[Pw_forum] parallel compilation

[Mahmoud Hammouri]

Hi all,
I'm trying to compile quantum espresso in parallel version, after using ./configure command i got this:
Parallel environment detected successfully.\
Configured for compilation of parallel executables.

After that I typed make all to get all executable which done without showing any errors. So I tried to run a relaxation system which is carbon nanotube using this command line:
mpirun -np 8 pw.x cnt.inp
Then,

Program PWSCF v.5.0.2 (svn rev. 9392) starts on  4Jun2013 at 10:32: 1

     This program is part of the open-source Quantum ESPRESSO suite
     for quantum simulation of materials; please cite

     Parallel version (MPI), running on     8 processors
     R & G space division:  proc/nbgrp/npool/nimage =       8

     Current dimensions of program PWSCF are:
     Max number of different atomic species (ntypx) = 10
     Max number of k-points (npk) =  40000
     Max angular momentum in pseudopotentials (lmaxx) =  3
     Waiting for input...
And it keep saying "waiting for input" for a very long time!!
I found a way to check the above which is : pw.x -inp and the input file name, but I got this error:

--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 0.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Can any one help me out.

Mahmoud
