EELA-2 Workshop – Grid Computing EU 6th International Conference on Open Access, Lilongwe, Malawi
Getting started
• 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
![Page 5: Grid INFN virtual Laboratory for Dissemination Activities](https://reader036.fdocuments.in/reader036/viewer/2022062617/54bf5d144a795952458b47a1/html5/thumbnails/5.jpg)

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

Test-bed
• Current test-bed (best effort maintenance)– 5 Grid sites– 148 CPUs– 455 TB of disk storage
• GILDA is “bookable on-demand” and “clonable on-demand”– Several GILDA-like insfrastructures are often created and last for a
short period of time

EELA-2 Workshop – Grid Computing EU 6th International Conference on Open Access, Lilongwe, Malawi
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.
![Page 43: Grid INFN virtual Laboratory for Dissemination Activities](https://reader036.fdocuments.in/reader036/viewer/2022062617/54bf5d144a795952458b47a1/html5/thumbnails/43.jpg)
EELA-2 Workshop – Grid Computing EU 6th International Conference on Open Access, Lilongwe, Malawi
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.
