Kokkos::atomic_resize

Header File: Kokkos_Core.hpp

Usage:

resize(view,n0,n1,n2,n3);
resize(view,layout);

Reallocates a view to have the new dimensions. Can grow or shrink, and will not preserve content.

Synopsis

template <class T, class... P>
void resize(View<T, P...>& v,
        const size_t n0 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n1 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n2 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n3 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n4 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n5 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n6 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n7 = KOKKOS_IMPL_CTOR_DEFAULT_ARG);

template <class T, class... P>
void resize(Kokkos::View<T, P...>& v,
             const typename Kokkos::View<T, P...>::array_layout& layout); 

Description

• template <class T, class... P>
  void resize(View<T, P...>& v,
        const size_t n0 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n1 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n2 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n3 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n4 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n5 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n6 = KOKKOS_IMPL_CTOR_DEFAULT_ARG,
        const size_t n7 = KOKKOS_IMPL_CTOR_DEFAULT_ARG);

  Resizes v to have the new dimensions while preserving the contents for the common subview of the old and new view.

  • v: existing view, can be a default constructed one.
  • n[X]: new length for extent X.

  Restrictions:

  • View<T, P...>::array_layout is either LayoutLeft or LayoutRight.

• template <class T, class... P>
  void resize(Kokkos::View<T, P...>& v,
             const typename Kokkos::View<T, P...>::array_layout& layout); 

  Resizes v to have the new dimensions while preserving the contents for the common subview of the old and new view.

  • v: existing view, can be a default constructed one.
  • layout: a layout instance containing the new dimensions.
