Abstract : The multi-computer system, as one type of multi-system, is amenable to simulation experiment studies. The description of the salient characteristics of the hardware and operating system software for a multi-computer system is reported. A general technique for representing a set of programs that such a multi-computer system might execute was developed. This method of programrepresentation was used to characterize the TACFIRE Mission Programs at the Division Artillery level. With the simulation model in the form of a computer program for execution on the IBM 7044/90/94, experiments were run using the simulated TACFIRE Programs. These experiments were repeated for one, two and three CPU systems, and resulted in data giving over-all system performance, relative system performance and performance on a par program basis. The major performance criteria in this data is the turn-around time. Mainframe and peripheral device overhead figures were accumulated, as well as disc utilization and waiting times, and data characterizing the performance of the operating system. (Author)
