Abstract
The optimal power flow problem (OPF) has been of importance to power system operators for many decades. Being able to quickly determine optimal operating points and analyzing larger networks can lead to advantages for operators from reliability, stability, cost and market fairness perspectives. This work aims at achieving those ends by solving OPF problems by utilizing hardware acceleration capabilities of graphical processing units (GPUs). At present, nearly all desktop and laptop computers ship with general-purpose GPUs that can be harnessed to accelerate analysis. This work will present important concepts regarding effective use of GPUs as it pertains to OPF problems and illustrate the types of problems that stand to benefit most from their use. The benefits of GPU acceleration are demonstrated by implementing a predictor-corrector interior-point method with the majority of the computation offloaded onto a GPU. Experiments are used to validate the developments by analyzing well-known power systems.

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
