Information federation in grid information services

摘要: Information Services address the challenging problems of announcing and discovering resources in Grids. Independent Grid projects have developed their own solutions to Services. These are not interoperable with each other, target vastly different systems diverse set requirements: Large-scale applications require management large amounts relatively slowly varying metadata. E-Science such as dynamic Grid/Web Service collections greater support for We research that both scalability metadata performance demands rapidly updated information regions. We propose a novel system architecture provides unification federation The proposed utilizes publish-subscribe paradigm associative shared memory platform provide an add-on interacts existing systems. present evaluation our approach investigate its practical usefulness. results demonstrate improves quality services terms fault-tolerance negligible processing overheads. also indicate efficient decentralized Architectures can be built by utilizing based messaging schemes.
