   Thanks to Eyvaz's advice. I have succeeded to compile the pwscf code.

  Sorry for my stupid question, till now I did not konw clear about
and how to describe the  the network. And you are  right "OpenMPI is
not going to change that!", although the openmpi performance better
than mpich2. I think the pwscf with openmpi have reached my
expectancy.

   Thanks again.
    Bests.
