  • rebuilt OpenMPI w/o multi-threading support.

Bugs fixed

  • OpenMPI: Users trying the parallel hdf5 writer mpio driver through h5py, or certain advanced features of mpi4py experienced thread based deadlock due to a bug in openmpi's implementation of multi-threaded support. This has been resolved by disabling openmpi multi-threaded support. Consequently, users, or libraries that call MPI_Init_Thread will now get output that indicates multi-threaded support from the MPI implementation is not available. (some details are found in JIRA issue PSRT-21).
