Two Modified Multicast Algorithms for Two Dimensional Mesh and Torus Networks
Bibliographic record
Abstract
Multicast is message propagation from a source node to a number of destination nodes. Multicast could become the bottleneck for the performance of processes and systems. The main parameters for evaluating a multicast are time and traffic. Optimizing multicast time and traffic is proven to be NP-hard. In this paper, we propose improvements on two tree based multicast algorithms, PAIR and DIAG, in 2D mesh and torus networks. We prove that MDIAG generates optimal or optimal plus one multicast time in 2D meshes. MDIAG has lower complexity than DIAG, but might generate more traffic. MPAIR generates the least traffic, has the same complexity as PAIR and better complexity than DIAG, but might generate more time. The average time generated by both algorithms in a 2D torus is almost half the average time generated in a 2D mesh for the same algorithm. The average traffic generated by both algorithms in a 2D torus is less than the average traffic generated in a 2D mesh in most cases for the same algorithm. Extensive simulations of the algorithms show that they perform better than existing ones.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
