Explore how LLM embeddings revolutionize per-job power prediction, achieving higher accuracy than state-of-the-art methods.
The study's novel semantic retrieval model (SR) demonstrates a 15% reduction in Mean Absolute Error (MAE) for per-job power prediction compared to the current state-of-the-art baseline (UoPC). This significant improvement is primarily driven by gains in the high-volume, low-to-mid power consumption regions (250-500 W), where 40% of all jobs reside. The semantic approach, leveraging Large Language Model (LLM) embeddings of enriched job scripts, captures nuanced domain- and workflow-specific cues, leading to more accurate predictions without manual feature engineering. A similar trend is observed for runtime prediction, with a 12% reduction in mean runtime error.

Case Study: Solar Energy Integration
Our optimized energy-aware scheduling strategy successfully shifted 4.0 MWh of workload onto on-site solar generation during a 15-day study window. This was achieved without compromising job throughput; in fact, executed work slightly increased by 1.1%. The average wait time decreased from 26.4 hours to 23.8 hours, demonstrating improved efficiency. The FastSim simulator, enhanced for high fidelity and speed (1200x faster than real-time), was crucial for optimizing the scheduling parameters to maximize renewable energy utilization while balancing wait times.
The energy-aware scheduling algorithm leverages predicted power usage and real-time renewable energy availability to dynamically adjust job priorities within Slurm's multifactor priority framework. This lightweight heuristic approach avoids core scheduler modifications, making it practical for production deployment. The rigorous validation of the FastSim simulator against historical job traces ensures that simulation results accurately reflect real-world performance, providing a reliable framework for evaluating and optimizing new scheduling policies. The optimization process uses Optuna to maximize renewable power utilization, achieving a deliberate balance between minimizing job wait times and maximizing clean energy use.

Job-Submit Plugin Integration
Capture submission context and hand off to out-of-band predictor for power/runtime predictions. Returns immediately to avoid blocking slurmctld.
Inference Service Deployment
Embed submission context, retrieve nearest neighbors, and compute predictions. Write predictions back to Slurm-visible fields (e.g., job Comment).
SiteFactor Plugin Configuration
Polls and publishes external energy source data (e.g., 1-5 minute intervals). Reads predictions and energy signals to compute per-job priority adjustments.
Incremental Rollout & Tuning
Gradually increase SiteFactor weight. Periodically tune parameters on recent traces to ensure reproducibility and stability.
This blueprint outlines a Slurm-native deployment strategy utilizing existing plugin interfaces (Job-Submit and SiteFactor). The approach ensures that core scheduler modifications are avoided, mitigating risks and simplifying adoption. Predictions are generated by a lightweight inference service, which allows for fast, non-blocking operations. The system is designed for incremental rollout, enabling administrators to gradually increase the influence of energy-aware scheduling and periodically tune parameters based on real-world performance, ensuring stability and optimal results.
