云计算在BESIII数据处理与分析中的应用

为适应BESIII实验数据的积累和资源需求的大幅增长,论文从性能评估、软件部署、用户使用、资源调度、数据管理等五个关键问题对BESIII数据处理与分析利用云计算资源展开研究,并通过BESIII分布式计算系统对云计算资源的整合实现了BESIII作业在云资源上的弹性调度和成功运行,这将为今后大规模应用奠定基础。

Study of Cloud Application in BESIII Data Processing and Analysis

To meet the challenge of aggregation of BESIII experiment data and large increase of resource de-mands, the paper carried out studies on five key elements including virtualization performance, software deploy-ment, usage modes, elastic scheduling and data management in the BESIII cloud application. The implementa-tion based on BESIII distributed computing system has made BESIII jobs elastically scheduled and successfully run on Cloud, which are necessary steps for future large-scale applications.
