Abstract

fetched live from OpenAlex

The neighbourhood load balancing problem considers a network along with a distribution of tasks over its nodes. The aim is to minimize discrepancy which is the difference between the maximum and the minimum load. This is done by a distributed process that exchanges load between neighbouring nodes. One distinguishes between the continuous model - where tasks can be split arbitrarily - and the more practical discrete model in which tasks are atomic. The former has been comprehensively studied in early results [20, 57, 29]. In the latter model, various algorithms have been developed and analyzed [10, 9, 27, 28, 41, 39, 44, 57, 62, 64]. Nevertheless, several aspects are yet to be explored, such as devising new discrete algorithms, and generalizing or tightening the existing analyses. We study the problem of discrete neighbourhood load balancing. We propose a new approach that can transform continuous load balancing algorithms into deterministic or randomized discrete versions. Despite its simplicity, the proposed approach works in quite general settings (arbitrary network topology, weighted tasks and heterogeneous processors) and in many cases achieves improved discrepancy bounds. We also study the usage of rotor-router walks - deterministic analogue of random walks - for discrete load balancing, and in particular, derandomization of existing randomized approaches. After that, we obtain discrepancy bounds for deterministic and randomized discrete second-order processes [57], where the amount of load transferred in each round depends both on the current load distribution and the amount of load transferred in the previous round. In second-order processes a node may attempt to send out more load than its available load. To address this issue, we provide bounds on the minimum load of any node which is sufficient to prevent such conditions.

Full frame distilled prediction

Teacher imitation

Not 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.
