In that > light, v2.0.0rc3 is now available: > > https://www.open-mpi.org/software/ompi/v2.x/ > <https://www.open-mpi.org/software/ompi/v2.x/> > Here are the changes since 2.0.0rc2: > > - The MPI C++ bindings -- which were removed from the MPI standard in > v3.0 -- are no longer built by default and will be removed in some > future version of Open MPI. Use the --enable-mpi-cxx-bindings > configure option to build the deprecated/removed MPI C++ bindings. > > --> NOTE: this is not new, actually -- but we just added it to the NEWS file. > > - In environments where mpirun cannot automatically determine the > number of slots available (e.g., when using a hostfile that does not > specify "slots", or when using --host without specifying a ":N" > suffix to hostnames), mpirun now requires the use of "-np N" to > specify how many MPI processes to launch. > > - Many updates and fixes to the revamped memory hooks infrastructure > > - Various configure-related compatibility updates for newer versions > of libibverbs and OFED. > > - Properly detect Intel TrueScale and OmniPath devices in the ACTIVE > state. Thanks to Durga Choudhury for reporting the issue. > > - Fix MPI_IREDUCE_SCATTER_BLOCK for a one-process communicator. Thanks > to Lisandro Dalcin for reporting. > > - Fix detection and use of Solaris Studio 12.5 (beta) compilers. > Thanks to Paul Hargrove for reporting and debugging. > > - Allow NULL arrays when creating empty MPI datatypes. > > - Miscellaneous minor bug fixes in the hcoll component. > > - Miscellaneous minor bug fixes in the ugni component. > > - Fix various small memory leaks. > > - Notable new MCA parameters: > > - opal_progress_lp_call_ration: Control how often low-priority > callbacks are made during Open MPI's main progress loop. > > - Disable backtrace support by default in the PSM/PSM2 libraries to > prevent unintentional conflicting behavior. > > Thanks, > > Howard > > -- > > Howard Pritchard > HPC-DES > Los Alamos National Laboratory > > >
