Abstract
Design and Implementation of K42's Dynamic Clustered Object Switching Mechanism Kevin Hui Master of Science Graduate Department of Computer Science University of Toronto 2000 Recent research efforts have investigated customizable operating systems, where the implementation of operating system services can be chosen to meet an application's performance or functionality requirements. This dissertation investigates the potential benefits of allowing the customization to be changed, on-the-fly, while the service is in use. By using a prototype implementation of the dynamic object switching layer in the K42 operating system, we explore the costs and benefits associated with dynamic customization. As an example, we showed how K42 can switch a (per-file) page cache from a centralized implementation to one distributed across the processors of a multiprocessor in order to adapt to changing access patterns. The ability to customize on-the-fly allows the implementation of a service to match the instantaneous demands on the service, avoiding the need to comprise a complex, catch-all implementation. It also facilitates live-swapping of system components in mission-critical systems where downtime is undesirable.

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
