Abstract
The industry trend of Chip Multiprocessors (CMPs) architecture is to move from 2D CMPs to 3D CMPs architecture which obtains higher performance, more reliability, reduced cache access latency, and increased cache bandwidth. Moreover, 3D CMP architectures have recently gained significant attention to tackle the increasing power consumption in single core processors. However, one key challenge in designing the 3D CMP is the thermal issue as a result of maximizing the throughput. The thermal hotspot causes performance degradation and reliability reduction in the 3D CMP. In this paper, a run-time task migration approach is proposed to balance the temperature and reduce the number of hotspots in the 3D CMP without any performance degradation. The proposed approach is divided into two algorithms that aim at maximizing the throughput on the 3D CMP while satisfying the peak temperature constraint. Experimental results on the PARSEC benchmarks show that the proposed architecture yields up to 60 % reduction in overall chip energy with just 17 % performance degradation on average over all the used workloads. The best energy saving was 72 % with a negligible performance degradation.

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
