4. GILDA t-Infrastructure
Why t-infrastructure?
Training is necessary!
e-Infrastructure for production
t-Infrastructure for training
Need guaranteed response for tutorials; limit the vulnerability of production systems
use training grid
have training CA
able to change middleware to prepare participants for future releases on production system
need safe resources for installation training
easy entry point for new communities

5. The “global” grid coverage
At Feb review:
100 sites, 10K CPUs
1st gLite release foreseen for March’05
6 domains and

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

7. All gLite services on GILDA

26. 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
