[Pw_forum] Problem with parallel running by mpich2

Dear developers and all users,

I use MPICH2 to run PWSCF. I get a problem. When I run PWSCF by command:

mpiexec -machinefile /home/loc/machinefile -n 8 pw.x -npool 2 <C8OOH_11.txt >test

there is nothing: No error, no announcement. 
When I test the input file ( C8OOH_11.txt) by command:

pw.x  <C8OOH_11.txt >test
 
it runs well even though very slow. 
 
To test MPICH2, I use that to run another small structure and no problem.
 
Have any one met this problem? What is the possible reason of this problem?
 
This is my input file:
