rotate_copy¶
Header: Kokkos_StdAlgorithms.hpp
Copies the elements from the range [first_from, last_from) to the range starting at first_to or from view_from to view_dest in such a way that the element n_first or view(n_location) becomes the first element of the new range and n_first - 1 becomes the last element.
Warning
This is currently inside the Kokkos::Experimental namespace.

Overload set accepting a team handle¶
Added in version 4.2.
template <class TeamHandleType, class InputIterator, class OutputIterator>
KOKKOS_FUNCTION
OutputIterator rotate_copy(const TeamHandleType& teamHandle, (5)
InputIterator first_from,
InputIterator n_first,
InputIterator last_from,
OutputIterator first_to);
template <
class TeamHandleType,
class DataType1, class... Properties1,
class DataType2, class... Properties2>
KOKKOS_FUNCTION
auto rotate_copy(const TeamHandleType& teamHandle, (6)
const Kokkos::View<DataType1, Properties1...>& source,
std::size_t n_location,
const Kokkos::View<DataType2, Properties2...>& dest);
Parameters and Requirements¶
exespace: execution space instance
teamHandle: team handle instance given inside a parallel region when using a TeamPolicy
label: string forwarded to internal parallel kernels for debugging purposes
1: The default string is “Kokkos::rotate_copy_iterator_api_default”.
3: The default string is “Kokkos::rotate_copy_view_api_default”.
NOTE: overloads accepting a team handle do not use a label internally
first_from, last_from: range of elements to copy from
must be random access iterators, e.g., returned from Kokkos::Experimental::(c)begin/(c)end
must represent a valid range, i.e., last >= first
must be accessible from exespace or from the execution space associated with the team handle
first_to: beginning of the range to copy to
must be random access iterators, e.g., returned from Kokkos::Experimental::(c)begin/(c)end
must be accessible from exespace or from the execution space associated with the team handle
n_first: iterator to element that should be the first of the rotated range
must be random access iterators, e.g., returned from Kokkos::Experimental::(c)begin/(c)end
must be such that [first_from, n_first) and [n_first, last_from) are valid ranges.
must be accessible from exespace or from the execution space associated with the team handle
source, dest:
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
n_location: integer value identifying the element to rotate about
Iterator to the element after the last element copied.
