he Open MPI Team, representing a consortium of research, academic, and industry partners, is pleased to announce the release of Open MPI version 1.8.2:
1.8.2 ----- - Fix auto-wireup of OOB, allowing ORTE to automatically test all available NICs - "Un-deprecate" pernode, npernode, and npersocket options by popular demand - Add missing Fortran bindings for MPI_WIN_LOCK_ALL, MPI_WIN_UNLOCK_ALL, and MPI_WIN_SYNC. - Fix cascading/over-quoting in some cases with the rsh/ssh-based launcher. Thanks to multiple users for raising the issue. - Properly add support for gfortran 4.9 ignore TKR pragma (it was erroneously only partially added in v1.7.5). Thanks to Marcus Daniels for raising the issue. - Update/improve help messages in the usnic BTL. - Resolve a race condition in MPI_Abort. - Fix obscure cases where static linking from wrapper compilers would fail. - Clarify the configure --help message about when OpenSHMEM is enabled/disabled by default. Thanks to Paul Hargrove for the suggestion. - Align pages properly where relevant. Thanks to Paul Hargrove for identifying the issue. - Various compiler warning and minor fixes for OpenBSD, FreeBSD, and Solaris/SPARC. Thanks to Paul Hargrove for the patches. - Properly pass function pointers from Fortran to C in the mpi_f08 module, thereby now supporting gfortran 4.9. Thanks to Tobias Burnus for assistance and testing with this issue. - Improve support for Cray CLE 5. - Fix mpirun regression: ensure exit status is non-zero if mpirun is terminated due to signal. - Improved CUDA efficiency of asynchronous copies. - Fix to parameter type in MPI_Type_indexed.3. Thanks to Bastian Beischer for reporting the mistake. - Fix NUMA distance calculations in the openib BTL. - Decrease time required to shut down mpirun at the end of a job. - More RMA fixes. - More hostfile fixes from Tetsuya Mishima. - Fix darray issue where UB was not computed correctly. - Fix mpi_f08 parameter name for MPI_GET_LIBRARY_VERSION. Thanks to Junchao Zhang for pointing out the issue. - Ensure mpirun aborts properly when unable to map processes in scheduled environments. - Ensure that MPI RMA error codes show up properly. Thanks to Lisandro Dalcin for reporting the issue. - Minor bug fixes and improvements to the bash and zsh mpirun autocompletion scripts. - Fix sequential mpirun process mapper. Thanks to Bill Chen for reporting the issue. - Correct SLURM stdout/stderr redirection. - Added missing portals 4 files. - Performance improvements for blocking sends and receives. - Lots of cleanup to the ml collective component - Added new Java methods to provide full MPI coverage - Many OSHMEM cleanups - Prevent comm_spawn from automatically launching a VM across all available nodes - Close many memory leaks to achieve valgrind-clean operation - Better handling of TCP connection discovery for mismatched networks where we don't have a direct 1:1 subnet match between nodes - Prevent segfault when OMPI info tools are used in pipes and user exits one step of that pipe before completing output
