Meander Language and System - Overview

years in topics of parallelism resort to drawing when explaining a specific parallel situation, mechanism or whatever. Moreover, the evolving set of tools supporting parallel programming (debugging, visualization) is especially useful because of exploiting graphical methods. We propose the usage of graphical languages to specify parallel programs where parts of a graph may be connected or not, depending on the existence of logical relationships (e.g. causal ordering, communication). Although graphical methods are central in our approach, we are far from using graphics for all parts of a parallel program: purely sequential parts without communication and parallel control should be formulated in the old-fashioned way. Hence, we use a hybrid approach integrating textual and graphical representations into one language. Such a hybrid language provides the ideal basis for an integrated programming environment: The same graph which is used for drawin
