Modularization and process replication in a visual parallel programming language
Guido Wirtz · 2002
Managing the graphical complexity of real-life programs expressed in visual programming languages is a great challenge in each visual programming environment. Besides general methods like displaying/layouting graphs and icons on different levels of abstraction or organizing multiple window environments, built-in language mechanisms which permit the structured and modular design of visual programs are essential to overcome this problem. We address these problems by discussing a concept for visual modules in a diagrammatic parallel language as well as a method to describe massive parallel programs consisting of hundreds of processes by means of a visual replication mechanism.>
