A short introductionto GRID Gabriel Amorós IFIC
“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: oneverypowerfulcomputer • classicalcomputers: 2p vs quantum computersqp • Powersupply • Storage space • Communicationlines

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
What is happening now? Real Time Monitor • Java tool • Displays jobs running (submitted through RBs) • Shows jobs moving around world map in real time, along with changes in status (snapshot 16 January 2007) http://gridportal.hep.ph.ic.ac.uk/rtm/
Who is using EGEE? • >200 VOs from several scientific domains • Astronomy & Astrophysics • Civil Protection • Computational Chemistry • Comp. Fluid Dynamics • Computer Science/Tools • Condensed Matter Physics • Earth Sciences • Fusion • High Energy Physics • Life Sciences • Further applications under evaluation
ESRs at CERN: • VassilikiKanellopoulos (and MedAustron) • FaustinRoman (and IFIC) • Daniel Abler(and Oxford)
