I am trying to run QE 6.8 on a supercomputer node with 128 cores ... I use pure MPI parallelization Run on 16 and 32 cores works OK ...
Run on 64+ cores ends with following error: Error in routine fft_type_set (6): there are processes with no planes. Use pencil decomposition (-pd .true.) Can anybody explain what it means ? Is my system to simple to it can not feed all cores ? Where can I enter the -pd .true. option ?
