Detailed Description

template<class LO, class S, class NodeTsqrType, class DistTsqrType>
class TSQR::Trilinos::TsqrFactory< LO, S, NodeTsqrType, DistTsqrType >

Base class for TSQR implementation instantiation.

Each child class of TsqrFactory know how to instantiate a particular TSQR implementation. TsqrFactory contains all common functionality for this task.

Note:

Unless you need to change the interface between Trilinos and TSQR, you don't need to do anything with TsqrFactory or its subclasses. Just choose the appropriate subclass of TsqrAdaptor. TsqrFactory and its subclasses don't have anything to do with any of the Trilinos multivector classes.

If you have implemented a new intranode TSQR factorization type, you'll need to create a subclass of TsqrFactory that knows how to instantiate that intranode TSQR class.

If you have implemented a new internode TSQR factorization type, you'll need to create a subclass of TsqrFactory that knows how to instantiate that internode TSQR class.

If you want to change which TSQR implementation is invoked for a particular multivector (MV) class, you don't need to do anything with this class, as long as the appropriate subclass of TsqrFactory for the desired NodeTsqrType and DistTsqrType exists. Just change the factory_type typedef in the specialization of TsqrTypeAdaptor for the MV class.

Member Function Documentation

template<class LO, class S, class NodeTsqrType, class DistTsqrType>

virtual void TSQR::Trilinos::TsqrFactory< LO, S, NodeTsqrType, DistTsqrType >::makeTsqr	(	const Teuchos::ParameterList &	plist,
		const scalar_messenger_ptr &	messenger,
		tsqr_ptr &	tsqr
	)		const [inline, virtual]

Instantiate and return TSQR implementation.

Instantiate and return (through the output arguments) the two TSQR implementation objects.

Parameters:

plist	[in] Parameter list (keys depend on the subclass; keys are accessed in the subclass' makeNodeTsqr() method)
scalar_messenger_ptr	[in] Pointer to the underlying internode communication handler, as initialized by TSQR::Trilinos::CommFactory.
node_tsqr	[out] On output, points to the node_tsqr_type object that TSQR will use for the intranode part of its computations.
tsqr	[out] On output, points to the node_tsqr_type object that TSQR will use for the internode part of its computations.
