The IN'Tech technology watch club, led by Inria and the association Grenoble Isère Logiciel (GRILOG), is organising a half-day of forums between researchers and industrial operators on "Green IT", technologies and computer services integrating energy and environmental constraints into their design, operation or applications.

  • Date : 8/06/2010
  • Place : Inria Grenoble - Rhône-Alpes, Montbonnot

Welcome from 1:30 p.m.


2:00 p.m. - 2:15 p.m.
By Philippe Broun, Inria, and James Crowley, Grenoble INP/GRILOG


2:15 p.m. - 2:45 p.m.
By Laurent Lefèvre RESO project-team/Inria and Anne-Céline Lamballe, Technology Transfer and Innovation department - Inria

Plenary sessions

2:45 p.m. ICT - unprecedented waste
Jez Wain, system architect, Group Bull

The presentation sets out the current state of data centres and indicates the sources of the main inefficiencies. It looks at potential improvements and discusses the difficulties of measuring the efficiency of a computer room.

3:15 p.m. Green Data Center
Frédéric Dulac, EOLAS

3:45 p.m. Introductions of demonstrations, forums and exchanges


4:00 p.m. Discovery of demonstrations, forums and exchanges

  • Green IT (Frédéric Bordage, more than 30,000 professionals visiting each month, is the site of reference for Green IT and sustainable ICT in France. The contributors of are all specialists in the field who share their thoughts and discoveries with the other members of the community. Our objective is to accelerate the dissemination of knowledge on the subject to help companies and individuals to reduce the environmental footprint of information and communication technologies.
  • Eco-ICT and responsible office automation (Laurent Alliod, DotRiver)DotRiver will show you how to work in good conditions with workstations that are more than five years old in order to prolong the useful life of PCs and thus avoid computer waste. The eco-innovative solution developed by DotRiver with open source software facilitates remote work and reinforces data security without putting a complex architecture into place. DotRiver is the only computer manufacturer to be supported by Ademe (French Agency for the Environment and Energy Control).
  • Energy efficiency for large scale Distributed Systems (A.C. Orgerie and M. Dias de Assuncao Inria project-team RESO)Distributed systems (grids, clouds) represent a significant, ever-growing fraction of global electricity consumption. This demonstration presents a software infrastructure that integrates energy-saving policies to regulate and control this consumption on an experimental platform of 150 nodes with continuously measured electricity consumption. Energy-saving policies are based on the extinction of unused nodes, aggregation and prediction of use. The software environment that we have developed also allows us to see the real-time impact of decisions made by our resource manager on electricity consumption.

Plenary talks

5:00 p.m. HOMES project
Didier Pellegrin, Schneider Electric

HOMES (Habitat and optimised building for control of energy and services) defines new architectures for the control and distribution of energy in buildings, integrating innovative technologies for sensors, control and power in order to market products and solutions necessary for better energy efficiency and permit the development of new services. The implementation of this active control requires multiple innovations: new technologies (for example, for sensors, energy stand-alone systems) as well as a system approach for the various functions of the building, an approach in which software holds an important place.

5:30 p.m. Impacts of computer science: resources, energy, waste; what do life cycle analyses tell us?
Françoise Berthoud (ECOINFO/CNRS)

The energy consumed in the usage phase of information and communication technologies is only one of the many aspects of the overall impact of the electronics industry throughout the life cycle of such equipment. I will highlight some life cycle analysis results and show why an environmental approach should not be limited to reducing the energy consumed in the usage phase.

Closing of the seminar
