NSF Grand Challenge in Numerical Relativity -- Initial Computer Science
Plans
This presentation by Geoffrey Fox at January 94 CRPC annual meeting
describes the NSF Grand Challenge in Numerical Simulation of Black Hole
Dynamics. 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.
