mpiexec fails on linux

Post by MBeining » Sun Nov 05, 2017 8:05 am

This is a kind of follow-up post of this thread about mpiexec problems in Windows:
viewtopic.php?f=31&t=3769&p=16167#p16167

Trying to run the test0.hoc on Ubuntu gave me this error:

Code: Select all

mpiexec -n 2 nrniv -mpi /usr/local/nrn/test0.hoc
Try loading openmpi
load_mpi: libmpi.so successful
load_nrnmpi: /usr/local/nrn/x86_64/lib/libnrnmpi.so: undefined symbol: ompi_mpi_int
I installed the mpich package via apt. The Neuron version is: 7.5 master (6b4c19f) 2017-09-25.
Any idea what the problem might be?
Thank you in advance

Ok, I found out that using Open MPI, the test0.hoc works.
Guess Neuron is not compatible with mpich, only with mpich2? (which was not available to install via apt on that machine)
