In this video from the 2013 National HPCC Conference, Don Lamb from the University of Chicago presents: Scientific Discovery Through HPC Simulations of High Energy Density Physics Experiments.
The availability of multi-petaflop computers and the advent of high-power laser systems have created new opportunities to explore the properties of matter at high temperatures, densities, and pressures. This research in high energy density physics is of great importance for astrophysics, material science, and inertial confinement fusion, among other fields. As an example, the generation of magnetic fields by asymmetric shocks is widely invoked as the source of cosmic magnetic fields and is of high interest in inertial confinement fusion. As another example, amplification of magnetic fields by turbulence is a “holy grail” of both computer simulations and laboratory experiments. In this talk, I describe large, multi-scale, multi-physics simulations validated by high-powered laser experiments that are providing new insights into these fundamental physical processes.”
