| A stochastic model of a priority multiprogramming computing system is analysed in the steady state. A version of the model in which preemption of input/output operations is allowed and one in which it is not allowed and considered. Expressions for the central processor utilisation factor and for the average residence-in-the-system times are obtained. The relative merits of the two types of systems and the problem of efficient allocation of priorities to jons with different CPU and I/O requirements are discussed, using the results for some special cases as illustration. |
