Detailed Description

Epetra_VbrMatrix: A class for the construction and use of real-valued double-precision variable block-row sparse matrices.

The Epetra_VbrMatrix class is a sparse variable block 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_VbrMatrix are matrix times vector and matrix times multi-vector multiplication.

Creating and filling Epetra_VbrMatrix objects

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

Create Epetra_VbrMatrix instance 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.
Input coefficient values (more detail on this below).
Complete construction by calling FillComplete.

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

Using Epetra_VbrMatrix as an Epetra_RowMatrix

Although Epetra_VbrMatrix does inherit from Epetra_RowMatrix, a design flaw in the inheritance structure of Epetra prohibits the use of an Epetra_VbrMatrix object as an Epetra_RowMatrix in some important situations. Therefore we recommend the use of the Epetra_VbrRowMatrix class to wrap an Epetra_VbrMatrix object for use as an Epetra_RowMatrix. The Epetra_VbrRowMatrix object does not duplicate data in the Epetra_VbrMatrix object, but uses it to satisfy the Epetra_RowMatrix interface.

Epetra_Map attributes

Epetra_VbrMatrix 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_VbrMatrix 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_VbrMatrix::FillComplete() is called.) The state of the indices in the graph determines the behavior of many Epetra_VbrMatrix methods. If an Epetra_VbrMatrix 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_VbrMatrix::FillComplete() is called. The query function Epetra_VbrMatrix::Filled() returns true if Epetra_VbrMatrix::FillComplete() has been called.

Inputting coefficient values

The process for inputting block-entry coefficients is as follows:

Indicate that values for a specified row are about to be provided by calling one of these methods which specify a block-row and a list of block-column-indices:
Loop over the list of block-column-indices and pass each block-entry to the matrix using the method SubmitBlockEntry().
Complete the process for the specified block-row by calling the method EndSubmitEntries().

Note that the 'GlobalValues' methods have the precondition that IndicesAreGlobal() must be true, and the 'MyValues' methods have the precondition that IndicesAreLocal() must be true. Furthermore, the 'SumInto' and 'Replace' methods may only be used to update matrix entries which already exist, and the 'Insert' methods may only be used if IndicesAreContiguous() is false.

Counting Floating Point Operations

Each Epetra_VbrMatrix 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.

int Epetra_VbrMatrix::SetUseTranspose ( bool UseTranspose_in )

inlinevirtual

If set true, transpose of this operator will be applied.

  This flag allows the transpose of the given operator to be used implicitly.  Setting this flag
  affects only the Apply() and ApplyInverse() methods.  If the implementation of this interface

does not support transpose use, this method should return a value of -1.

Parameters

In	UseTranspose -If true, multiply by the transpose of operator, otherwise just use operator.

Returns: Always returns 0.

Implements Epetra_Operator.

int Epetra_VbrMatrix::Apply	(	const Epetra_MultiVector &	X,
		Epetra_MultiVector &	Y
	)		const

virtual

Returns the result of a Epetra_Operator applied to a Epetra_MultiVector X in Y.

Parameters

In	X - A Epetra_MultiVector of dimension NumVectors to multiply with matrix.
Out	Y -A Epetra_MultiVector of dimension NumVectors containing result.

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

Implements Epetra_Operator.

int Epetra_VbrMatrix::ApplyInverse	(	const Epetra_MultiVector &	X,
		Epetra_MultiVector &	Y
	)		const

virtual

Returns the result of a Epetra_Operator inverse applied to an Epetra_MultiVector X in Y.

  In this implementation, we use several existing attributes to determine how virtual
  method ApplyInverse() should call the concrete method Solve().  We pass in the UpperTriangular(),

the Epetra_VbrMatrix::UseTranspose(), and NoDiagonal() methods. The most notable warning is that if a matrix has no diagonal values we assume that there is an implicit unit diagonal that should be accounted for when doing a triangular solve.

Parameters

In	X - A Epetra_MultiVector of dimension NumVectors to solve for.
Out	Y -A Epetra_MultiVector of dimension NumVectors containing result.

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

Implements Epetra_Operator.
