Abstract

The CMS experiment will produce a large amount of data (few PBytes each year) that will be distributed over many computing centres spread in the countries participating to the CMS collaboration. To access and analyse data available at remote sites, physicists will use the grid infrastructure. CMS is developing a user friendly tool, CRAB (Cms Remote Analysis Builder), whose aim is to simplify the creation and the submission of analysis jobs into the grid environment. Its purpose is to hide the grid infrastructure complexity to final users, so that they can access remote data as easily as in a local environment. Data discovery, resources availability, status monitoring and output retrieval of submitted jobs are fully handled by CRAB. In this report we will explain how CRAB is interfaced with other CMS/grid services, the experience gained during production and future developments
