Simulation of a Multiprocessing System Using GPSS

A large General Purpose Simulation System (GPSS) model has been developed to simulate the throughput and capacity of an application-oriented multiprocessing system. The model represents the system in terms of the hardware and software resources and the competitors for these resources. This paper discusses the size of the model, the running time of the model, and the development cycle. It also tabulates the hardware and software resources and the mapping of these resources into GPSS. Some of the possible applications of a model of this nature are discussed as well as some of the GPSS features that were used to conserve computer running time. Finally, some conclusions are drawn based on having developed a model of a large real-time multiprocessing system.
