Package: libboost-mpi-python1.49.0 Version: 1.49.0-3.1 Severity: grave If I try to import boost.mpi from a Python script that is not run through mpirun and openmbi-bin is not installed, the import fails with:
[earth:26793] [[INVALID],INVALID] ORTE_ERROR_LOG: A system-required executable
either could not be found or was not executable by this user in file
../../../../../../orte/mca/ess/singleton/ess_singleton_module.c at line 357

--------------------------------------------------------------------------
It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
orte_ess_set_name failed
--> Returned value A system-required executable either could not be found or
was not executable by this user (-127) instead of ORTE_SUCCESS

It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_INIT; some of which are due to configuration or environment
problems. This failure appears to be an internal failure; here's some
additional information (which may only be relevant to an Open MPI
developer):
ompi_mpi_init: orte_init failed
--> Returned "A system-required executable either could not be found or was
not executable by this user" (-127) instead of "Success" (0)
--------------------------------------------------------------------------
*** The MPI_Init() function was called before MPI_INIT was invoked.
*** This is disallowed by the MPI standard.
*** Your MPI job will now abort.
[earth:26793] Abort before MPI_INIT completed successfully; not able to
guarantee that all other processes were killed!
and causes the Python interpreter to exit immediately. I don't think that's an
acceptable behavior. It should handle this situation more gracefully and
throw an exception instead or depend an openmpi-bin if that's the
appropriate thing.
Furthermore boost.mpi breaks Python's pydoc:
>>> import pydoc; pydoc.help("modules")
fails with the same error message and exits the Python instance. Also the
command suggested in Boost's documentation to get help on boost.mpi
(pydoc boost.mpi) doesn't work.
