Similarity Measurement for Proxy Application Fidelity

Authors: Si Chen (Emory University), Omar Aaziz and Jeanine Cook (Sandia National Laboratories), and Avani Wildani (Emory University)

Abstract: Proxy applications, designed to represent similar but much larger and more complex parent applications, are widely used for system co-design and procurement. Quantitative validation, however, to prove that proxies are faithful representations of their parents, is missing. In this work, we apply several machine learning-based methods to quantitatively demonstrate the correspondence of proxy to parent in their underlying node and memory hardware behavior. We show that different similarity measurements have similar results while evaluating the proxy application fidelity, and most proxies are good representations of their parents.
