摘要
分析了高校CSCL系统在资源共享方面存在的资源利用率低、孤岛资源和服务器瓶颈等问题及其产生的原因,提出将网格技术引入高校CSCL系统的思路,设计了一个具有资源层、网格中间件层、网格服务层和应用层等四层结构的基于网格的校园CSCL资源共享平台,并研究了资源管理、任务调度等关键技术,对所构建的资源共享平台的优势进行了分析。
At first this paper analyzes the reasons of low resource utilization rate,resource island,sever bottlenecks and some other issues,then puts forward the idea of introducing grid into college CSCL system.A college CSCL resource sharing platform based on grid is designed,which has four resource layer such as grid middleware layer,grid service layer and application layer.Meanwhile it studies resource management,task scheduling,and other key technologies,finally makes analysis of advantages of the resource sharing platform proposed.
