Parallel integration of planetary systems on GPUs
Jianwei Gao, Eric B. Ford, Jörg Peters · 2008
Direct numerical simulations of large numbers of planetary systems are key to the study extrasolar planetary systems. We investigate the potential of Graphics Processing Units (GPUs) to dramatically accelerate such calculations and enable new types of analyses. Here we report on a CUDA implementation of two different integrators, Verlet and Bulirsch-Stoer; that is, we are contrasting the relative efficiency of a low-memory-footprint, small-time-steps integrator with a more complex but highly stable integrator for best use of GPU resources.
