The Impact of GPU DVFS on the Energy and Performance of Deep Learning: an Empirical Study

Tang, Zhenheng, Wang, Yuxin, Wang, Qiang et al.

Understand

Over the past years, great progress has been made in improving the computing power of general-purpose graphics processing units (GPGPUs), which facilitates the prosperity of deep neural networks (DNNs) in multiple fields like computer vision and natural language processing.

  • A typical DNN training process repeatedly updates tens of millions of parameters, which not only requires huge computing resources but also consumes significant energy.
  • In order to train DNNs in a more energy-efficient way, we empirically investigate the impact of GPU Dynamic Voltage and Frequency Scaling (DVFS) on the energy consumption and performance of deep learning.
  • Our experiments cover a wide range of GPU architectures, DVFS settings, and DNN configurations.
