WE REPORT HERE ON A GRAPH EDITOR, CALLED PARAGRAPH, THAT SUPPORTS THE PROGRAMMING OF MASSIVELY PARALLEL COMPUTATIONS. IT PROVIDES A FLEXIBLE MECHANISM FOR THE CONCISE SPECIFICATION OF FAMILIES OF ANNOTATED GRAPHS, ADDRESSING THE PROBLEMS OF USER-ANNOTATION AND SCALE INDEPENDENT GRAPH MANIPULATION. IT HAS BEEN INTEGRATED INTO OUR PROGRAMMING ENVIORNMENT, WHERE IT SERVES AS THE BASIS FOR TOOLS SUPPORTING COMMUNICATION ABSTRAC- TIONS IN PROGRAM SPECIFICATION AND DEBUGGING. ITS EXTENSION TO A NUMBER OF OTHER PARALLEL PROGRAMMING ENVIRONMENTS WOULD BE STRAIGHTFORWARD.
