Relative Information in Grid Information Service and Grid Monitoring Using Mobile Agents

Abstract

Grid computing is consolidated as a technology capable of solving scientific projects of our century. These projects’ needs include complex computational and large data storage resources. The goal of grid Computing is to share these resources among different institutes and virtual organizations across high-speed networks. The more resources there are the more difficult it gets to monitor them and to assure users find the best resources they are looking for. We introduce the concept of relative information to enhance grid information and grid monitoring services. Resource relative information is information that is not only gathered from the resource itself but also that takes into account other resources of the same type. The resource is not described in terms of the resource local information but also relative to other resources. We present a framework based on mobile agents that enables to publish relative information in the grid information service and another framework to monitor grid resources using relative criteria.
