Computational grid

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

Computational grids are sometimes described as useful only for computation / computation tasks, but in fact they are capable of handling many research projects that require large amounts of CPU time, large amounts of memory, or the ability to communicate in real time. In some of these cases, supercomputers are unable to meet these requirements. A computational grid is a convenient way to use many devices in combination.

A computing grid shares some properties with the cloud in the Cloud computing.
