TRAPPER: A Graphical Programming Environment for Parallel Systems

TRAPPER is a graphical programming environment which supports the development of parallel applications. The programming environment is based on the programming model of communicating sequential processes. TRAPPER contains tools for the design, mapping and visualization of parallel systems. The Designtool supports a hybrid program development, where the parallel process structure is described using a graphical representation and the sequential behavior is described by sequential program code. The connguration of the target hardware and the mapping of the application onto the hardware is supported by the Conngtool. During run-time, the monitoring-system records events which can be animated by the Vistool and the Perftool which visualize the behavior of the hard-and software components. This paper describes the support of two machine independent message passing interfaces: PVM (Parallel Virtual Machine) and PARMACS (Parallel Macros).
