The practice of constructing simulation models which can be run on digital computers is a promising methodology for conducting experiments on large scale systems. By using such a model, the analyst can theoretically conduct many experiments which cannot be done on the system being analyzed due to lack of available time, lack of control over the environment, lack of the resources required to configure the system in the manner appropriate to the experiment, or unwillingness to disrupt normal system operation for purposes of experimentation. This paper describes the design and implementation of such a simulation model for a large-scale computing system. Emphasis is placed on the objectives of the model, the various compromises and assumptions which had to be made in the model itself, the collection of data from the system under test, the implementation of the model in the form of a digital computer simulation, and the effort made to validate the simulation. The discrepancies observed in the validation data are discussed, and further experiments are suggested. Author
