ABSTRACT

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This award supports research to develop software infrastructure required to efficiently solve the Einstein Equations of General Relativity on the next generation of supercomputers. This capability will then be exploited to evolve systems containing two black holes of unequal mass, an important potential source of gravitational waves detectable by ground-based and space-based detectors such as LIGO and LISA. Computer simulations of binary black holes provide gravitational waveforms that can be used to search for weaker signals than could be found without this information. The new supercomputers achieve speed breakthroughs by increasing the number of cores per CPU to tens or even hundreds. Computer codes designed for today's computers must be redesigned to take maximum advantage of the new architechture. This project is part of an ongoing effort at RIT to develop new, highly efficient, high-accuracy numerical algorithms for General Relativity.
