Grid Computing is intended to enable coordinated resource sharing & problemsolving in dynamic, multi-institutional virtual organizations. It deals with huge amount of distributed computation, data and information resources. By using the provided network connections, it tries to give the impression of having coherent virtual computing centre.
Enabling Grids for E-sciencE (EGEE) is currently the largest multi-disciplinary grid infrastructure in the world, which brings together more than 140 institutions to produce a reliable and scalable computing resource available to the European and global research community. At present, it consists of approximately 300 sites in 50 countries and gives its 10,000 users access to 80,000 CPU cores around-the-clock.
