Abstract : The current trend of constructors for scientific computation is to build clusters whose node include an increasing number of cores.The classical programming model that is only based on MPI is being replaced by hybrid approaches that mix communication and multi-threading. This evolution of the programming model leads to numerous problems since MPI implementations were not designed for multi-threaded applications. In this thesis, in order to guarantee a smooth behavior of communication, we propose a software module that interact with both the threads scheduler and the communication library. This module, by working closely with the thread scheduler, allows to make communication progress in the background and guarantees a high level of reactivity to network events, even when the node is overloaded.
