Functions and subroutines

pass_vector_start_2d()

integer function mom_domains::pass_vector_start::pass_vector_start_2d ( real, dimension(:,:), intent(inout)  u_cmpt, real, dimension(:,:), intent(inout)  v_cmpt, type(mom_domain_type), intent(inout)  MOM_dom, integer, intent(in), optional  direction, integer, intent(in), optional  stagger, logical, intent(in), optional  complete, integer, intent(in), optional  halo, integer, intent(in), optional  clock  )

pass_vector_start_2d starts a halo update for a pair of two-dimensional arrays representing the compontents of a two-dimensional horizontal vector.

Parameters

[in,out]	u_cmpt	The nominal zonal (u) component of the vector pair which is having its halos points exchanged.
[in,out]	v_cmpt	The nominal meridional (v) component of the vector pair which is having its halos points exchanged.
[in,out]	mom_dom	The MOM_domain_type containing the mpp_domain needed to determine where data should be sent.
[in]	direction	An optional integer indicating which directions the data should be sent. It is TO_ALL or the sum of any of TO_EAST, TO_WEST, TO_NORTH, and TO_SOUTH, possibly plus SCALAR_PAIR if these are paired non-directional scalars discretized at the typical vector component locations. For example, TO_EAST sends the data to the processor to the east, so the halos on the western side are filled. TO_ALL is the default if omitted.
[in]	stagger	An optional flag, which may be one of A_GRID, BGRID_NE, or CGRID_NE, indicating where the two components of the vector are discretized. Omitting stagger is the same as setting it to CGRID_NE.
[in]	complete	An optional argument indicating whether the halo updates should be completed before progress resumes. Omitting complete is the same as setting complete to .true.
[in]	halo	The size of the halo to update - the full halo by default.
[in]	clock	The handle for a cpu time clock that should be started then stopped to time this routine.

Returns

The integer index for this update.
