Towards a realistic performance model for networks of heterogeneous computers

Abstract

This paper presents experimental work undertaken towards the development of a realistic performance model for non-dedicated networks of heterogeneous computers. Unlike traditional models, it is aimed at parallel computing on common networks of computers and distributed computing on global networks. It takes into account the effect of paging and differences in the level of integration into the network of computers, with the inevitable fluctuation in the workloads of computers in such networks. Some preliminary experimental work undertaken in support of the development of the model is briefly discussed. Based on the results of these experiments some key parameters of such a model are proposed. © 2005 by International Federation for Information Processing.
