基于OGSA的网格计费系统

An OGSA-based Accounting System for Campus Grid

介绍了基于开放网格服务体系结构(OGSA)的山东大学网格计费系统-—SDUGAS,该系统主要致力于解决网格环境下异构资源使用的记账和计费问题,为用户和管理员提供良好的网格服务,在此基础上大力提高网格资源的利用率。山东大学网格计费系统的设计和实现以OGSA为标准,充分考虑了网格环境下系统的可扩展性和可移植性,强调在网格环境下数据描述的一致性和系统集成安装的易操作性。介绍了SDUGAS的体系结构、实现的基本原理和方法、资源信息的采集过程、资源预订、资源的价格策略以及网格银行的设计与实现等内容,给出了一个SDUGAS记账和计费过程的简单实例。

This paper presents an open grid services architecture（OGSA）-based accounting system known as Shandong University grid （SDUGRID）.
