Foil 45 Performance for Increasing Stencil

From CPS615 Laplace Example -- Programming Models and Performance CPS615 Basic Simulation Track for Computational Science -- Fall Semester 97. by Geoffrey C. Fox
The previous foil showed that increasing stencil made slight improvements!
This foil shows that larger stencils have much lower overheads (and hence better parallel performance) than simple Laplace's equation with 5 point stencil
