Computing at STAR

Torre Wenaus
 BNL, for the STAR Collaboration

Speaker: Torre Wenaus

  The Solenoidal Tracker At RHIC (STAR) is a large acceptance collider detector, commissioned at Brookhaven National Laboratory in 1999 and anticipating first physics running in spring 2000. STAR employs a 4m scale TPC and other detectors to measure the momentum and identify several thousand particles per event with the foremost physics objective being the discovery and characterization of the Quark Gluon Plasma. STAR has developed an offline software infrastructure designed to meet the near and long term needs of the STAR physics program. A component based framework built over the ROOT system supports both wrapped legacy Fortran simulation and reconstruction codes and STAR's fully C++/OO physics analysis code, and is used both for offline production and as a physics analysis environment. STAR's C++/OO event model used in all physics analysis software presents a purely transient, I/O independent interface to the user while the implementation directly employs ROOT I/O to provide efficient and maintainable I/O. Conditions, event store and production database facilities have been implemented using MySQL, STAR having ceased development of ODBMS-based databases. This paper will present a general overview of STAR computing with particular attention to progress with and lessons from our OO experience.
