Hi Gilles,
Thanks for the suggestions; the results are below. Any ideas where to go
from here?
- Seems that selinux is not installed:
user@b09-30:~$ sestatus
The program 'sestatus' is currently not installed. You can install it by

Konstantinos,
You need to double check that, your OS might have done it out of the box
for you already.
Once logged, you can
which mpirun
If it resolves to /usr/local/bin/mpirun, then there is no need to update

undoubtablely better than ethernet, which is pro
