Shared memory topology
Webb4 juli 2012 · With most distributed memory platforms nowadays consisting of SMP or NUMA nodes it just makes no sense to not use OpenMP. OpenMP and MPI can perfectly work together; OpenMP feeds the cores on each node and MPI communicates between the nodes. This is called hybrid programming. Webb1 What is Shared Memory?

Shared Memory with “Non Uniform Memory Access” time (NUMA) There is logically one address space and the communication happens through the shared address space, as in the case of a symmetric shared memory architecture. One processor writes the data in a shared location and the other processor reads it from the shared location. 2.
WebbWe compare our shared-memory allreduce with several traditional MPI implementations -- Open MPI, MPICH2, and MVAPICH2 -- that utilize system shared memory to facilitate interprocess communication.
WebbIn the shared memory model of parallel computing, processes running on separate processors have access to a shared physical memory and therefore they have access to shared data. This shared access is both a blessing and a curse to the programmer.
