Performance Modeling - a Structured Approach.
Abstract
Computer system performance is normally evaluated in terms of the three primary performance measures: throughput, turnaround time and availability. Models provide a cost effective approach to the evaluation and prediction of performance. A large number of models currently exist for analyzing the performance of a subsystem of a computer. However, only a limited number of models exist which can be used to analyze the performance of a system in terms of some basic collection of job descriptors and system descriptors. In the report such a model is described which can be used for analyzing the performance of the system as a whole as a function of: the total amount of CPU time required by a job or process, the average length of a requested CPU interval, the average length of an I/O delay and the number of statistically identical jobs in the system. The formulation of the model permits additional detail to be incorporated when deemed desirable. (Author)
