Foil 11 SPMD or SCMD
Single Program (code) Multiple Data

From CPS615 Laplace Example -- Programming Models and Performance CPS615 Basic Simulation Track for Computational Science -- Fall Semester 97. by Geoffrey C. Fox
A particular way of using MIMD machines - DOMINANT successful use so far.
Each processor runs same program but in general executes different instructions at different times.
Will later see corresponds to "loosely synchronous problems".
Style of current program example -- note although each doing roughly same thing -- i.e. updating grid points -- each node is NOT at same point in update at each clock cycle
