Detailed Description

The scatterer registry class.

Scatterings between arbitrary numberings and parallel layouts can be registered for later access.

Template Parameters

T	Integer type.

Definition at line 755 of file SF_abstract_vector.h.

Member Function Documentation

free_scatterings()

void SF::scatter_registry::free_scatterings ( )

inline

Free the registered scatterings.

Definition at line 914 of file SF_abstract_vector.h.

Here is the caller graph for this function:

get_scattering()

scattering* SF::scatter_registry::get_scattering ( const quadruple< int >  spec )

inline

Access an previously registered scattering.

Parameters

[in]	spec	Scattering specification, see register routines.
[out]	use_forward	If the scattering was found, this is true. If only the transposed scattering was found this is false and the returned scattering has to be used transposed.

Returns

The requested scattering.

Definition at line 900 of file SF_abstract_vector.h.

Here is the caller graph for this function:

register_permutation()

template<class T >

scattering* SF::scatter_registry::register_permutation ( const quadruple< int >  spec, const vector< T > &  nbr_a, const vector< T > &  nbr_b, const size_t  gsize_a, const size_t  gsize_b, const short  dpn  )

inline

Register a permutation scattering.

Parameters

[in]	spec	The spec specifies: v1 = mesh ID, v2 = permutation type, v3 = numbering, v4 = dpn
[in]	nbr_a	Nodal numbering of "a" side.
[in]	nbr_b	Nodal numbering of "b" side.
[in]	gsize_a	Global nodal size of "a" side.
[in]	gsize_b	Global nodal size of "b" side.
[in]	dpn	Degrees of freedom per node index.

Postcondition

Scattering has been registered and set up.
