The “Triangle of Knowledge”

InnovationEducation & 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.

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?
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?

GILDA is also “clonable on-demand”– Institutions can setup “clones” of GILDA locally to
implement campus grids or even nation-wide e-infrastructures (“stand-alone” Grid);

The infrastructure is undercontrol. Jobs will run soon!

Conclusions
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.
