Grid Interoperability Solutions in Grid Resource Management

摘要

Since the management and beneficial utilization of highly dynamic grid resources cannot be handled by the users themselves, various grid resource management tools have been developed, supporting different grids. To ease the simultaneous utilization of different middleware systems, researchers need to revise current solutions. Grid Interoperability can be achieved at different levels of grid systems. In this paper, we investigate interoperability issues in Grid resource management, focusing on the following approaches: 1) extending existing resource brokers with multiple middleware support; 2) interfacing grid portals to different brokers and middleware; or 3) developing a new middleware component, a meta-broker that not only interfaces various brokers but also coordinates their simultaneous utilization. We show that all of these approaches contribute to enable Grid Interoperability, and conclude that meta-brokering is a significant step towards the final solution.
