Poster: DVFS management in real-processors

We develop two simple interval-based models for dynamic superscalar processors. These models allow us to: i) predict with great accuracy performance and power consumption under various frequency and voltage combinations and ii) implement targeted DVFS ...

The limited utility of voltage scaling in nano-scale technologies has led high-performance processors to rely increasingly on frequency scaling for power management. However, frequency scaling provides only a linear dynamic power reduction.

In this ...

Main memory is responsible for a large and increasing fraction of the energy consumed by servers. Prior work has focused on exploiting DRAM low-power states to conserve energy. However, these states require entire DRAM ranks to be idled, which is ...
