A message based operating system promoting parallel programming

A description is given of a high level of programming where a graphical representation of a program is provided which uses C macros as a lower-level implementation tool. The programmer is challenged with the task of constructing the graph and the contents of the modules. The system interprets the graph, yielding a parallel executable form of the graph targeted for a real machine. A set of commonly used modules is maintained by the system library and the programmer adds the necessary modules when solving a specific problem. To add a module the programmer specifies data ports and the module´s purpose. This allows other programmers to use modules previously created, enhancing programmer efficiency. The proposed system allows the programmer to concentrate on potential parallelism at a high level using predefined user-specific modules. Natural data flow is used in program construction, which requires little programmer training
