The Enrico Fermi Institute at the University of Chicago, partnering with Indiana University, has a computing facility for physics working on the ATLAS experiment at the LHC. The Midwest Tier-2 Center (MWT2) began in 2005 and now consists of 18 racks of computing and storage servers connected via a 10 Gbps network to a world-wide computing grid for the LHC computing project. Approximately 4000 jobs can be run on the facility accessing over 1.5 Petabytes of locally stored data. The MWT2 is a leading data center among international Tier 1 facilities in terms of CPU, storage and network capacity, and has served over 600 ATLAS physicists since LHC operations restarted in 2010.
