摘　　要：高能物理实验规模不断扩大,计算和存储需求不断增长,即将建成的中国散裂中子源(Chinese Spallation Neutron Source,CSNS)对物理实验计算环境同样有较高要求。进入云计算时代,资源的灵活配置和集中管理不仅降低了硬件成本还大大提高了资源利用率。本文首先介绍了云计算技术的在高能物理实验中的应用现状,然后介绍中国科学院高能物理研究所东莞分部目前所建设的中国散裂中子源对于计算环境的的具体需求,接下来从基础运维、统一认证、存储系统、Open Stack、资源监控五个方面详细阐述了基于Open Stack的云计算环境的设计和实践,以及如何利用其实现对CSNS计算资源的弹性管理,最后对CSNS云计算环境的现状进行了总结并提出了对未来的展望。The requirements of computing and storage for High Energy physics experiments are growing rapidly with the expansion of the experiment scale, the Chinese Spallation Neutron Source （CSNS）,which is near completion, has also higher requirements for computing system. The new computing pattern, cloud computing, can make IT resources configuration flexible and management centralized. Under this computing environment, the cost of hardware can be reduced, furthermore, the resource utilization can be improved greatly. From the research and practice aspects, firstly, the application status of cloud computing in High Energy Physics Experiments is introduced in this paper. Secondly, the special requirements of CSNS, constructed by Institute of High Energy Physics, Chinese Academy of Sciences, are discussed further. Thirdly, the design and practice of cloud computing platform based on OpenStack and elastic management of computing resources are demonstrated mainly from the aspects of basic maintenance, unified authentication, storage system, OpenStack and resource monitoring. FinallY, some future prospects of CSNS cloud computing system are summarized.
