N-Body Simulation Project at Cal Poly

The goal of the N-Body problem is to predict the motion of a set of n objects interacting with each other by some force, e.g. the gravitational force. N-Body simulations have been used in particles simulation such as astrophysical and molecular dynamics simulations. There are a number of approaches for solving the N-Body problem, such as the Barnes-Hut algorithm, the Fast Multipole method, the Parallel Multipole Tree Algorithm method and the direct calculation method. In the direct calculation approach, for every particle in the system, the force between that particle and every other particle in the system is calculated, resulting in an O(n2) operation for each time step where n is the number of particles in the system.
