template<typename T >
void	amrex::SpMV (Long nrows, Long ncols, T *__restrict__ py, CsrView< T const > const &A, T const *__restrict__ px)
	Perform y = A * x using CSR data (GPU/CPU aware).
template<typename T , template< typename > class AllocM, typename AllocV >
void	amrex::SpMV (AlgVector< T, AllocV > &y, SpMatrix< T, AllocM > const &A, AlgVector< T, AllocV > const &x)
	Perform y = A * x using AlgVector wrappers.
template<typename T , template< typename > class AllocM, typename AllocV >
void	amrex::computeResidual (AlgVector< T, AllocV > &res, SpMatrix< T, AllocM > const &A, AlgVector< T, AllocV > const &x, AlgVector< T, AllocV > const &b)
	Compute the residual res = b - A * x.
