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);

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.
