Webcast on Using Cactus for Gravitational Physics Simulations

Webcast: From Black Holes to Gamma-Ray Bursts, hosted by SiCortex
LSU Center for Computation & Technology Researchers Steven Brandt and Erik Schnetter presented the results of their research on the computational challenges of gravitational physics, the use of the Cactus framework for modern black hole evolutions and modeling Gamma-Ray Bursts (GRB) in a recent webcast, hosted by SiCortex, Inc.
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 the webcast, Drs. Schnetter and Brandt also discuss how their simulation results will be used to carry out further scientific research and identify ways to improve scaling and performance.
This webcast is part of a series of Science-to-Science webcasts sponsored by SiCortex and intended to highlight the use of HPC systems in advancing scientific discovery. The webcast and associated white paper, Relativistic Astrophysics on the SiCortex Architecture, can be viewed on the SiCortex website.
