NPAC Activity in Colliding Black Hole Grand Challenge Collaboration

May 5 and 6, Pittsburgh Geoffrey Fox This talk summarizes the proposed NPAC role in the NSF sponsored grand challenge in numerical relativity (colliding black holes in particular). This grand challenge has several interesting features. The calculations will allow one to interpret observations from the new generation of gravitational wave detectors -- in particular the large LIGO system being built by Caltech and MIT with NSF funding. Black hole collisions are expected to be a particularly large and distinctive source of gravitational waves. These waves are an unambiguous prediction of Einstein's equations but have never been detected directly upto now. The simulations involve solutions of sets of partial computers are both necessary and sufficient for reliable numerical results. The grand challenge collaboration involves eight university groups led by Professor Richard Matzner from Texas. The computer science work is responsibility of Texas(Browne), Syracuse(NPAC) and Illinois (Saylor,Saied). There are several interesting similarities and differences between the computer science needs for numerical black hole physics and computational fluid dynamics. Some important HPCC technologies are High Performance Fortran, MPI, structured Adaptive grid generation, high level domain specific interfaces and computational toolkits. NPAC's role also includes preparation of educational material which will be first used in Computational Science class CPS713 in fall 1994.
