针对传统的集群计算资源无法满足高能物理计算中对于海量数据处理的需求,基于桌面网格技术提出一种新型高能物理计算系统。该系统通过虚拟化技术,实现高能物理计算在桌面网格上的应用部署,并且设计镜像元数据服务进行远程镜像库管理。根据高能物理计算的特点,实现以DIRAC,BOINC,3G-bridge为基础的新型桌面高能物理计算系统。系统以BOINC计算服务为基本框架,3G-bridge处理作业请求,DIRAC提交计算作业。测试与分析结果表明,该系统能对高能物理作业提供稳定高效的计算服务,计算结果可靠,具有高可扩展性。
In view of the traditional cluster computing resources can not meet the high-energy physics computing requirements for mass data processing, a new type of high-energy physics computing system based on desktop grid technology is proposed. The system realizes the application deployment of high-energy physics computing on the desktop grid through virtualization technology, and designs the mirror metadata service for remote mirror library management. According to the characteristics of high-energy physics computing, the new desktop high energy physics computing system based on DIRAC, BOINC and 3G-bridge is realized. System to BOINC computing services as the basic framework, 3G-bridge handle job requests, DIRAC submitted computing jobs. The test and analysis results show that the system can provide stable and efficient computing services for high-energy physics operations with reliable calculation results and high scalability.
