allow_rebuild

template<class Backend, class Coarsening, class Relaxation, class DirectSolver = DistributedSkylineLUDirectSolver<typename Backend::value_type>, class Repartition = SimpleMatrixPartitioner<Backend>>

bool Arcane::Alina::DistributedAMG< Backend, Coarsening, Relaxation, DirectSolver, Repartition >::params::allow_rebuild = false

Keep matrices in internal format to allow for quick rebuild of the hierarchy.

coarse_enough

template<class Backend, class Coarsening, class Relaxation, class DirectSolver = DistributedSkylineLUDirectSolver<typename Backend::value_type>, class Repartition = SimpleMatrixPartitioner<Backend>>

Int32 Arcane::Alina::DistributedAMG< Backend, Coarsening, Relaxation, DirectSolver, Repartition >::params::coarse_enough = DirectSolver::coarse_enough()

Specifies when level is coarse enough to be solved directly.

If number of variables at a next level in the hierarchy becomes lower than this threshold, then the hierarchy construction is stopped and the linear system is solved directly at this level.

coarsening

template<class Backend, class Coarsening, class Relaxation, class DirectSolver = DistributedSkylineLUDirectSolver<typename Backend::value_type>, class Repartition = SimpleMatrixPartitioner<Backend>>

coarsening_params Arcane::Alina::DistributedAMG< Backend, Coarsening, Relaxation, DirectSolver, Repartition >::params::coarsening

Coarsening parameters.

direct

template<class Backend, class Coarsening, class Relaxation, class DirectSolver = DistributedSkylineLUDirectSolver<typename Backend::value_type>, class Repartition = SimpleMatrixPartitioner<Backend>>

direct_params Arcane::Alina::DistributedAMG< Backend, Coarsening, Relaxation, DirectSolver, Repartition >::params::direct

Direct solver parameters.

Définition à la ligne 73 du fichier DistributedAMG.h.

direct_coarse

template<class Backend, class Coarsening, class Relaxation, class DirectSolver = DistributedSkylineLUDirectSolver<typename Backend::value_type>, class Repartition = SimpleMatrixPartitioner<Backend>>

bool Arcane::Alina::DistributedAMG< Backend, Coarsening, Relaxation, DirectSolver, Repartition >::params::direct_coarse = true

Use direct solver at the coarsest level.

When set, the coarsest level is solved with a direct solver. Otherwise a smoother is used as a solver.

max_levels

template<class Backend, class Coarsening, class Relaxation, class DirectSolver = DistributedSkylineLUDirectSolver<typename Backend::value_type>, class Repartition = SimpleMatrixPartitioner<Backend>>

Int32 Arcane::Alina::DistributedAMG< Backend, Coarsening, Relaxation, DirectSolver, Repartition >::params::max_levels = std::numeric_limits<Int32>::max()

Maximum number of levels.

If this number is reached while the size of the last level is greater that coarse_enough, then the coarsest level will not be solved exactly, but will use a smoother.
