Detailed Description

template<class Scalar, class LocalOrdinal = int, class GlobalOrdinal = LocalOrdinal, class Node = Kokkos::DefaultNode::DefaultNodeType, class LocalMatOps = typename Kokkos::DefaultKernels<Scalar,LocalOrdinal,Node>::BlockSparseOps>
class Tpetra::VbrMatrix< Scalar, LocalOrdinal, GlobalOrdinal, Node, LocalMatOps >

VbrMatrix: Variable block row matrix.

The VbrMatrix class has two significant 'states', distinguished by whether or not storage has been optimized (packed) or not.

When the matrix is in the non-optimized-storage state, internal data storage is in a non-contiguous data-structure that allows for convenient insertion of data.

When the matrix is in the optimized-storage state, internal data is stored in contiguous (packed) arrays. When in this state, existing entries may be updated and replaced, but no new entries (indices and/or coefficients) may be inserted. In other words, the sparsity pattern or structure of the matrix may not be changed.

Use of the matrix as an Operator (performing matrix-vector multiplication) is only allowed when it is in the optimized-storage state.

VbrMatrix has two constructors, one which leaves the matrix in the optimized- storage state, and another which leaves the matrix in the non-optimized-storage state.

When the VbrMatrix is constructed in the non-optimized-storage state, (and then filled using methods such as setGlobalBlockEntry etc.), it can then be transformed to the optimized-storage state by calling the method fillComplete().

Once in the optimized-storage state, the VbrMatrix can not be returned to the non-optimized-storage state.

Constructor & Destructor Documentation

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node , class LocalMatOps >
Tpetra::VbrMatrix< Scalar, LocalOrdinal, GlobalOrdinal, Node, LocalMatOps >::VbrMatrix ( const Teuchos::RCP< const BlockMap< LocalOrdinal, GlobalOrdinal, Node > > &  blkRowMap,
size_t  maxNumEntriesPerRow,
ProfileType  pftype = DynamicProfile 
)

Constructor specifying the row-map and the max number of (block) non-zeros for all rows.

After this constructor completes, the VbrMatrix is in the non-packed, non-optimized-storage, isFillComplete()==false state. Block-entries (rectangular, dense submatrices) may be inserted using class methods such as setGlobalBlockEntry(...), declared below.

Definition at line 71 of file Tpetra_VbrMatrix_def.hpp.

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node , class LocalMatOps >
Tpetra::VbrMatrix< Scalar, LocalOrdinal, GlobalOrdinal, Node, LocalMatOps >::VbrMatrix ( const Teuchos::RCP< const BlockCrsGraph< LocalOrdinal, GlobalOrdinal, Node > > &  blkGraph)

Constructor specifying a pre-filled block-graph.

Constructing a VbrMatrix with a pre-filled graph means that the matrix will start out in the optimized-storage state, i.e., isFillComplete()==true. The graph provided to this constructor must be already filled. (If blkGraph->isFillComplete() == false, an exception is thrown.)

Entries in the input BlockCrsGraph correspond to block-entries in the VbrMatrix. In other words, the VbrMatrix will have a block-row corresponding to each row in the graph, and a block-entry corresponding to each column- index in the graph.

Multiply this matrix by a MultiVector.

X is required to be post-imported, i.e., described by the column map of the matrix. Y is required to be pre-exported, i.e., described by the row map of the matrix. See also the Operator::apply method which is implemented below.

MultiVector< DomainScalar, LocalOrdinal, GlobalOrdinal, Node > &  X,
Teuchos::ETransp  trans 
) const

Triangular Solve -- Matrix must be triangular.

Find X such that A*X = Y. X is required to be post-imported, i.e., described by the column map of the matrix. Y is required to be pre-exported, i.e., described by the row map of the matrix.

Both X and Y are required to have constant stride.

Note that if the diagonal block-entries are stored, they must be triangular. I.e., the matrix structure must be block-triangular, and any diagonal blocks must be "point"-triangular, meaning that coefficients on the "wrong" side of the point-diagonal must be zero.

Teuchos::ETransp  trans = Teuchos::NO_TRANS,
Scalar  alpha = Teuchos::ScalarTraits<Scalar>::one(),
Scalar  beta = Teuchos::ScalarTraits<Scalar>::zero() 
) const [virtual]

Computes the operator-multivector application.

Loosely, performs $Y = \alpha \cdot A^{\textrm{trans}} \cdot X + \beta \cdot Y$. However, the details of operation vary according to the values of alpha and beta. Specifically

  • if beta == 0, apply() must overwrite Y, so that any values in Y (including NaNs) are ignored.
  • if alpha == 0, apply() may short-circuit the operator, so that any values in X (including NaNs) are ignored.

Copy the contents of the input block-entry into the matrix.

Copy the contents of the input block-entry into the matrix.

This method will throw an exception if fillComplete() has not yet been called, or if the specified block-entry doesn't already exist in the matrix.

The coefficients for the specified block-entry will be over-written (replaced) by the input block-entry.

LocalOrdinal  blkRowSize,

const Teuchos::ArrayView< const Scalar > &  blockEntry 
)

Add the contents of the input block-entry into the matrix.

This method will create the specified block-entry if it doesn't already exist, but only if fillComplete() has not yet been called.

If the specified block-entry already exists in the matrix, the contents of the input block-entry will be added to the values that are already present.

Note that if globalBlockRow is not owned by the local processor (as indicated by getBlockRowMap()) then the block-entry is held in temporary storage until globalAssemble() is called (which is called internally by fillComplete()) and then globalAssemble() performans the communication needed to move the data to the owning processor.

This method may be called any time (before or after fillComplete()).

Returns a const read-only view of a block-entry.

Returns a non-const read-write view of a block-entry.

Creates the block-entry if it doesn't already exist, and if:

  • the arguments numPtRows and numPtCols are set on entry (and nonzero),
  • and if fillComplete() has not yet been called.

Important Note: Be very careful managing the lifetime of this view. If fillComplete() has been called, and if you are running on a GPU, this view may be a copy of memory from the GPU, and your changes to the view won't be copied back to the GPU until your ArrayRCP is destroyed or set to Teuchos::null.

Perform copies and permutations that are local to this image.

Parameters:
source[in] On entry, the DistObject that we are importing from.
numSameIDs[in] On entry, the number of elements that are the same on the source and dest objects. (i.e. The element is owned by the same image in both source and dest, and no permutation occurs.)
numPermuteIDs[in] On entry, the number of elements that are locally permuted between source and dest objects.
permuteToLIDs[in] On entry, contains a list of the elements that are permuted. (Listed by their LID in the destination DistObject.)
permuteFromLIDs[in] On entry, contains a list of the elements that are permuted. (Listed by their LID in the source DistObject.)

numPacketsPerLID[out] On exit, numPacketsPerLID[i] contains the number of packets to be exported for exportLIDs[i].
constantNumPackets[out] On exit, 0 if numPacketsPerLID has variable contents (different size for each LID). If nonzero, then it is expected that num-packets-per-LID is constant, and constantNumPackets holds that value.
