An investigation of program exchange methods for multiprogramming environment.

Abstract

An investigation of program exchange techniques and methods of evaluating such procedures is conducted. Basic hardware and system parameters vitally affecting program exchange are discussed. The basic program exchange methods covered are 1) the Complete Program Exchange 2) the Block or Page Exchange and 3) the Completely Integrated System Exchange. The investigation is conducted using heuristic analysis, and a simulation study is conducted on selected methods. The combined analysis not only evaluates present methods but provides a guide for evaluating and selecting an Exchange technique for any system configuration . A complete multiprogramming system simulator and a specific technique for status preservation are presented as Appendices.
