The Open MPI Team, representing a consortium of research, academic, and industry partners, is pleased to announce the release of Open MPI version 1.8.1.
*** This release includes a single critical bug fix for users who run MPI jobs
as the "root" user. It is otherwise identical to the Open MPI v1.8 release.
See https://svn.open-mpi.org/trac/ompi/ticket/4536 for more details.
Version 1.8.1 can be downloaded from:
Note that v1.8.2 is expected to be released within the next few weeks, and will contain the usual bug fixes and end user-suggested improvements. The Open MPI team felt that this critical bug warranted an immediate release, but did not want to interrupt the normal post-v1.8 bug fix/improvement schedule already in progress. Hence, we are releasing v1.8.1 with this one critical bug fix, and keeping on track with all other fixes for the next release in a few weeks.
If you do not run Open MPI jobs as root, you do not need the v1.8.1 release; you can wait for v1.8.2.
As usual, MPI application ABI will be preserved through the v1.8.x series.
