摘要
给出了一种基于多级资源池的负载平衡算法,采用主控节点集中分配和后台节点自治调节相结合的策略。并针对多级网络结构的集群系统的优势提出了集群系统中局部优先负载平衡的策略来降低进程迁移的代价,有效地提高了并行作业的响应时间,提高了系统的资源利用率。
A load balancing algorithm was presented based on multilevel resource pool using master node to allocate task centrally and back nodes to self-adjust load. And local priority load balancing method was presented based on multilevel network architecture to reduce cost of process migration to effectively improve executive performance of parallel job and resource utilization ratio.
