Detailed Description

template<class Scalar, class LocalOrdinal = typename Xpetra::Matrix<double>::local_ordinal_type, class GlobalOrdinal = typename Xpetra::Matrix<double, LocalOrdinal>::global_ordinal_type, class Node = typename Xpetra::Matrix<double, LocalOrdinal, GlobalOrdinal>::node_type>
class MueLu::ZoltanInterface< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Interface to Zoltan library.

This interface provides access to partitioning methods in Zoltan. Currently, it supports the RCB algorithm only.

Member Function Documentation

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
RCP< const ParameterList > MueLu::ZoltanInterface< Scalar, LocalOrdinal, GlobalOrdinal, Node >::GetValidParameterList ( ) const
virtual

Return a const parameter list of valid parameters that setParameterList() will accept.

Also define the default values of parameters according to the input parameter list.

Reimplemented from MueLu::Factory.

Definition at line 64 of file MueLu_ZoltanInterface_def.hpp.

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
void MueLu::ZoltanInterface< Scalar, LocalOrdinal, GlobalOrdinal, Node >::DeclareInput ( Level currentLevel) const
virtual

Specifies the data that this class needs, and the factories that generate that data.

If the Build method of this class requires some data, but the generating factory is not specified in DeclareInput, then this class will fall back to the settings in FactoryManager.

Implements MueLu::SingleLevelFactoryBase.

Definition at line 75 of file MueLu_ZoltanInterface_def.hpp.

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
void MueLu::ZoltanInterface< Scalar, LocalOrdinal, GlobalOrdinal, Node >::Build ( Level currentLevel) const
virtual

Build an object with this factory.

Implements MueLu::SingleLevelFactoryBase.

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
int MueLu::ZoltanInterface< Scalar, LocalOrdinal, GlobalOrdinal, Node >::GetLocalNumberOfRows ( void *  data,
int *  ierr 
)
static

Callback function that returns the local number of objects. Required by Zoltan.

In this case, the number of objects is the number of local rows.

Parameters
data(in) void pointer to an Xpetra::Matrix.
ierr(out) error code.

Definition at line 189 of file MueLu_ZoltanInterface_def.hpp.

int  NumLidEntries,
ZOLTAN_ID_PTR  gids,
ZOLTAN_ID_PTR  lids,
int  wgtDim,
float *  weights,
int *  ierr 
)
static

Callback function that returns the local number of nonzeros in the matrix. Required by Zoltan.

FIXME: Note that this will not work properly for non-point matrices.

Parameters
data(in) void pointer to an Xpetra::Matrix
weights(out) array whose ith entry is the number of nonzeros in local row i.
ierr(out) error code

static

Callback function that returns the problem dimension. Required by Zoltan.

Parameters
data(in) void pointer to integer dimension
ierr(out) error code

static

Callback function that returns the problem dimension. Required by Zoltan.

Parameters
data(in) void pointer to Xpetra::MultiVector.
coordinates(out) array of double coordinates, arranged like so: [x1 y1 z1 x2 y2 z2 ...].
ierr(out) error code

TODO – should I return a view of the coordinates instead of copying them?
