网格用户管理体系结构的研究与设计

Study and Design of Grid User Management Architecture

在网格系统的研究中 ,相对于资源 (客体 )管理而言 ,对网格用户 (主体 )管理的研究相对薄弱 网格用户的表示、命名以及网格用户管理的功能及体系结构的确定对实现一个实用的网格用户管理系统非常重要 首先论述了网格用户管理的特点、范围及内容 ,提出了网格用户的表示及命名方法 ,描述了网格用户的全生命周期状态图 在此基础上提出了一个网格用户管理体系结构 ,并实现了一个实用系统VegaGUS 最后给出了该实用系统的性能指标及评价 。

In the study of grid systems, the study of grid user(subject) management is relatively weak compared to that of the resource(object) management.Grid user expression, naming, the function and architecture of grid user management are very important for realizing an practical grid user management system.First the grid user management's feature, scope and content are discussed, the expression and naming method of grid user are presented, and the whole life cycle state chart of grid user is described.Then a kind of architecture of grid user management is presented and a practical system—VegaGUS is realized.Finally the performance index and evaluation of this system are discussed.The system solves the key problems of the grid user management.
