Because today the clusters with multicore nodes are quite common and the
cores within a node share memory.

Which Implementations of MPI (no matter commercial or free), make automatic
and efficient use of shared memory for message passing within a node. (means
which MPI librarries auomatically communicate over shared memory instead of
interconnect on the same node).
