Grid computing allows, controlled and coordinated resource sharing and problem solving in dynamic, multi-institutional virtual organizations. Grids are categorized in to two, as Computational grid and Data grid. In computing grid, allocating resources to the tasks based on its requirements and task scheduling is an important issue. Generally, the task scheduler assigns tasks to a suitable resource. The nodes with better performance would be assigned first for execution. When the load on a grid was high, and all resource with a better performance is assigned, other tasks have to be assigned to the resource with unsuitable performance. To improve the performance and throughput of the system, it is required to assign the tasks to a suitable and lower fault rate processor.
