Summary

Resource sharing in multiprocessor systems has a strong influence on the speed-up of the processing elements. Analytic computational methods, e.g. queueing theory, do not provide time-dependent solutions by tolerable effort,’ whereas simulation often requires a great deal of computational time and is more difficult to validate. In order to overcome these disadvantages, the paper presents a model that combines analytic computation and simulation. The time-dependent solution of the model under time-dependent load is obtained by the simulation package FORCASD. For reasons of state reduction and decrease of computational effort the hardware layer is modeled by a queueing model. The results are validated by measurements in the M5PS multiprocessor system.
