Detailed Description

template<class Operator, template< class > class UnderlyingSolver, class X>
class Opm::gpuistl::SolverAdapter< Operator, UnderlyingSolver, X >

Wraps a CUDA solver to work with CPU data.

Template Parameters

Operator	the Dune::LinearOperator to use
UnderlyingSolver	a Dune solver like class, eg Dune::BiCGSTABSolver
X	the outer type to use (eg. Dune::BlockVector<Dune::FieldVector<...>>)

Parameters

op	the linear operator (assumed CPU, the output (matrix) of which will be converted to a GPU variant)
sp	the scalar product (assumed CPU, this will be converted to a GPU variant)
reduction	the reduction factor passed to the iterative solver
maxit	maximum number of iterations for the linear solver
verbose	verbosity level
comm	the communication object. If this is Dune::Amg::SequentialInformation, we assume a serial setup
