2015年,CMS将以前所未有的速度和复杂性开启收集LHC碰撞的新时代。这将给我们的计算系统带来巨大的压力。由于资源需求大幅增加,0级基础设施对原始数据的即时处理将不再仅限于CERN。在LHC运行2中,我们需要将其作为分布式系统运行,同时利用CERN基于云的敏捷基础设施和CMS Tier-1网格资源的重要部分。在LHC Run 2的另一个重大变化中,我们将使用多线程框架处理所有数据,以处理增加的事件复杂性并确保资源的有效利用。这篇文章将涵盖Tier-0基础设施的发展,并介绍2015年首次数据采集的规模测试结果和经验。
In 2015, CMS will embark on a new era of collecting LHC collisions at unprecedented rates and complexity. This will put a tremendous stress on our computing systems. Prompt Processing of the raw data by the Tier-0 infrastructure will no longer be constrained to CERN alone due to the significantly increased resource requirements. In LHC Run 2, we will need to operate it as a distributed system utilizing both the CERN Cloud-based Agile Infrastructure and a significant fraction of the CMS Tier-1 Grid resources. In another big change for LHC Run 2, we will process all data using the multi-threaded framework to deal with the increased event complexity and to ensure efficient use of the resources. This contribution will cover the evolution of the Tier-0 infrastructure and present scale testing results and experiences from the first data taking in 2015.
