COMPUTER SYSTEMS ANALYSIS METHODOLOGY:STUDIES IN MEASURING, EVALUATING, AND SIMULATING COMPUTER SYSTEMS

摘要

This Report summarizes the results of a group of com¬puter systems analysis and simulation studies performed under a NASA research contract. It represents the text of a briefing presented at four NASA centers (Goddard, Langley, Marshall, and MSC-Houston) in April 1970. The discussion, which concentrates on the key results of individual studies and their applicability to the design, development, and management of complex computer systems, should be of in¬terest to planners, managers, and analysts of both complex computer systems and mission-oriented systems.nThe studies were coordinated into three major efforts:n1) The development of a set of design principles for languages to model and simulate computer systems by attempting to design and implement a prototype language called ECSS (Extendable Computer System Simulator).n2) The evaluation and extension of the state-of-the-art of using software and hardware devices to measure and analyze the performance of complex computer systems.n3) The provision of greater perspectives on the re¬lationship between computer performance and man-computer performance by performing and analyzing controlled experiments in man-computer problem-solving.
