Tools to analyse scheduling and energy efficiency
This proposal has been accepted as a session.
One Line Summary
Improving scheduler regression testing with a focus on energy efficiency
Abstract
The scheduler, by virtue of being in charge of placing tasks on various cpus, is ultimately responsible for the power state of these cpus.
While we have some benchmarks to measure scheduling performance, they focus on maximising throughput. There are currently no tools to help maintainers judge if a patch(set) improves or regresses energy consumption for a workload. This talk will introduce a new tool that can help with this – idlestat.
The goal of the talk is to get more ideas from the community on making idlestat more useful with a view to getting it merged in the kernel.

Biography
Amit is a Technical Lead for Power Management at Linaro. In this role, he’s getting an opportunity to make Linux power management somewhat architecture-agnostic. His previous jobs included stints at Canonical as an ARM kernel engineer and working on Power management for Nokia’s Maemo-based internet tablets. Prior to that he worked on a US defense contract that made him fall in love with the phrase “mobile self-healing wireless networks”.
Amit loves new cultural experiences resulting from his love for travel.
