XtreemOS IP Project
Participants : Surbhi Chitre, Marko Obrovac, Jérôme Gallard, Yvon Jégou, Sylvain Jeuland, Peter Linnell, Sandrine L'Hermitte, Christine Morin, Thierry Priol, Thomas Ropars.
Christine Morin is the Scientific Coordinator (SCO) of the XtreemOS Integrated Project (IP) that addresses Strategic Objective 2.5.4 Advanced Grid Technologies, Systems and Services , Focus 3 on Network-centric Grid Operating Systems as described in the IST 2006 Work Programme. XtreemOS involves 19 academic and industrial partners from 7 European countries plus China. The XtreemOS project aims at the design, implementation, evaluation and distribution of an open source Grid operating system with native support for virtual organizations and capable of running on a wide range of underlying platforms, from clusters to mobiles. The approach we propose in this project is to investigate the construction of a new Grid OS, XtreemOS , based on the existing general-purpose OS Linux  . Yvon Jégou leads the WP4.3 Work-Package, aiming at setting up XtreemOS testbeds. The Grid'5000 experimental grid platform is used as a large-scale testbed by XtreemOS partners. Christine Morin leads WP1.1, Project management, WP2.1, Virtual Organization support in Linux, WP2.2 Federation management and WP5.3, Collaboration with other IST Grid-related projects. Thierry Priol is a member of the Scientific Advisory Committee .
S-Cube NoE Project
Participants : Françoise André, Erwan Daubert, Guillaume Gauvrit, André Lage, Nikos Parlavantzas, Jean-Louis Pazat, Chen Wang.
S-Cube is a European Network of Excellence in Software Services and Systems. Its goal is to establish an integrated, multidisciplinary, vibrant research community. This will enable Europe to lead the software-services revolution, thereby helping shape the software-service based Internet which is the backbone of our future interactive society.
We are now leader of the infrastructure workpackage which aims at defining specifications of the infrastructure for building adaptable and self-* service based applications.
In this area we are working on adaptation at the level of one single service (André Lage's PhD thesis) and on distributed and multilevel adaptation. The different phases of the adaptation process are studied: in his PhD thesis Guillaume Gauvrit focuses on the problem of the decision phase in a distributed and multi-levels context, whereas Erwan Daubert's thesis tackles the problem of the planification and implementation of adaptation actions for distributed heterogeneous Service-Oriented platforms. We are also investigating the use of non-conventional programming paradigms for service composition and execution (PhD thesis of Chen Wang).
IC0804 - Energy efficiency in large scale distributed systems
Participants : Françoise André, Jean-Louis Pazat.
This COST Action will propose realistic energy-efficient alternate solutions to share IT distributed resources. As large scale distributed systems gather and share more and more computing nodes and Storage resources, their energy consumption is exponentially increasing. While much effort is nowadays put into hardware specific solutions to lower energy consumptions, the need for a complementary approach is necessary at the distributed system level, i.e. middleware, network and applications. The Action will characterize the energy consumption and energy efficiencies of distributed applications.
