[Pw_forum] Problem on paralle ph.x

[Zhufeng Hou]

Dear pwscf users:

Recently I have used pwscf2.1.3, which is complied on redhat 8.0 and by
PGI fortran 5.1 and mpich, to calculate the phonon of a compound. The
paralle pw.x works very well under PBS job queue system. But the paralle
ph.x exits after reading  the *.save file, and in the output file the
following information are printed:
-------------BEGIN--------------------------
 Program PHONON    v.2.1.3  starts ...
     Today is  1Sep2005 at 14:28:56

     Parallel version (MPI)

     Number of processors in use:       2
     R & G space division:  nprocp =    2

     Ultrasoft (Vanderbilt) Pseudopotentials

     nbndx  =    30  nbnd   =    30  natomwfc =    43  npwx   =     970
     nelec  =   38.00 nkb   =    60  ngl    =     188

---------------END----------------------

With the same inputs, the serial pw.x and ph.x works very well.

What is  wrong with the paralle ph.x?  How can I fixed it?

Your helps will be gratelly appricated!

Best wishes!
