AccumT cub::internal::ThreadReduce(T *input, ReductionOp reduction_op, PrefixT prefix)

Perform a sequential reduction over LENGTH elements of the input array, seeded with the specified prefix.

The aggregate is returned.

Template Parameters

  • LENGTH – LengthT of input array

  • T – [inferred] The data type to be reduced.

  • ReductionOp – [inferred] Binary reduction operator type having member T operator()(const T &a, const T &b)

Parameters

  • reduction_op – [in] Binary reduction operator

  • prefix – [in] Prefix to seed reduction with
