Annotated directed graph representations of parallel programs simplify programming and debugging by providing a single, consistent framework that separates a program's sequential computations from its parallel structure. We discuss visual parallel programming and how it is implemented in two integrated programming environments-Computationally Oriented Display Environment (CODE) and Heterogeneous Network Computing Environment (Hence)-that represent parallel programs as directed graphs.>
