  1. The GILDA t-Infrastructure Claudio Cherubino INFN - Catania

  2. Getting started • Grid INFN Laboratory for Dissemination Activities • Demonstrate/disseminate grid computing • Adopted by several Grid projects worldwide • It runs the latest production (stable) version of LCG grid middleware but it is also adopting gLite in order to make the transition to the new middleware smoother and easier • It is free

  3. The GILDA Project – web portal https://gilda.ct.infn.it

  4. Why t-Infrastructure? • Avoid disruption of production systems of Grid projects • Prepare participants for future middleware releases • Easy entry point for new users/communities • Provide guaranteed response for tutorials

  5. GILDA Test-bed ~20 sites in 4 continents

  6. List of gLite services

  7. Public GRID Demonstrator • https://glite-demo.ct.infn.it

  8. 1 3 4 2 Before trying GILDA… • First Steps: • Ask for a GILDA personal certificate • Load the certificate in your browser • Accept Use Policy • Subscribe to the GILDA Virtual Organisation

  9. The GILDA User Interface Plug&Play

  10. The GILDA Virtual Services Wiki pages also available More than 2 TB of training material already downloaded!

  11. Training material Wiki page Video tutorials Step by step instruction Support system GILDA Forge User Assistance

  12. Set of tools for generating high quality raster images of molecules Applications: RASTER-3D

  13. “Sonified” data from geophysical data collected by digital seismographs placed on volcanoes. Applications: Volcano Sonification Etna, Italy Tungurahua, Ecuador (Picture: g1.globo.com) (Picture: M. Monzier IRD/IG-EPN)

  14. Seismograms Melodisation Applications: Volcano Sonification

  15. Employed for the treatment of some kind of ocular tumours Used to calibrate the proton beamline in reality Applications: hadronTherapy

  16. Satellite image rendering program Input: ASCII file in DEM format (Digital Elevation Model) Output: VRML file Applications: DEMTOOLs

  17. Stats • Used in more than 180 tutorials • 7693 certificates issued • > 3 TB of videos and Virtual Grid services downloaded • Web portal: 768.880 hits in 2006

  22. Summary and conclusions • GILDA is a virtual laboratory for dissemination of grid computing: • It is a “de facto” standard t-Infrastructure adopted both by EGEE and many EU-FP6 projects (EELA, EUCHINAGRID, EUMEDGRID, EUINDIAGRID, ICEAGE, etc.) • It is a complete suite of grid elements (test-bed, CA, VO, monitoring system, web portal, user interfaces, support system) and applications fully dedicated to dissemination purposes and pre-porting of new applications to EGEE Infrastructure • GILDA runs latest production version of the gLite middleware to make the transition from the t-Infrastructure to the e-Infrastructure easy and transparent
