One important To run efficiently, grid applications need to be scheduled and reason is the lack of a simple and high-level application program- then executed in such a manner that the performance of the ming toolkit, bridging the gap between existing grid middleware and application-level needs. The Grid Application Toolkit (GAT), resources which are actually used are properly taken into as currently develope
