[Pw_forum] Error in pw.x with QE 5.4 version

Dear Pradip, the kind of error you got might be a problem of your
executable, or might be related to very specific cases of parallel
execution. It is impossible to do anything without (and sometimes even
with) an exact description of what happens under which conditions. I
made a quick test and it works for me. Note that your structure is
completely absurd. Also note that you should never use disk_io='high'
unless you have a good reason to.
