Argonne is the central site for work on database and data management. The group has key responsibilities in the design and implementation of the I/O model which must provided distributed access to many petabytes of data for both event reconstruction and physics analysis.

The group deployed a number of HEP packages on the BlueGene/Q supercomputer of the Argonne Leadership Computing Facility,  and currently generates CPU-intensive Monte Carlo event samples for ATLAS. Also, the group contributes to the HEP community by creating Monte Carlo samples for the HepSim public repository maintained by the ATLAS group.
