Dear all,
running this script:
import mpi4py
from mpi4py import MPI
import h5py
rank = MPI.COMM_WORLD.rank # The process ID (integer 0-3 for 4-process run)
print(rank)
f = h5py.File('parallel_test.hdf5', 'w', driver='mpio', comm=MPI.COMM_WORLD)
dset = f.create_dataset('test', (4,), dtype='i')
dset[rank] = rank
f.close()
yields this result, for both python versions for as well 14.04 as 16.04
(Kubuntu):
$ mpirun -np 4 python3 multiproc_hdf5_mpi4py.py

-------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status,
thus causing
the job to be terminated. The first process to do so was:
Process name: [[43945,1],1]
Exit code: 1
I have googled it, and it seems that the package must be rebuilt, with
the correct options referring it to the installation of mpi. I tried
rebuilding the package myself, but was not (yet) able to figure out
where to actually change that settings. (debian/rules? how?).
Perhaps you could fix this in the central repository as package maintainers?
Kind regards,
Lars B
