Detailed Description

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

Concrete subclasses for MPI-based SPMD distributed-memory Thyra implementations (Note: above graphic is not hyperlinked!)

Concrete MPI-based SPMD Subclasses

The concrete subclasses described here derive directly from the Thyra Operator/Vector Base Support Subclasses for MPI-based SPMD Thyra Implementations.

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

• Thyra::MPIVectorSpaceStd is a general Thyra::VectorSpaceBase subclass implementation for MPI-based SPMD vector spaces which creates Thyra::MPIVectorStd and Thyra::MPIMultiVectorStd objects.

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

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

Together, these concrete subclasses provide a complete and highly efficient implementation for MPI-based 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 MPI SPMD platforms.
