| 摘 要： | 针对由于网格结点不可靠而引起网格计算不可靠的问题,提出了网格任务的分级竞争调度策略和网格计算中的容错方法,研究了网格计算的可靠性和时效性。基于竞争策略的网格任务调度机制,在保证网格计算的可靠性基础上,自动消除可靠性差、资源能力弱的结点对系统性能的影响,使得网格计算的时效性较优和总体性能最优。

| Abstract: | According to unreliable grid calculation caused by unreliable grid notes,this paper points out cor- recting mistake methods in multi-grading competitive and scheduling strategy and grid calculation of grid task, studies reliability and time effect of grid calculation and solves the problems in original methods becaues of unre- liable grid notes.Based on competitive strategy grid task scheduling mechanism and on the gruaranteeing of sys- tem,the notes which are unreliable and have weak resources are automatically removed to make optimization of the whole capability and more optimized of time effect in grid calculation. |

| Keywords: | multi-grade competition scheduling strategy correcting mistake method grid notes grid system grid calcuation reliability |
