MUPPET - a programming environment for message-based multiprocessors

MUPPET is a problem-solving environment for scientific computing with message-based multiprocessors. It consists of four part-concurrent languages, programming environments, application environments and man-machine interfaces. The programming paradigm of MUPPET is based on parallel abstract machines and transformations between them. This paradigm allows the development of programs which are portable among multiprocessors with different interconnection topologies. In this paper we discuss the MUPPET programming paradigm. We give an introduction to the language CONCURRENT MODULA-2 and the graphic specification system GONZO. The graphic specification system tries to introduce graphics as a tool for programming. It is also the basis for programming generation and transformation
