Abstract
QoS criteria in cloud computing require guarantees about application runtimes, even if CMP servers are shared among multiple parallel or serial applications. Performance of computation-intensive application depends significantly on memory performance and especially cache performance. Recent trends are toward configurable caches that can dynamically partition the cache among cores. Then, proper cache partitioning should consider the applications' different cache needs and their sensitivity towards insufficient cache space. We present a simple, yet effective and therefore practically feasible black-box model that describes application performance in dependence on allocated cache size and only needs three descriptive parameters. Learning these parameters can therefore be done with very few sample points. We demonstrate with the SPEC benchmarks that the model adequately describes application behavior and that curve fitting can accomplish very high accuracy, with mean relative error of 2.8% and maximum relative error of 17%.

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
