Energy Efficiency & Sustainability
Optimizing 100kW+ Racks: Facilities, Hardware, and Software Synergy.
The Core Operational Constraint
Energy efficiency in 2026 is no longer a "nice-to-have" but a core requirement driven by massive power densities and strict regulations like the EU Data Centre Energy Efficiency Package. We implement a coordinated strategy across facilities, hardware, and software to reduce your carbon footprint and TCO.
1. Advanced Cooling Infrastructure
Direct Liquid Cooling (DLC)
Transitioning to warm-water cooling (30–40°C) eliminates the need for energy-intensive chillers. Cold plates attached directly to CPUs/GPUs remove up to 95% of heat at the source.
Heat Reuse & Circularity
Modern designs channel waste heat (70–90°C via heat pumps) into local building heating or city networks. This turns a "waste" product into a valuable resource for urban infrastructure.
2. Energy-Aware Job Scheduling
We transition your Resource Manager (Slurm/PBS) to power-aware algorithms that optimize for energy, not just speed:
- Dynamic Power Capping: Adjusting CPU/GPU clock speeds (DVFS) in real-time to stay below facility thresholds.
- Green Credits: Prioritizing jobs that run during off-peak hours when renewable energy is abundant.
- Predictive Thermal Twins: Using AI to anticipate thermal hotspots and optimize job placement.
3. Real-Time Sustainability Analysis
| Category | Tools & Metrics | Optimization Goal |
|---|---|---|
| Facility Level | PUE (Power Usage Effectiveness) | Target PUE below 1.1; identify air recirculation losses. |
| Node Level | RAPL (Running Average Power Limit) | Limit power draw of DRAM and CPU per task. |
| Job Level | Energy-per-Simulation (Joules) | Assess total energy cost per scientific insight. |
| System Level | Digital Twin Dashboards | Anticipate thermal behavior and prevent throttling. |
4. Communication-Avoiding Algorithms
Inefficient code wastes energy. We assist in refactoring software for the green era:
- Mixed-Precision: Reducing energy cost per op by using FP16/BF16/FP8 where 64-bit isn't required.
- Data Locality: Since moving data across the network costs more than processing it, we focus on local-memory-heavy algorithms.
