Abstract

Multiprocess programs date back to the earliest multiuser operating systems. Recently this venerable programming methodology has been adapted to programming computer systems that consist of multiple processors. In this paper we discuss the large grain dataflow programming model and its strengths compared to the process model.Unlike the process model, the dataflow model was developed for parallel processors. Using dataflow it can be shown that a program (e.g., a graph) will be free from race conditions (deterministic). Large grain dataflow gives the programmer a framework that can be used in program design. Large grain dataflow programming is discussed in the context of the LDF 100, a distributed memory parallel processor.
