摘　　要：通过分析网格应用程序性能信息的预测策略,对几种主要预测策略作出了性能评价;结合应用历史信息预测法,以资源预测转化为应用程序预测策略为基础,提出了网格应用程序性能预测的修正模型.在动态网格环境下,本模型为调度决策系统提供了调度依据;使得网格资源的利用更加合理,改进了应用程序的执行性能.Performance evaluation of several main strategies was made via the analysis of the prediction strategies of grid application performance information, combined with historical information method, a correctional model of grid application performance prediction was proposed based on the prediction strategy of turning resource prediction into application prediction. The model of application performance prediction is the base for the scheduling system in dynamic grids environment; it makes the utilization of the grid resource more suitable and improves the executing performance of application program.
