【摘要】：高能物理计算是典型的高性能计算的应用,运行时需要大量的CPU资源。如果系统的CPU资源利用率不高,会使得计算效率大大下降。传统的高能物理计算环境资源管理是静态的,很难同时满足突发、批处理、CPU密集型、数据密集型等不同类型的作业对于不同的物理资源的需求。文中基于Openstack构建的虚拟计算集群系统,实现以CPU核为粒度进行调度作业,根据当前的作业和虚拟资源情况,动态调度资源,大大提高了资源的利用率。首先介绍本系统的相关研究工作,包括KVM虚拟机的测试优化、高能物理作业在虚拟机上的性能测试及高能物理公共服务云IHEPCloud,这些工作进一步表明了高能物理实验的数据分析在虚拟机上的性能是完全可以被接受的;然后详细介绍了虚拟计算集群系统的设计与实现;最后给出虚拟机计算集群在高能物理计算中的实际应用情况,证明了虚拟计算集群系统能很好地满足高能物理的计算需求。
[Abstract]:High energy physics calculation is the application of high performance computing of the typical operation, need a large number of CPU resources. If the CPU of the system resource utilization rate is not high, the calculation efficiency is greatly reduced. The traditional computing environment of high energy physics resource management is static, it is very difficult to meet the emergency, batch processing, CPU intensive operations, demand data intensive different types for different physical resources. The virtual cluster computing system based on Openstack in this paper, based on CPU kernel granularity scheduling, according to the work and the current situation of the virtual resource, dynamic resource scheduling, greatly improving the utilization rate of resources. First introduced the related research work of the system the test, including optimization of KVM virtual machine, high energy physics performance test on virtual machine and high energy physics public service cloud IHEPCloud, which further shows the reality of high energy physics Check the performance of data analysis in the virtual machine is perfectly acceptable; and then introduces the design and implementation of virtual computing cluster system; calculation of practical application of cluster computing in high energy physics virtual machine finally, proves that the virtual cluster system can well meet the requirements of high energy physics calculation.
