The Grid initiative provides an infrastructure for distributed computation among widely distributed high-performance computers. This will allow for exchanging and processing very large amounts of data. There are a huge number of applications that are geographically distributed such as multi-point radio facility for astrophysics, space physics, atmospheric physics, and radio research, utilizing very high performance Grid Computing. It is expected that similar applications to become important in commercial settings, initially for scientific and technical computing applications and then for commercial ...
