To generate the MPI/OpenMP hybrid version, all you have to do 
   is to include a compiler option for OpenMP parallelization for CC and FC
   in 'makefile' in the directory 'source'. 
   To proceed the installation of the MPI/OpenMP version, move to the directory 'source', 
   and specify CC, FC and LIB in 'makefile', for example,  as follows:
For icc
   
     CC    = mpicc -openmp -O3 -I/usr/local/include
     FC    = mpif90 -openmp -O3 -I/usr/local/include
     LIB   = -L/usr/local/lib -lfftw3 -llapack -lblas -lg2c -static
   
     CC    = mpicc -mp -O3 -I/usr/local/include
     FC    = mpif90 -mp -O3 -I/usr/local/include
     LIB   = -L/usr/local/lib -lfftw3 -llapack -lblas -lg2c -static
   
     % make install
   
When the compilation is completed normally, then you can
   find the executable file 'openmx' in the directory 'work'. 
   To make the execution of OpenMX efficient, you can change a compiler and
   compile options appropriate for your computer environment, 
   which can generate an optimized executable file.
