摘　　要：在网格作业调度中,由于用户作业与资源频繁变化而产生的动态性,现有的调度策略又存在资源响应时间短或网格带宽少的情况,而导致这些资源在作业调度中会产生资源过时的现象,因此需要一种有效的作业调度策略.提出了一种动态资源调度策略,策略根据资源响应时间和状态更新时间对资源进行调度,并将所提出的策略与基于时间的策略进行对比分析.实验结果表明,该策略能显著提高网格的性能.In grid job scheduling,the user assignments and frequent changes of dynamic resources,existing resource scheduling strategy and short response time or grid less bandwidth,and cause these resources in job scheduling will produce the phenomenon of resources out of date,so we need an effective job scheduling strategy.In this paper,a dynamic resource scheduling strategy is proposed.The resource is scheduled according to the resource response time and the state update time,and the proposed strategy is compared with the time-based strategy.Experimental results show that the proposed strategy can significantly improve the performance of the grid.
