CMS协作依赖于位于大型大学和国家实验室的7个全球分布的一级计算中心，用于CMS原始数据的第二保管副本和模拟数据的主要副本，向二级中心提供数据服务能力以供分析，以及实验中的大部分再处理和事件选择能力。一级站点在CMS中具有挑战性的作用，因为它们预计将从CERN和区域二级中心摄取和存档数据，而它们将数据以与CERN原始输出数据速率相当的速率输出到全球二级网络。一级中心的综合能力是欧洲核子研究组织资源的两倍多，有效利用这一庞大的分布式资源是一项挑战。在这篇文章中，我们将讨论经验建设，运营和利用CMS Tier-1计算中心。我们将总结Tier-1的设施挑战，包括CMS服务的稳定运行，扩展到大量处理请求和大量数据的能力，以及提供托管存储和高性能数据服务的能力。我们还将介绍远程使用分布式Tier-1中心的操作经验：传输数据、提交数据服务请求和提交批处理请求。
The CMS Collaboration relies on 7 globally distributed Tier-1 computing centres located at large universities and national laboratories for a second custodial copy of the CMS RAW data and primary copy of the simulated data, data serving capacity to Tier-2 centres for analysis, and the bulk of the reprocessing and event selection capacity in the experiment. The Tier-1 sites have a challenging role in CMS because they are expected to ingest and archive data from both CERN and regional Tier-2 centres, while they export data to a global mesh of Tier-2s at rates comparable to the raw export data rate from CERN. The combined capacity of the Tier-1 centres is more than twice the resources located at CERN and efficiently utilizing this large distributed resources represents a challenge. In this article we will discuss the experience building, operating, and utilizing the CMS Tier-1 computing centres. We will summarize the facility challenges at the Tier-1s including the stable operations of CMS services, the ability to scale to large numbers of processing requests and large volumes of data, and the ability to provide custodial storage and high performance data serving. We will also present the operations experience utilizing the distributed Tier-1 centres from a distance: transferring data, submitting data serving requests, and submitting batch processing requests.
