У меня Ubuntu Desktop LTS 16.04.1, и я сделал следующее. Я пошел в https://www.open-mpi.org/software/ompi/v2.0/, скачал OpenMPI-2.0.1.tar.gz и установил его с помощью следующих команд:Ubuntu mpi4py не компилируется
tar -xvf openmpi-2.0.1.tar.gz
cd openmpi-2.0.1
./configure --prefix="/home/$USER/.openmpi"
make
sudo make install
export PATH="$PATH:/home/$USER/.openmpi/bin"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/$USER/.openmpi/lib/"
echo export PATH="$PATH:/home/$USER/.openmpi/bin" >> /home/$USER/.bashrc
echo export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/$USER/.openmpi/lib/" >> /home/$USER/.bashrc
После того, как я установил mpi4py с помощью:
sudo apt-get update
sudo apt-get install python-mpi4py
После этого, Я создал файл Python (моя версия Python является Python 2.7.12) с именем something.py, имеющий следующие строки
from mpi4py import MPI
comm = MPI.COMM_WORLD
rank = comm.Get_rank()
print "hello world from process ", rank
Когда я пытаюсь запустить его с помощью Mpiexec -n 5 питона something.py, я получаю следующее:
-------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.

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):
opal_init failed
--> Returned value Error (-1) instead of ORTE_SUCCESS

Большинство решений говорят, установить OpenMPI непосредственно из источника, который я сделал, но это не похоже, чтобы решить мою проблему. У кого-то есть аналогичная проблема?
