Running parallel meep on ubuntu: "Meep must be configured/compiled with MPB for add_eigenmode_source"

[berzoll]

Hello,

I am trying to install parallel meep on an Ubuntu AWS machine.
Following the installation instructions, I run the following commands:

"sudo apt-get install python3-meep-openmpi
sudo apt install python3-mpi4py"

I then install all the different packages needed with pip and run my script with "mpirun -np 1 python3 test.py" or "mpirun -np 1 python3 -u -m mpi4py test.py" (got only one core on this machine). The script runs fine until the line where I add the eigenmode source, which returns this output:

ubuntu@ip-172-31-13-101:~$ mpirun -np 1 python3 -u -m mpi4py test.py

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

What I am not doing correctly during the installation? I tried running "sudo apt-get install mpb-mpi" before installing meep, but to no use. Any hint how I could fix this?

Btw, seems that the AMI from Simpetus (http://www.simpetus.com/launchsims.html) does not exist anymore?

As mentioned in the docs, the preferred package manager solution is conda, which is the only one maintained by the meep developers.

Note that Meep (even the MPI version) uses the serial version of MPB. Note also that you probably need the mpb-dev package in order to get the header files etcetera.

Thank you both! I managed to set everything up with the conda packages just fine.
