`realloc`#

Header File: <Kokkos_Core.hpp>

Usage#

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

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

Description#

template <class T, class... P>
void realloc(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 without preserving its contents.
- 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 I, class T, class... P>
void realloc(const I& arg_prop, Kokkos::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 without preserving its contents. The new Kokkos::View is constructed using the View constructor property arg_prop, e.g., Kokkos::WithoutInitializing.
- v: existing view, can be a default constructed one.
- n[X]: new length for extent X.
- arg_prop: View constructor property, e.g., Kokkos::WithoutInitializing.
Restrictions: View<T, P...>::array_layout is either LayoutLeft or LayoutRight.

template <class... ViewCtorArgs, class T, class... P>
void realloc(const Impl::ViewCtorProp<ViewCtorArgs...>& arg_prop,
             Kokkos::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 without preserving its contents. The new Kokkos::View is constructed using the View constructor properties arg_prop, e.g., Kokkos::view_alloc(Kokkos::WithoutInitializing).
- v: existing view, can be a default constructed one.
- n[X]: new length for extent X.
- arg_prop: View constructor properties, e.g., Kokkos::view_alloc(Kokkos::WithoutInitializing).
Restrictions:
- View<T, P...>::array_layout is either LayoutLeft or LayoutRight.
- arg_prop must not include a pointer to memory, a label, or a memory space.

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

Resizes v to have the new dimensions without preserving its contents.
- v: existing view, can be a default constructed one.
- layout: a layout instance containing the new dimensions.

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

Resizes v to have the new dimensions without preserving its contents. The new Kokkos::View is constructed using the View constructor property arg_prop, e.g., Kokkos::WithoutInitializing.
- v: existing view, can be a default constructed one.
- layout: a layout instance containing the new dimensions.
- arg_prop: View constructor property, e.g., Kokkos::WithoutInitializing.

template <class... ViewCtorArgs, class T, class... P>
void realloc(const Impl::ViewCtorProp<ViewCtorArgs...>& arg_prop,
             Kokkos::View<T, P...>& v,
             const typename Kokkos::View<T, P...>::array_layout& layout);

Resizes v to have the new dimensions without preserving its contents. The new Kokkos::View is constructed using the View constructor properties arg_prop, e.g., Kokkos::view_alloc(Kokkos::WithoutInitializing).
- v: existing view, can be a default constructed one.
- layout: a layout instance containing the new dimensions.
- arg_prop: View constructor properties, e.g., Kokkos::view_alloc(Kokkos::WithoutInitializing).
Restrictions: arg_prop must not include a pointer to memory, a label, or a memory space.

Example#

Kokkos::realloc(v, 2, 3);

Reallocate a Kokkos::View with dynamic rank 2 to have dynamic extent 2 and 3 respectively.

Kokkos::realloc(Kokkos::WithoutInitializing, v, 2, 3);

Reallocate a Kokkos::View with dynamic rank 2 to have dynamic extent 2 and 3 respectively. After this call, the View is uninitialized.
