Energy: A New Criteria for Performances in Large Scale Distributed Systems

Part 2: Trends: Green ICT and Virtual MachinesInternational audienceIn the framework of the workshop “Performance Evaluation of Computer and Communication Systems: Milestones and Future Challenges”, this paper proposes to address the emerging criteria of energy. Used since a long time in embedded systems where battery operated devices needed a careful handling, the energy metric is taking a large momentum in the last years on large scale systems where thousands of nodes collaborate to serve high end infrastructures like web servers, clouds and grids
