Thanks to Andreas Kempf for reporting the issue. - Fix OpenSHMEM crash when running on non-Mellanox MXM-based networks. Thanks to Debendra Das for reporting the issue. - Fix a crash occuring after repeated calls to MPI_FILE_SET_VIEW with predefined datatypes. Thanks to Eric Chamberland and Matthew Knepley for reporting and helping chase down this issue. - Fix stdin propagation to MPI processes. Thanks to Jingchao Zhang for reporting the issue. - Fix various runtime and portability issues by updating the PMIx internal component to v1.1.5. - Fix process startup failures on Intel MIC platforms due to very large entries in /proc/mounts. - Fix a problem with use of relative path for specifing executables to mpirun/oshrun. Thanks to David Schneider for reporting. - Various improvements when running over portals-based networks. - Fix thread-based race conditions with GNI-based networks. - Fix a problem with MPI_FILE_CLOSE and MPI_FILE_SET_SIZE. Thanks to Cihan Altinay for reporting. - Remove all use of rand(3) from within Open MPI so as not to perturb applications use of it.
