Detailed Description

Epetra_CrsMatrix: A class for constructing and using real-valued double-precision sparse compressed row matrices.

The Epetra_CrsMatrix class is a sparse compressed row matrix object. This matrix can be

used in a parallel setting, with data distribution described by Epetra_Map attributes. The structure or graph of the matrix is defined by an Epetra_CrsGraph attribute.

In addition to coefficient access, the primary operations provided by Epetra_CrsMatrix are matrix times vector and matrix times multi-vector multiplication.

Epetra_CrsMatrix matrices can be square or rectangular.

Creating and filling Epetra_CrsMatrix objects

Constructing Epetra_CrsMatrix objects is a multi-step process. The basic steps are as follows:

Create Epetra_CrsMatrix instance, including storage, via one of the constructors:
- Constructor that accepts one Epetra_Map object, a row-map defining the distribution of matrix rows.
- Constructor that accepts two Epetra_Map objects. (The second map is a column-map, and describes the set of column-indices that appear in each processor's portion of the matrix. Generally these are overlapping sets – column-indices may appear on more than one processor.)
- Constructor that accepts an Epetra_CrsGraph object, defining the non-zero structure of the matrix.
Note that the constructors which accept Epetra_Map arguments also accept an argument that gives an estimate of the number of nonzeros per row. This allows storage to be pre-allocated and can improve the performance of the data input methods. The estimate need not be accurate, as additional storage is allocated automatically when needed. However, a more accurate estimate helps performance by reducing the amount of extra memory allocation.
Enter values via one or more Insert/Replace/SumInto functions.
Complete construction by calling FillComplete.

Note that, even after a matrix is constructed (FillComplete has been called), it is possible to update existing matrix entries. It is not possible to create new entries.

Epetra_Map attributes

Epetra_CrsMatrix objects have four Epetra_Map attributes, which are held by the Epetra_CrsGraph attribute.

The Epetra_Map attributes can be obtained via these accessor methods:

RowMap() Describes the numbering and distribution of the rows of the matrix. The row-map exists and is valid for the entire life of the matrix. The set of matrix rows is defined by the row-map and may not be changed. Rows may not be inserted or deleted by the user. The only change that may be made is that the user can replace the row-map with a compatible row-map (which is the same except for re-numbering) by calling the ReplaceRowMap() method.
ColMap() Describes the set of column-indices that appear in the rows in each processor's portion of the matrix. Unless provided by the user at construction time, a valid column-map doesn't exist until FillComplete() is called.
RangeMap() Describes the range of the matrix operator. e.g., for a matrix-vector product operation, the result vector's map must be compatible with the range-map of this matrix. The range-map is usually the same as the row-map. The range-map is set equal to the row-map at matrix creation time, but may be specified by the user when FillComplete() is called.
DomainMap() Describes the domain of the matrix operator. The domain-map can be specified by the user when FillComplete() is called. Until then, it is set equal to the row-map.

It is important to note that while the row-map and the range-map are often the same, the column-map and the domain-map are almost never the same. The set of entries in a distributed column-map almost always form overlapping sets, with entries being associated with more than one processor. A domain-map, on the other hand, must be a 1-to-1 map, with entries being associated with only a single processor.

Local versus Global Indices

Epetra_CrsMatrix has query functions IndicesAreLocal() and IndicesAreGlobal(), which are used to determine whether the underlying Epetra_CrsGraph attribute's column-indices have been transformed into a local index space or not. (This transformation occurs when the method Epetra_CrsGraph::FillComplete() is called, which happens when the method Epetra_CrsMatrix::FillComplete() is called.) The state of the indices in the graph determines the behavior of many Epetra_CrsMatrix methods. If an Epetra_CrsMatrix instance is constructed using one of the constructors that does not accept a pre-existing Epetra_CrsGraph object, then an Epetra_CrsGraph attribute is created internally and its indices remain untransformed (IndicesAreGlobal()==true) until Epetra_CrsMatrix::FillComplete() is called. The query function Epetra_CrsMatrix::Filled() returns true if Epetra_CrsMatrix::FillComplete() has been called.

Note the following method characteristics:

InsertGlobalValues() may only be used to insert new nonzeros in the matrix if indices are global.
SumIntoGlobalValues() may be used regardless of whether indices are global or local, but can only be used to update matrix locations that already exist; it can never be used to establish new nonzero locations.
ReplaceGlobalValues() may also be used only to update matrix locations that already exist, and works regardless of whether indices are local or global.
SumIntoMyValues() and ReplaceMyValues() may only be used if indices are local.
Multiply() may only be used after FillComplete() has been called.

Most methods have preconditions documented, check documentation for specific methods not mentioned here.

Counting Floating Point Operations

Each Epetra_CrsMatrix object keeps track of the number of serial floating point operations performed using the specified object as the this argument to the function. The Flops() function returns this number as a double precision number. Using this information, in conjunction with the Epetra_Time class, one can get accurate parallel performance numbers. The ResetFlops() function resets the floating point counter.

Warning: A Epetra_Map is required for the Epetra_CrsMatrix constructor.

Parameters

CV	- (In) An Epetra_DataAccess enumerated type set to Copy or View.
RowMap	- (In) An Epetra_Map defining the numbering and distribution of matrix rows.

		const Epetra_Import &	RowImporter,
		const Epetra_Map *	DomainMap = `0`,
		const Epetra_Map *	RangeMap = `0`,
		bool	RestrictCommunicator = `false`
	)

Epetra CrsMatrix constructor that also fuses Import and FillComplete().

A common use case is to create an empty destination Epetra_CrsMatrix, redistribute from a source CrsMatrix (by an Import or Export operation), then call FillComplete() on the destination CrsMatrix. This constructor fuses these three cases, for an Import redistribution.

Fusing redistribution and FillComplete() exposes potential optimizations. For example, it may make constructing the column map faster, and it may avoid intermediate unoptimized storage in the destination Epetra_CrsMatrix. These optimizations may improve performance for specialized kernels like sparse matrix-matrix multiply, as well as for redistributing data after doing load balancing.

The resulting matrix is fill complete (in the sense of Filled()) and has optimized storage (in the sense of StorageOptimized()). It the DomainMap is taken from the SourceMatrix, the RangeMap is presumed to be RowImporter.TargetMap() if not specified

Parameters

SourceMatrix	[in] The source matrix from which to import. The source of an Import must have a nonoverlapping distribution.
RowImporter	[in] The Import instance containing a precomputed redistribution plan. The source Map of the Import must be the same as the row Map of sourceMatrix.
DomainMap	[in] The new domainMap for the new matrix. If not specified, then the DomainMap of the SourceMatrix is used.

int Epetra_CrsMatrix::InsertGlobalValues	(	int	GlobalRow,
		int	NumEntries,
		const double *	Values,
		const int *	Indices
	)

virtual

Insert a list of elements in a given global row of the matrix.

This method is used to construct a matrix for the first time. It cannot be used if the matrix structure has already been fixed (via a call to FillComplete()). If multiple values are inserted for the same matrix entry, the values are initially stored separately, so memory use will grow as a result. However, when FillComplete is called the values will be summed together and the additional memory will be released.

For example, if the values 2.0, 3.0 and 4.0 are all inserted in Row 1, Column 2, extra storage is used to store each of the three values separately. In this way, the insert process does not require any searching and can be faster. However, when FillComplete() is called, the values will be summed together to equal 9.0 and only a single entry will remain in the matrix for Row 1, Column 2.

Parameters

GlobalRow	- (In) Row number (in global coordinates) to put elements.
NumEntries	- (In) Number of entries.
Values	- (In) Values to enter.
Indices	- (In) Global column indices corresponding to values.

Returns: Integer error code, set to 0 if successful. Note that if the allocated length of the row has to be expanded, a positive warning code will be returned.

Warning: This method may not be called once FillComplete() has been called.

int Epetra_CrsMatrix::OptimizeStorage ( )

Make consecutive row index sections contiguous, minimize internal storage used for constructing graph.

After construction and during initialization (when values are being added), the matrix coefficients for each row are managed as separate segments of memory. This method moves the values for all rows into one large contiguous array and eliminates internal storage that is not needed after matrix construction. Calling this method can have a significant impact on memory costs and machine performance.

If this object was constructed in View mode then this method can't make non-contiguous values contiguous and will return a warning code of 1 if the viewed data isn't already contiguous.

Note: A call to this method will also call the OptimizeStorage method for the associated Epetra_CrsGraph object. If the storage for this graph has already been optimized this additional call will have no effect.

Returns: Integer error code, set to 0 if successful.

Precondition: Filled()==true.; If CV=View when the graph was constructed, then this method will be effective only if the indices of the graph were already contiguous. In this case, the indices are left untouched and internal storage for the graph is minimized.

Postcondition: StorageOptimized()==true, if successful.; Graph().StorageOptimized()==true, if successful.

Computes the inverse of the sum of absolute values of the rows of the Epetra_CrsMatrix, results returned in x.

The vector x will return such that x[i] will contain the inverse of the sum of the absolute values of the entries in the ith row of the this matrix. Using the resulting vector from this function as input to LeftScale() will make the infinity norm of the resulting matrix exactly 1.

Warning: The NormInf() method will not properly calculate the infinity norm for a matrix that has entries that are replicated on multiple processors. In this case, if the rows are fully replicated, NormInf() will return a value equal to the maximum number of processors that any individual row of the matrix is replicated on.

Parameters

x	- (Out) An Epetra_Vector containing the inverse of the row sums of the this matrix.

Warning: When rows are fully replicated on multiple processors, it is assumed that the distribution of x is the same as the rows (RowMap())of this. When multiple processors contain partial sums for individual entries, the distribution of x is assumed to be the same as the RangeMap() of this.

int Epetra_CrsMatrix::SortGhostsAssociatedWithEachProcessor ( bool Flag )

inline

Forces FillComplete() to locally order ghostnodes associated with each remote processor in ascending order.

To be compliant with AztecOO, FillComplete() already locally orders ghostnodes such that information received from processor k has a lower local numbering than information received from processor j if k is less than j. SortGhostsAssociatedWithEachProcessor(True) further forces FillComplete() to locally number all ghostnodes received from processor k in ascending order. That is, the local numbering of b is less than c if the global numbering of b is less than c and if both b and c are owned by the same processor. This is done to be compliant with some limited block features within ML. In particular, some ML features require that a block structure of the matrix be maintained even within the ghost variables. Always returns 0.
