IBM Contributions to Computer Performance Modeling

by Y. Bard, C. H. Sauer
Performance modeling can be used throughout the life of a computer system, from initial design, through implementation, configuration (and reconfiguration) and even tuning. Performance models are usually solved by numerical techniques, where possible, and by simulation, otherwise. This paper summarizes IBM's contributions to performance modeling and the solution of performance models.
