Enter your e-mail address to be notified when new releases of Open MPI are released

Your email address will be used only to send you announcements about new releases of Open MPI and you will be able to un-subscribe at any time.

Changes in this release:

  • See this page if you are upgrading from a prior major release series of Open MPI. It shows the Big Changes for which end users need to be aware.
  • See the NEWS file for a more fine-grained listing of changes between each release and sub-release of the Open MPI v4.1 series.

See the version timeline for information on the chronology of Open MPI releases.

NOTE: Open MPI 4.1.7 incorrectly changed the shared library versioning information for the OpenSHMEM interface, potentially causing link errors when updating from prior releases of Open MPI to 4.1.7. Open MPI 4.1.8 resets the shared library version number history to allow updates from Open MPI 4.1.6 and prior. Customers who updated to 4.1.7 and relinked their OpenSHMEM applications will have to relink their application again when updating to Open MPI 4.1.8 or later.
