> 中文摘要: 在利用工作站群集系统进行的协作模式并行计算中,任务调度在很大程度上决定并行计算的性能.本文给出了一个任务调度的模型和算法,它考虑了协作模式并行计算中任务间的同步时间、通信时间、数据加载及结果收集时间.根据这个调度模型,可以选择一组并行执行时间最短的工作站,从而获得较好的并行计算性能.
Abstract:In the cooperative concurrent computing on a workstation cluster system, task scheduling determines the performance in large degree. This paper gives a model and an algorithm of task scheduling, in which the costs of synchronization, communication, loading data and collecting results are considered. Using this scheduling model, a group of workstations with the shortest executing time of jobs can be selected to obtain better performance of parallel computing.
