A graphical user interface for data-parallel programming

The authors have developed a graphical user interface that supports the development of data-parallel programs for distributed-memory multiple instruction multiple data (MIMD) computers. The name of the tool is Intercom, since it facilitates programmer interaction with the compiler. Intercom allows the programmer to edit data-parallel programs, invoke the compiler, and examine the places in the program where the compiler has inserted calls to the message-passing library. Intercom also provides automatic version control, which allows the programmer to revert to earlier versions of the program at any point in the editing session. Intercom is a Motif-based application running in an X11 environment. Currently, Intercom is being used to support the development of programs written in the Dataparallel C language
