  • Accès optimisés aux fichiers distants dans les grappes disposant d'un réseau rapide.
    Laboratoire de l'informatique du parallélisme; Goglin, Brice; Glück, Olivier; Vicat-Blanc Primet, Pascale (2004-12)
    (eng) L'exécution performante d'applications parallèles sur grappes de calcul interconnectées par des réseaux hautes performances nécessite des communications efficaces entre les processus de calcul mais aussi des accès ...
  • Comparison and tuning of MPI implementations in a grid context
    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 ...
  • An Efficient Network API for in-Kernel Applications in Clusters
    Laboratoire de l'informatique du parallélisme; Goglin, Brice; Glück, Olivier; Vicat-Blanc Primet, Pascale (2005-04)
    (eng) Running parallel applications on clusters with high-speed local networks requires fast communication between computing nodes but also low latency and high bandwidth file access. However, the application programming ...
  • Interaction efficace entre les réseaux rapides de stockage distribué dans les grappes de calcul
    Goglin, Brice; Glück, Olivier; Vicat-Blanc Primet, Pascale; Laboratoire de l'informatique du parallélisme (LIP, 2006-01)
    (eng) Parallel applications running on clusters require both highperformance communications between nodes and efficient access to the storage system. We propose to improve the performance of distributed storage systems ...
  • Optimizing Network Resource Sharing in Grids
    Laboratoire de l'informatique du parallélisme; Marchal, Loris; Robert, Yves; Vicat-Blanc Primet, Pascale; Zeng, Jingdi (2005-03)
    (eng) While grid computing reaches further to geographically separated clusters, data warehouses, and disks, it poses demanding requirements on end-to-end performance guarantee. Its pre-defined destinations and service ...
  • Scheduling network requests with transmission window
    Marchal, Loris; Robert, Yves; Vicat-Blanc Primet, Pascale; Zeng, Jingdi; Laboratoire de l'informatique du parallélisme (2005-07)
    (eng) We consider the problem of bulk data transfers and bandwidth sharing in the context of grid infrastructures. Grid computing empowers high-performance computing in a large-scale distributed environment. Network ...
  • Study of a non intrusive and accurate method for measuring the end-to-end useful bandwidth
    Laboratoire de l'informatique du parallélisme; Goutelle, Mathieu; Vicat-Blanc Primet, Pascale (2003-10)
    (eng) Studies and tools development for applications sensitive to data rates is a very active research field for distributed application performance optimization. The research community works to propose tools for measuring ...
  • TCP variants and transfer time predictability in very high speed networks
    Guillier, Romaric; Soudan, Sébastien; Vicat-Blanc Primet, Pascale; Laboratoire de l'informatique du parallélisme (LIP, 2007-07)
    (ENG) In high performance distributed computing applications, data movements have demanding performance requirements such as reliable and predictable delivery. Predicting the throughput of large transfers is very difficult ...
  • Towards a user-oriented benchmark for transport protocols comparison in very high speed networks
    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 ...
