在正常的数据采集过程中，CMS预计可能支持多达2000名分析用户。自2008年初以来，已有800多人向CMS计算基础设施提交了远程分析工作。这些用户中的大部分将在40多个合作医疗服务二级中心得到支持。在一组全球分布的计算集群上支持全球分布的用户社区是一项需要重新考虑用户支持分析操作的正常方法的任务。2008年，CMS成立了一个分析支助工作队，为大规模的物理分析活动做准备。工作队的任务是评估现有的支持工具、用户支持技术和用户的直接反馈，目的是在利用分布式计算环境时提高成功率和用户体验。工作队确定了评估和减少通过网格界面提交的非零退出代码申请的数量所需的工具，并与CMS实验仪表板开发人员合作，以获得必要的信息，以便迅速和主动地查明不同站点托管的用户作业和数据集的问题。分析小组调查的结果被汇编。在各地理区域建立了测试和调试问题的参考平台。工作队还评估了向常设分析业务任务过渡所需的资源。在本报告中，将讨论工作队的结果以及开始数据采集的CMS分析业务计划。
During normal data taking CMS expects to support potentially as many as 2000 analysis users. Since the beginning of 2008 there have been more than 800 individuals who submitted a remote analysis job to the CMS computing infrastructure. The bulk of these users will be supported at the over 40 CMS Tier-2 centres. Supporting a globally distributed community of users on a globally distributed set of computing clusters is a task that requires reconsidering the normal methods of user support for Analysis Operations. In 2008 CMS formed an Analysis Support Task Force in preparation for large-scale physics analysis activities. The charge of the task force was to evaluate the available support tools, the user support techniques, and the direct feedback of users with the goal of improving the success rate and user experience when utilizing the distributed computing environment. The task force determined the tools needed to assess and reduce the number of non-zero exit code applications submitted through the grid interfaces and worked with the CMS experiment dashboard developers to obtain the necessary information to quickly and proactively identify issues with user jobs and data sets hosted at various sites. Results of the analysis group surveys were compiled. Reference platforms for testing and debugging problems were established in various geographic regions. The task force also assessed the resources needed to make the transition to a permanent Analysis Operations task. In this presentation the results of the task force will be discussed as well as the CMS Analysis Operations plans for the start of data taking.
