Lyuwen's Instruction for Compilation
************************************

#. This package is very simple to configure, just run the following command

.. code-block:: bash

     ./configure \
         MPIF90=mpiifort \
         --prefix=${HOME} \
         --with-scalapack=intel \
         FFT_LIBS=${HOME}/lib/libfftw3xf_intel.a \
         --enable-parallel #--enable-openmpi # since we are using impi or mpich

The configure code will figure out the intel composer in our in-house cluster. But for Habanero and Yeti, it seems it only able to reads automatically from intel-parallel-studio/2015, one may specify ``SCALAPACK_LIBS = -lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64`` for intel-parallel-studio/2017 to use scalapack. One can easily check the libraries linked after compilation by using ``ldd`` command.

#. Compiling everything

.. code-block:: bash
   
     make all


#. Compiling some part of the quantum espresso, you can find instrunctions by simply type make. The command for compiling only PWscf and PHonon is as follows

.. code-block:: bash
   
     make pw ph

#. Currently Quantum ESPRESSO does not support force computation for LDA+U. Thus, relaxation and phonon computation is impossble for now.
