Workload and resource management are two essential functions provided at the service level of the Grid system. To improvement in global throughput need, effective and efficient load balancing are fundamentally important. We also check that what type of scheduling policy is used by that algorithm, because an efficient scheduling policy can utilize the computational resources efficiently by allowing multiple independent jobs to run over a network of heterogeneous clusters. In this paper, a dynamic grid model, as a collection of clusters has been proposed. An efficient scheduling policy is used, and its comparison with the other scheduling policy has been presented.
