Dear Vicky<br><br>Go in download package manager and just "type" there "mpich" , it will find the required files, which you install. It is very easy now. Thanks to developer for hard effort to make it easy. After installation of mpich, then you configure as you said before in mail. it will work fine.<br>

    Well, just take a look <a href="http://www.mcs.anl.gov/research/projects/mpich2/" target="_blank">here</a>
    or <a href="http://www.open-mpi.org/" target="_blank">here</a>.<br>
    I built it long time ago, I remember that was not difficult.<br>
    Check whether there is mpich2 or open-mpi package for your distro.<br>

            <br>
            if mpich (for instance) is installed, it will automatically
            detect it.<br>
            Then you will have to do <br>
            <br>
            <font color="#663366">mpiexec -n 4 path_to_qe_exec <
              input_file > out_file</font><br>
            <br>
            in order to use the 4 cores.<br>
            Note that this is well documented in the examples.<br>
            <br>
            The other solution is to build QE with  OpenMP, but I have
            not really tried.<br>
            Well, the only one tentative I did was unsuccessful.<br>
            <br>
            Hope it helps,<br>

                <div>Hi<br>
                  I have recently  got a new system with i5 processor.
                  Since it has 4 processor how can i install QE such
                  that i can run parallel processing. Documentation says
                  just to use ./configure and make to be done for
                  compiling. will these command when run will consider
                  the system configuration and install parallel version.<br>
                  <br>
                  Thanks for suggestion in advance.<br>
