Description
The ATLAS experiment recently entered the data taking phase, with the
focus shifting from software development to validation.
The ATLAS software has to be both robust to process large datasets and
produce the high quality output needed for the experiment scientific
exploitation. The validation process is discussed in this talk,
starting from the validation of the nightly builds and pre-releases to
the final validation of software releases used for data taking and
scientific results.
A few thousands events are processed every day using the most recent
nightly build and physics and technical histograms are processed
automatically. New versions of the software are released every 3 weeks
and are validated using a set of 100K events that are monitored by
people appointed by each of the ATLAS subsystems. Patch version of the
software can be deployed at the ATLAS Tier0 and on the grid within a
12-24 hours cycle and a crew of validation shifters continuously
monitor bug reports that are submitted by the operation teams.
