Abstract

A model of high-performance computers is derived from instruction timing formulas, with compensation for pipeline and cache memory effects. The model is used to predict the performance of the IBM 370/168 and the Amdahl 470 V/6 on specific programs,/and the results are verified by comparison with actual performance. Data collected about program behavior is combined with the performance analysis to highlight some of the problems with high-performance implementations of such architectures.
