1 Positions and velocities are 3 N dimensional arrays, X and V
2 other variables
  • M - spread masses to another 3xN array
  • h - step size
  • ns - number of time steps
3 subroutine for numerical method will take these arguments and update X and V.
4 A subroutine called Grav (dataparallel) or MPGrav (message parallel) is assumed to compute new accelerations
