Enabling Grids for E-sciencE EGEE-II INFSO-RI “Training the trainers” tutorial, CERN, 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, training material, support system) and applications fully dedicated to dissemination purposes and pre- porting of new applications to EGEE Infrastructure –GILDA runs the latest production version of the gLite middleware (and also some pre-production ones) to make the transition from the t- Infrastructure to the e-Infrastructure easy and transparent –Everybody working in NA3 is welcome to use GILDA but, more importantly, to contribute to it in all possible ways
