Research / Recherche

My research activities focus on experimentation for the evaluation of distributed systems in the context of High Performance Computing, Cloud and Grid Computing and Peer-to-peer systems. Specifically, I focus on emulation (through work on the Distem emulator), and on real-scale (in situ) experiments, mainly on the Grid'5000 testbed.

Projects :

• ADT INRIA Aladdin-Grid'5000: Member of the executive and technical committees, chief scientist in Nancy
• AEN INRIA Hemera: leader of a working group on Completing challenging experiments on Grid'5000
• SimgLite (projet interfaces Recherche sur les grilles / Grilles de production -- Grid'5000 / Institut des Grilles)
• Co-coordinator of the CPER MISN project Expérimentations et calculs distribués à grande échelle (EDGE)
• INRIA ADT Kadeploy
• INRIA ADT Solfege
• Distem - DISTributed system EMulator

  Résumé :
  Cette thèse s'inscrit dans le domaine de l'expérimentation sur les systèmes distribués, et en particulier de leur test ou de leur validation. À côté des méthodes d'évaluation classiques (modélisation, simulation, plates-formes d'expérimentation comme PlanetLab ou Grid'5000) les méthodes basées sur l'émulation et la virtualisation proposent une alternative prometteuse. Elles permettent d'exécuter l'application réelle à étudier, en lui présentant un environnement synthétique, correspondant aux conditions d'expérience souhaitées : il est ainsi possible, à moindre coût, de réaliser des expériences dans des conditions expérimentales différentes, éventuellement impossibles à reproduire dans un environnement réel. Mais l'utilisation de tels outils d'émulation ne peut se faire sans répondre à des questions sur leur réalisme et leur passage à l'échelle.

  Dans ce travail, nous utilisons une démarche incrémentale pour construire une plate-forme d'émulation destinée à l'étude des systèmes pair-à-pair à grande échelle. Nous commençons par comparer les différentes solutions d'émulation logicielle de liens réseaux, puis illustrons leur utilisation, notamment en étudiant une application réseau complexe : TUNS, un tunnel IP sur DNS. Nous construisons ensuite notre plate-forme d'émulation, P2PLab, en utilisant l'un des émulateurs réseaux précédemment étudiés, ainsi qu'un modèle de topologies réseaux adapté à l'étude des systèmes pair-à-pair. Nous y proposons une solution légère de virtualisation, permettant un bon rapport de repliement (grand nombre de noeuds émulés sur chaque machine physique). Après avoir validé cette plate-forme, nous l'utilisons pour étudier le protocole de diffusion de fichiers pair-à-pair BitTorrent à l'aide d'expériences mettant en jeu près de 15000 noeuds participants.

Non-academic talks

In another life, I am a Free Software developer, involved mainly in Debian, where I focus on Quality Assurance (working on infrastructure like Ultimate Debian Database and on archive-wide testing, like ensuring that all packages in Debian can be rebuilt from source or can still be installed. I am also known for my work on improving collaboration between Debian and Ubuntu (see this LWN article, for example). And I enjoyed writing some applications in Ruby to scratch some itches, like feed2imap.

Below are some slides from talks I gave at Free Software conferences.

Teaching / Enseignement

Je suis Maître de conférences à l'Université de Lorraine, affecté à l'IUT Nancy-Charlemagne. Je réalise une partie importante de mon service en Licence Professionnelle Administration de systèmes, réseaux et applications à base de logiciels libres (ASRALL).

Code

• Katapult: tool for automating the deployment of nodes using Kadeploy. homepage.
• NISTNet on recent Linux kernels (2.6.26+). More.

  The original NISTNet doesn't work on recent Linux kernels. There are some instructions (and a patch) to make it work on more recent kernels available here, but even this patch fails to work with more recent Linux kernels (apparently it worked until Linux 2.6.24). Here is an updated patch that is known to work with Linux 2.6.26. It applies to nistnet.2.0.12c.tar.gz, and the normal installation instructions work fine, provided that you install the necessary build dependencies (for Debian, at least x-dev libxt-dev libxmu-headers libxaw7-dev libc6-dev-i386 xmkmf xaw3dg-dev).

  Another problem is that recent distribution kernels enable HPET, which breaks NISTNet. You need to recompile your kernel to disable it. Here is a patch against Debian's 2.6.26 kernel configuration that is known to work (a simpler diff might work too).

  Note: if you are a Grid'5000 user, a sid-x64-base-1.1-nistnet image is available on Orsay (user lnussbaum). Log in as root, cd nistnet-3.0a, run make install, modprobe nistnet, and use cnistnet.

• iperf's reverse mode. More.

  iperf is a popular tool to measure network throughput. However, it can only be used to measure throughput from the iperf client to the iperf server. This is a problem when one wants to measure the throughput in both directions, and one of the hosts is behind a NAT/firewall. This patch adds a reverse mode, where the data is transfered from the server to the client, allowing to measure the download throughput. This mode is enabled by specifying the -2 option. The patch has been submitted to iperf's authors, but hasn't been included yet.

  iperf's reverse mode patch, applies against iperf 2.0.4.

• Linux kernel patch to enable/disable SCTP checksum computation via sysctl. More.

  With SCTP, computing CRC32 checksums is known to add a signifiant overhead. Unfortunately, most NICs don't support offloading that computation. To be able to achieve Gigabit-grade bandwidth with SCTP with current hardware, it is required to disable SCTP checksumming. This is only possible by manually modifying the SCTP implementation. This patch adds a module option (no_checksums) that allows to easily disable checksums computation.

  Note: This breaks protocol compliance. You won't be able to communicate with hosts where checksums are enabled.
