DescriptionAlgorithms such as fast N-body methods, coupled with the extraordinary increase in computational power over the past three decades, have played a major part in the process of understanding complex physical systems. In this talk, we provide some context and history of gravitational N-body simulations and discuss the evolution of the parallel hashed oct-tree N-body algorithm and the problems it has been applied to over the years since its publication. We touch on concurrent evolution in hardware, such as Beowulf clusters and the Cloud as well as physical applications in cosmology, galaxy formation, supernovae, hydrodynamics and planet formation.
