【摘要】 应用软件License是昂贵的计算资源,校园网格是分布、共享的应用环境,在该环境下研究License的管理有着重要的意义。本文提出了支持License管理策略的校园网格管理系统体系结构,提出了基于角色和等待时间的网格作业动态优先级计算方法,提出了基于资源稀缺性和负载的License预留策略及剥夺策略,并在此基础上提出了基于动态优先级和集群负载的网格资源调度算法PLS。提出的算法和策略在校园网格进行了部署和应用,证明了其可以提高资源利用率,实现不同等级用户服务的差异性,保证同等级用户之间的公平性。更多还原

【Abstract】 The commercial software licenses are very expensive. So it is important to study the licenses optimization management under the distributed sharing environment of campus grid. In this paper,a novel architecture of campus grid is proposed which supports policy-based license management. The algorithm for grid job priority is presented,which is based on roles and waiting times. The reservation and depriving policy is also proposed based on the clusters load and rare degree of licenses. The policies and algorithm have been used in the NPU campus grid. The results show that it improves the utilization rate of licenses,realizes the difference of QoS between the users with different roles,and ensures the fairness between the users with the same role.更多还原
