Description

The Babar experiment has been running at the SLAC National Accelerator Laboratory for the past nine years, and has measured 500 fb-1 of data. The final data run for the experiment finished in April 2008. Once the data was finished the final processing of all Babar data was started. This was the largest computing production effort in the history of Babar, including a reprocessing of all measured data, a full simulation with latest code versions for all measured detector conditions, and a full skimming of this data into all current analysis streams for use. This effort ended up producing the largest rates of CPU use and data production in the history of an already large scale experiment. The difficulties and successes of this effort will be reported with the amounts of data size, cpu time, and computing centers used.

Summary

Production of the final Babar data set, summary of effort and computing use.
