Development platform for HEP cloud services

云计算日益成为高能物理（HEP）大量计算需求实验的重要资源。维多利亚大学的HEP计算小组正在ATLAS和Belle II实验中使用云。我们利用欧洲和北美的云构建了一个分布式系统。此外，我们正在帮助管理ATLAS高级别触发器（HLT）的资源，该触发器在无碰撞光束期间作为计算云运行。我们的团队得到了CFI和NSERC的资助，为数据密集型HEP应用扩展分布式云计算系统的功能。此外，我们正在为Belle II加拿大数据中心准备CFI，以便在基于云的系统上存储和处理加拿大的原始数据。本提案中要求的资金将为我们的项目提供开发和测试平台的关键服务器。该项目的结果将对ATLAS和Belle II实验有长期的好处，并为高素质的人员提供一个极好的训练场地。

Cloud computing is increasingly becoming an important resource for high-energy physics (HEP) experiments with large computing requirements. The HEP computing group at the University of Victoria is leading the effort to use clouds in the ATLAS and Belle II experiments. We have constructed a distributed system using clouds in Europe and North America. In addition, we are helping to manage the resources of the ATLAS High-Level Trigger (HLT), which is operated as a compute cloud during periods of no colliding beams. Our group has been funded by CFI and NSERC to expand the functionality of the distributed cloud computing system for data-intensive HEP applications. In addition, we are preparing a CFI for a Belle II Canadian Data Centre for storing and processing the raw data in Canada on a cloud-based system. The funds requested in this proposal will provide critical servers for a development and test platform for our projects. The outcome of the project will have long term benefit for the ATLAS and Belle II experiments, as well as provide an excellent training ground for highly qualified personnel.
