Dear Paolo,

Thank you so much for your prompt reply and running the test. I have followed 
your suggestion and submitted a calculation with only two CPU cores and the 
"-nk 2" option. Unfortunately, the result was exactly the same. It appears the 
issue is on our end.

We will request the installation of the latest QE version on our HPC and run 
tests with it. Hopefully that will fix the issue.

Thank you again for your assistance.

Best regards,
Gergely Nagy

It may or may not be related: if you have 2 GPUs, you should run 2 MPI
processes, preferably with k-point parallelization. Something like:
mpirun -np 2 pw.x -nk 2 ...
