Unobtrusive power proportionality for HPC frameworks
Arka Bhattacharya, David Culler · 2014
Building power proportional High Performance Computing (HPC) clusters comprising of servers which are not power-proportional is a well-studied problem, and has the potential to provide large energy savings. However, a large emphasis on maintaining cluster uptime disincentivizes system administrators from deploying prior research techniques that introduce changes to existing software configurations, modify the existing cluster job management framework, change user job submission procedures, or fail in unpredictable ways due to frequent server power cycling[3].
