generate - Kokkos documentation

Header: <Kokkos_StdAlgorithms.hpp>

Assigns the value generated by the functor g to each elements in the range [first, last) (overloads 1,2,5) or in the view (overloads 3,4,6).

Warning

This is currently inside the Kokkos::Experimental namespace.

template <class ExecutionSpace, class IteratorType, class GeneratorType>
void generate(const ExecutionSpace& exespace,                                (1)
              IteratorType first, IteratorType last,
              GeneratorType g);

template <class ExecutionSpace, class IteratorType, class GeneratorType>
void generate(const std::string& label, const ExecutionSpace& exespace,      (2)
              IteratorType first, IteratorType last,
              GeneratorType g);

template <class ExecutionSpace, class DataType, class... Properties, class GeneratorType>
void generate(const ExecutionSpace& exespace,                                (3)
              const Kokkos::View<DataType, Properties...>& view,
              GeneratorType g);

template <class ExecutionSpace, class DataType, class... Properties, class GeneratorType>
void generate(const std::string& label, const ExecutionSpace& exespace,      (4)
              const Kokkos::View<DataType, Properties...>& view,
              GeneratorType g);

Added in version 4.2.

template <class TeamHandleType, class IteratorType, class GeneratorType>
KOKKOS_FUNCTION
void generate(const TeamHandleType& teamHandle,                              (5)
              IteratorType first, IteratorType last,
              GeneratorType g);

template <class TeamHandleType, class DataType, class... Properties, class GeneratorType>
KOKKOS_FUNCTION
void generate(const TeamHandleType& teamHandle,                              (6)
              const Kokkos::View<DataType, Properties...>& view,
              GeneratorType g);

• exespace: execution space instance

• teamHandle: team handle instance given inside a parallel region when using a TeamPolicy

• label: used to name the implementation kernels for debugging purposes

  • for 1, the default string is: “Kokkos::generate_iterator_api_default”

  • for 3, the default string is: “Kokkos::generate_view_api_default”

  • NOTE: overloads accepting a team handle do not use a label internally

• first, last: range of elements to modify

  • must be random access iterators

  • must represent a valid range, i.e., last >= first (checked in debug mode)

  • must be accessible from exespace or from the execution space associated with the team handle

• view: view to modify

  • must be rank-1, and have LayoutLeft, LayoutRight, or LayoutStride

  • must be accessible from exespace or from the execution space associated with the team handle

• g:

  • functor of the following form, where return_type must be assignable to value_type, with value_type being the value type of IteratorType or of view:

  struct Generate
  {
      KOKKOS_INLINE_FUNCTION
      return_type operator()() const{ return /* ... */; }
  };
