Detailed Description

template<typename scalar_t>
class strumpack::DistributedMatrixWrapper< scalar_t >

Wrapper class does exactly the same as a regular DistributedMatrix, but it is initialized with existing memory, so it does not allocate, own or delete the memory

Member Function Documentation

◆ cols()

template<typename scalar_t >

int strumpack::DistributedMatrixWrapper< scalar_t >::cols ( ) const

inlineoverridevirtual

Get the number of global rows in the matrix

Returns: Global number of matrix columns

Reimplemented from strumpack::DistributedMatrix< scalar_t >.

◆ hconcat()

template<typename scalar_t >

void strumpack::DistributedMatrixWrapper< scalar_t >::hconcat ( const DistributedMatrix< scalar_t > & b )

inlineoverridevirtual

Reimplemented from strumpack::DistributedMatrix< scalar_t >.

◆ I()

template<typename scalar_t >

int strumpack::DistributedMatrixWrapper< scalar_t >::I ( ) const

inlineoverridevirtual

Row index of top left element. This is always 1 for a DistributedMatrix. For a DistributedMatrixWrapper, this can be different from to denote the position in the original matrix.

Returns: Row index of top left element (1-based).

Reimplemented from strumpack::DistributedMatrix< scalar_t >.

◆ J()

template<typename scalar_t >

int strumpack::DistributedMatrixWrapper< scalar_t >::J ( ) const

inlineoverridevirtual

Columns index of top left element. This is always 1 for a DistributedMatrix. For a DistributedMatrixWrapper, this can be different from to denote the position in the original matrix.

Returns: Column index of top left element (1-based).

Reimplemented from strumpack::DistributedMatrix< scalar_t >.

◆ lranges()

template<typename scalar_t >

void strumpack::DistributedMatrixWrapper< scalar_t >::lranges	(	int &	rlo,
		int &	rhi,
		int &	clo,
		int &	chi
	)		const

overridevirtual

Get the ranges of local rows and columns. For a DistributedMatrix, this will simply be (0, lrows(), 0, lcols()). For a DistributedMatrixWrapper, this returns the local rows/columns of the DistributedMatrix that correspond the the submatrix represented by the wrapper. The values are 0-based

Parameters

rlo	output parameter, first local row
rhi	output parameter, one more than the last local row
clo	output parameter, first local column
chi	output parameter, one more than the last local column

Reimplemented from strumpack::DistributedMatrix< scalar_t >.

◆ memory()

template<typename scalar_t >

std::size_t strumpack::DistributedMatrixWrapper< scalar_t >::memory ( ) const

inlineoverridevirtual

Reimplemented from strumpack::DistributedMatrix< scalar_t >.

◆ nonzeros()

template<typename scalar_t >

std::size_t strumpack::DistributedMatrixWrapper< scalar_t >::nonzeros ( ) const

inlineoverridevirtual

Reimplemented from strumpack::DistributedMatrix< scalar_t >.

◆ resize()

template<typename scalar_t >

void strumpack::DistributedMatrixWrapper< scalar_t >::resize	(	std::size_t	m,
		std::size_t	n
	)

inlineoverridevirtual

Reimplemented from strumpack::DistributedMatrix< scalar_t >.

◆ rows()

template<typename scalar_t >

int strumpack::DistributedMatrixWrapper< scalar_t >::rows ( ) const

inlineoverridevirtual

Get the number of global rows in the matrix

Returns: Global number of matrix rows

Reimplemented from strumpack::DistributedMatrix< scalar_t >.

◆ total_memory()

template<typename scalar_t >

std::size_t strumpack::DistributedMatrixWrapper< scalar_t >::total_memory ( ) const

inlineoverridevirtual

Reimplemented from strumpack::DistributedMatrix< scalar_t >.

◆ total_nonzeros()

template<typename scalar_t >

std::size_t strumpack::DistributedMatrixWrapper< scalar_t >::total_nonzeros ( ) const

inlineoverridevirtual

Reimplemented from strumpack::DistributedMatrix< scalar_t >.
