面向多集群对等调度的网格系统研究与设计

Research and Design of P2P Scheduling Grid System for Multi-cluster

针对目前集中式调度的校园网格系统难以具备必要的可扩展性和容错性问题,利用对等模式进行多集群间网格作业调度。不仅增强网格系统的可扩展性和容错能力,而且使每个集群成为自主调度单元,通过彼此协作共同完成作业。系统将Globus网格中间件系统和OpenPBS调度系统有机的结合起来,通过增加辅助的调度服务,使网格作业在多个集群间迁移并且有效缓解单个集群的作业负担。

To settle the problem of deficient scalability and fault-tolerant capability of current centralized-scheduling campus grid system,a P2P model which was used to schedule the jobs among the multi-cluster was proposed.Scalability and fault-tolerance was not only enhanced for the grid system by this way,but also each cluster was turned into an autonomous scheduling unit and jobs were completed with cooperation among multi-cluster.The Globus grid middleware and the Open PBS were integrated by the system,which en...
