Objects of this type can be cast to PreconditionedSolver objects using the __cast methods.

RDF: Documentation goes here.

The regular GMRES solver calls Babel-interface matrix and vector functions. The HGMRES solver calls HYPRE interface functions. The regular solver will work with any consistent matrix, vector, and preconditioner classes. The HGMRES solver will work with the more common combinations.

The HGMRES solver checks whether the matrix, vectors, and preconditioner are of known types, and will not work with any other types. Presently, the recognized data types are: matrix, vector: IJParCSRMatrix, IJParCSRVector preconditioner: BoomerAMG, ParCSRDiagScale
