Foil 2 Abstract of Laplace Example for CPS615

From CPS615 Laplace Example -- Programming Models and Performance CPS615 Basic Simulation Track for Computational Science -- Fall Semester 97. by Geoffrey C. Fox
This takes Jacobi Iteration for Laplace's Equation in a 2D square and uses this to illustrate:
Programming in both Data Parallel (HPF) and Message Passing (MPI and a simplified Syntax)
SPMD -- Single Program Multiple Data -- Programming Model
Stencil dependence of Parallel Program and use of Guard Rings
Collective Communication
Basic Speed Up,Efficiency and Performance Analysis with edge over area dependence and consideration of load imbalance and communication overhead effects.
