Grid Resource Organization and Discovery Based on Hyper Topology Space

Resource management is one of the basic and key aspects in grid computing, especially in resource organization and discovery, which are very important for good sharing and using of Grid resources. This paper reviews the mechanism and architecture of Grid resource management model from hyper topology space, and researches how to describe resources, abstract resources, provide unified system images and discovering resources. And then a formal model of Grid resources with three layers, primitive resource layer, aggregating resource layer and service resource layer, is presented. Each layer has different forms and topology structures. Upper layer can be formed from lower one by the proposed method of aggregating class reactions. Over the organization of the model, the scheme of resource discovery is also described. Analyses show that this approach could enhance the usability, modularity, transparency and automation of Grid resource management system.
