This proposal is about exploring the use of alternative technologies,
such as the Sony Playstation 3 gaming console, multimedia workstations
and similar hardware for scientific computing. The key aspect of these
technologies is that they use a processor that is based on a hybrid
approach -- using elements from both traditional CPUs and GPUs. If
successful, this approach would yield a significantly higher cost
effectiveness (measured as performance-per-dollar and performance-per-
watt) compared with traditional Beowulf compute clusters. More
specifically, the project will focus on investigating the performance
of such hardware for projects in numerical relativity and (LIGO) data
analysis. Preliminary work that has been performed in this direction
by the PI has yielded very promising results. If such clusters yield
these benefits, searches of LIGO data and simulations of gravitational
wave sources could move into compute intensive regimes not now possible.
