MRSEI Fennec

FastEr NaNo-Characterisation

L’objectif du projet FENNEC de l’ANR-MRSEI est de faciliter le montage d’un projet pour l’appel DT-NMBP-08-2019 intitulé « Real-time nano-characterisation technologies (RIA) ». La caractérisation à l’échelle nanométrique permet d’avoir des informations uniques sur la structuration et les propriétés des matériaux et des dispositifs mais nécessite une expérience pointue dépendant des matériaux envisagés, des temps d’acquisition, de dépouillement et d’analyse, incompatibles avec les contraintes d’une ligne de production industrielle. Cet appel souhaite réduire d’abord ces différentes contraintes notamment en accélérant l’acquisition et l’analyse des données instrumentales. Il veut aussi pouvoir valoriser plus facilement les résultats de nano-caractérisations avancées.

Performance, Maintainability and Scalability of In-Silico Experimental Evolution Simulation (PMSISEE)


The goal of PMSISEE is to support the collaboration between the Avalon (LIP) and Beagle (LIRIS) teams through research activities on programming modelsand tools for HPC applied to the Aevol/R-Aevol simulator of in silico evolution of bacteria.

Scientific objective

A population of organisms adapting to a new environment is a dynamic system changing over time at many levels (molecules, networks, individuals, ecosystems). A large amount of empirical and theoretical evidence indicates that in real populations all these levels interact, making the dynamics of adaptation a highly complex phenomenon. In order to understand bacterial evolution, we need large-scale integrative models in which all relevant levels from the molecule to the ecology are simulated. The Aevol/R-Aevol simulator ( has been developed by the Beagle team to address such questions. Aevol integrates the molecular and cellular levels to address the evolution of genomic complexity. R-Aevol adds the network level to investigate the evolution of network complexity.


In this project we consider the Aevol/R-Aevol simulator, or equivalent code, as the object of the study. At a first glance, it is characterized by several properties: the code is complex due the models to integrate; the amount of computational resources required for simulations is huge when considering the size of the systems (millions of base pairs in the genome, thousands of genes in the genetic network, billions of individuals in the population, billions of generations); load unbalance occurs when running the models under different conditions ( i.e., different parameters). Any gain in performance, will make these simulations very valuable to understand bacterial evolution and to have feedback on the biological models in order to improve them.

The research during the PMSISEE project will be restricted to two main issues related to the software and its algorithms: 1/ analysis and design of specialized models to tackle software complexity in the context of HPC using next generation of parallel supercomputers. This point is based on advances in software engineering of these last twenty years in particular with respect to code composability and re-use using component model; 2/ performance analysis and design of new, or improvement of existing, algorithms for scalable and efficient simulation of evolving bacterial populations on modern parallel architecture. This axis will deal with heuristics for scheduling in order to well balance the work load and reducing communication.

vHGW (virtual Home Gateway) project

vHGW (virtual Home Gateway) or how to save energy by running thousands of HGs on one server.vHGW project

According to the current studies, the telecom infrastructure is the major contributor for the ever increasing energy demand in the ICT sector and has a major part on carbon footprint to the environment. And surprisingly, more than 80% of this share is consumed by the Home Gateways (HGs).

Hence, in this preliminary work, we have explored the possibility of relocating some of the functionalities of a HG into a vHGW (virtual Home Gateway) which is hosted by a node located in NSP premises. Based on our experiment, it was possible to host up to 1000 vHGWs on a single server machine which consumes around 100W. And our result showed that the number of vHGWs hosted on server machine does not have a significant variation on its energy consumption. We have also confirmed that the capability of a vHGW’s in the provision of the network and application level services such as, routing, DHCP, firewalling and NAT, alike HG’s.

If we consider a replacement of the current HG by a quasi passive device (which can consume around 1Watt) and if we suppose that end users have triple play services over a fiber link (FTTH). By pulling those network and application level services into a vHGW and using a server machine that can host around a 1000 vHGW’s (and probably more in a near future), we can obtain about 300% energy saving in the overall wire line telecom networks. Therefore, the result of our experiment is aligned to and complies with the recommendation set by the GreenTouch project (

Hence, the result of this study shows the benefit of service relocation of HG’s by reducing significantly the overall energy consumption of a wire line network, and minimizing the sector’s impact on the environment.

Inria Project Lab Discovery

Distributed and COoperative management of Virtual Environments autonomousLY

The DISCOVERY initiative aims at exploring a new way of operating Utility Computing (UC) resources.

To accommodate the ever-increasing demand for Utility Computing (UC) resources, while taking into account both energy and economical issues, the current trend consists in building larger and larger data centers in a few strategic locations. Although such an approach enables UC providers to cope with the actual demand while continuing to operate UC resources through centralized software system, it is far from delivering sustainable and efficient UC infrastructures. We claim that a disruptive change in UC infrastructures is required: UC resources should be managed differently, considering locality as a primary concern. To this aim, we propose to leverage any facilities available through the Internet in order to deliver widely distributed UC platforms that can better match the geographical dispersal of users as well as the unending demand. Critical to the emergence of such locality-based UC (LUC) platforms is the availability of appropriate operating mechanisms. We advocate the implementation of a unified system driving the use of resources at an unprecedented scale by turning a complex and diverse infrastructure into a collection of abstracted computing facilities that is both easy to operate and reliable.
