一个基于网格资源超市的计算网格资源管理模型

A Model of Resource Allocation and Management in Grid Computing Based on Grid Resource Supermarket

在现有的基于经济模型的网格资源管理方法中,用户共享资源访问一般经由网格用户代理实现,而资源提供者将资源交给网格资源代理处理,网格用户代理通过网格资源经纪访问网格资源代理,获取共享资源信息并使用共享资源。这类方法制约了用户直接选择使用共享资源,也限制了用户共享资源的范围、延长了作业运行周期。文章给出的基于网格资源超市的计算网格资源管理模型、共享资源访问流程及网格资源管理分配策略,较好地解决了这几个问题。

The current methods of the grid resource management based on the market or economic models employ the grid user agents to achieve the user resource sharing, the grid resource agents to manage the resources for the owners, the grid resource brokers to coordinate the grid user agents and the grid resource agents. However, these methods constrain the users on the selection and the range of the sharing resources and increase the processing time. This paper presents another grid resource management model based on the grid resource supermarket to resolve these problems. A program and a scheduling mechanism for the model are given.
