Journée CERNA "les valeurs dans les algorithmes et les données" le vendredi 4 mai 2018 à Paris

Vendredi 4 mai journée CERNA "les valeurs dans les algorithmes et les données"
à Inria Paris, 12e

Les algorithmes et les données reflètent les valeurs de la société. Cela peut être l'effet d'un choix délibéré, par exemple lorsque l'architecture du système est conçue afin de respecter les droits de ses utilisateurs. Mais cela peut aussi résulter de la subjectivité du programmeur. Celui-ci peut décider que le système demeure, ou pas, loyal vis-à-vis de l'utilisateur, comme dans la décision de favoriser la sécurité des passagers d'un véhicule autonome. Il peut, implicitement ou explicitement, rendre le comportement du système manipulateur (nudging) ou tout simplement contraire à l'éthique (les injures proférées par les chatbots). Le déploiement des systèmes numériques à grande échelle amène ainsi la société à poser un nouveau regard sur les valeurs. Différents aspects de ces problèmes seront abordés dans leurs principes, et illustrés dans le contexte industriel et universitaire.

Formation Hyperledger Fabric et Hyperledger Cello le 19 février 2018 de 9h à 12h

La formation Hyperledger, qui avait été annulée en janvier, a été reprogrammée pour le 19 Février de 9h à 12h. Les intervenants du CATIE viendront en particulier présenter Hyperledger Fabric et Hyperledger Cello.

Afin d'éviter les problèmes techniques le jour de la formation, merci de préparer votre environnement à l'avance. Les informations d'installation peuvent être trouvées au lien suivant : http://blockchain.lacaud.fr/ . Des machines virtuelles déjà toutes prêtes et utilisables avec VirtualBox peuvent également être téléchargées au même lien.

Exposé invité de Alain Tchana (INP Toulouse) le 02/02/2018 à 10h30 dans l'amphi du Labri

Bonjour à tous,

Alain Tchana de l'INPT fera un exposé le vendredi 02/02/2018 à 10h30 dans l'amphi du Labri sur:

Energy saving and performance improvement in virtualized datacenters

Summary:
Numerous companies rely on cloud infrastructures for hosting their services because of their
attractive costs. Electricity consumption is a major challenge in such infrastructures, it
represents around 50% to 70% of the expenditures. It doubles every five years due to
explosive growth in both the number and density of datacenters, according to the last Berkeley Lab report. So, this is also a critical issue for the planet because electricity consumption results in CO2 emission. Existing approaches, based on virtual machine (VM) packing and dynamic server power scaling, have reached their limit because of the server-centric architecture of datacenters on the one hand and the server bounded limitation of VM monitors on the other hand. The new trend to go further consists in building future datacenters as giant computers, called disaggregated datacenters. I will present my major contributions in this direction.

Bio:
Since September 2013, Alain Tchana is Associate Professor - HDR at ENSEEIHT-INPT. His Ph.D. thesis was on research topics related to autonomic administration systems. The latter are middleware services which allow administration tasks to be automated (self-deployment, self-repair, self-*). In particular, he worked on the autonomic administration of cloud infrastructures. Since he was recruited as Associate Professor, he moved to the virtualization and operating system domains, (the good layers for addressing issues in their generality). The next step in his research path is the exploration of the future computer architectures for cloud infrastructures.

Séminaire de Hermann Hellwagner sur le "Dynamic Adaptive Streaming over Named Data Networking" le 21/11/2017 de 10h à 11h en salle 076 du Labri

Dynamic Adaptive Streaming over Named Data Networking

Hermann Hellwagner (joint work with Daniel Posch and Benjamin Rainer)
Multimedia Communication Research Group
Institute of Information Technology
Alpen-Adria-Universität Klagenfurt (AAU), Austria

Modern digital video portals and streaming services typically store multiple, differently encoded variants of the available videos and employ adaptation techniques in order to adapt the volume and quality of the transmitted video data, in response to, e.g., dynamically varying network throughput conditions or specific constraints of end devices. In the past decade, client-driven adaptive video delivery techniques have become prevailing in practice, e.g., the standardized Dynamic Adaptive Streaming over HTTP(DASH) scheme or its proprietary variants. The Multimedia Communication research group at AAU has for several years explored DASH-type schemes. The spin-off company BITMOVIN successfully productized the software and extended it substantially. 

In this talk, though, we will present a second line of research that developed out of the first one, namely how to realize Dynamic Adaptive Streaming(DAS) over Named Data Networking (NDN), a specific and promising architecture variant of Information-Centric Networking (ICN) investigated as part of Future Internet initiatives. The basic NDN architecture was designed several years ago by Jacobson et al. at PARC to address – in the network layer – many functions of nowadays’ application layer and Content Distribution Networks (CDNs), like awareness of content chunks being transferred, caching, and content processing/adaptation. 

We will introduce the NDN concepts and the basic DAS over NDN mechanisms, derive upper performance bounds, and specifically discuss how a novel adaptive forwarding scheme can greatly improve performance and service quality for dynamic adaptive video streaming over NDN. Results have been gained via NDN simulations and the research group’s NDN testbed.
