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 [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 230 [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/runtime/orte_init.c at line 132 -------------------------------------------------------------------------- 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_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. -- System Information: Debian Release: wheezy/sid APT prefers precise-updates APT policy: (500, 'precise-updates'), (500, 'precise-security'), (500, 'precise'), (100, 'precise-backports') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-24-generic (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages python-mpi4py depends on: ii libc6 2.15-0ubuntu10 ii libopenmpi1.3 1.4.3-2.1ubuntu3 ii python 2.7.3-0ubuntu2 ii python-support 1.0.14ubuntu2 Versions of packages python-mpi4py recommends: ii mpi-default-bin 1.0.1 Versions of packages python-mpi4py suggests: ii python-numpy 1:1.6.1-6ubuntu1 -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
