Abstract

fetched live from OpenAlex

A promising avenue to control energy-related costs in enterprise data centers is to investigate power-aware resource management strategies. Mechanisms to accurately capture energy consumption in data centers include source and machine code instruction analysis, kernel sensors, system call monitors and per-VM metering techniques. Though very accurate, these approaches are highly invasive, requiring modifications to software or hardware, and introduce an observer effect that can adversely impact performance. Perhaps most important, results obtained from these approaches require refinement before they can actually be used for management decisions that must strike a balance between costs, SLOs and SLAs. Using existing instrumentation at a rack's PDU provides sufficient granularity to determine the true energy consumption of servers in a non-intrusive way. We show that by leveraging existing instrumentation at a rack's PDU, profiling the type of resource (e.g., CPU, memory, disk, network) a process is using on a given server is not only possible, but highly accurate despite the anticipated signal noise from other servers on a rack's power circuit. This provides a better foundation and allows us to forecast and manage energy demands in data centers.

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.
