Accès optimisés aux fichiers distants dans les grappes disposant d'un réseau rapide.

Abstract : Parallel applications running on computation clusters with high-speed interconnects require both effiient communications between processing nodes and fas taccess to the storage system.However, the software interface of these networks has been largely optimized for inter-nodes communication and thus does no fit the special requirements of distributed file systems.In this article we propose and study several solutions to make remote access to distant files performant on high-speed networks in clusters.Our ideas are implemented in the GM interface of MYRINETnetworks and then to their new interface,MX. You present the first performance comparisons between MX and GM and their efficiency in a distributed file system context.Our first results show that it is possible to efficiently interface distributed file systems with these networks
