Detailed Description

template<class CountsViewType, class KeysViewType, class SizeType = typename KeysViewType::size_type>
class Tpetra::Details::FHT::CountBuckets< CountsViewType, KeysViewType, SizeType >

Parallel for functor for counting "buckets" in the FixedHashTable.

Template Parameters

CountsViewType	Type of the Kokkos::View specialization used to store the bucket counts; the output of this functor.
KeysViewType	Type of the Kokkos::View specialization used to store the keys; the input of this functor.
SizeType	The parallel loop index type; a built-in integer type. Defaults to the type of the input View's dimension. You may use a shorter type to improve performance.

Tpetra::Details::FHT::CountBuckets< CountsViewType, KeysViewType, SizeType >::CountBuckets ( const counts_view_type &  counts, const keys_view_type &  keys, const size_type  size  )

inline

Constructor.

Parameters

counts	[out] (Preallocated) View of the bucket counts
keys	[in] View of the keys
size	[in] Number of buckets; length of counts

KOKKOS_INLINE_FUNCTION void Tpetra::Details::FHT::CountBuckets< CountsViewType, KeysViewType, SizeType >::operator() ( const size_type &  i ) const

inline

Do this for every entry of keys_.

Count the number of keys in keys_ that hash to the same value.

template<class CountsViewType , class KeysViewType , class SizeType = typename KeysViewType::size_type>

KOKKOS_INLINE_FUNCTION void Tpetra::Details::FHT::CountBuckets< CountsViewType, KeysViewType, SizeType >::operator() ( const size_type &  i, value_type &  dst  ) const

inline

Debug reduce version of above operator().

Set dst to 1 on error (out-of-bounds hash value).
