Mechanistic-Empirical Processor Performance Modeling for Constructing CPI Stacks on Real Hardware

Analytical processor performance modeling has received increased interest over the past few years. There are basically two approaches to constructing an analytical model: mechanistic modeling and empirical modeling. Mechanistic modeling builds up an analytical model starting from a basic understanding of the underlying system - white-box approach - whereas empirical modeling constructs an analytical model through statistical inference and machine learning from training data, e.g., regression modeling or neural networks - black-box approach. While an empirical model is typically easier to construct, it provides less insight than a mechanistic model.
