Function Documentation

Teuchos::RCP< Epetra_CrsGraph > Stokhos::adapt_utils::buildAdaptedGraph	(	const Epetra_CrsGraph &	determGraph,
		const Teuchos::RCP< const Stokhos::ProductBasis< int, double > > &	masterBasis,
		const std::vector< Teuchos::RCP< const Stokhos::ProductBasis< int, double > > > &	per_dof_row_basis,
		bool	onlyUseLinear = false,
		int	kExpOrder = -1
	)

Builds and returns an adapted graph given a set of row basis functions. This does all required global communication to construct this graph.

Teuchos::RCP< Epetra_Map > Stokhos::adapt_utils::buildAdaptedRowMapAndOffsets	(	const Epetra_Comm &	Comm,
		const std::vector< Teuchos::RCP< const Stokhos::ProductBasis< int, double > > > &	per_dof_row_basis,
		std::vector< int > &	myRowGidOffsets
	)

Construct a row map that is appropriate for the set of adapted basis functions.

Parameters

[in]	determGraph	Graph for the deterministic problem
[in]	per_dof_row_basis	Stochastic basis functions for each deterministic degree of freedom
[out]	myRowGidOffsets	Will be of length per_dof_row_basis.size() on exit. All data will be overwritten. This contains the starting GID of each deterministic degree of freedom.

Returns

The adapted row map.

Teuchos::RCP< Epetra_Map > Stokhos::adapt_utils::buildAdaptedRowMap	(	const Epetra_Comm &	Comm,
		const std::vector< Teuchos::RCP< const Stokhos::ProductBasis< int, double > > > &	per_dof_row_basis
	)

Construct a row map that is appropriate for the set of adapted basis functions.

void Stokhos::adapt_utils::buildAdaptedColOffsets	(	const Epetra_CrsGraph &	determGraph,
		const std::vector< int > &	myRowGidOffsets,
		std::vector< int > &	myColGidOffsets
	)

Build offsets mapping a local column id to a GID. Note that this function requires parallel communication (for parallel code).

Parameters

[in]	determGraph	Graph for the deterministic problem
[in]	myRowGidOffsets	Computed by buildAdaptedRowMapAndColOffsets
[out]	myRowGidOffsets	Will be of length determGraph.ColMap().NumMyElements() on exit. All data will be overwritten. This contains the starting GID of each deterministic degree of freedom in the column map.

void Stokhos::adapt_utils::buildColBasisFunctions	(	const Epetra_CrsGraph &	determGraph,
		const Teuchos::RCP< const Stokhos::ProductBasis< int, double > > &	masterBasis,
		const std::vector< Teuchos::RCP< const Stokhos::ProductBasis< int, double > > > &	per_dof_row_basis,
		std::vector< Teuchos::RCP< const Stokhos::ProductBasis< int, double > > > &	per_dof_col_basis
	)

Use the deterministic graph and the basis function on this processor to determine the basis functions for all the column entries on this processor. Note that this function requires parallel communication (for parallel code).

Parameters

[in]	determGraph	Graph for the deterministic problem
[in]	per_dof_row_basis	Stochastic basis functions for each deterministic degree of freedom
[out]	per_dof_col_basis	Stochastic basis functions for each degree of freedom in the deterministic column map.
