Argonne Leadership Computing Facility
"Petascale Core-Collapse Supernova Simulation"

DATE: January 22, 2010 to January 22, 2010
TIME: 3:00 PM - 4:00 PM
SPEAKER: Dr. Bronson Messer, Deputy Group Lead, Scientific Computing, Oak Ridge Leadership Computing Facility
LOCATION: Building 240 / Conference Center Room 1404, Argonne National Labortory

Description:
The advent of petascale computing brings with it the promise of substantial increases in physical fidelity for a host of scientific problems. However, the realities of computing on these resources are daunting, and the architectural features of petascale machines often require considerable innovation for effective use. Nevertheless, there exists a class of scientific problems whose ultimate answer requires the application of petascale (and beyond) computing. One example is ascertaining the core-collapse supernova mechanism and explaining the rich phenomenology associated with these events. These stellar explosions produce and disseminate a dominant fraction of the elements in the Universe; are prodigious sources of neutrinos, gravitational waves, and photons across the electromagnetic spectrum; and lead to the formation of neutron stars and black holes. I will describe our recent multidimensional supernova simulations performed on petascale platforms fielded by the DOE Office of Science and the National Science Foundation.
