Detailed Description
template<class M, class I>
struct Dune::CommMatrixSparsityPattern< M, I >
struct Dune::CommMatrixSparsityPattern< M, I >
Utility class to communicate and build the sparsity pattern of a redistributed matrix.
- Template Parameters
-
M The type of the matrix that the sparsity pattern is communicated of. I The type of the index set.
Constructor & Destructor Documentation
◆ CommMatrixSparsityPattern() [1/2]
template<class M , class I >
|
inline |
Constructor for the original side.
- Parameters
-
m_ The matrix whose sparsity pattern is communicated. idxset_ The index set corresponding to the local matrix. aggidxset_ The index set corresponding to the redistributed matrix.
◆ CommMatrixSparsityPattern() [2/2]
template<class M , class I >
|
inline |
Constructor for the redistruted side.
- Parameters
-
m_ The matrix whose sparsity pattern is communicated. idxset_ The index set corresponding to the local matrix. aggidxset_ The index set corresponding to the redistributed matrix. rowsize_ The row size for the redistributed owner rows.
Member Function Documentation
◆ completeSparsityPattern()
template<class M , class I >
|
inline |
Completes the sparsity pattern of the redistributed matrix with data from copy rows for the novlp case.
After the pattern communication this function can be used.
- Parameters
-
add_sparsity Sparsity pattern from the copy rows.
References Dune::size().
◆ storeSparsityPattern()
template<class M , class I >
|
inline |
Creates and stores the sparsity pattern of the redistributed matrix.
After the pattern is communicated this function can be used.
- Parameters
-
m The matrix to build.
