The Green Grid5000: Instrumenting a Grid with Energy Sensors

International audienceTargeting mostly application performance, distributed systems have constantly increased in size and computing power of their resources. The power supply requirements of these systems have increased in a similar fashion, which has raised concerns about the energy they consume. This paper presents the Green Grid'5000 approach, a large-scale energy-sensing infrastructure with software components that allow users to precisely measure and understand the energy usage of their system. It also discusses a set of use-cases describing how an energy instrumented platform can be utilised by various categories of users, including administrators, Grid component designers, and distributed application end-users
