Abstract
In this paper, we use experimental measurements to calibrate and validate a discrete-event simulator for dynamic speed scaling systems. The experimental implementation work is carried out in an Ubuntu Linux environment using a quad-core 2.3 GHz Intel i7 processor with the Ivy Bridge micro-architecture. Our implementation provides fine-grain user-level control of process execution, and uses the Running-Average Power Limit (RAPL) Machine Specific Registers (MSRs) to track energy usage. Through careful micro-benchmarking experiments, we determine the power consumption for each of the 12 discrete speeds supported by the processor, while also quantifying the costs of context switches and CPU speed changes. Finally, we use our suitably-parameterized speed scaling simulator to evaluate three different CPU speed scaling algorithms from the literature on simple batch workloads. To the best of our knowledge, our paper provides the first direct comparison of these speed scaling strategies with realistic system costs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
