A short introduction to GRID
Gabriel AmorósIFIC
• “Grid computing (or the use of computational grids) is the application of several computers to a single problem at the same time — usually to a scientific or technical problem that requires a great number of computer processing cycles or access to large amounts of data.”
http://wikipedia.org
• Ideal world: one very powerful computer • classical computers: 2p vs quantum computers

• Power supply• Storage space• Communication lines
• Types of “GRIDS”:– Internet– Electric Power Lines– SETI@home– Large Hadron Collider Physics Experiments GRIDS
(ATLAS, CMS, ALICE, LHCb),…

The EGEE Project
• Funded by the European Commission, the Enabling Grids for E-sciencE (EGEE) project is the biggest Grid infrastructure project of the EU. The third two-year phase of the project started on 1 May 2008 and includes:
• A Grid infrastructure spanning about 250 sites across 50 countries
• An infrastructure of more than 68,000 CPU available to users 24 hours a day, 7 days a week,
• More than 20 Petabytes (20 million Gigabytes) of storage. • Sustained & regular workloads of 30K jobs/day, reaching up
to 150K jobs/day

Collaborating e-Infrastructures
Potential for linking ~80 countries by 2008
