We have a few resources available every year to host interns, either with a sysadmin background or a systems developer background. We expect interns to mostly explore topics that are of interest to the technical team or to the user community, but that are not of high enough priority to be directly tackled by a technical team member. You'll find hereafter an example description, but please fell free to contact the technical director if you have other topics of interest and wish to know if it is of interest to us.

Interships available

We have a few resources available every year to host interns, either with a sysadmin background or a systems developer background. We expect interns to mostly explore topics that are of interest to the technical team or to the user community, but that are not of high enough priority to be directly tackled by a technical team member. You'll find hereafter an example description, but please fell free to contact the technical director if you have other topics of interest and wish to know if it is of interest to us.

Descriptions are in french.

Amélioration du Support des Paramètres CPU et BIOS dans Grid'5000

Contexte

Grid'5000 est une infrastructure de recherche pour l'étude de l'informatique distribuée (incluant les domaines HPC, Cloud, calcul parallèle, systèmes d'exploitation, systèmes pair-à-pair, réseau, etc.).

Cette plateforme est constituée de 1000 machines réparties sur 10 sites, interconnectés par un réseau rapide fournit par Renater et isolé d'Internet.

Ces ressources sont mises à disposition des équipes de recherche, qui ont la possibilité de reconfigurer l'ensemble de la pile logicielle des noeuds, ou de modifier le réseau, pour la durée d’une expérience.


Description du sujet

Grid'5000 laisse une grande liberté à ses utilisateurs pour la reconfiguration des ressources. Il est par exemple possible de réinstaller un Operating System complet sur les noeuds réservés.

Cependant, il n'est pas possible aujourd'hui de modifier certains paramètres liés au matériel, tels que ceux accessibles depuis le BIOS : l'Hyperthreading, les C-States ou le Turboboost, par exemple.

Hors, certains de ces paramètres ont une grande influence sur le comportement d'une machine, et par conséquent sur le résultat des expériences menées sur Grid'5000.

Le sujet de ce stage est d'améliorer le support de ces paramètres dans la plateforme.

Pour cela, plusieurs axes de travail sont envisagés :

  • Recensement des paramètres actuellement utilisés dans Grid'5000
  • Mise en place d'une configuration par défaut pour l'ensemble des ressources
  • Développement et mise à disposition d'outils pour modifier les paramètres
  • Documentation à destination des utilisateurs
  • Étude des technologies émergentes : UEFI, support dans les noyaux Linux récents, etc.
  • Intégration au gestionnaire de ressources OAR.

Le stagiaire travaillera au sein de l'équipe technique de Grid'5000.

Compétences requises

  • Architecture des systèmes et réseaux
  • Linux (administration, installation, maintenance, etc.)
  • Langages de script
  • Anglais technique et Français


Lieu

À définir parmi Nancy, Rennes, Lyon.

System and network administrator positions

Grid'5000 hires one to two systems and network administrators evry year. As an example, this is the annoucement made last year for a position in either Grenoble, Lille, Lyon, Nancy, or Rennes. More details. We expect next hiring period to open in May 2016 at the earliest.
