National Initiatives

INRIA ADTs

Aladdin (A LArge-scale Distributed Deployable INfrastructure) is an INRIA Technological Development Action. It is a management structure for Grid'5000. We participate in this initiative. The goal of this action is to ensure the development of Grid'5000 by providing funding for engineers and training and some parts of the hardware.

SimGrid for human beings is another INRIA Technological Development Action, aiming at providing engineering manpower to the SimG rid project to improve the documentation, provide stock implementations of classical algorithms in order to ease its usage by the users. The results of this actions are described in Section  6.3.1 .

INRIA AEs

Héméra is an INRIA Large Wingspan project, started in 2010, that aims at demonstrating ambitious up-scaling techniques for large scale distributed computing by carrying out several dimensioning experiments on the Grid'5000 infrastructure, at animating the scientific community around Grid'5000 and at enlarging the Grid'5000 community by helping newcomers to make use of Grid'5000.

Within that project, Martin Quinson, Lucas Nussbaum and Stéphane Genaud lead three working groups, respectively on simulating large-scale facilities, on conducting large and complex experimentations on real platforms, and on designing scientific applications for scalability.

CNRS initiatives, GDR-ASR and specific initiatives

We participate at numerous national initiatives. In the GDR-ASR (architecture, systems, and networks) we take part in RGE action (Réseau Grand Est) and in the Embedded Pole . The finances of RGE, led by Stéphane Vialle at SUPÉLEC, are provided by the GDR ASR of CNRS and maintained by AlGorille. The RGE action organizes three meetings per year, and usually gathers 40-45 people per meeting.

We also participate to the animation of the GDR-ASR as a whole.

ANR Initiatives

Martin Quinson is the principal investigator of one project of the ARPEGE call from the ANR (french funding agency), called USS-SimGrid (Ultra Scalable Simulation with SimGrid). It aims at improving the scalability of the SimG rid simulator to allow its use in Peer-to-Peer research in addition of Grid Computing research. The challenges to tackle include models being more scalable at the eventual price of slightly reduced accuracy, automatic instantiation of these models, tools to conduct experiments campaigns, as well as a partial parallelization of the simulator tool.

As project leading team, we are involved in most parts of this project, which allows the improvement of our tool even further and set it as the reference in its domain (see Sections 6.3.1 through 6.3.6 ).

Bilateral Collaborations

With Jacques M. Bahi from the University of Franche-Comté, we work on the design and implementation of a decentralized load-balancing algorithm which works with dynamical networks. In such a context, we consider that the nodes are always available but the links between them may be intermittent. According to the load-balancing task, this is a rather difficult context of use. Our algorithm is based on asynchronous diffusion.

Lucas Nussbaum and Martin Quinson are participating to a research effort lead by F. Suter from the Computing Center of IN2P3. This project is jointly funded by CNRS' Institut des Grilles and INRIA 's ADT Aladdin in a program that aims at bridging the production grids and distributed systems research communities. The overall goal of the project is to explore ways to enable the scientific study and the evaluation of improvements in the context of the gLite grid middleware. This project was granted 5000 euros for 2010-2011.
