LSU Webinar
Title: From Black Holes to Gamma-Ray Bursts
Featured Presenters:
Steven Brandt, Center for Computation & Technology, Louisiana State University
Erik Schnetter, Center for Computation & Technology and Department of Physics & Astronomy, Louisiana State University
Computational challenges involving gravitational physics and its potential to advance the field of computer science are still unfolding. Modeling a source for Gamma Ray Bursts (GRB) in full generality will likely require months long calculations on zeta flops machines. For that kind of science to take place, the Cactus framework will need to be continuously ported to newer and better architectures and be tested on ever larger scales.
LSU has developed a Cactus simulation of an inspiraling binary black hole system using over 5,800 cores for large-scale testing and online remote visualization. At SuperComputing 2008, the largest uniform grid evolution of a black hole collision to-date was performed using an 8003 sized data set. During this webinar, Drs. Erik Schnetter and Steven Brandt will present their work, and discuss how their simulation results will be used to carry out further scientific research and identify ways to improve scaling and performance.
