An execution time animation system for transputers

A tool for visualizing the communication events in a parallel processing system consisting of transputers is presented. A user program written in OCCAM language is preprocessed by this tool to add run-time event timing mechanisms. Time-stamping data thus obtained is then displayed by a second tool in a graphical format which accurately illustrates any channel or link communication occurring during the execution of the user program. This knowledge enables the user to gain a wider insight in the improvement of his/her implementation.
