The Swarm-NG package helps scientists and engineers harness the power of GPUs for high throughput integration of n-body systems. Swarm-NG focuseson the integration of an ensemble of N-body systems evolving under Newtonian gravity. Swarm-NG does not replicate existing libraries that calculate forces for large-N systems on GPUs, but rather focuses on integrating an ensemble of many systems where N is small. This is of particular interest for astronomers who study the chaotic evolution of planetary systems.
