Abstract
Graph partitioning is a long-standing research problem and has applications in various domains, such as data mining, scientific computing, VLSI design. For many years researchers have been focusing on improving the performance of graph partitioning using multi-core CPUs and accelerators like GPUs. However, efficient implementation of graph partitioning on GPU is a challenge. This is because graphs exhibit irregular behavior whereas GPUs follow SIMD execution patterns and GPUs have various resources and efficient utilization is the key to improving the performance.This paper aims to provide an efficient GPU based implementation of multi-level graph partitioning scheme. We provide GPU implementations of coarsening, partitioning, and refinement phases of the algorithm, to improve the overall performance of the graph partitioning scheme. We evaluated our implementation on various real-world datasets, and we observed a significant improvement in the performance when compared to the baseline METIS.

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
