class MueLu::TekoSmoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Interface to block smoothers in Teko package.

This is a dummy implementation for arbitrary scalars (different than SC=double). We use Teko and the Teko::LinearOp which is declared as Teuchos::RCP<const Thyra::LinearOpBase<ST> > with ST=double. See e.g. Teko_ConfigDefs.hpp.

This is the specialization for SC=double and LO=int, which actually implements the Teko smoother interface. We use Teko and the Teko::LinearOp which is declared as Teuchos::RCP<const Thyra::LinearOpBase<ST> > with ST=double. See e.g. Teko_ConfigDefs.hpp.

In Teko SC=double and LO=int are hard-coded. The node is Tpetra::Map<>::node_type. The global ordinal GO is chosen as a conservative choice from what Tpetra supports (see Teko_ConfigDefs.hpp for more details)

Note, that the underlying Thyra package is only templated on the Scalar (not the node type).
