Supercomputing Black Hole Mergers with Blue Waters

Manuela Campanelli, Director of CCRG

“The mathematics involved in simulating these events is very sophisticated because one has to solve the equations of Einstein’s general relativity and magneto-hydrodynamics all together. The problem also requires very advanced supercomputers running programs on tens of thousands of CPUs simultaneously, and the use of sophisticated techniques for data extraction and visualization. Petascale numerical simulation is therefore the only tool available to accurately model these systems.”

Podcast: Supercomputing the Impact of Deepwater Horizon

Deepwater Horizon

Lead by Project Principal Investigator Annette Engel from the University of Tennessee at Knoxville, the research has uncovered fundamental changes in the types of bacterial communities associated with oil and carbon degradation of importance to oil quality and quantity, as well as to the overall ecosystem of the Gulf Coast area.

Podcast: Using Allinea Programming Tools to Speed XSEDE Supercomputing Research

“In my humble opinion, I think that debuggers and profiling tools are far too infrequently used. And it’s not because they’re not there. It’s because people just either don’t know about them, don’t do training on them, or don’t know how to use them. We’re in a state where we have less cycles than we’ve ever had per request, right? So being able to take full advantage of those cycles by having optimized code and optimized run patterns is crucial. Otherwise, you’re just not going to be able to get your work done and the science won’t get done.”
