Abstract
Algorithms designed to efficiently solve the classical N-body problem of mechanics fit well on GPU hardware and exhibit excellent scalability on many GPUs. Their computational intensity makes them a promising approach for other applications amenable to an N-body formulation. Adding features such as autotuning makes multipole-type algorithms ideal for heterogeneous computing environments.
