Multiprocessor systems are high-performance systems that are making a rapid foray into the mainstream of computing. To realize their full potential, however, consideration must be given to their design. The design of the interconnection networks is particularly critical. Performance studies based on analytical and/or simulation models are conducted to evaluate alternate designs. The analytical models are either so complex that they are intractable, or are based on assumptions so restrictive that they are unrealistic. Simulation models, on the other hand, are simple and can capture almost any level of realism. Their problems lie in high costs for their development and the specificity of their results. The research reported here addresses these issues in specific reference to the simulation of multiprocessor interconnection networks. General simulation is proposed to counter the development cost, and simulation-based meta-models are suggested for overcoming the lack of generality in simulation results. This paper describes a general simulation model as implemented in SLAMII.
