Data Center AI Workload Power Profiling

Methods for measuring generative AI workload power consumption and scaling to whole-facility energy demand for infrastructure planning.

Overview

Paper: "Measurement of Generative AI Workload Power Profiles for Whole-Facility Data Center Infrastructure Planning" (arXiv: 2604.07345v1, April 2026)

Key contribution: Bridges the gap between high-resolution workload power measurements and whole-facility energy demand estimation.

Workload Power Measurement

Benchmark-Based Profiling

Use standardized benchmarks for reproducible profiling:

• MLCommons benchmarks for model training and fine-tuning
• vLLM benchmarks for inference workloads

Measurement Setup

• NVIDIA H100 GPUs (representative hardware)
• 0.1-second resolution power sampling
• Capture temporal fluctuations during training/fine-tuning/inference

Power Profile Components

1. GPU power - Primary computation energy
2. Memory power - Data movement energy
3. Cooling overhead - Thermal management energy
4. Auxiliary systems - Network, storage, management

Whole-Facility Energy Modeling

Bottom-Up Event-Driven Model

Scale workload profiles to facility level:

1. Aggregate individual workload profiles
2. Model temporal distribution of user requests
3. Include infrastructure overhead (cooling, power distribution)
4. Capture realistic fluctuations

Energy Profile Characteristics

• Temporal fluctuations - Driven by AI workloads and user behavior
• Peak demand estimation - Maximum power draw periods
• Average demand - Baseline energy consumption
• Demand variability - Range of power fluctuations

Infrastructure Planning Applications

Grid Connection Planning

Use energy profiles to determine:

• Required power capacity from grid
• Peak demand management strategies
• Grid stability considerations

On-Site Energy Generation

Evaluate options:

• Solar/wind capacity sizing
• Battery storage requirements
• Backup generation sizing

Distributed Microgrids

Design resilient power infrastructure:

• Local generation capacity
• Load balancing strategies
• Failover mechanisms

Implementation Approach

Data Collection

# Power measurement workflow
1. Configure H100 GPU measurement setup
2. Run MLCommons/vLLM benchmark workloads
3. Record power at 0.1s resolution
4. Capture full workload duration
5. Export power profile data

Scaling Methodology

Workload Power → Facility Energy:
1. Sum individual workload profiles
2. Apply temporal user-behavior model
3. Add infrastructure overhead factors
4. Generate facility-level time series

Key Metrics

Practical Applications

• New data center design - Size infrastructure for AI workloads
• Capacity expansion - Plan for additional GPU deployments
• Cost estimation - Predict energy costs for AI operations
• Sustainability - Evaluate renewable energy integration
