基于虚拟组织的网格文件资源共享模型

网格计算主要关注大规模的资源共享,且这种共享是高度可控的。为解决网格环境下文件资源共享与管理的问题,提出了一个网格文件资源共享模型FsvGrid。该模型引入注册通知机制,并采用确定性算法与非确定性算法相结合的消息传递机制,使得网格中的各个节点之间能够高效协作;采用分层结构,屏蔽了文件资源的多样性;增加了共享的安全性,可以对共享进行控制;提出了一种依靠虚拟组织来对文件资源进行管理的方式,解决分布式资源难以管理的问题。

Grid File Sharing Model Based on Virtual Organizations

Grid computing focuses on large-scale resource sharing,and this sharing is highly controlled.In order to solve the resource sharing and managing problem,a grid file sharing model is proposed in this article.This model has the following features:having register-notification mechanism and high performance message passing mechanism with both fix and randomized algorithms to ensure the nodes in the grid can well cooperate with each other;using layered structure to hide the heterogeneous resources;improving security and being able to control the sharing;proposing a file managing mechanism based on virtual organizations so as to manage distributed resource.
