Abstract: 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.

Key words: grid application program, performance prediction, execution time, correctional model
