A multiprocessor system for dynamic system simulation
Article Abstract:
The basic goal of the project reported in this paper was to design and implement an experimental multimicroprocessor system dedicated to the real-time parallel simulation of dynamic systems of various degrees of complexity. The implemented multimicroprocessor called RAMS is also used to study the parallelization concepts of dynamic system models. Potential application of RAMS is in the process control area. The RAMS hardware architecture and software concepts, in particular the automatic synthesis of RAMS application software, are given in some detail. The problems of both task creation and scheduling in the non-deterministic RAMS environment are addressed. The experimental results show the power of RAMS through the parallel simulation of a case study dynamic system. (Reprinted by permission of the publisher.)

Simulation experiments for performance analysis of multiple-bus multiprocessor system with nonexponential service times
Article Abstract:
A simulation model (program) is constructed for performance analysis of multiple-bus multiprocessor systems with shared memories. It is assumed that the service time of the common memory is either hypo- or hyperexponentially distributed. Processing efficiency is used as the performance index. To investigate the effects of different service time distributions on the system performance, comparative results are obtained for a large set of input parameters. The simulation results show that the error in approximating the memory access time by an exponentially distributed random variable is less than 6% if the coefficient of variation is less than 1, but it increases drastically with this factor if it is greater than 1.
