Abstract
The share-everything PDES (Parallel Discrete Event Simulation) paradigm is based on fully sharing the possibility to process any individual event across concurrent threads, rather than binding Logical Processes (LPs) and their events to threads. It allows concentrating, at any time, the computing power---the CPU-cores on board of a shared-memory machine---towards the unprocessed events that stand closest to the current commit horizon of the simulation run. This fruitfully biases the delivery of the computing power towards the hot portion of the model execution trajectory. In this article we present an innovative share-everything PDES system that provides (1) fully non-blocking coordination of the threads when accessing shared data structures and (2) fully speculative processing capabilities---Time Warp style processing---of the events. As we show via an experimental study, our proposal can cope with hard workloads where both classical Time Warp systems---based on LPs to threads binding---and previous share-everything proposal---not able to exploit fully speculative processing of the events---tend to fail in delivering adequate performance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
