Detailed Description

template<typename T>
class fei::Vector_Impl< T >

To be used for vector data assembly, including local assembly of shared data. Provides operations for gathering the overlapped data (locally- stored shared data) to a non-overlapped data distribution (e.g., send shared data to owning processor) and vice-versa for scattering non- overlapped data to the overlapped distribution.

When shared data that is not locally-owned is assembled into this object, it will be held locally until the gatherFromOverlap() operation is performed. When data that is locally-owned is assembled into this object, it will be passed directly to the underlying algebraic (non-overlapping) vector.

When non-locally-owned shared data is requested from this vector object, the operation is only guaranteed to succeed if scatterToOverlap() has been called. If non-local data has recently been input to this vector, but the vector has not been 'synchronized' using gatherFromOverlap() and scatterToOverlap(), then that data may be used to answer the request but the values may be erroneous due to not including contributions from other processors.

Member Function Documentation

template<typename T>

const char* fei::Vector_Impl< T >::typeName ( ) const

inlinevirtual

  Return a name describing the run-time type

of this object.

Implements fei::Vector.

Definition at line 72 of file fei_Vector_Impl.hpp.

template<typename T >

int fei::Vector_Impl< T >::update	(	double	a,

Implements fei::Vector.

Definition at line 323 of file fei_Vector_Impl.hpp.

template<typename T >

int fei::Vector_Impl< T >::scatterToOverlap ( )

virtual

  Use data in the underlying non-overlapping decomposition to update

any shared data in the overlapping decomposition.

If any data is already held for the shared positions, that data will be replaced by the data from the 'owning' processor.

Implements fei::Vector.

Definition at line 339 of file fei_Vector_Impl.hpp.

template<typename T >

void fei::Vector_Impl< T >::setCommSizes ( )

virtual

perform initial communication to establish message sizes that will be needed for exchanging shared-node data. Called from within gatherFromOverlap usually, doesn't usually need to be explicitly called by client code. (Power users only...)

Implements fei::Vector.

Definition at line 351 of file fei_Vector_Impl.hpp.

template<typename T >

int fei::Vector_Impl< T >::gatherFromOverlap ( bool accumulate = true )

virtual

  Move any shared data from the overlapping decomposition to the

underlying non-overlapping decomposition.

Implements fei::Vector.

Definition at line 363 of file fei_Vector_Impl.hpp.

template<typename T >

int fei::Vector_Impl< T >::putScalar ( double scalar )

virtual

Set a specified scalar throughout the vector.

Implements fei::Vector.

Definition at line 301 of file fei_Vector_Impl.hpp.

template<typename T >

int fei::Vector_Impl< T >::sumIn	(	int	numValues,
		const int *	indices,
		const double *	values,
		int	vectorIndex = `0`
	)

virtual

  Sum values into the vector, adding to any

that may already exist at the specified indices.

Implements fei::Vector.

Definition at line 375 of file fei_Vector_Impl.hpp.

template<typename T >

int fei::Vector_Impl< T >::copyIn	(	int	numValues,
		const int *	indices,
		const double *	values,
		int	vectorIndex = `0`
	)

virtual

  Copy values into the vector, overwriting any that may already exist

at the specified indices.

Implements fei::Vector.

Definition at line 389 of file fei_Vector_Impl.hpp.

template<typename T>

fei::SharedPtr<fei::VectorSpace> fei::Vector_Impl< T >::getVectorSpace ( ) const

inlinevirtual

Obtain the VectorSpace associated with this vector.

Implements fei::Vector.

Definition at line 112 of file fei_Vector_Impl.hpp.

template<typename T>

void fei::Vector_Impl< T >::setVectorSpace ( fei::SharedPtr< fei::VectorSpace > vecSpace )

inlinevirtual

Set the VectorSpace associated with this vector.

Implements fei::Vector.

		int	idType,
		int	numIDs,
		const int *	IDs,
		const double *	data,
		int	vectorIndex = `0`
	)

virtual

  Sum field data into the vector, adding to any coefficients that may

already exist at the specified locations. If the specified fieldID doesn't exist at one or more of the specified IDs, then the corresponding positions in the data array will simply not be used.

Implements fei::Vector.

  Copy field data into the vector, overwriting any coefficients that may

already exist at the specified locations. If the specified fieldID doesn't exist at one or more of the specified IDs, then the corresponding positions in the data array will simply not be used.

		int	vectorIndex = `0`
	)

virtual

  Copy field data out of the vector, into the caller-allocated data

array. If the specified fieldID doesn't exist at one or more of the specified IDs, then the corresponding positions in the data array will simply not be referenced.

virtual

  Write the vector's contents into the specified file.

Parameters

filename	Text name of the file to be created or overwritten. If in a parallel environment, each processor will take turns writing into the file.
matrixMarketFormat	Optional argument, defaults to true. If true the contents of the file will be MatrixMarket real array format. If not true, the contents of the file will contain the vector's global dimension on the first line, and all following lines will contain a space-separated pair with global index first and coefficient value second.

Returns: error-code 0 if successful, -1 if some error occurs such as failure to open file.

Parameters

ostrm	ostream to be written to.
matrixMarketFormat	Optional argument, defaults to true. If true the contents of the vector will be written in MatrixMarket real array format.
