网格记账系统研究与实现

An OGSA-based Grid Accounting System

该文主要介绍了基于开放网格服务体系结构(OGSA)的山东大学网格记账系统-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。该文将重点介绍SDUGAS的体系结构、实现的基本原理和方法、资源消费信息的采集过程、资源的价格策略以及网格银行的设计与实现等内容．并且在最后给出了一个SDUGAS记账和计费过程的简单实例。

This paper presented an Open Grid Services Architecture (OGSA)-based accounting system known as Shandong University Grid (SDUGRID). It was developed with an emphasis on a consistent data model and easy integration into existing scheduling at a few independent campus clusters. This paper introduced the basic implementing mechanism of SDUGAS architecture, collecting process of resources usage information, resource price policy and gridbank etc. Finally, an example of a simple task run on the SDUGAS was provided to illustrate the process of accounting and charging.
