A software Instrumentation Package for use with the Extendable Computer System Simulator, Version 15 was written to facilitate the reporting of systems performance statistics in discrete system simulations. The software package was developed in the course of modeling the TRIDENT Strategic Weapon Fire Control System. The Instrumentation Package IP complements the Extendable Computer System Simulation language by creating data structures for statistics collection and by providing the mechanism for initialization, update and output of the contents of these structures. The end result of the IP is a set of specialized output reports which describe the activity of a simulated computing system during a user specified time interval. This report outlines the user input procedures and report options available with the software package. Detailed descriptions of the statistical collection methods, the functions of the IP routines and the interactions of the IP routines are included. Methods for updating the IP are also delineated. The software system is operational on the CDC 6700 computer at the Naval Surface Weapons Center, Dahlgren Laboratory, and the IBM 36091 computer at the Applied Physics Laboratory, Johns Hopkins University.
