figures >1000 users registered in the GILDA VO >14,000 certificates issued since 2004. More than 30% renewed at least once. 341 tutorials in 54 countries since 2004.
  • 18. The GILDA test-bed ~ 20 sites in 4 continents # of Sites may change in time (they are managed on a “best effort” basis) More sites will soon be available in LA and South Africa
  • 19. User Assistance Cairo, Egypt

    • Training material
      • Wiki page
      • Video tutorials
      • Step by step instructions
    • Support system
    • GILDA Forge
    User Assistance
  • 21.
    • Customized training events: from 1 day tutorial to 2 weeks Grid School
      • Tutorials for users, system admin. & trainers
    • Can be done without outside internet connection
    • “ Bookable on-demand”: any institution can request a tutorial.

  • 26. “ Virtuous cycle” of applications La Plata, Argentina
  • 27. Dissemination Training events “ Gridification” Deployment on large Infrastructures and inclusion in the portfolio of demonstrative applications “ Virtuous cycle” of applications
  • 28. Demonstrative Applications
  • 29.
    • “ Sonified” data from geophysical data collected by digital seismographs placed on volcanoes.
    Application: Volcano Sonification Etna, Italy
  • 30. Etna, Italy Application: Volcano Sonification Seismograms Melodisation 5 sec = 20h processing in 1 simple PC
  • 31. Multiplying GILDA Lilongwe, Malawi
  • 32.
    • GILDA is also “clonable on-demand”
      • Institutions can setup “ clones ” of GILDA locally to implement campus grids or even nation-wide e-infrastructures ( “stand-alone” Grid );
    Multiplying GILDA
      • Cuban stand-alone Grid (EELA-2 project)
      • The SAGrid e-infrastructure
  • 33. The SAGrid e-Infrastructure The infrastructure is under control. Jobs will run soon!
    • Sites installed, currently testing:
    • iThemba LABS
    • North West University
    • Wits School of Physics
    • Site soon to be online:
    • SAAO, SALT
    • CHPC
    • UCT-CERN Research Centre
    • UKZN
    • University of Stellenbosch
    • Activities led by Bruce Becker

  • 34. Conclusions Kuala Lumpur, Malaysia
  • 35.
    • Almost 5 years of experience on Training;
    • A ‘standard’ t-Infrastructure adopted by many projects;
    • Several training formats: User, Site Admin, Tutors, Grid Schools, Custom events;
    • Lots of training material: wiki, documents, video,…
    • A ‘clonable’ Infrastructure for: Grid Schools, pilot infrastructures, new e-Infrastructures;
    • GILDA can offer free technical support for anyone willing to organize local training events on Grid computing;
    • It is helping to spread Grid Computing knowledge around the world.
