Description
There is a need for a large dataset of simulated events for use in
analysis of the data from the BaBar high energy physics experiment.
The largest cycle of this production in the history of the experiment
was just completed in the past year, simulating events against all
detector conditions in the history of the experiment, resulting in over
eleven billion events in eighteen months. This computing effort was
distributed to almost twenty different computing centers in North
America and Europe. The history of this production will be discussed
in the talk. This was the second cycle of production for BaBar to
produce data as a set of root files, where at the start of the
experiment data produced into Objectivity databases. But even though
Objectivity was removed from use in data storage, it was still in use
for detector conditions. For the next cycle of production, which has
recently begun in the experiment, the use of an Objectivity database
for the detector conditions was removed, and condition data was
distributed with the jobs as a set of root files. The results of this
latest stage in the development of simulation production in BaBar will
be discussed, and its effect on the computing effort.
