Detailed Description

template<typename ValueType = double, typename IndexType = int32_t>
class GinkgoWrappers::SolverIR< ValueType, IndexType >

An implementation of the solver interface using the Ginkgo IR solver.

Iterative refinement (IR) is an iterative method that uses another coarse method to approximate the error of the current solution via the current residual.

Constructor & Destructor Documentation

◆ SolverIR() [1/2]

template<typename ValueType , typename IndexType >

GinkgoWrappers::SolverIR< ValueType, IndexType >::SolverIR	(	SolverControl &	solver_control,
		const std::string &	exec_type,
		const AdditionalData &	data = `AdditionalData()`
	)

Constructor.

Parameters

[in,out]	solver_control	The solver control object is then used to set the parameters and setup the IR solver from the IR factory which solves the linear system.
[in]	exec_type	The execution paradigm for the IR solver.
[in]	data	The additional data required by the solver.
