    Well, just take a look <a
      href="http://www.mcs.anl.gov/research/projects/mpich2/">here</a>
    or <a href="http://www.open-mpi.org/">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>
    Remember that you have OpenMP on your machine ....<br>

            if mpich (for instance) is installed, it will automatically

            Then you will have to do <br>

              input_file &gt; out_file</font><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>

                  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>
