The goal of the ECO-GRAPPE project is to design an operating system able to automatically manage the energy consumption of a cluster.

ECO-GRAPPE is funded by the French ANR research agency. The three partners involved are: EDF R&D, INRIA Rennes and Kerlabs, a spin-off of the PARIS project-team.

AutoCHEM ANR Project

This project aims at investigating and exploring an unconventional approach, based on chemical computing, to program complex computing infrastructures, such as Grids and real-time deeply-embedded systems. Chemical computing uses the chemical reaction metaphor to express the coordination of computations. This metaphor describes computation in terms of a chemical solution in which molecules (representing data) interact freely according to reaction rules. Chemical solutions are represented by multisets (data-structure that allows several occurrences of the same element). Computation proceeds by rewritings, which consume and produce new elements according to conditions and transformation rules.

In the framework of the ANR CLOUD project, we extend the XtreemOS Grid system in order to allow the use of virtual resources dynamically supplied from different IaaS clouds. This dynamic resource provisioning will make possible the grid extension in the event of high resources demand or when resources having specific characteristics are not available in the Grid.

We design and implement a service that automatically selects a given cloud in order to provide the missing resources in the grid (depending on the resources characteristics, depending of the cost of the virtual resources in different clouds…). In addition, we integrate in XtreemOS distributed operating system the mechanisms needed to dynamically add virtual resources in an XtreemOS Grid.
A first testbed based on an expanded XtreemOS system to take advantage of resources provided by an Open Nebula cloud will be implemented. We will provide tools to allow this test bed to be automatically deployed on the Grid’5000 infrastructure. All the developed software will be made available in open source to the research community, so that one can reproduce experiments.

We intend in a second phase to refine the first testbed so that it can be interfaced with the federation service developed as part of the Contrail European project. This will allow an XtreemOS Grid to make use of virtual resources provided by various clouds running different IaaS technologies (OpenNebula, OpenStack, AMZ EC2, any OCCI compliant IaaS cloud).

 The objective of the ASYST project (Adaptation dynamique des fonctionnalités d’un SYSTème d’exploitation large échelle) funded by the Brittany council is to provide a view of a distributed operating system as an assembly of services following the service-oriented paradigm. The motivation is to facilitate dynamically adapting operating systems to cope with their constantly changing environments.This project funds 50% of a PhD grant: Djawida Dib

Past Projects funded by Inria


The XtreemOS EASY ADT aimed at developing a set of tools and environments to ease the installation, con guration, deployment, experimentation and use of the XtreemOS Grid operating system and at providing support to the XtreemOS open source community. It funded two junior engineers.


We participated to the DAUM ADT which is coordinated by the Triskell Team. DAUM aimed at providing an integrated platform for distributed dynamically adaptable component based applications. DAUM unites and integrates results and software from the Triskell EPI and the Myriads team. More precisely, DAUM extends the Kevoree component framework designed by Triskell with adaptation mechanisms from the SAFDIS framework designed by Myriads.
