Abstract
Architectural complexity continues to grow as we consider the large design space of multiple cores, cache architectures, networks-on-chip (NoC) and memory controllers. Simulators are growing in complexity to reflect these system components. However, many full-system simulators fail to utilize the underlying hardware resources such as multiple cores; consequently, simulation times have grown significantly. Long turnaround times limit the range and depth of design space exploration. Communication has emerged as a first class design consideration and has led to significant research into NoCs. NoC is yet another component of the architecture that must be faithfully modeled in simulation. Here, we focus on accelerating NoC simulation through the use of sampling techniques. We propose NoCLabs and NoCPoint, two sampling methodologies utilizing statistical sampling theory and traffic phase behavior, respectively. Experimental results show that NoCLabs and NoCPoint estimate NoC performance with an average error of 7% while achieving one order of magnitude speedup.

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
