Abstract
The power requirements of a single workload may vary depending on the program phase, or region. In order to monitor the power dissipation of the processor, multiple power models have been previously proposed. These models rely on the performance counters to estimate the power dissipation of the processor. To the best of our knowledge, this work is the first to investigate the effects of the value of the data being processed in the workload on power. It is shown that the power requirements of the processor correlates with the amount of bit-flips necessary to store a new value over the previous one and considering value locality can improve the power model of store performing instructions to up to 7%. This work shows the limitations of relying solely on performance counters and introduces the need to investigate the data flow of the workload in addition to the control flow, in order to achieve more precise power estimations.

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
