Contribution au transfert de données : application à MPI

Abstract : MPI is a Standard that defines a library based upon the Message Passing concept, aimed at solving parallel problem by allowing direct communications between tasks. MPI has many basic data-types available, but the creation of data-types composed of other basic data-types is a long and repetitive process, eased by AUTOMAP. MPI has no mechanism for automatic transfer of pointer linked data-types : AUTOLINK is a library developed to answer the adaptation and transfer need of such a mecanism. Those tools compose the MPI DATA-TYPE TOOLS, and are the work discussed in this PhD thesis. We will present the evolution of the inner mechanisms as well as algorithms, describe the way AUTOLINK produces a serialized data to be transfered using buffers to enhance communications, present experimental studies of performances, explain uses of the MPI DATA-TYPE TOOLS, compare them with other similar tools, and finally possible extensions to the current algorithms will be introduced.
