The Open MPI Team, representing a consortium of research, academic, and
industry partners, is pleased to announce the release of Open MPI version
2.1.4. Open MPI v2.1.4 is a bug fix release, and is likely the last release in
the v2.1.x series.
Open MPI v2.1.4 is only recommended for those who are still running Open MPI
v2.0.x or v2.1.x, and can be downloaded from the Open MPI web site:
https://www.open-mpi.org/software/ompi/v2.1/
Item fixed in Open MPI 2.1.4 include the following:
- Disable the POWER 7/BE block in configure. Note that POWER 7/BE is
still not a supported platform, but it is no longer automatically
disabled. See
https://github.com/open-mpi/ompi/issues/4349#issuecomment-374970982
for more information.
- Fix bug with request-based one-sided MPI operations when using the
"rdma" component.
- Fix issue with large data structure in the TCP BTL causing problems
in some environments. Thanks to @lgarithm for reporting the issue.
- Minor Cygwin build fixes.
- Minor fixes for the openib BTL:
- Support for the QLogic RoCE HCA
- Support for the Boradcom Cumulus RoCE HCA
- Enable support for HDR link speeds
- Fix MPI_FINALIZED hang if invoked from an attribute destructor
during the MPI_COMM_SELF destruction in MPI_FINALIZE. Thanks to
@AndrewGaspar for reporting the issue.
- Java fixes:
- Modernize Java framework detection, especially on OS X/MacOS.
Thanks to Bryce Glover for reporting and submitting the fixes.
- Prefer "javac -h" to "javah" to support newer Java frameworks.
- Fortran fixes:
- Use conformant dummy parameter names for Fortran bindings. Thanks
to Themos Tsikas for reporting and submitting the fixes.
- Build the MPI_SIZEOF() interfaces in the "TKR"-style "mpi" module
whenever possible. Thanks to Themos Tsikas for reporting the
issue.
- Fix array of argv handling for the Fortran bindings of
MPI_COMM_SPAWN_MULTIPLE (and its associated man page).
- Make NAG Fortran compiler support more robust in configure.
- Disable the "pt2pt" one-sided MPI component when MPI_THREAD_MULTIPLE
is used. This component is simply not safe in MPI_THREAD_MULTIPLE
scenarios, and will not be fixed in the v2.1.x series.
- Make the "external" hwloc component fail gracefully if it is tries
to use an hwloc v2.x.y installation. hwloc v2.x.y will not be
supported in the Open MPI v2.1.x series.
- Fix "vader" shared memory support for messages larger than 2GB.
Thanks to Heiko Bauke for the bug report.
- Configure fixes for external PMI directory detection. Thanks to
Davide Vanzo for the report.
