PILOT PRODUCTION GRID INFRASTRUCTURE FOR HIGH ENERGY PHYSICS APPLICATIONS

Current Data Grid tools are enhancing and getting more mature. On the other hand, several application users express their needs and requirements to deploy Grid tools in their daily work. Thus, there is a strong need that Grid tools make the transition from prototype tools to production tools. We have made several improvements and additions to an early release of the European DataGrid software tools in order to meet the requirements of data intensive sciences. We show that our software release is stable and performs well in order to be used in an international production infrastructure for physics data simulation with one High Energy Physics experiment. Furthermore, we outline the experience with interoperability solutions from the Grid Laboratory Uniform Environment (GLUE) activity.
