网格计算研究越来越多,但是当前的研究多数面向基层基础构架的研究,如Globus,Legion等,也有在此基础上的一些应用研究,如计算网格、信息网格、知识网格和商业应用网格等,而对于网格中间件GM的研究还是处于启蒙阶段。文中在讨论了网格和中间件技术后,将两者很好地结合,给出一种网格中间件的体系结构,旨在实现当前基于开放式网格服务架构(OGSA)标准下的网格服务聚合和工作流思想。
It exists much more researches on gird computing, but most of them are oriented with the reaearch of infrastructure, such as Globus, Legion and so on. There are also some application researches, which are computing grid, information grid, knowledge grid and business grid. The research on gird middleware is still on the stage of enlightenment. After discussing the technologies about gird and middleware, try to merge them best and put forward an architecture of grid middleware. Its main functiotts contains grid service convergence and workflow based on OGSA(open grid service architecture).
