Abstract
This paper introduces Octopus<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup>, an open-source cycle-accurate cache system simulator with flexible interconnect models. Octopus meticulously simulates various cache system and interconnect components, including controllers, data arrays, coherence protocols, and arbiters. Being cycle-accurate enables Octopus to precisely model the behavior of target systems, while monitoring every memory request cycle by cycle. The design approach of Octopus distinguishes it from existing cache memory simulators, as it does not enforce a fixed memory system architecture but instead offers flexibility in configuring component connections and parameters, enabling simulation of diverse memory architectures. Moreover, the simulator provides two dual modes of operation, standalone and full-system simulation, which attains the best of both worlds benefits: fast simulations and high accuracy.

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
