An introduction to the processing graph method

Abstract

The Processing Graph Method (PGM) technology is a paradigm that provides the engineer/system designer with an environment to specify and maintain applications in a form which is invariant over a wide range of MIMD message passing parallel architectures. We will give the reader the flavor of this approach by providing a description of an application; illustrating how that application is represented; showing typical results obtained by running the application; providing a short description of the atoms that are used to build the application; and providing a short discussion of the technical issues to which PGM must respond.
