Tony Mezzacappa of the Physics Division led a team that was awarded 7 million processor hours on Jaguar and 300,000 on Phoenix. The project is aimed at gaining a better understanding of core collapse of supernovae. These are the single most important source of elements in the universe and understanding the process of massive stars in death throes is one of the most important mysteries in astrophysics.

A project led by David Dean of the Physics Division, awarded 5 million processor hours on Jaguar, aims to calculate the physical properties of nuclei based on interactions among neutrons and protons. This will help scientists gain a better understanding of nuclear forces and characteristics relevant to nuclear astrophysics and other applications.

Robert Harrison of the Computer Science and Mathematics Division leads a team that was awarded 3 million processor hours on Jaguar and 300,000 on Phoenix. The goal of the project is to improve the efficiency of a desired chemical reaction. Researchers note that catalytic processes are directly involved in the synthesis of 20 percent of all industrial products. Within the DOE mission, catalysts feature prominently in cleaner and more efficient energy production.

Meanwhile, Don Batchelor of the Fusion Energy Division and colleagues were awarded 2 million processor hours on Jaguar to help understand and predict the effects of high-power radio frequency waves on plasma stability. This is of significant scientific and economic importance with a direct benefit to the International Thermonuclear Experimental Reactor project.

In a project awarded 1 million processor hours on Jaguar, Patrick Worley of the Computer Science and Mathematics Division leads a team focusing on understanding the performance of the Cray supercomputers and helping to ensure that they are being used as efficiently as possible.
