Parallel Neuron Help! - BAD TERMINATION
Posted: Fri Sep 11, 2015 1:52 pm
I recently upgraded to Neuron 7.4. I was able to configure Neuron with both python and mpi support. It may be of note that I had to use the flags --with-paranrn=dynamic and --with-nrnpython=dynamic to get make to run properly (viewtopic.php?f=4&t=3362). Neuron 7.4 now launches without issue.
However, when I try to run a program with the -mpi flag, I get an error. The error is shown below:

I haven't been able to find this error anywhere on the forums, or the internet for that matter. Can anyone help me?
