Great Power, Great Responsibility: Recommendations for Reducing Energy for Training Language Models
This addresses the urgent need to reduce energy consumption in NLP and machine learning, though it is incremental as it builds on existing methods for energy efficiency.
The paper tackles the unsustainable energy growth in training language models by investigating techniques like power-capping and hardware tuning, achieving a 15% reduction in energy usage with minimal computational overhead.
The energy requirements of current natural language processing models continue to grow at a rapid, unsustainable pace. Recent works highlighting this problem conclude there is an urgent need for methods that reduce the energy needs of NLP and machine learning more broadly. In this article, we investigate techniques that can be used to reduce the energy consumption of common NLP applications. In particular, we focus on techniques to measure energy usage and different hardware and datacenter-oriented settings that can be tuned to reduce energy consumption for training and inference for language models. We characterize the impact of these settings on metrics such as computational performance and energy consumption through experiments conducted on a high performance computing system as well as popular cloud computing platforms. These techniques can lead to significant reduction in energy consumption when training language models or their use for inference. For example, power-capping, which limits the maximum power a GPU can consume, can enable a 15\% decrease in energy usage with marginal increase in overall computation time when training a transformer-based language model.
