Supercomputers take science by storm
Date:7/28/2010

Five researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory will lead projects that have been awarded almost 200 million processor-hours of computing time at Argonne's Leadership Computing Facility (ALCF). The ALCF is home to an IBM Blue Gene/P, a supercomputer capable of performing 557 trillion calculations per second, enabling scientists and engineers to conduct cutting-edge research in weeks or months rather than years.

"By providing millions of hours of computing time on this powerful system, these awards allow us to address some of the nation's most challenging scientific problems," said Pete Beckman, director of ALCF.

Chosen through a peer review process, the following Argonne projects have been selected by DOE to run at the ALCF as part of the new ASCR Leadership Computing Challenge (ALCC).

  • Andrew Siegel, a computational scientist and leader of Argonne's nuclear simulation activities, was awarded 75 million hours to investigate vibrations caused by turbulent flow in the core of light-water reactors. Simulating these behaviors will help optimize reactor fuel use, as well as advance our understanding of computational fluid dynamics.

  • Micheal Smith, an Argonne nuclear engineer, was awarded 38 million hours for the analysis and design of sodium-cooled fast reactors. This research is crucial in the development of nuclear reactors that are safe, affordable and environmentally friendly. It also represents one of the most challenging multiphysics simulation problems, which requires coupling neutronics simulation together with thermo-fluid and structural analysis simulations.

  • Michael Borland of Argonne's Advanced Photon Source (APS) was awarded 36 million hours to optimize the configuration of magnets as part of a planned upgrade to the APS a world-class source of high-energy, tunable X-rays for scientific research. Borland will use an innovative genetic optimization techniqu
