Detailed Description

This struct resembles a blocked csr matrix, like Dune::BCRSMatrix. The data is stored in contiguous memory, such that they can be copied to a device in one transfer.

Constructor & Destructor Documentation

BlockedMatrix() [1/3]

Opm::Accelerator::BlockedMatrix::BlockedMatrix ( int  Nb_, int  nnzbs_, unsigned int  block_size_  )

inline

Allocate BlockedMatrix and data arrays with given sizes

Parameters

[in]	Nb	number of blockrows
[in]	nnzbs	number of nonzero blocks
[in]	block_size	the number of rows and columns for each block

BlockedMatrix() [2/3]

Opm::Accelerator::BlockedMatrix::BlockedMatrix ( const BlockedMatrix &  M )

inline

Allocate BlockedMatrix, but copy sparsity pattern instead of allocating new memory

Parameters

[in]

M

matrix to be copied

BlockedMatrix() [3/3]

Opm::Accelerator::BlockedMatrix::BlockedMatrix ( int  Nb_, int  nnzbs_, unsigned int  block_size_, double *  nnzValues_, int *  colIndices_, int *  rowPointers_  )

inline

Allocate BlockedMatrix, but let data arrays point to existing arrays

Parameters

[in]	Nb	number of blockrows
[in]	nnzbs	number of nonzero blocks
[in]	block_size	the number of rows and columns for each block
[in]	nnzValues	array of nonzero values, contains nnzb*block_size*block_size scalars
[in]	colIndices	array of column indices, contains nnzb entries
[in]	rowPointers	array of row pointers, contains Nb+1 entries
