面向服务的网格资源管理模型研究

开放网格服务体系结构（OGSA）的出现表明让网格资源以服务形式提供标准化的接口已成为趋势，以前的资源管理模式已经不能满足应用的要求。为此，提出了一种面向服务的作业管理机制，它为用户提供透明的、与资源物理位置无关的并带有会话支持的作业服务接口，还引入了服务分级的概念来表示用户需求的不同网格服务级别，作业管理系统则根据可定制的服务级别，将各项QoS特性映射到具体的作业管理行为。最后以电子政务为例，初步构建了该模型的原形系统。

Service-Oriented Resource Management Model for Grid Computing

The emergence of OGSA represents a consensus on the standardization of resource accessing interfaces as grid services. However, current job management systems do not meet the application requirements from a service grid. In such paper, a service-oriented job management model is presented that provides a set of transparent and location independent interfaces. Service level is also introduced to differentiate QoS requirements. At last, an E-government prototype system is built according to our model.
