摘要：
A study, with focus on trajectory simulation, of next generation super computer technology is presented. Specifically, we utilize commercial off-the-shelf Graphics Processing Units (GPUs) to calculate gravitational force using the polyhedral method and spherical haxmonics. Experiments comparing speed and accuracy show a single GPU to be capable of outperforming a single conventional CPU by an order of magnitude at the expense of some accuracy.
