Foil 75 Representing the Message Parallel N-Body problem
From Fox Presentation Fall 1995 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95/96/97. byNancy McCracken and Geoffrey C. Fox
Positions and velocities are 3 N dimensional arrays, X and V
other variables
M - Masses are a N dimensional array
h - step size
ns - number of time steps
subroutine for numerical method will take these arguments and update X and V.
A subroutine called MPGrav (message parallel) is assumed to compute new accelerations
