Simulating the performance of a multiprocessor operating system

Abstract

The authors constructed a simulation model, using the PAWS simulation modeling tools, to predict the performance of a shared memory multiprocessor operating system. The operating system is divided into five distinct sections, called empires. They used the model to predict the efficiency of this paradigm of multiprocessing for the Hewlett-Packard HP-UX Release 8.0 operating system. The simulation results show that the empires architecture is effective in providing enough concurrency for a four-way computer under a program development workload. The authors describe the model and its parameters, present and discuss the results, provide a statistical analysis of the data, and analyze the results.<>
