Use of the European Data Grid software in the framework of the BaBar distributed computing model

We present an evaluation of the European Data Grid software in the framework of the BaBar experiment. Two kinds of applications have been considered: first, a typical data analysis on real data producing physics n-tuples, and second, a distributed Monte-Carlo production on a computational grid. Both applications will be crucial in a near future in order to make an optimal use of the distributed computing resources available throughout the collaboration. In both cases we have been able to setup a realistic environment demonstrating that both applications can be run on Grid. We conclude that all the necessary functionalities are present but some scalability issues remain. In the near future we intend to test the Virtual Data Toolkit (VDT) in the BaBar environment and to explore the inter-operability between European and US Grid implementations. (authors)
