The Open MPI Team has announced the release of Open MPI version 1.5. This release represents over a year of research, development, and testing. Open MPI uses a dual release cycle that includes a “super stable” (currently 1.4 series) and the recent “feature release” (1.5 series). One feature of note in the 1.5 series is the inclusion of KNEM a Linux kernel module enabling high-performance intra-node MPI communication for large messages (i.e. to improve large message performance within a single multi-core node). KNEM is also used in MPICH2 (since version 1.1.1).
A tip of the hat goes to Cluster Monkey for pointing us to this story.
