Energy efficiency is a growing concern for modern computing, especially for HPC due to operational costs and the environmental impact. We propose a methodology to find energy-optimal frequency and number of active cores to run single-node HPC applications using an application-agnostic power model of the architecture and an architecture-aware performance model of the application. We characterize the application performance using Support Vector Regression. The power consumption is estimated by modeling CMOS dynamic and static power without knowledge of the application. The energy-optimal configuration is estimated by minimizing the product of the power model and the performance modelu0027s outcomes. Results for four PARSEC applications with five different inputs show that the proposed approach used about 14X less energy when compared to the worst case of the default Linux DVFS governor. For the best case of the DVFS scheme, 23% savings were observed, with an overall average of 6% less energy. |
