Description

Building on several years of sucess with the MCRunjob projects at DZero and CMS, the fermilab sponsored joint Runjob project aims to provide a Workflow description language common to three experiments: DZero, CMS and CDF. This project will encapsulate the remote processing experiences of the three experiments in an extensible software architecture using web services as a communication medium. The core of the Runjob project will be the Shahkar software packages that provide services for describing jobs and targeting them at different execution environments. A common interface to multiple storage and compute grid elements will be provided, alllowing the three experiments to share hardware resources in a transparent manner. Several tools provided by Shahkar are discussed including FileMetaBrokers, hich provide a uniform way to handle files and metadata over a distributed cluster, the ShREEK runtime execution environment that allows executable jobs to provide a real time monitoring and control interface to any system, the scriptObject generic task encapsulation objects and XMLProcessor object persistency tool.
