GILDA is a virtual Grid laboratory that provides training and resources for learning about Grid computing. It has over 1000 registered users from over 50 countries. GILDA offers video tutorials, workshops, and access to Grid testbeds to help researchers learn Grid technologies. Institutions can also set up their own local instances of GILDA to develop campus Grids or national e-infrastructures for research and education. GILDA has helped spread knowledge about Grid computing globally for almost 5 years and provides a model for training infrastructure that is widely adopted.

12. The “Triangle of Knowledge” Research & Development Innovation Education & Training Building e-Infrastructures is a waste if we don’t “build”, at the same time , their users. Along with e-Infrastructures, t-Infrastructures are also needed. e-Infrastructure t-Infrastructure t-Infrastructure

13. GILDA is a complete Grid test-bed Used to demonstrate/disseminate Grid computing GILDA is an international effort funded by multiple sources Adopted by several Grid projects worldwide It runs the latest version of the gLite middleware Using GILDA is free of charge What is GILDA?

14. Avoid to interfere with production Grid infrastructures Users can practice prior to run their codes on the production e-Infrastructures Provide guaranteed resources for training activities Prepare users for future middleware releases Support for pilot Grid Infrastructures Easy entry point for new users/communities Why t-infrastructure?

33. The SAGrid e-Infrastructure The infrastructure is under control. Jobs will run soon! Sites installed, currently testing: iThemba LABS North West University Wits School of Physics Site soon to be online: SAAO, SALT CHPC UCT-CERN Research Centre UKZN University of Stellenbosch Activities led by Bruce Becker (SAGrid National Coordinator) Central Services UFS UJ C4 UCT

34. Conclusions Kuala Lumpur, Malaysia

35. Almost 5 years of experience on Training; A ‘standard’ t-Infrastructure adopted by many projects; Several training formats: User, Site Admin, Tutors, Grid Schools, Custom events; Lots of training material: wiki, documents, video,… A ‘clonable’ Infrastructure for: Grid Schools, pilot infrastructures, new e-Infrastructures; GILDA can offer free technical support for anyone willing to organize local training events on Grid computing; It is helping to spread Grid Computing knowledge around the world.
