Optimizing Energy Efficiency in HPC and AI with NVIDIA GPUs

In the realm of high-performance computing (HPC) and artificial intelligence (AI), energy efficiency is becoming increasingly crucial. As reported by the NVIDIA Technical Blog, Alan Gray, a Principal Developer Technology Engineer at NVIDIA, offers insights into optimizing energy and power efficiency for applications utilizing NVIDIA's latest technologies.

Balancing Performance and Energy Consumption

The traditional approach in computing has heavily focused on maximizing performance by reducing execution time. However, with the rising costs of energy and the growing environmental impact of data centers, developers are now prioritizing energy consumption in their strategies. Energy usage, which is the product of power and time, can be effectively managed by fine-tuning GPU settings and application configurations.

Target Audience

This initiative is particularly beneficial for HPC and AI developers, data center operators, and GPU programmers seeking to enhance energy efficiency alongside performance. It also holds value for researchers utilizing applications like GROMACS or AI inference models and IT teams aiming to cut down energy costs and environmental footprint.

Key Areas of Focus

Gray's session delves into several critical areas for optimizing energy and power efficiency on NVIDIA GPUs:

• Energy Optimization Introduction: Discussing the balance between performance and energy efficiency in HPC and AI.
• GPU Clock Frequency Tuning: Examining the impact of clock frequency adjustments on power consumption and runtime.
• Application Benchmarks: Sharing insights from energy optimization in workloads like GROMACS and TensorRT-LLM.
• Non-GPU Power Impact: Exploring energy consumption from CPUs, memory, and cooling systems, and strategies like Direct Liquid Cooling (DLC).
• Energy Efficiency on NVIDIA H100 and DGX A100: Analyzing energy-saving potential and the influence of non-GPU components on total power consumption.
• Application-Level Optimizations: Techniques for optimizing performance and energy efficiency at the application level.
• Holistic Data Center Energy Strategies: Comprehensive approaches to minimizing energy usage through hardware and software optimizations.
