A Model for Disc Locality Referencing
Department of Computer Science, University College London, Gower Street, London, UK
A model for disc locality referencing is presented which, unlike previous models, allows device efficiency to be assessed in real time. Two types of localizations are distinguished: inter-cylinder localization and intra-cylinder localization. The present study allows these factors to be quantitatively analysed. The results of the model are compared with empirical measurements, and close agreement is obtained.
