Or set the MCA param "btl" to "^openib" (which means: not openib) -- either in

We are getting this message when OpenMPI starts up.

There should have been an error message right above that - all this is saying
is that the same error message was output by 7 more processes besides the one
that was output. It then indicates that process 3 (which has pid 0?) was killed.
Looking at the help message tag, it looks like no NICs were
Hello:
I am testing a rather large code on several computers. It works fine on all
except for a Linux Pop!_OS machine. I tried both OpenMPI 2.1.1 and 4.0.5. I
fear there is an issue because of the Pop!_OS but before I contact System76 I
would like to explore things further.
I get the follow

Thanks for your reponse, it works this time but when I tried again another job
without the command you gave me, I got the same warning!!,
should I use this command every time I want to run a job? there isn't another
method to tun off this warning for ever.
you forgot the "mpirun"
mpirun -mca btl_openib_warn_default_gid_prefix 0

I'm sorry for not communicating this accurately enough - you need to
add that line to your mpirun command. In other words, you need to
start your job with:
mpirun -mca btl_openib_warn_default_gid_prefix 0 .

Thank you for your response, but still my problem remains, I have used this
command:
-mca btl_openib_warn_default_gid_prefix 0
and I have got this message:
-bash: -mca: command not found
There are multiple ways to set MCA parameters - you can checkout the
FAQ to see all of them:
http://www.open-mpi.org/faq/?category=tuning#setting-mca-params
In your immediate case, just add -mca
btl_openib_warn_default_gid_prefix 0 to your cmd line.

Thank you for your response, and these are the details for my problem:
I have installed pwscf and then I have tried to run scf calculations, but
before having the output I got this warning message:
WARNING: There are more than one active ports on host 'stallo-2.local', but the
default subnet
I'm afraid that this isn't nearly enough information for us to help
you -- you haven't even specifically stated what your exact problem is.
Please submit all the information listed here:

Thanks.

Good morning,
after installing pwscf and running an example, I got a warning message
related to the MCA parameter. To fix it I have tried all the steps indicated in
