I'll look at this tomorrow. Meanwhile, is it possible for you to use OpenMPI? In Debian-like distributions, you typically install the packages openmpi-bin and libopenmpi-dev.
(Also, did you really write --music-confing on the command line, or did this just happen when writing the issue text?)
Thanks! Openmpi used to give me issues with some other software I also need, but I can try again. As for your other question; there was indeed a typo in the command, but resolving the typo did not solve the problem (I get the very same error).
The MUSIC example works with OpenMPI! No issue with both the following commands:
$ mpirun -np 4 music python.music
$ mpirun -np 2 ./send.py --music-config python.music --app-label from : -np 2 ./receive.py --music-config python.music --app-label to
OpenMPI is fine with my personal situation, but the issue seems to remain if one needs to use the mpich implementation of MPI.
I am trying to execute the simple MUSIC demo example from the nest tutorial, but I get the following error:
I get a little more information by trying to run the example without using the music binary:
The README says this is likely due to an unexpected version of MPI, but I am not sure how to solve it. I am running mpich 3.3~a2-4, and nest-2.18.0 (installed with music and mpi) on Ubuntu 16.04. Thanks in advance.
