Executive Impact Summary
Our dynamic GPU power capping solution offers a strategic advantage for enterprises seeking to optimize their AI and HPC infrastructures for efficiency and sustainability.
The Problem: Inefficient Static Capping
Conventional fixed power-capping methods lead to suboptimal performance-energy trade-offs and do not adapt to varying real-world workloads, resulting in wasted energy and increased cooling costs for GPU-intensive operations.
The Solution: Adaptive ML-Driven Power Caps
Our machine learning-based model dynamically predicts the optimal GPU power cap by leveraging real-time system parameters like GPU utilization, memory, temperature, and frequency. This adaptive approach ensures efficient resource allocation tailored to specific workload demands.
The Value: Sustainable & Cost-Effective AI
Implementing this dynamic power-capping strategy translates directly into reduced operational costs through lower energy consumption and extended hardware lifespan due to improved thermal management. It fosters greener supercomputing infrastructures, aligning with sustainability goals without compromising critical AI/HPC performance.

As GPUs become increasingly popular in commodity hardware as well as High Performance Computing (HPC) systems, the need for sustainable computing is more critical. This work addresses the challenge of identifying the optimal operating power for GPUs to minimize energy consumption and operational temperature while incurring only minimal performance overhead. Conventional fixed power-capping approaches lack the ability to adapt dynamically, often resulting in suboptimal performance-energy trade-offs under real-world, varying workload conditions.
We developed five predictive models: XGBoost, CatBoost, Random Forest, Decision Trees, and Linear Regression. These models were designed to identify the optimal power cap based on key system metrics, including GPU utilization, memory utilization, frequency, and temperature. Tree-based models have been shown to excel in GPU power prediction tasks due to their ability to capture non-linear interactions and handle feature heterogeneity effectively. To ensure robust evaluation and mitigate overfitting, k-fold cross-validation was applied during training.
Our evaluation showed that among the predictive models, CatBoost Regressor achieved the lowest error (MSE: 4,018,389.22, MAE: 834.17) and the highest R² score (0.9761), indicating its superior ability to accurately predict optimal power caps. This strong performance confirms the viability of a machine learning approach for dynamic power management.
We evaluated our dynamic power capping model on two GPU-intensive tasks: training a YOLOv8 model and fine-tuning a BERT model. The dynamic model converged rapidly to the optimal static power cap, achieving significant energy savings and temperature reductions. For YOLOv8, we observed a 12.87% energy gain and 11.38% temperature reduction with only a 2.69% performance loss. For BERT, there was a 6.45% energy gain and 10.56% temperature reduction, with a 3.26% performance loss. These results highlight the model's effectiveness across diverse AI workloads.

Case Study: Adaptive Power Management for AI Workloads
Our research employed a robust experimental setup, utilizing an Nvidia RTX 4000 Ada GPU to test three distinct GPU-optimized kernels: a DenseNet classification kernel, a CUDA matrix multiplication kernel, and a CNN image processing kernel. These were combined into seven experimental programs, including individual and concurrent runs. This comprehensive testing across varying power caps allowed us to accurately measure and optimize for the Energy-Delay Product (EDP), ensuring real-world applicability and significant improvements in sustainable computing practices.
