Performance Prediction for Processors and External Resources

Regular forms of Amdahl’s law and the universal scalability model are functions of the number of processors p alone, therefore modelling only data sets with a single machine varying in its processor count. This paper demonstrates how these performance models can be expressed in terms of intrinsic machine characteristics such as: processor clock; external resource access speed; total threads; etc. Our new models broaden all previous applications including: sensitivity analysis, forecasting, scaling; while providing new ones such as evaluations for: migration, purchase, upgrading, etc.
