网格资源调度研究

Research on Resource Scheduling in the Grid

在介绍网格资源管理的基础上,针对网格中的资源调度问题,分析和总结常见的三类资源调度策略;并结合应用任务的类型分析了面向应用的资源调度策略,探讨网格对不同类型任务的调度支持,着重分析协作型任务的调度问题。将协作型任务通过BPEL4WS规范描述后,分解为多个可以并发或串行执行的子任务,然后进行调度。基于此,提出了一个新的协作型任务调度方法。

In this paper we present resource management in the Grid briefly, with focus on resource scheduling, and analyze three categories of tactics used in application oriented resource scheduling. We then look into scheduling of different categories of tasks, especially the collaborative tasks, and advance a plan whose main idea is to decompose the collaborative task into parallel or sequential subtasks and schedule the subtasks.
