基于虚拟化集群的核设计平台作业调度系统研究与实现

Research and Implementation of Nuclear Design Platform Job Scheduling System Based Virtualization and Cluster

针对核设计平台的运算效率不高、因硬件故障导致的运算中断,提出利用VMware对服务器进行虚拟化,建立虚拟化集群,采用LSF(Load Sharing Facility)平台对集群中的系统资源进行调度,实现核设计平台的高可用性和负载均衡。论文详细介绍了传统核设计平台在软硬件平台限制和资源利用率上的不足,设计了面向核设计平台的虚拟化集群作业调度系统,并将核设计软件包成功运行在该系统上。实验结果表明保证计算结果正确的前提下,运算效率呈倍数提高。

In order to improve the computational efficiency of nuclear design platform and eliminate interruption due to hardware failure,servers are virtualized using VMware,a virtual cluster is built,system resource in the cluster using LSF（Load Sharing Facility）platform is scheduled,the high availability and load balancing of the nuclear design platform are guaranteed.The software and hardware constraints of traditional nuclear design platform and the insufficience rate on resource utilization are introduced,the nuclear design platform job scheduling system is built based on virtualization and cluster,and the nuclear design software packages run in this system is made successfully.The test results indicated that the computational efficiency was multiply improved in new platform.
