Cactus Resources

The computational challenges involving gravitational physics 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.

In the accompanying white paper and webcast recording, LSU Researchers Erik Schnetter and Steven Brandt present the results of their research on the computational challenges of gravitational physics, black hole evolutions and modeling Gamma Ray Bursts (GRB).
