Dear all,I have tested the image-example for phonon calculations using QuantumEspresso 6.3. In the case I am using these commands:
mpirun -np 4 pw.x < ... mpirun -np 4 ph.x -ni 2 < ... mpirun -np 4 ph.x < .... everything works fine. However, using this: mpirun -np 2 pw.x < ... mpirun -np 4 ph.x -ni 2 < ... mpirun -np 2 ph.x < ....yields an error in the last step: "pw.x run with a different number of processors. Use wf_collect=.true." However, I have the same number of processors in pw.x and ph.x and the wf_collect option is activated by default. So I don't know what is going on.
