摘　　要：高能物理实验具有大数据量和高计算量的特点,需要分布式计算系统对多个合作单位的计算和存储资源进行整合。中国科学院高能物理研究所已经创建了分布式计算环境,并实现对多个高能物理实验的稳定支持。近年来由于云计算技术不断发展成熟,其扩展性和易定制的特性非常适合应用于高能物理实验计算,是一种新的分布式计算资源类型。我们对云计算与分布式计算的结合应用进行了研究,成功将云计算整合到中国科学院高能物理研究所的分布式计算系统中,实现云站点的稳定运行,并进入生产状态提供给物理用户使用。Experiment of high energy physics often produces huge amount of data and requires massive computations, thus it needs distributed computing system to integrate computing and storage resources from various collaborating institutes. A distributed computing system has already been setup in the Institute of High Energy Physics （IHEP）, Chinese Academy of Sciences in order to support multiple HEP experiments. Cloud computing has been developed rapidly in the past years. The scalability and customization features of cloud computing are suitable for HEP experiment computing, and it could be a new resource type for distributed computing. We studied the combination of cloud computing and distributed computing, and successfully integrated cloud computing into the distributed computing system in IHER At present, the cloud sites are operating stably and provided services to the physics users.
