Abstract

fetched live from OpenAlex

The use of CC-NUMA multiprocessors complicates the placement of physical memory pages. Memory closest to a processor provides the best access time, but optimal memory page placement is a difficult problem with process movement, multiple processes requiring access to the same physical memory page, and application behavior changing over execution time. We use dynamic page placement to move memory pages where needed for the database benchmark TPC-C executing on a four node CC-NUMA multiprocessor. Dynamic page placement achieves local memory accesses up to 73% of the time instead of the static page placement results of 34% locality achieved with first touch and 25% with round robin. This can result in a 17% improvement in performance.

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.
