ValLocScalar¶
ValLocScalar is a class template that stores a value and its
corresponding location (index) as a single, convenient unit. It is
primarily designed to hold the result of parallel_reduce() operations
using the MinLoc and MaxLoc builtin reducers.
It is generally recommended to get this type by using the reducer’s
::value_type member (e.g., MaxLoc<Scalar,Index,Space>::value_type) to
ensure the correct template parameters are used.
Header File: <Kokkos_Core.hpp>
Usage¶
MaxLoc<T,I,S>::value_type result;
parallel_reduce(N,Functor,MaxLoc<T,I,S>(result));
T resultValue = result.val;
I resultIndex = result.loc;
Interface¶
-
template<class Scalar, class Index>
struct ValLocScalar¶ - Template Parameters:
Scalar – The data type of the value being reduced (e.g.,
double,int).Index – The data type of the location or iteration index (e.g.,
int,long long).
