parameters_type &	with_loggers (Args &&... _value)
	Provides the loggers to be added to the factory and its generated objects in a fluent interface.
std::unique_ptr< Factory >	on (std::shared_ptr< const Executor > exec) const
	Creates a new factory on the specified executor.

Public Attributes
gko::size_type	num_rhs {1u}
	Number of right hand sides.
bool	unit_diagonal {false}
	Should the solver use the values on the diagonal of the system matrix (false) or should it assume they are 1.0 (true)?
trisolve_algorithm	algorithm {trisolve_algorithm::sparselib}
	Select the implementation which is supposed to be used for the triangular solver.

Member Data Documentation

algorithm

template<typename ValueType = default_precision, typename IndexType = int32>

trisolve_algorithm gko::solver::LowerTrs< ValueType, IndexType >::parameters_type::algorithm {trisolve_algorithm::sparselib}

Select the implementation which is supposed to be used for the triangular solver.

This only matters for the Cuda executor where the choice is between the Ginkgo (syncfree) and the cuSPARSE (sparselib) implementation. Default is sparselib.

num_rhs

template<typename ValueType = default_precision, typename IndexType = int32>

gko::size_type gko::solver::LowerTrs< ValueType, IndexType >::parameters_type::num_rhs {1u}

Number of right hand sides.

Note

This value is currently only required for the CUDA trisolve_algorithm::sparselib algorithm.
