[Pw_forum] espresso 4 _ parallel

[loc duong ding]

Dear Users, 


I use Mpich2 to run Quantum Epresso code. I have a error when I try to run execute file pw.x.

>>mpiexec -machinefile  /home/loc/machinefile -n 8 pw.x -npool 2  < input_Graphite_GGA > output_Graphite_GGA2 &

application called MPI_Abort(MPI_COMM_WORLD, 0) - process 1
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 3[cli_3]: aborting job                   :
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 3
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 7[cli_7]: aborting job                   :
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 7
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 2[cli_2]: aborting job                   :
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 2
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 6[cli_6]: aborting job                   :
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 6
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 5[cli_5]: aborting job                   :
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 5
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 4[cli_4]: aborting job                   :
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 4

In the output file, the error is: 

rank 7 in job 2  master_49510   caused collective abort of all ranks
  exit status of rank 7: return code 0
rank 3 in job 2  master_49510   caused collective abort of all ranks
  exit status of rank 3: return code 0
rank 1 in job 2  master_49510   caused collective abort of all ranks
  exit status of rank 1: return code 0


I tried to test mpiexec command whith some another execute file and there was no problem. The pw.x is also ok when it was run alone (serial running). 

Please give me some suggestion for this error. I also saw this problem in PW_forum but I can find the solution for it.

Best regards,
Duong Dinh Loc.
