GILDA is an international grid testbed that provides access to grid computing resources for training and demonstration purposes. It runs the latest version of gLite middleware and allows users to access grid services through various user interfaces without disrupting production systems. The summary outlines how to join GILDA, access its resources through different user interfaces, and find assistance documentation and tutorials to help users get started with grid applications on the testbed infrastructure.

- 44. 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.
- 45. 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.
