A VM-Based Approach for Power Modeling

Power modeling is an essential building block for computer systems in support of energy optimization, energy profiling, and energy-aware application development. In 2024, I introduced VESTA, a novel approach to modeling the power consumption of applications with one key insight: language runtime events are often correlated with a sustained level of power consumption. When compared with the established approach of power modeling based on hardware performance counters (HPCs), VESTA has the benefit of solely requiring application-scoped information and enabling a higher level of explainability, while achieving comparable or even higher precision. I hope to continue on this track of discovering the deep connections between VM-events and power consumption while also providing practical solutions for mapping one to the other through the construction of power models.
