Abstract

fetched live from OpenAlex

In this paper, we address the problem of virtual machine (VM) placement in an InterCloud with regard to the reduction of carbon footprint in such computing environment. In order to minimize the data center Greenhouse Gas (GhG) emissions, this paper proposes a new mathematical formulation, where the placement approach is stated as a mixed integer programming problem which aims at minimizing the overall carbon footprint of the InterCloud. The proposed formulation presents an accurate carbon footprint evaluation based on joint optimization techniques, such as workload consolidation and cooling efficiency maximization, while considering the greenness of the data centers and the dynamic behavior of the IT equipment cooling fans. Simulation results showed that our model leads to optimal configurations with minimal carbon footprint in the InterCloud environment.

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.
