[Pw_forum] installing QE

[vicky singh]

Dear PWSCF users

Thanks for advising to install mpich. I installed mpich2 in my machine and
the i ran the espresso-4.3_examples. Many programme were succesfully done
but may came out with error.

Foe eg.
/home/Software/espresso-4.3_examples/examples/example14 : starting

This example shows how to use pw.x, ph.x and d3.x to calculate the
third-order expansion coefficients of the total energy of Si.

  executables directory: /home/Software/espresso-4.3/bin
  pseudo directory:      /home/Software/pseudo
  temporary directory:   ./tmp
  checking that needed directories and files exist... done

  running pw.x as: mpirun -np 4  /home/Software/espresso-4.3/bin/pw.x
  running ph.x as: mpirun -np 4  /home/Software/espresso-4.3/bin/ph.x
  running d3.x as: mpirun -np 4  /home/Software/espresso-4.3/bin/d3.x

  cleaning ./tmp... done
  running the scf calculation for Si... done
  running the phonon calculation for Si at Gamma...application called
MPI_Abort(MPI_COMM_WORLD, 0) - process 1
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 3
application called MPI_Abort(MPI_COMM_WORLD, 0) - process 0
Error condition encountered during test: exit status = 15
Aborting

many eg (15,18, ..) showed the same error. what can be the possible error.

thanks in advance
