Abstract

fetched live from OpenAlex

The problem of identifying suitable conditions for the schedulability of (nonpreemptive) recurring tasks with deadlines is of great importance to real-time systems. In this paper, motivated by the problem of scheduling radar dwells, we show that scheduling problems of this nature show a sharp threshold behavior with respect to system utilization. Sharp thresholds are associated with phase transitions: When the utilization of a task set is less than a critical value, it can be scheduled almost surely and, when the utilization increases beyond the critical level, almost no task set can be scheduled. We make connections to work on random graphs to prove the sharp threshold behavior in the scheduling problem of interest. Using extensive experiments, we determine the threshold for the radar dwell scheduling problem and use it for performance optimization. The connections to random graph theory suggest new ways for understanding the average-case behavior of scheduling policies. These results emphasize the ease with which performance can be controlled in a variety of real-time systems.

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.
