MRI/RUI: Development of a Computing Cluster to Support the University of Richmond Nuclear Physics Research Program at Jefferson Lab

正在开发一个计算机集群，以支持托马斯·杰斐逊国家加速器设施(杰斐逊实验室)的里士满大学(UR)电磁核物理研究计划。该系统将由50个从节点、一个主节点和一个3 TB的RAID文件服务器组成。每个从计算节点将有两个1-GHz Pentium III处理器、512MB的RAM和一个20G的硬盘。这些计算机将运行Linux操作系统，并将通过高速交换机配置在局域网上。主节点将用于管理批处理作业的执行，并充当防火墙以限制对系统的访问并减少集群节点之间的网络流量。该集群仿照UR开发的原型系统，并在过去两年中成功运行。该系统将用于杰斐逊实验室B厅的CEBAF大接受光谱仪(CLAS)合作的数据分析和蒙特卡洛模拟。CLAS研究计划的目标是研究重子和介子的结构和光谱，胶子自由度，以及原子核中的多核子关联。

A computer cluster is being developed to support the University of Richmond (UR) research program in electromagnetic nuclear physics at the Thomas Jefferson National Accelerator Facility (Jefferson Lab).The system will consist of 50 slave nodes, a master node, and a 3-TByte RAID file server. Each of the slave computing nodes will have two 1-GHz Pentium III processors, 512 MBytes of RAM, and a 20-GByte hard disk. The computers will run the Linux operating system and will be configured on a local area network through a high-speed switch. The master node will be used to manage the execution of batch jobs and to act as a firewall to restrict access to the system and reduce network traffic among the nodes of the cluster. The cluster is modeled after a prototype system that was developed at UR and has been running successfully for the past two years. The system will be used for data analysis and Monte-Carlo simulations for the CEBAF Large Acceptance Spectrometer (CLAS) Collaboration in Hall B at Jefferson Lab. The goal of the CLASresearch program is to study baryon and meson structure and spectroscopy, gluonic degrees of freedom, and multinucleon correlations in nuclei.
