Abstract

fetched live from OpenAlex

This paper presents two techniques for reducing the power consumed by database servers. Both techniques are intended primarily for transactional workloads on servers with memory-resident databases. The first technique is databasemanaged dynamic processor voltage and frequency scaling (DVFS). We show that a DBMS can exploit its knowledge of the workload and performance constraints to obtain power savings that are more than twice as large as the power savings achieved when DVFS is managed by the operating system. The second technique is rank-aware memory allocation, the goal of which is to power memory that the database system needs and avoid powering memory it does not need. We present experiments that show rank-aware allocation allows unneeded memory to move to low-power states, reducing memory power consumption.

Teacher imitation

Not 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.
