integer	variables_mpi::rank = 0
	Rank for the current local domain (associated to an MPI process).
type(mpi_comm)	variables_mpi::mpi_comm_notus

These variables are set ONLY IF there are more than one proc in the given direction. Example 1: 'is_proc_on_left_periodic == .false.' if 'is_periodic_x == .true.' and 'n_mpi_proc_x == 1'.
