Description

for the BaBar Computing Group. The analysis of the BaBar experiment requires many times the measured data to be produced in simulation. This requirement has resulted in one of the largest distributed computing projects ever completed. The latest round of simulation for BaBar started in early 2003, and completed in early 2004, and encompassed over 1 million jobs, and over 2.2 billion events. By the end of the production cycle over 2 dozen different computing centers and nearly 1.5 thousand cpus were in constant use in North America and Europe. The whole effort was managed from a central database at SLAC, with real-time updates of the status of all jobs. Utilities were developed to tie together production with many different batch systems, and with different needs for security. The produced data was automatically transfered to SLAC for use and distribution to analysis sites. The system developed to manage this effort was a combination of web and database applications, and command line utilities. The technologies used to complete this effort along with its complete scope will be presented.
