The efficient exploitation of worldwide distributed storage and computing resources available in the grids require a robust, transparent and fast deployment of experiment specific software. The approach followed by the CMS experiment at CERN in order to enable Monte-Carlo simulations, data analysis and software development in an international collaboration is presented. The current status and future improvement plans are described.
Recently SCRAM (Software Configuration And Management) has been adopted by the applications area of the LHC computing grid project as baseline configuration management and build support infrastructure tool. SCRAM is a software engineering tool, that supports the configuration management and management processes for software development. It resolves the issues of configuration definition, assembly break-down, build, project organization, run-time environment, installation, distribution, deployment, and source code distribution. It was designed with a focus on supporting a distributed, multi-project development work-model. We will describe the underlying technology, and the solutions SCRAM offers to the above software engineering processes, while taking a users view of the system under configuration management.
