Abstract
Single-ISA heterogeneous multicore architectures promise to deliver plenty of cores with varying complexity, speed and performance in the near future. Virtualization enables multiple operating systems to run concurrently as distinct, independent guest domains, thereby reducing core idle time and maximizing throughput. This paper seeks to identify a heuristic that can aid in intelligently scheduling these virtualized workloads to maximize performance while reducing power consumption. We propose that the controlling domain in a Virtual MachineMonitor or hypervisor is relatively insensitive to changes in core frequency, and thus scheduling it on a slower core saves power while only slightly affecting guest domain performance. We test and validate our hypothesis and further propose a metric, the Combined Usage of a domain, to assist in future energy-efficient scheduling. Our preliminary findings show that the Combined Usage metric can be used as a starting point to gauge the sensitivity of a guest domain to variations in the controlling domain's frequency.

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
