Argonne scientists awarded supercomputing time to enable scientific breakthroughs
Date:12/1/2010

, with detailed technical descriptions, is available online on the Advanced Scientific Computing Research website.

Paul Fischer, a senior computational scientist, was awarded 25 million hours on the Intrepid to conduct simulation and analysis of advanced nuclear reactor designs. "Advanced simulation is a critical component in bringing advanced reactor technology to fruition in an economic and timely manner," said Fischer.

As part of Argonne's Simulation-Based High-Efficiency Advanced Reactor Prototyping (SHARP) project, Fischer and his team are studying open questions concerning the thermal-hydraulic performance of several components in next-generation reactors. Thermal-hydraulic performance issues figure prominently in understanding how to design safe and efficient reactors; they include coolant mixing, pumping requirements and natural circulation, under a variety of operating conditions.

Andrew Binkowski, a structural biologist, leads an Argonne team in applying the most advanced methods in biomolecular simulations and analysis to further our understanding of human health and disease. "A major obstacle to accurate biomolecular modeling is the number of approximations necessary to make the runtime feasible," said Binkowski. "The vast computing resources now remove some of these constraints, allowing us to study more advanced physics-based methods." Binkowski and his team will use the 20 million hours of computer time awarded on the Intrepid to study protein-ligand binding interactions. The team will also evaluate and validate the predictive power of bimolecular simulations through collaboration with the Center for Structural Genomics of Infectious Diseases.

Jeff Greeley, a materials scientist, was awarded 15 million hours of supercomputing time on Argonne's Intrepid to continue an investigation of materials at the nanoscale (a nanometer is one billionth of a meter). Greeley leads a collaboration seeking to understand the electron
