SolverParameters_t Derived Type

type, public :: SolverParameters_t

A class for passing parameters to an iterative solver.


Contents


Components

TypeVisibility AttributesNameInitial
real(kind=NTREAL), public :: converge_diff

When do we consider a calculation converged.

integer, public :: max_iterations

Maximum number of iterations of a solver before termination.

real(kind=NTREAL), public :: threshold

Threshold for sparse multiplication and addition.

logical, public :: be_verbose

If true, the sparse solver prints out information each loop iteration.

logical, public :: do_load_balancing

If true, the sparse solver will try and load balance before calculation.

type(Permutation_t), public :: BalancePermutation

The permutation used for load balancing.


Constructor

public interface SolverParameters_t

  • private pure function SolverParameters_init(converge_diff_in, threshold_in, max_iterations_in, be_verbose_in, BalancePermutation_in) result(this)

    Construct a data type which stores iterative solver parameters.

    Arguments

    Type IntentOptional AttributesName
    real(kind=NTREAL), intent(in), optional :: converge_diff_in

    Converge_diff_in the difference between iterations to consider a calculation converged.

    real(kind=NTREAL), intent(in), optional :: threshold_in

    The zero threshold

    integer, intent(in), optional :: max_iterations_in

    The maximum number of iterations to perform

    logical, intent(in), optional :: be_verbose_in

    Whether to print during the calculation (default = False)

    type(Permutation_t), intent(in), optional :: BalancePermutation_in

    For load balancing

    Return Value type(SolverParameters_t)
