Abstract
Recent advances in die-stacking and 2.5D chip integration technologies introduce in-package network heterogeneities that can complicate the interconnect design. Integrating chiplets over a silicon interposer offers new opportunities of optimizing interposer topologies. However, limited by the capability of existing network-on-chip (NoC) simulators, the full potential of the interposer-based NoCs has not been exploited. In this paper, we address the shortfalls of prior NoC designs and present a new family of chiplet topologies called Kite. Kite topologies better utilize the diverse networking and frequency domains existing in new interposer systems and outperform the prior chiplet topology proposals. Kite decreased synthetic traffic latency by 7% and improved the maximum throughput by 17% on average versus Double Butterfly and Butter Donut, two previous proposals developed using less accurate modeling.

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
