Actually MPI_Init is in

Furthermore, I tried man mpicc
/usr/share/man/mpich-x86_64/man1/mpicc.1.gz
/usr/share/man/openmpi-x86_64/man1/mpicc.1.gz
But it does not work
You don't wnat to use the OpenMPI headers to compile something with
mpich. As has been said, install the mpich-devel package, which has
its own headers in /usr/include/mpich-x86_64/ that defined MPI_Init,
and don't forget to load the environment module first!
