GILDA is a complete Grid test-bed

GILDA is an international effort funded by multiple sources

Demonstrate/disseminate grid computing

Adopted by several Grid projects worldwide

It runs the latest version of the gLite middleware

Using GILDA is free of charge

Why t-Infrastructure? Avoid disruption of production systems of Grid projects Users can practice prior to run their codes on the production e-Infrastructures Prepare users for future middleware releases Easy entry point for new users/communities

Conclusions Cairo, Egypt

Summary and Conclusions (1/2) GILDA is a "de facto" standard t-Infrastructure adopted by several EU-FP6 and FP7 projects; 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-like Infrastructures; It is also a digital inclusion tool by helping to spread Grid Computing knowledge around the world.

GILDA is a "de facto" standard t-Infrastructure adopted by several EU-FP6 and FP7 projects;

It is also a digital inclusion tool by helping to spread Grid Computing knowledge around the world.

Summary and Conclusions (2/2) GILDA and Africa African scientific communities can use GILDA to “gridify” and run applications of local interest; Institutions can setup “clones” of GILDA locally to implement campus grids or even nation-wide e-infrastructures (we are already doing so in South Africa and Cuba); GILDA can offer free technical support for anyone willing to organize local training events on Grid computing It can be undergraduate courses, M.Sc courses, tutorials, Grid Schools etc.
