◆ localCopyAll()

void walberla::lbm::D3Q19StorageSpecification::PackKernels::localCopyAll	(	PdfField_T *	pdfs_src,
		CellInterval &	srcInterval,
		PdfField_T *	pdfs_dst,
		CellInterval &	dstInterval ) const

Copies data between two blocks on the same process.

All pdfs from the sending interval are copied onto the receiving interval.

◆ localCopyDirection()

void walberla::lbm::D3Q19StorageSpecification::PackKernels::localCopyDirection	(	PdfField_T *	pdfs_src,
		CellInterval &	srcInterval,
		PdfField_T *	pdfs_dst,
		CellInterval &	dstInterval,
		stencil::Direction	dir ) const

Copies data between two blocks on the same process.

PDFs streaming aligned with the direction dir are copied from the sending interval onto the receiving interval.

◆ packAll()

void walberla::lbm::D3Q19StorageSpecification::PackKernels::packAll	(	PdfField_T *	pdfs_src,
		CellInterval &	ci,
		unsigned char *	outBuffer ) const

Packs all pdfs from the given cell interval to the send buffer.

◆ packDirection()

void walberla::lbm::D3Q19StorageSpecification::PackKernels::packDirection	(	PdfField_T *	pdfs_src,
		CellInterval &	ci,
		unsigned char *	outBuffer,
		stencil::Direction	dir ) const

Packs only those populations streaming in directions aligned with the sending direction dir from the given cell interval.

For example, in 2D, if dir == N, the pdfs streaming in directions NW, N, NE are packed.

◆ size() [1/2]

uint_t walberla::lbm::D3Q19StorageSpecification::PackKernels::size ( CellInterval & ci ) const

inline

Returns the number of bytes that will be packed from / unpacked to the cell interval when using packAll / unpackAll.

Parameters

ci	The cell interval

Returns: The required size of the buffer, in bytes

◆ size() [2/2]

uint_t walberla::lbm::D3Q19StorageSpecification::PackKernels::size	(	CellInterval &	ci,
		stencil::Direction	dir ) const

inline

Returns the number of bytes that will be packed from / unpacked to the cell interval when using packDirection / unpackDirection.

Parameters

ci	The cell interval
dir	The communication direction

Returns: The required size of the buffer, in bytes

◆ unpackAll()

void walberla::lbm::D3Q19StorageSpecification::PackKernels::unpackAll	(	PdfField_T *	pdfs_dst,
		CellInterval &	ci,
		unsigned char *	inBuffer ) const

Unpacks all pdfs from the send buffer to the given cell interval.

◆ unpackDirection()

void walberla::lbm::D3Q19StorageSpecification::PackKernels::unpackDirection	(	PdfField_T *	pdfs_dst,
		CellInterval &	ci,
		unsigned char *	inBuffer,
		stencil::Direction	dir ) const

Unpacks only those populations streaming in directions aligned with the sending direction dir to the given cell interval.

For example, in 2D, if dir == N, the pdfs streaming in directions NW, N, NE are unpacked.
