For performance evaluation of multiprogramming systems a queueing model with a finite waiting room is considered. The model assumes that a computer system consists of a central processor and identical input/output channels and that the service times of both units are exponentially distributed independent random variables. Then the queueing model is described as M/M/S (N) where S is number of input/output channels and N is degree of multiprogramming. Processor productivity is defined by a steady state probability. Compared with measured and calculated data of processor productivity the model validation is discussed. Furthermore an overhead of a monitor in multiprogramming systems is also considered.
