Foil 9 Basic pipeline operation

From CPS615-End of N-Body Discussion and Beginning of Numerical Integration Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 15 October 96. by Geoffrey C. Fox *
Secs 187.2
First step is to Circulate(shift) one position and calculate acelerations Fij and Fji in all index positions
Shifting pipeline (N-1) times gives correct algorithm but does not save "Newton's factor of two".
Just need (N-1)/2 steps when N is odd and N/2 steps when N is even which saves factor of two.
