Detailed Description

template<class Scalar, class LocalOrdinal, class GlobalOrdinal, class Node>
class MueLu::AMGXOperator< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Adapter for AmgX library from Nvidia.

This templated version of the class throws errors in all methods as AmgX is not implemented for datatypes where scalar!=double/float and ordinal !=int

Creates an AmgX Solver object with a Tpetra Matrix. Partial specialization of the template for data types supported by AmgX.
