网格资源管理与调度研究

Research on Grid Resource Management and Schedule

网格计算是近年来得到快速发展的广域网格计算技术，其目标是把因特网整合成一种超大规模的巨大计算机系统，以实现计算资源，存储资源，信息资源．知识资源的全面共享，资源管理与调度是网格计算中的核心部分，在本文介绍网格资源管理，分析了三类资源调度策略；并提出了一个基于信任度的资源调度策略，详细描述了基于信任度的资源调度策略的算法实现．把服务质量有机集成在资源调度策略当中去．

Grid computing is a fast developing wide area net work computing technique. Its objective is to combine internet into a whole very large-scale computer system in order to share all computing resources,storage resources, information resources and knowledge resources, and resources management and schedule is core of grid computing, in this article, grid resource management is introduced, three kinds of resources schedule strategy is analyzed, and a schedule strategy based on the trusting degree is provided, the algorithm of the resources schedule strategy based on the trusting degree is described in details ,so the quality of service is integrated with the resources schedule strategy organisely.
