Detailed Description

The package Thyra contains highly efficient concrete implementations of SPMD vector space, vector and multi-vector subclasses.

Concrete SPMD Subclasses

The concrete subclasses described here, for the most part, derive directly from the Thyra Operator/Vector Base Support Subclasses for SPMD Thyra Implementations.

• Thyra::DefaultSpmdVectorSpaceFactory is a concrete Thyra::VectorSpaceFactoryBase subclass implementation that creates locally replicated Thyra::DefaultSpmdVectorSpace objects given their dimension. This class is meant to create domain spaces for any SPMD multi-vector object it is is used as such (for example, see Thyra::SpmdVectorSpaceDefaultBase::smallVecSpcFcty()).

• Thyra::DefaultSpmdVectorSpace is a general Thyra::VectorSpaceBase subclass implementation for SPMD vector spaces which creates Thyra::DefaultSpmdVector and Thyra::DefaultSpmdMultiVector objects.

• Thyra::DefaultSpmdVector is a very general, highly efficient Thyra::VectorBase subclass implementation for SPMD vectors. Objects of this type can be constructed from a variety of data sources due to the magic of Teuchos::RCP.

• Thyra::DefaultSpmdMultiVector is a very general, highly efficient Thyra::MultiVectorBase subclass implementation for SPMD multi-vectors. Objects of this type can be constructed from a variety of data sources due to the magic of Teuchos::RCP.

• Thyra::DefaultSpmdMultiVectorFileIO in a concrete implementation of Thyra::MultiVectorFileIO that reads and writes (multi)vector to and from files in parallel. Each process is given its own file name and has its own extension.

Together, these concrete subclasses provide a complete and highly efficient implementation for SPMD vector, multi-vector and vector space objects. From the standpoint of the needs of an ANA, there is really no need for any other concrete implementations of these subclasses for SPMD platforms.
