m_ordering Module

"Application storage" stores spatial data with a directionality for better cache locality This set of functions converts indices from this application storage (_dir) to cartesian indices (_ijk)


Uses


Interfaces

public interface get_index_reordering

  • public pure subroutine get_index_reordering_rdr(out_i, out_j, out_k, in_i, in_j, in_k, reorder_dir, mesh)

    Arguments

    Type IntentOptional Attributes Name
    integer, intent(out) :: out_i
    integer, intent(out) :: out_j
    integer, intent(out) :: out_k
    integer, intent(in) :: in_i
    integer, intent(in) :: in_j
    integer, intent(in) :: in_k
    integer, intent(in) :: reorder_dir
    class(mesh_t), intent(in) :: mesh

  • public pure subroutine get_index_reordering_dirs(out_i, out_j, out_k, in_i, in_j, in_k, dir_from, dir_to, mesh)

    Converts a set of application storage directional index to an other direction. The two directions are defined by the reorder_dir variable, RDR_X2Y will go from storage in X to Y etc.

    Arguments

    Type IntentOptional Attributes Name

    integer, intent(in) :: in_j
    integer, intent(in) :: in_k
    integer, intent(in) :: dir_from
    integer, intent(in) :: dir_to
