网格资源的竞争调度策略

Study of competitive and scheduling strategy of grid resources

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。

According to unreliable grid calculation caused by unreliable grid notes, this paper points out correcting 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 unreliable grid notes. Based on competitive strategy grid task scheduling mechanism and on the gruaranteeing of system, 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.
