Computational Grid

A computational grid is a loose network of computers linked to perform grid computing. In a computational grid, a large computational task is divided up among individual machines, which run calculations in parallel and then return results to the original computer. These individual machines are nodes in a network, which may span multiple administrative domains and may be geographically distant. Each of the nodes may be thought of as a discrete system that can perform work and has access to a network. Computational grids are often more cost-effective than supercomputers of equal computing power.
