TITLE:

COMPUTATIONAL SCIENCE AT LAWRENCE LIVERMORE NATIONAL LABORATORY (No. 58)

DATE:

Friday, November 5th, 2004

TIME:

3:30 PM

LOCATION:

GMCS 214

SPEAKER:

Steven F. Ashby, Deputy Associate Director, Center for Computing Applications and Research, LLNL

ABSTRACT:

Large-scale simulation plays an increasingly important role in many scientific and engineering applications, including those in the defense, energy, and life sciences. The time and length scales of interest in many physical and biological processes span several orders of magnitude, thus requiring the use of sophisticated numerical methods and massively parallel computers.

Dr. Ashby will discuss some of the challenges inherent in terascale simulation, with an emphasis on the computational science activities at Lawrence Livermore National Laboratory, which currently houses more scientific computing horsepower than any other facility in the world. After giving a brief overview of the Laboratory, he will describe the LLNL simulation environment and highlight some of its computer science and mathematics research efforts. The majority of the presentation will be spent surveying a number of examples of computational science at the leading edge: showing how large-scale scientific simulation is being used to advance scientific discovery. In particular, this presentation will emphasize the importance of combining simulation with theory and experiment via illustrative case studies drawn from a variety of scientific and engineering application areas.
