Performance of a virtual memory

Abstract

This paper reports the results of simulation experiment of a model of a virtual memory computer. The model consists of three major subsystems: Program Behavior, Memory Allocation and Secondary Storage. By adapting existing models of these subsystems an overall model for the computer operation is developed and its performance is tested for various design alternatives. The results are reported for different paging devices, levels of multiprogramming, job mixes, memory allocation scheme, page service scheduling and page replacement rate.
