Member Function Documentation

getAlltoAll()

FFTCommPattern Cabana::Grid::Experimental::FastFourierTransformParams::getAlltoAll ( ) const

inline

Get MPI communication strategy.

Returns

Using AllToAll or not.

getPencils()

bool Cabana::Grid::Experimental::FastFourierTransformParams::getPencils ( ) const

inline

Get data exchange type (pencil or slab).

Returns

Using pencil (true) or slab (false) decomposition.

getReorder()

bool Cabana::Grid::Experimental::FastFourierTransformParams::getReorder ( ) const

inline

Get data handling (contiguous or strided memory).

Returns

Using contiguous (true) or strided (false) memory layout. Contiguous layout requires tensor transposition; strided layout does not.

setAlltoAll() [1/2]

void Cabana::Grid::Experimental::FastFourierTransformParams::setAlltoAll ( bool value )

inline

Set MPI communication strategy.

Parameters

value

Use all to all MPI communication.

setAlltoAll() [2/2]

void Cabana::Grid::Experimental::FastFourierTransformParams::setAlltoAll ( FFTCommPattern value )

inline

Set MPI communication strategy.

Parameters

value

Use all to all MPI communication.

setPencils()

void Cabana::Grid::Experimental::FastFourierTransformParams::setPencils ( bool value )

inline

Set data exchange type (pencil or slab).

Parameters

value

Use pencil (true) or slab (false) decomposition.

setReorder()

void Cabana::Grid::Experimental::FastFourierTransformParams::setReorder ( bool value )

inline

Set data handling (contiguous or strided memory).

Parameters

value

Use contiguous (true) or strided (false) memory layout. Contiguous layout requires tensor transposition; strided layout does not.
