Many-core architectures, such as the IBM Blue Gene/Q and Intel Xeon Phi, provide dozens of cores and hundreds of hardware threads. To utilize such architectures, application programmers are increasingly looking at hybrid programming models (frequently referred to as ``MPI+X’' models), where multiple threads interact with the MPI library. A common mode of operation for hybrid MPI+threads applications is where multiple threads are used to parallelize the computation, and one or more threads also issues MPI operations. While such a model is becoming increasingly popular because of the reducing per-core hardware resources available in modern architectures, it poses several challenges for the efficiency of MPI communication in such environments. In this talk, I’ll describe some of our recent work on optimizing MPI in such environments, either with multiple threads calling MPI operations or a single thread doing so
