Openmpi different head file: use mpi ,mpif.h ,mpi,h

when i use different openmpi’s headfile , compiling program produce different result , and i want to know which headfile(mpi ,mpif.h ,mpi,h) is best one when using the cuda with openmpi on linux. the follow is code

program cartesian
implicit none
include ‘mpif.h’ ! use this compile is ok
!include ‘mpi.h’ ! use one compile is erorr
!use mpi ! use one : the implicit none must be Beneath it and print Could && not resolve generic procedure mpi_cart_create
