Thanks to Stack Overflow user @Seriously for reporting the issue. - PMIx updates: - Fix compatibility with external PMIx v4.x installations. - Fix handling of PMIx v3.x compiler/linker flags. Thanks to Erik Schnetter for reporting the issue. - Skip SLURM-provided PMIx detection when appropriate. Thanks to Alexander Grund for reporting the issue. - Fix handling by C++ compilers when they #include the STL "<version>" header file, which ends up including Open MPI's text VERSION file (which is not C code). Thanks to @srpgilles for reporting the issue. - Fix MPI_Op support for MPI_LONG. - Make the MPI C++ bindings library (libmpi_cxx) explicitly depend on the OPAL internal library (libopen-pal). Thanks to Ye Luo for reporting the issue. - Fix configure handling of "--with-libevent=/usr". - Fix memory leak when opening Lustre files. Thanks to Bert Wesarg for submitting the fix. - Fix MPI_SENDRECV_REPLACE to correctly process datatype errors. Thanks to Lisandro Dalcin for reporting the issue. - Fix MPI_SENDRECV_REPLACE to correctly handle large data. Thanks Jakub Benda for reporting this issue and suggesting a fix. - Add workaround for TCP "dropped connection" errors to drastically reduce the possibility of this happening. - OMPIO updates: - Fix handling when AMODE is not set. Thanks to Rainer Keller for reporting the issue and supplying the fix. - Fix FBTL "posix" component linking issue. Thanks for Honggang Li for reporting the issue. - Fixed segv with MPI_FILE_GET_BYTE_OFFSET on 0-sized file view. - Thanks to GitHub user @shanedsnyder for submitting the issue. - OFI updates: - Multi-plane / Multi-Nic nic selection cleanups - Add support for exporting Open MPI memory monitors into Libfabric. - Ensure that Cisco usNIC devices are never selected by the OFI MTL. - Fix buffer overflow in OFI networking setup. Thanks to Alexander Grund for reporting the issue and supplying the fix. - Fix SSEND on tag matching networks. - Fix error handling in several MPI collectives. - Fix the ordering of MPI_COMM_SPLIT_TYPE. Thanks to Wolfgang Bangerth for raising the issue. - No longer install the orted-mpir library (it's an internal / Libtool convenience library). Thanks to Andrew Hesford for the fix. - PSM2 updates: - Allow advanced users to disable PSM2 version checking. - Fix to allow non-default installation locations of psm2.h. _______________________________________________ announce mailing list announce@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/announce
