Hello Llolsten
Is there a specific reason you run as root? This practice is discouraged, isn't
it?
Also, isn't it true that OMPI uses ephemeral (i.e. 'user level, randomly
chosen') ports for TCP transport? In that case,
you can direct OpenMPI to only use a specific range of ports (that
should be open in your firewall configuration)
mpirun --mca oob_tcp_static_ipv4_ports - ...
if you use the tcp btl, you can (also) use
mpirun --mca btl_tcp_port_min_v4 --mca btl_tcp_port_range_v4
...
Cheers,
Gilles
