Type-Bound Procedures

procedure, public :: define_partitions

  • interface

    Gathers are inherently expensive and are best used either 1. Near the beginning/end of execution to amortize costs across an entire run or 2. Temporarily while developing/debugging code.

    private pure module subroutine define_partitions(self, cardinality)

    define the range of data identification numbers owned by the executing image

    Arguments

    Type IntentOptional Attributes Name
    class(data_partition_t), intent(inout) :: self
    integer, intent(in) :: cardinality

procedure, public :: first

  • interface

    Gathers are inherently expensive and are best used either 1. Near the beginning/end of execution to amortize costs across an entire run or 2. Temporarily while developing/debugging code.

    private pure module function first(self, image_number) result(first_index)

    the result is the first identification number owned by the executing image

    Arguments

    Type IntentOptional Attributes Name
    class(data_partition_t), intent(in) :: self
    integer, intent(in), optional :: image_number

    Return Value integer
