Pushing the Limits:
Scientific Computing on Extreme Platforms*

Each new generation of supercomputer promises the ability to perform simulations on an unprecedented scale. As the size and complexity of supercomputers continues to increase, however, so to does the difficulty associated with effectively utilizing the new capability. I will discuss the results of three simulations that have made profitable use of the largest computers on earth: the solidification of a molten metal, the formation of a fluid instability and the dynamics of hot, dense plasma. In each case, a multidisciplinary team of physicists and computer scientists was able to overcome the substantial technical challenges involved and deliver simulations providing an unparalleled view into the physical behavior.

Biography

Dr. Streitz is Director of the Institute for Scientific Computing Research and Group Leader in the Modeling and Simulations Group at Lawrence Livermore National Laboratory.

He joined LLNL's Physical and Life Sciences Directorate as a computational physicist in 1999. Prior to his arrival at the laboratory, he was an assistant professor in the Physics Department at Auburn University in Auburn, Alabama. Dr. Streitz received his B.S. in Physics at Harvey Mudd College in Claremont, California and did his graduate work at the Johns Hopkins University in Baltimore, Maryland, where he received his Ph.D. in Physics in 1992. Following graduation, he joined the Theoretical Chemistry Section at the Naval Research Laboratory in Washington, DC as a National Research Council Research Associate.

Dr. Streitz became Group Leader for the Modeling and Simulations Group in the Physical Sciences Directorate in 2006, and was named the Director of the Institute for Scientific Computing Research in the Computation Directorate in 2008. He has been active as both an experimentalist and a computational physicist, with recent focus on developing supercomputer applications that push the limits of leadership-class computational capability to address forefront scientific problems. He has twice (2005 and 2007) led multi-institutional teams that were recognized with a Gordon Bell Prize for significant achievement in supercomputing. Research problems of interest include the kinetics of phase transformations, the microscopic origins of fluid instabilities, the dynamic response of materials and plasmas under extremes of pressure and temperature and the development of inter-atomic potentials that facilitate simulation of ever more complex materials.
