  • Hablot, Ludovic; Glück, Olivier; Mignot, Jean-Christophe; Genaud, Stéphane; Vicat-Blanc Primet, Pascale (LIP, 2007-05)
    (eng) Today, clusters are often interconnected by long distance networks within grids to offer a huge number of available ressources to a range of users. MPI, the standard communication library used to write parallel ...
  • Guillier, Romaric; Hablot, Ludovic; Primet, Pascale; Soudan, Sébastien; Laboratoire de l'informatique du parallélisme (LIP, 2006-11)
    (eng) This report outline an evaluation of Ethernet links in Grid'5000, a French research grid built with 3000 processors on 9 sites. These sites are connected with dedicated 1 GbE or 10 GbE links. Efficient TCP parameters ...

    (eng) This paper examines the interactions between layer 2 (Ethernet) switches and TCP in high bandwidth delay product networks. First, the behavior of a range of Ethernet switches when two long lived connections compete ...
  • Guillier, Romaric; Hablot, Ludovic; Vicat-Blanc Primet, Pascale; Laboratoire de l'informatique du parallélisme (LIP, 2007-07)
    (ENG) Standard TCP faces some performance limitations in very high speed wide area networks, mainly due to a long end-to-end feedback loop and a conservative behaviour with respect to congestion. Many TCP variants have ...
