Abstract
The neighbourhood broadcasting problem in an interconnection network is defined as sending a fixed sized message from the source node to all its neighbours in a single-port model. Previously, this problem has been studied for several interconnection networks including the hypercube and the star. The objective of such works has been to minimize the total number of steps required for the neighbourhood broadcasting algorithms. Here, we first use a general neighbourhood broadcasting scheme to develop a neighbourhood broadcasting algorithm for the star interconnection network that is asymptotically optimal, conceptually simple, and easy to implement since routing for all nodes involved is uniform. It uses the cycle structures of the star graph as well as the standard technique of recursive doubling. We then show that the scheme for the star network is general enough to be applied to a broader family of interconnection networks such as the pancake interconnection network for which no previous neighbourhood broadcasting algorithm is known, resulting in asymptotically optimal algorithms. Finally, we use this scheme to develop neighbourhood broadcasting algorithms for multiple messages for several interconnection networks.

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
