网格资源共享环境的构建

随着网格应用的发展 ,用户对资源共享的需求不断增加 ,而网格环境中资源的特点却制约着资源共享的实现。本文主要探讨构建一个基于用户特性的资源共享环境的基本问题。以用户为中心 ,根据共享资源的需求与消费 ,利用资源调度者协调供求关系 ,使资源消费者与供应者之间形成激励机制 ,最终达到供求平衡 ,可以有效地促进用户共享自身可用资源 ,最大范围地扩展网格的应用空间。

With the development of the application of grid,the users' demand for resource s haring is on the increase.However,the characteristics of resources in the grid e nvironment restrict the realization of resource sharing.This paper mainly discu s ses some basic issues related to constructing a resource sharing environment bas ed on user properties,which is user-centered and relies on resource dispat chers to coordinate the relationship between supply and demand in accordance wit h the resource demand and consumption so as to form a stimulating mechanism betw een resource consumer and provider and to finally reach a balance between supply and demand.This mechanism can effectively promote the users to share their own reources and expand the application space of grid to the greatest extent.
