面向网格的协作式网络计算平台

A Grid-Oriented Collaborative Network Computing Platform

互联网资源的利用率无论在时间上 ,还是空间上都存在极度的不均 .在不干扰用户工作的前提下 ,充分利用互联网上闲置的资源 ,解决大规模的科学计算 ,具有极其重要的意义 .文章在前期HowU网格平台的网络计算组件的基础上 ,结合当前流行的网格技术和P2P技术 ,提出了一种协作式的网络计算平台 ,支持包括集群和单机两种类型的资源管理器和注册资源 ,通过资源管理器之间的协作和资源共享 ,实现了全球空闲资源管理的容错和负载平衡 .该文提出了两种简单实用的协作式算法 :空闲管理器申请应用算法以及过载管理器申请资源算法 。

There exists much load unbalance of Internet resources. It is significant to fully use spare resources on Internet to solve large-scale science computing issues, not disturbing the resource owner’s work. Based on grid and P2P technology, a collaborative network computing platform is proposed in this paper. Based on the collaboration and resource sharing among resource managers, the properties of fault tolerance and load balance are realized for the global resource management in this collaborative network computing platform. Two simple collaborative algorithms, one is about idle manager applying for application, and the other is about overloaded manager applying for resources, are proposed in this paper. Finally the performance analysis is given.
