N-Body simulation Author: Martin Anuonye

This program is set up to run the n-body simulation on multiple particles on either a model of the solar system, or for a user specified number of particles.

Run this program with command line arguments for the timestep size, number of timesteps, and the frequency to dump the state in order to run the simulation on a model of the solar system. (./executable .01 20 5)

Or, run the program including a argument for the number of random particles you would like before the timestep size argument (./executable 30 .01 20 5)

Simulation Benchmark:

100 particles dt=1 for 10000 steps: 46587285 microseconds 1000 particles dt=1 for 10000 steps: 1005802831 microseconds Solar system with dt = 200 and for 5000000 steps: 2396702143 microseconds
