一种基于虚拟化技术的异构网格互操作机制研究与实现

Research and Implementation of Interoperability Between Heterogeneous Grids Based on Virtualization

针对目前网格系统在实现机制、技术支持上异构性大,缺乏互操作,提出一种基于虚拟化技术的异构网格互操作机制(Virtualization-based Grid Interoperation,VIGI).VIGI通过构建虚拟管理层和插件模块,实现异构网格互操作,同时保证各网格平台的独立性.GOS、CGSP是中国国家网格(CNGrid)和中国教育科研网格(ChinaGrid)两大异构网格支撑中间件.基于VIGI,实现了CNGrid和ChinaGrid互操作.实验验证虚拟化技术在异构网格互操作中的可行性和有效性.

There are great heterogeneities in current grid systems,which makes interoperation among these grids very complex.To address the issues,Virtualization-based Grid Interoperation（VIGI） is proposed in the paper.With virtualization and plug-in technologies,VIGI achieves the interoperability between heterogeneous grid platforms while keeping the independence of them.There are two well-established grid systems in China,ChinaGrid and China National Grid,and they are built with two different grid middlewares,CGSP and GOS.With VIGI,the interoperation implementation between these two grid systems,as a case study,become a reality.Finally,the experimental evaluation shows that VIGI is effective and efficient.
