there are processes with no planes. Use pencil decomposition (-pd .true.)
How do I tell the code to use the pencil decomposition? I have tried
adding -pd to the 'mpirun' an adding use_pd=.true. in the PW inout but
in vain.
-pd .true. is a command-line option of the code, not of mpirun, so:
mpirun [options] pw.x -pd .true. [other options]
