Simulation and modeling of a single bus tightly coupled multiprocessor system

This paper presents a new queuing approach for the modeling of single bus tightly coupled multiprocessors, and a new simulation method which allows for its analysis. The model considers the macroscopic behavior of the multiprocessor, as well as the local program behavior. A new simulation method for each processing element, in the multiprocessor, is also presented. An expansion of the simulator for a multiprocessor system is also described. This expansion takes into account the fact that the workload distribution may be either static or dynamic. The simulator is shown to be capable of addressing the steady state behavior of the multiprocessor model, as well as the transient behavior. Experimental results for a single processor are presented, along with a brief discussion of problems that arose during the simulation experiments.
