Abstract
Intermittent hardware faults are hard to diagnose as they occur non-deterministically at the same location. Hardware-only diagnosis techniques incur significant power and area overheads. On the other hand, software-only diagnosis techniques have low power and area overheads, but have limited visibility into many micro-architectural structures and hence cannot diagnose faults in them. To overcome these limitations, we propose a hardware-software integrated framework for diagnosing intermittent faults. The hardware part of our framework, called SCRIBE continuously records the resource usage information of every instruction in the processor, and exposes it to the software layer. SCRIBE incurs a performance overhead of 12% and power overhead of 9%, on average. The software part of our framework is called SIED and uses backtracking from the program's crash dump to find the faulty micro-architectural resource. Our technique has an average accuracy of 84% in diagnosing the faulty resource, which in turn enables fine-grained deconfiguration with less than 2% performance loss after deconfiguration.

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
