| 摘 要： | 作业调度是要实现作业和资源的最佳匹配,协调对资源的征用矛盾.软件环境和硬件资源对作业运行都有影响,实验证明硬件资源对作业的影响很大,据此提出了基于资源域的分级调度模型,提供全局和局部两种调度方式.节点根据配置划分成不同的资源域,调度时根据作业类型匹配最佳的资源域,该模型有效利用了集群资源,减轻了Server的负担,并能提高系统的可扩展性.在全局调度中,还提供了预约机制调度高优先级作业.

| Abstract: | Jobs and resources are a perfect match is the task of job scheduling.Scheduling is to mediate the conflict of resource.Software and hardware all have influence on jobs.Tests prove that hardware resources have large influence on jobs.Then hierarchy scheduling model based on resource domain is brought forward Which divides nodes into several resource domains and matches the job with best re- source domain.Local scheduling and global scheduling are provided.The model lightens the burden of server.It highly improves the utilization and scalability of the system.Booking is used for high priority jobs in global scheduling. |
