This article proposes a novel architectural model which augments the latest developments in automatic program parallelization and distributed systems to achieve a level of practicality as yet unknown to either field. Today's premier automatic parallelization model is well suited to implementation on a network of commodity workstations (NOW) using only a very thin layer of software support. We describe a parallelizing compiler framework which greatly simplifies the parallelization of even highly complex sequential applications while producing extremely effective parallelizations for the NOW. We further show how our model greatly enhances programmer productivity through the use of minimally invasive C++ transformation techniques, aiding both debugging and portability.
