支持e-Science的网格体系结构及原型研究

摘要

This paper presents an e-Science Grid architecture called Virtual and Dynamic Hierarchical Architecture (VDHA). VDHA is a decentralized architecture with some P2P properties. It also has scalable,autonomous, exact, and full service discovery properties. We have implemented a demonstration VDHA_based Grid prototype - VDHA_Grid, which has scalable Grid information service. VDHA_Grid is the core software for the project of the Chinese University e-Science Grid. In this paper, advantages and several protocols of the VDHA are also discussed.%提出了e-Science网格的虚拟动态分层体系结构(VDHA).VDHA是具有P2P特征的分散的支持e-Science网格的体系结构.VDHA具有可扩展性、自动性、精确和完全服务发现的特点.实现了基于VDHA的验证原型系统VDHA Grid,其具有可扩展的网格信息服务.VDHA_Grid是中国大学e-Science网格项目的核心软件.也讨论了VDHA的一些优点及相关协议.
