Open MPI v5.0.0rc6 is now available for testing at https://www.open-mpi.org/software/ompi/v5.0/<https://www.open-mpi.org/software/ompi/v5.0/>.
Please test and send feedback either via the user mailing lists or create an issue at https://github.com/open-mpi/ompi/issues/<https://github.com/open-mpi/ompi/issues/>. Changelog from rc5 includes: * The PRRTE submodule pointer has been updated to bring in the following fixes: * Fixed a bug where the deprecated option "--oversubscribe" for mpirun was not translated correctly to its new equivalent ("--map-by :oversubscribe"). * Fixed a case where "--map-by ppr:x:oversubscribe" would not work correctly. In this case, ":oversubscribe" was effectively ignored. * Fixed incorrect behavior with "MPI_Allreduce()" when using "MPI_MAX" with the "MPI_UNSIGNED_LONG" type. Thanks to Kendra Long for the report and their contribution to the fix. * Various fixes to the "openmpi.spec" file to fix issues with rpm generation. * Fixed a bug in one-sided UCX calls where not all in-flight messages would be flushed before cleanup. * Build fixes - the following builds options with Open MPI were fixed: * usNIC - ("configure --with-usnic=..") * HCOLL - ("configure --with-hcoll=..") * XPMEM - ("configure --with-xpmem=.."). * Thanks to Alex Margol for the fix. * Various documentation improvements and updates.
