TRAPPER - A GRAPHICAL PROGRAMMING ENVIRONMENT FOR PARALLEL SYSTEMS

We present a graphical programming environment for parallel systems ca lled TRAPPER(TM). TRAPPER supports the development of industrial appli cations which require high computing power. The programming environmen t is based on the programming model of communicating sequential proces ses. TRAPPER contains tools for the design, mapping, visualization and optimization of parallel systems. The Designtool supports a hybrid pr ogram development, where the parallel process structure is described u sing a graphical representation and the sequential behavior is describ ed using textual representations. The configuration of the target hard ware and the mapping of the application onto the configured hardware i s supported by the Configtool. During run-time, the monitoring system records software events like interprocess communication and measures t he computation and communication loads of the underlying hardware. The run-time behavior of the software is animated by the Vistool, the loa d behavior of the hardware is displayed by the Perftool. The first tar get systems are transputer-based systems as well as workstation cluste rs and parallel supercomputers with the standard interfaces PVM, PARMA CS or MPI.
