Abstract
In this paper, we report on a new CPU-architecture extension proposal, named Advanced Synchronization Facility (ASF), which is geared toward accelerating and easing lock-free programming and software transactional memory (STM). We present an initial performance simulation and usability study of ASF’s application to a lock-free data structure (a singly linked list) and to accelerating a state-of-the-art STM system, TinySTM. Our results indicate that ASF can significantly increase the throughput and scaling behavior of these workloads: Single-thread performance increased by up to 15 %, and the factor of scaling to eight CPUs increased by up to 20 %.

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
