CMS生产中的虚拟数据
Virtual Data in CMS Production
摘要：
GriPhyN嵌合体虚拟数据系统的初步应用已经在CMS生产蒙特卡罗模拟数据的背景下进行。GriPhyN Chimera系统由四个主要组件组成：1）虚拟数据语言，其用于描述虚拟数据产品，2）虚拟数据目录，其用于存储虚拟数据录入，3）抽象规划器，其解析特定虚拟数据产品的所有依赖性并形成位置和存在独立的规划，4）具体规划器，其映射抽象，逻辑计划到具体的、物理的网格资源上，这些网格资源负责暂存入/出文件并将结果发布到副本位置服务。CMS工作流规划器MCRunJob用于使用虚拟数据语言生成虚拟数据产品。随后，一个原型工作流管理器，称为WorkRunner，用于调度虚拟数据产品的实例化跨越网格。
英文摘要：
Initial applications of the GriPhyN Chimera Virtual Data System have been performed within the context of CMS Production of Monte Carlo Simulated Data. The GriPhyN Chimera system consists of four primary components: 1) a Virtual Data Language, which is used to describe virtual data products, 2) a Virtual Data Catalog, which is used to store virtual data entries, 3) an Abstract Planner, which resolves all dependencies of a particular virtual data product and forms a location and existence independent plan, 4) a Concrete Planner, which maps an abstract, logical plan onto concrete, physical grid resources accounting for staging in/out files and publishing results to a replica location service. A CMS Workflow Planner, MCRunJob, is used to generate virtual data products using the Virtual Data Language. Subsequently, a prototype workflow manager, known as WorkRunner, is used to schedule the instantiation of virtual data products across a grid.
