This paper describes work carried out to port a continuous system simulation tool (SLIM) to the SIMD/MIMD environment provided by a Parsytec Supercluster involving a T800 transputer based parallel system. For the task considered (involving up to 17 processors) the speed-up of the exeution process was found almost linearly dependent on the number of processors and for 17 processors the speed-up factor was nearly 14.5 times. Howver relative error values were found to increase as the number of processors increased, probably due to problems associated with the large amount of calculated data transferred from the transputer array to the main memory of the front-end processsor. The paper concludes with suggestions about how performance could be improved for this type of application.
