网格资源的超拓扑空间模型

Grid Resource Model Based on Hyper Topology Space

为了更好地共享和使用网格资源,资源模型已经成为网格计算的重要研究问题之一。论文从超拓扑空间的角度重新审视了网格资源模型的内在机理与结构,对资源的描述、抽象以及单一系统映像方法进行了深入的研究,提出了一个形式化资源模型,具有三层结构,分别是:特征信息层、特征处理层和功能层。各层有着不同的组织形式与拓扑结构,并且进一步可细分为若干亚层;利用所提出的聚类方法,上层结构可由下层自动形成。应用分析表明,该模型能够有效地提高网格资源管理系统的可用性、模块性、透明性和自动化。

For sharing and using of Grid resources,resource model has become one of important research problems in Grid Computing.This paper reviews the mechanism and architecture of Grid resource model from hyper topology space, researches how to describe resources,abstract resources and provide unified system images,and then presents a forr/lal resource model with three layers,character information layer,character processing layer and functions layer.Each layer has different forms and topology structures and can be divided to several sub-layers again.Upper layer can be formed from lower one automatically by the proposed method of clustering reactions.Applications and Analysis show this model could enhance the usability ,modularity ,transparency and automation of Grid resource management system.
