Detailed Description

template<class T>
class SF::parallel_layout< T >

The base class for parallel layouts.

It provides the basic index localization and globalization functionality.

Template Parameters

T	Integer type.

Member Function Documentation

assign()

template<class T >

void SF::parallel_layout< T >::assign ( const vector< T > &  idx )

inline

Assign a parallel distributed index set that defines the parallel layout.

Parameters

idx	An vector holding the global indices of the local domain.

Definition at line 359 of file SF_parallel_layout.h.

Here is the caller graph for this function:

globalize() [1/2]

template<class T >

T SF::parallel_layout< T >::globalize ( const T  lidx ) const

inline

Globalize local indices.

Indices that cannot be mapped will be removed.

Parameters

lvec	The indices to globalize.

Precondition

lvec contains local indices.

Postcondition

lvec contains global indices.

Definition at line 276 of file SF_parallel_layout.h.

globalize() [2/2]

template<class T >

void SF::parallel_layout< T >::globalize ( vector< T > &  lvec ) const

inline

Globalize local indices.

Indices that cannot be mapped will be removed.

Parameters

lvec	The indices to globalize.

Precondition

lvec contains local indices.

Postcondition

lvec contains global indices.

Definition at line 254 of file SF_parallel_layout.h.

localize() [1/3]

template<class T >

T SF::parallel_layout< T >::localize ( T  gidx ) const

inline

Definition at line 345 of file SF_parallel_layout.h.

localize() [2/3]

template<class T >

template<class V >

void SF::parallel_layout< T >::localize ( vector< T > &  gidx, vector< V > &  gdat  ) const

inline

Localize global indices and associated data.

Indices and data that cannot be mapped will be removed.

Template Parameters

V	Value type. Can be anything with a proper '=' operator.

Parameters

gidx	The indices to localize.
gdat	The data to localize.

Precondition

gidx contains global indices and gdat the associated data.

Postcondition

gidx contains local indices and gdat the associated data.

Definition at line 326 of file SF_parallel_layout.h.

localize() [3/3]

template<class T >

void SF::parallel_layout< T >::localize ( vector< T > &  gvec ) const

inline

Localize global indices.

Indices that cannot be mapped will be removed.

Parameters

gvec	The indices to localize.

Precondition

gvec contains global indices.

Postcondition

gvec contains local indices.
