摘 要：Grid computing is a special kind of branch network computing which has important innovative ideas and great potential of *** forms a large use of each other and co-operation high-performance computing network by interconnecting a number of computing resources,data resources of the wide area network as well as other *** grid system is heterogeneous and dynamic,and the different resource requires of the applications running on grid system,grid task scheduling is extremely ***,how to syncopate the task will directly affect the overall scheduling performance of the task in a grid *** implementation process,different tasks need different resource,this article mainly aims at the demand of CPU and memory to establish a performance evaluation *** the evaluation results of CPU and memory,establish a rational task segmentation strategy to improve the quality of service,and realize grid load balancing,low communication complexity and high reliability between tasks,which achieve the purpose of minimizing the task execution time.
