The aggregate server method is an approximate, iterative technique for analyzing the delays programs encounter while waiting for entry into critical sections, non-reentrant subroutines, and similar software structures that cause processing to become serialized. The method employs a conventional product form queueing network comprised of servers that represent actual I/O devices and processors, plus additional aggregate servers that represent serialized processing activity. The parameters of the product form network are adjusted iteratively to account for contention among serialized and non-serialized customers at each physical device.

This paper describes an event trace monitor implemented on Version 1.6 of the VMS operating system at Purdue University. Some necessary VMS terminology is covered first. The operation of the data gathering mechanism i...
An algorithm for generating a page reference string which exhibits a given working set size behavior in the time domain is presented, and the possible applications of such a string are discussed. The correctness of th...
A system model is a tool used to predict system performance under changing conditions. There are two widely used modeling techniques: One based on discrete event simulation and one based on queuing theory models. Beca...
