In this paper, we accelerate a gravitational physics numerical modelling application using hardware accelerators – Cell processor and Tesla CUDA GPU. We describe these new technologies and our approach in detail, and then present our final performance results. We obtain well over an order-of-magnitude performance gain in our application by making use of these many-core architectures.
