Package: python-mpi4py
Version: 1.2.2-3
Severity: normal
Dear Maintainer,
On a fresh Ubuntu 12.04 amd64 install, with
$ sudo apt-get install python-mpi4py --no-install-recommends
mpi4py is not usable:
$ python -ic "import mpi4py.MPI"
[salinas:24750] [[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
--------------------------------------------------------------------------

*** The MPI_Init_thread() function was called before MPI_INIT was invoked.
*** This is disallowed by the MPI standard.
*** Your MPI job will now abort.
[salinas:24750] Abort before MPI_INIT completed successfully; not able to
guarantee that all other processes were killed!
Installing the recommended mpi-default-bin fixes it:
$ sudo apt-get install mpi-default-bin --no-install-recommends
....
$ python -ic "import mpi4py.MPI"
>>> mpi4py.MPI.COMM_WORLD.size
1
***
I realize the issue is a bit contrived -- what use is mpi4py without mpirun?
-- but the error was quite surprising and didn't give a lot of indication as to
the cause.
I do not know if this impacts other architectures, especially those where mpi-
default != openmpi.

Closes: 670768 675520
Changes:
mpi4py (1.3-1) unstable; urgency=low
.
[ Bradley M. Froehle ]
* New upstream release (Closes: #675520)
* Import "Safer Cython version check" from upstream to allow building
against pre-release versions of Cython
* Fix FTBFS issues on some platforms where the default MPI implementation
is not OpenMPI
* python-mpi executables are not packaged; they are not required by OpenMPI
or MPICH2
.
[ Yaroslav Halchenko ]
* Boosted mpi-default-bin into Depends from Recommends since according
to tireless Bradley otherwise it is useless (Closes: #670768)
