COST Action Meeting

On May 8th, the COST Action IC0804 on Energy Efficiency in Large Scale Distributed Systems ( is organizing an open meeting before the e-Energy conference.

The participation to this meeting is free of charge, and open to the community.

The program will be delivered soon. Normally, the Working Groups and the Focus Groups of the Action (see details on are meeting and they discuss various points with support of dedicated agenda.

If you want to participate to this meeting, please contact the Chair of the Action (Jean-Marc Pierson, pierson at or the WG and FG Chairs so as to organize the logistics. If you want to have more information please contact the Chair of the Action.

Technical Program

Tuesday, May 8th (Venue)

8:00   Welcome to participants / Registration (free)
8:15   Introduction by Jean-Marc Pierson, Chair of the Action (15mn)                   
8:30  Working Group 1: State of the art and continuous learning of hardware adaptation possibilities

Presentation of the WG1 Brochure on “Hardware Leverages for Energy Efficiency in Large Scale Distributed Systems”, Georges Da Costa, Davide Careglio, WG1 Chairs (5mn) Round Table on "What's the point of working on software when hardware improves so much!”
In this round table, the aim is two-fold, to discuss about the, sometimes, mismatching between software and hardware improvements, and to analyze solutions where software improves hardware.

  • Babak Falsafi, EPFL, Ecole Polytechnique Fédérale de Lausanne
  • Wolfgang Christmann, christmann informationstechnik + medien GmbH & Co. KG
  • Gabriele Cocco, University of Pisa: Energy consumption of heterogenous parallel algorithms
10:30 Coffee Break     
11:00 Working Group 2: Characterization of energy consumption and energy efficiency

Introduction by Alberto E. Garcia, Karin A. Hummel, WG2 Chairs
Round Table on "Monitoring of energy consumption - are our tools sufficient?"

The round table discussion will focus on the quality and limits of existing monitoring approaches and tools, at proposing requirements for monitoring tools, and at identifying open research questions.


  • Cécile Germain-Renaud, U. Paris Sud, France : "The Green Computing Observatory" - On monitoring from a perspective of data organization and description
  • Torsten Braun, University of Bern, Switzerland: On HW and SW approaches to monitor WMNs and WSNs
  • Davide Morelli, University of Pisa, Italy: Energon: a framework for measurement and analysis of energy consumption of software
12:30 Lunch     
14:30 Working Group 3: Adaptive actions for distributed systems
WG3 news: Laurent Lefèvre and Hermann De Meer, WG3 Chairs (5 mn)
Round Table on “Wired / wireless Green Networks : possible or needed convergence of approaches ?”
This round table will address the question of the differences (or not) about dealing with energy efficiency in wired and wireless networks.
  • Laurent Lefèvre, INRIA France
  • Andrea Passarella, Univ. of Pisa
16:00 Coffee Break     
16:30 Working Group 4: Characterization of performance-energy saving trade-off
WG4 introduction: Rastin Pries and Tuan A. Trinh, WG4 Chairs (10 mn)
Round Table on "Metrics for End-to-End Energy Efficiency"
In this round table, we want to discuss whether end-to-end energy efficiency is feasible and what kind of metrics can be set up for it. Is it possible to have something similar to QoE with the Mean Opinion Score based on e.g. delay, loss, jitter, and what are the influence parameters for end-to-end energy efficiency?
  • Paul Kuehn, University of Stuttgart, “Energy-Efficiency of User and Network Nodes”
  • Franco Davoli, University of Genoa, "Connection-wise energy efficiency: measuring power consumption of TCP and of nodes along the path"
  • Pedro Reviriego Vasallo, University Antonio de Nebrija, Madrid, " Energy efficiency dependency on traffic load is here to stay. What are the implications for metrics and measurements?"
  • Markus Fiedler, Blekinge Institute of Technology, Karlskrona, “Hurry up -- quick end-to-end delivery saves energy”
