Abstract

A computer cluster is a group of linked computers, working together closely so that in many respects they\nform a single computer. The components of a cluster are commonly, but not always, connected to each other through fast\nlocal area networks. Clusters are usually deployed to improve performance and/or availability over that provided by a\nsingle computer, while typically being much more cost-effective than single computers of comparable speed or\navailability. The major objective in the cluster is utilizing a group of processing nodes so as to complete the assigned job\nin a minimum amount of time by working cooperatively. The main and vital strategy to achieve such objective is by\ntransferring the extra loads from busy nodes to idle nodes.
