Dear Joaquin, In principle the process of compilation appears to be correct.
What is your execution command? You are using a -npool 8? The number of process (-np ) is equal to 64 in both cases, but in the second case I believe that you are using a -npool 8. For example, something like: /opt/openmpi/bin/mpirun -np 64 /opt/espresso-4.1.2/bin/pw.x -npool 8 < entrada.in Best regards, Andr?
