ACI Globalisation des Ressources Informatiques et des Données

The Paris Project-Team is deeply involved in national initiatives related to the Grid. An initiative was launched by the Ministry of Research through the ACI program (Action Concertée Incitative). The ACI GRID (for Globalisation des Ressources Informatiques et des Données) aims at fostering French research activities in the area of Grid computing by providing financial support to the best research groups. The ACI GRID initiative was launched in 2001 and issued three calls for proposal (one every year). The Paris Project-Team submitted proposals for each of them. The following paragraphs present an overview of the projects funded by the ACI GRID in which the project-team is involved.


Participants : Alexandre Denis, Yvon Jégou, Jean-Louis Pazat, Christian Pérez, Thierry Priol, André Ribes.

The goal of this project is to promote a programming model for computing Grids. This model should combine both parallel programming and distributed programming models. It is based on the concept of distributed objects and software components for distributed programming. This project also aims at designing and experimenting a high-performance communication software framework, enabling both efficient communication between objects or components, and parallel programming. This 2-year project, coordinated by the Paris Project-Team, ends November 2003. The other partners are the Runtime Project-Team in Bordeaux, the Jacquard Project-Team in Lille, and the Oasis Project-Team in Sophia-Antipolis.

ACI GRID HydroGrid

Participants : Christian Pérez, André Ribes.

The HydroGrid project is a 3-year multidisciplinary project, started in September 2002. It aims at modeling and simulating fluid and solute transport in subsurface geological media using a multiphysic approach. Such multiphysic numerical simulation involve code featuring different languages and communication libraries (FORTRAN, Mpi, OpenMP, etc.), to be run on a commun computational Grid. Therefore, the project relies on the results of the ACI GRID RMI project. A strong point of the HydroGrid project is to group together teams with different areas of expertise (from applications, scientific computing and computer science). The partners are the Paris, Aladin and Estime Project-Teams at Irisa, the Hydrodynamique et Transferts en Milieux Poreux Team (IMFS Strasbourg) and the Transferts physiques et chimiques Team (Géosciences Rennes).


Participants : Gabriel Antoniu, Luc Bougé, Mathieu Jan, Thierry Priol.

This project gathers together the national research communities interested in large-scale data management. This includes communities involved in grid computing, operating systems, distributed systems and databases. The projects aims at understanding the common research issues and at defining a common terminology. An important goal of the project is encourage the emergence of software prototypes resulting from collaboration efforts of these communities.

The setup of the GDS Project of the ACI MD, coordinated by the Paris project-team, in collaboration with the ReMaP/GRAAL and REGAL Research Groups, is a result of the discussions that took place within the framework provided by DataGRAAL. The DataGRAAL community is the initiator of a project for a Spring School on large-scale data management (DRUIDE 2004), which will take place in May 2004 at Port-aux-Rocs (Le Croisic, Brittany). Gabriel Antoniu chairs the Program Committee and the Organizing Committee of this school. The project started in November 2002 and will end in November 2004. Gabriel Antoniu is local correspondent of DataGRAAL for the Paris Project-Team.


Participants : Jean-Louis Pazat, Christian Pérez.

Jean-Louis Pazat is at the head of the GRID2 project. At many as 10 laboratories from various parts of France are involved in this 150,000-Euro project granted by the Ministry of Research for 3 years. Christian Pérez is in charge of the Run-Time System and Middleware Working Group. The objective of this project is to federate the Computing GRID research community by organizing meetings between researchers, teaching for young researchers and by achieving information dissemination.

GRID2 is divided in the following working groups: (1) Software architecture and languages; (2) Run-time systems and middleware; (3) Algorithms and models; (4) Algorithms and high performance applications. This project has organized a Winter School on Grid Computing in Aussois in December 2002 and two workshops during the RenPar Conference in 2002 and 2003. A number of Hands-On Days have taken place this year, enabling researcher to gain practical experience of topics such as JXTA, CORBA, numerical computing, etc.


Participants : Alexandre Denis, Christian Pérez.

Alta is a 2-year joint project funded by the ACI GRID of the French Ministry of Research, in cooperation with the Inria Cooperative Research Initiatives. The Paris Project-Team coordinates the project. It also involves Runtime Project-Team in Bordeaux, and the Distribution and Parallelism Team in Lille. It aims at studying the impact of tolerant loss-control in the context of asynchronous iterative algorithm. An objective is to define and to implement a dedicated API.

ACI GRID Core Grid

Participant : Thierry Priol.

This project ( aims at helping the Paris Project-Team to prepare a Network Of Excellence proposal in the area of Grid and Peer-to-Peer Computing. Four European meetings were organized in 2003 and supported by this program: Rennes, April 15-16; Paris, July 15-16; Klagenfurt, August 27; Venice, September 1. These meetings led to the redaction of the Core Grid proposal that was submitted to the 2nd Call (October 15) of the IST Program (Framework Programme 6, European Commission) under Strategic Objective Grid-based systems for Complex Problems Solving.


Participant : Yvon Jégou.

GRID5000 is a nation-wide initiative to build a research platform (ca. 5000 processors) for Grid computing. This large-scale distributed platform will enable experimentations on operating systems, middlewares, and communications libraries by the computer-science research community in France. In 2003, the Paris Project-Team submitted a proposal for building a GRID5000 node in Rennes. The project has been selected by the French Ministry of Research (ACI GRID) to be one of the 7 initial nodes of the Grid5000 Computing Infrastructure and received a three-year grant of 200 kEuros. The integration of the first 66 processor boards (dual Xeon) to the Paris cluster (50 PC and Xserve dual-processor nodes) has been initiated during November 2003.

ACI Masses de Données

The Paris project-team is involved in the ACI MD (for Masses de Données). It aims at fostering research activities in the area of large-scale data management, including Grid computing. The first call for proposal was issued in 2003. The following paragraphs give a short overview of the project-team involvement in this initiative.


Participants : Gabriel Antoniu, Luc Bougé, Mathieu Jan, Sébastien Monnet, Thierry Priol.

The GDS Project of the ACI MD gathers 3 research teams: Paris (Irisa), REGAL (LIP6) and ReMaP/GRAAL (LIP). The main goal of this project is to specify, design, implement and evaluate a data sharing service for mutable data and integrate it into the DIET ASP environment developed by ReMaP/GRAAL. This service will be built using the generic JuxMem platform for peer-to-peer data management (currently under development within the Paris project-team, see section  6.3.2). JuxMem will serve to implement and compare multiple replication and data consistency strategies defined together by the Paris and REGAL research groups. The project started in September 2003 and will end in September 2006. It is coordinated by Gabriel Antoniu (Paris). Project site:


Participant : Yvon Jégou.

The main objective of the ACI MD MDP2P project is to provide high-level services for managing text and multimedia data in large-scale P2P systems. The Paris Project-Team contributes for the development of DSM-based (Mome and Kerrighed) data management techniques on clusters of clusters for large-scale multimedia indexing.


Participants : Gabriel Antoniu, Luc Bougé, Mathieu Jan, Sébastien Monnet, Thierry Priol.

The Data Grid Explorer (GdX) Project aims to implement a large-scale emulation tool for the communities of a) distributed operating systems, b) networks, and c) the users of Grid or P2P systems. This large-scale emulator consists of a database of experimental conditions, a large cluster of 1000 PCs, and tools to control and analyze experiments. The project includes studies concerning the instrument itself, and others that make use of the instrument. The GDS project of the ACI MD, coordinated by Paris, is partner of GdX, as a user project. The project started in September 2003 and will end in September 2006. Gabriel Antoniu is local correspondent of GdX for the Paris Project-Team.
