摘要： 由于网格节点具有很高的自治性,节点间是一种基于P2P的关系,此外,网格系统中节点数目一般比较大,因此现有的网格资源调度系统普遍地存在可扩展性差的问题,其性能随着节点数目的增加而急剧下降。文章提出了一种基于虚拟资源池的网格资源调度体系,较好地处理了网格系统中节点的平等性和自治性、节点数目的巨大性以及计算资源和数据资源的协同调度等问题。

Abstract: In a grid system, each node is autonomic and the relation between every two nodes is P2P-based, in addition, the number of a gridsystem will be very large. These lead to poor scalability in much of the current grid scheduling systems and with the increase of nodes, theirperformance deteriorate. This paper presents the architecture of resource scheduling for SDG and it deals with the P2P-based relations between everytwo nodes, the magnitude of node’s number and the collaboratively scheduling of computing resource and data resource.
