Amin,
In addition to Axel's suggustions, you may need to add -D__MPI option too.

Dear friends
I am so sorry for this but i couldn't solve my problem.
i installed lam 7.1.2 in my computer and i didn't change the installation PATH.
after that i configure the espresso.this file has been made.

i saw that for mpif90 and F77, ifort compiler want to use so i change all of them to mpif77. and i compiled it.by doing that i could use both of my computer's cpu but this error was hapen at the end of my runs.
It seems that [at least] one of the processes that was started with
mpirun did not invoke MPI_INIT before quitting (it is possible that
more than one process did not invoke MPI_INIT -- mpirun was only
notified of the first one, which was on node n0).
mpirun can *only* be used with MPI programs (i.e., programs that
invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program
to run non-MPI programs over the lambooted nodes.
-----------------------------------------------------------------------------
forrtl: error (78): process killed (SIGTERM)
mpirun failed with exit status 252
my computer run both of cpus but he didn't share kpoint he only do the same job with both cpus.
please help me i really confused why it happended.
sincerely yours

Amin,
Sorry, I was out of the town and had no access to my e-mail.
1. You can use anyone of MPI implemetations. But I recommend Intel MPI-2 because it's an
installable binary, it saves you as a beginner a lot of time. If you cannot get a copy of that,
use OpenMPI, a successor of LAM/MPI.
2. Basically, when you recompile MPI, you can add --prefix=/your/favourite/place to configure
3. You need C compiler to compile MPI. You need gcc too. I compiled MPI with icc + ifort.
Good luck!

Thanks a lot for your answers.but until yet i couldn't solve my problem.I confused about mpi. there are three kind of mpi in the Internet (lam/mpi,openmpi,mpich) i don't know which one of them i should install.
about making the environment i should say that i am beginner in using Linux so i use the ./configure commend and i didn't change any path because i don't know how i should do it.
i will appreciate if answer my question?
1-which mpi do i need for my job?
2-how could i change the path?
3-is ifort compiler enough for installing mpi package?
Thanks a lot

Have you set up you environment for using one the mpi libraries you installed in .bashrc?
For example, for openmpi you need to set following in your .bashrc if you are using bash
as your shell:
...
export PATH=/opt/openmpi/bin:$PATH
export LD_LIBRARY_PATH=/opt/openmpi/lib:$LD_LIBRARY_PATH
...
Note: you need to replace /opt/openmpi with the path of your installation.

Dear Dr.Kohlmeyer
Thanks a lot for your help.I did what you said.i installed
fftw-3.1.2.tar
lam-7.1.2.tar
mpich2-1.0.4p1.tar
openmpi-1.1.2.tar
on fedora core 5 and after that i configure the espresso but this error was written
WARNING: the following problems were detected:
unsupported C/Fortran compilers combination:
CC=mpicc, F77=mpif77, F90=mpif90
you may not be able to compile this program.
i don't know what this problem means.would you please help me.
Thanks a lot

you have to install an MPI package (e.g. LAM/MPI, OpenMPI, MPICH)
first and then configure/compile quantum espresso with parallel support
as explained in the provided installation instructions.
please make sure that your MPI package is compatible with or compiled
for the fortran compiler you want to use to compiled quantum espresso with.
precompiled packages may be compiled for a different compiler and thus
need special flags or environment variables set to use the compiler of
your choice.
