A visualization of a simulated collision event in the ATLAS detector. This simulation, containing a Z boson and five hadronic jets, is an example of an event that is too complex to be simulated in bulk using ordinary PC-based computing grids.

We are presently involved in the following activities:

  • Event data and metadata management for the ATLAS experiment.
  • Simulated event data for the ATLAS experiment
  • Simulating the interaction of particles in the Fermilab mu2e and g-2 experiments.
  • Theoretical calculations of vector boson plus multijet production at the LHC

We do this using computers on the Worldwide LHC Computing Grid, the Blue Gene/Q system at the Argonne Leadership Computing Facility, the Cray supercomputers at NERSC, and elsewhere.
