Detailed Description

Function Documentation

swapLocalRow()

template<typename scalar_t >

void slate::swapLocalRow	(	int64_t	j_offset,
		int64_t	n,
		Tile< scalar_t > &	A,
		int64_t	i1,
		Tile< scalar_t > &	B,
		int64_t	i2
	)

Swap a partial row of two local tiles: A[ i1, j_offset : j_offset+n-1 ] and B[ i2, j_offset : j_offset+n-1 ].

Either or both tiles can be transposed to swap columns.

swapRemoteRow()

template<typename scalar_t >

void slate::swapRemoteRow	(	int64_t	j,
		int64_t	n,
		Tile< scalar_t > &	A,
		int64_t	i,
		int	other_rank,
		MPI_Comm	mpi_comm,
		int	tag = 0
	)

Swap a partial row, A[ i, j : j+n-1 ], with another MPI process.

The tile can be transposed to swap a column.

swapRemoteRowDevice()

template<typename scalar_t >

void slate::swapRemoteRowDevice	(	int64_t	j,
		int64_t	n,
		int	device,
		Tile< scalar_t > &	A,
		int64_t	i,
		int	other_rank,
		MPI_Comm	mpi_comm,
		blas::Queue &	queue,
		int	tag = 0
	)

Swap a partial row, A[ i, j : j+n-1 ], on a GPU device, with another MPI process.

The tile must be row-major, and cannot be transposed.
