Foil 31 Computer Architectures - MIMD - Distributed Memory

From MetaComputing -- MRA Meeting Part I:Concepts and Issues Tutorial for CRPC MRA Meeting at Cornell -- May 7 1996. by Mark Baker, Geoffrey Fox
A Major Concern
A major concern is data decomposition -- how to divide arrays among local CPUs to minimise communication
Here is a major distinction between shared- and distributed-memory:
In SM the processors don't need to worry about communicating with their peers, only with the central memory, while in the DM there really isn't anything but the processors.
