Open MPI v2.1.4rc1 has been pushed. It is likely going to be the last in the v2.1.x series (since v4.0.0 is now visible on the horizon). It is just a bunch of bug fixes that have accumulated since v2.1.3; nothing huge. We'll encourage users who are still using the v2.1.x series to upgrade to this release; it should be a non-event for anyone who has already upgraded to the v3.0.x or v3.1.x series.
https://www.open-mpi.org/software/ompi/v2.1/ If no serious-enough issues are found, we plan to release 2.1.4 this Friday, August 10, 2018. Please test! Bug fixes/minor improvements: - 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. -- Jeff Squyres jsquy...@cisco.com _______________________________________________ devel mailing list email@example.com https://lists.open-mpi.org/mailman/listinfo/devel
