Detailed Description

template<typename Number>
class CUDAWrappers::SolverDirect< Number >

Direct solvers. These solvers call cuSOLVER underneath.

Note
Instantiations for this template are provided for <float> and <double>.

Constructor & Destructor Documentation

◆ SolverDirect()

template<typename Number >
CUDAWrappers::SolverDirect< Number >::SolverDirect ( const Utilities::CUDA::Handle handle,
SolverControl cn,
const AdditionalData data = AdditionalData() 
)

Constructor. Takes the solver control object and creates the solver.

◆ ~SolverDirect()

template<typename Number >
virtual CUDAWrappers::SolverDirect< Number >::~SolverDirect ( )
virtualdefault

Destructor.

Member Function Documentation

◆ solve()

template<typename Number >
void CUDAWrappers::SolverDirect< Number >::solve ( const SparseMatrix< Number > &  A,
LinearAlgebra::CUDAWrappers::Vector< Number > &  x,
const LinearAlgebra::CUDAWrappers::Vector< Number > &  b 
)

Solve the linear system Ax=b.

◆ control()

template<typename Number >
SolverControl& CUDAWrappers::SolverDirect< Number >::control ( ) const

Access to object that controls convergence.

Member Data Documentation

◆ cuda_handle

template<typename Number >
const Utilities::CUDA::Handle& CUDAWrappers::SolverDirect< Number >::cuda_handle
private

Handle

Definition at line 99 of file cuda_solver_direct.h.

◆ solver_control

template<typename Number >
SolverControl& CUDAWrappers::SolverDirect< Number >::solver_control
private

Reference to the object that controls convergence of the iterative solver. In fact, for these CUDA wrappers, cuSOLVER and cuSPARSE do so themselves, but we copy the data from this object before starting the solution process, and copy the data back into it afterwards.

Definition at line 107 of file cuda_solver_direct.h.

◆ additional_data

template<typename Number >
const AdditionalData CUDAWrappers::SolverDirect< Number >::additional_data
private

Store a copy of the flags for this particular solver.
