The BABAR Tier-A site at GridKa — •Enrico Feltresi, Andreas Petzold, Jan Erik Sundermann, Heiko Lacker, and Bernhard Spaan — Technische Universität Dresden, Dresden, Germany

The BABAR experiment at the Stanford Linear Accelerator Center is taking data since 1999. The high volume of data and simulated events requires computing resources distributed among a few high perfomance computing centers, so called Tier-A sites.The Grid Computing Center, GridKa, at Forschungszentrum Karlsruhe serves as the German BABAR Tier-A site since november 2002. It offers computing resources for physics analysis, simulation production and for data preselection (skimming), which will dominate the BABAR activities at GridKa in 2004. Beyond that, GridKa will be the future German Grid competence center for BABAR and other experiments, e.g. the LHC experiments. Currently, we evaluate several Grid middleware tools for a distributed BABAR computing framework, focusing on the LHC Computing Grid Project (LCG) and on the ALIce ENvironment (AliEn).The BABAR computing environment and corresponding grid efforts related to GridKa will be discussed.
