Abstract

fetched live from OpenAlex

Clouds which continue to garner interest from practitioners in industry and academia require effective energy aware resource managers to leverage processing power of underlying resources while minimizing energy consumption in global data centers. This thesis proposes several energy aware resource management techniques that can effectively perform matchmaking and scheduling of MapReduce jobs each of which is characterized by a Service Level Agreement (SLA) that includes a client specified earliest start time, execution time and a deadline with the objective of minimizing energy consumption. Techniques are proposed for both batch workloads and open systems subject to continuous job arrivals. Simulation based experimental results presented in this thesis demonstrate the effectiveness of the proposed energy aware resource management techniques compared to alternative resource management techniques that do not consider energy consumption in task allocation and scheduling decisions.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
