    • Platform upgraded to 1.7.0.
  • Feb 3rd, 2006 : A major security hole found in Linux
    This does not directly concern XtremWeb, but may occur on Linux machines, including Linux workers:

    It seems that Linux kernel, up to 2.4.23, does not include OOM (Out Of Memory) process. This may leads to serious damages, including data loss, if any process (submitted with XtremWeb or not) requests far more than available memory.
    Linux 2.6.x does not seem to suffer such lacks.

    This is still under expertise…

Introduction à DGHEP

Le projet Desktop Grid for High Energy Physics (DGHEP) propose d’étudier différentes plates-formes de calcul global afin de comprendre les intérêts que les chercheurs pourraient en tirer pour satisfaire leurs besoins toujours plus grands en termes de ressources de calcul.

Dans le cadre de ce projet, nous étudions :

  • XtremWeb, la plate-forme de l’INRIA;
  • Xgrid, la plate-forme d’Apple;
  • Boinc, la plate-forme de Berkeley.

De part l’engagement du LAL auprès de l’INRIA, nos travaux commencent "naturellement" par XtremWeb.

Pour les tests préliminaires, cette plate-forme a été déployée pour prendre en charge les calculs de l’expérience Auger.
Les résultats sont automatiquement sauvegardés sur le robot de stockage du CC IN2P3, à Lyon.
