The DOE’s Leadership Computing Facilities at Argonne and Oak Ridge national laboratories have awarded a combined 4.7 billion supercomputing core hours to 61 science and engineering projects through its 2013 Innovative and Novel Computational Impact on Theory and Experiment program. The ALCF awarded 2.83 billion hours on Mira and Intrepid, both IBM Blue Gene systems. When INCITE made its first awards in 2004, three projects received an aggregate 5 million hours on DOE supercomputers. The collective 2013 allocation represents an almost 1,000-fold growth in resources provided to researchers. To date, INCITE has delivered more than 10 billion computing hours to the scientific community.
