摘要
首先给出了一种集成P2P模式的网格资源管理模型,针对此模型,提出了两阶段的网格任务调度方法,并分别利用层次颜色Petri网和颜色时延Petri网来进行建模。最后,分析了网格可达任务图,给出了集成P2P模式的网格任务最佳调度方案。
Firstly, the grid resource management model was described which was integrated P2P mode. Then, a two-phase grid task scheduling method was proposed. What's more, a hierarchical colored petri nets(HCPN) and colored timed petri nets were constructed. Finally, grid reachable task graph was analysed and a best grid task scheduling scheme was giren.
