On the premise of guaranteeing the users's Quality of Service(QoS) requirements and to research the method how to promote the grid system performance,a global utility heuristic schedule strategy for grid meta-task is proposed.The immediate schedule arithmetic MGU and batch schedule arithmetic Global USufferage are designed.Simulation experimental results show this strategy can get higher user satisfaction,and meanwhile ensure the system throughput and stability.
