Detailed Description

template<typename SizeType, typename IndexType, IndexType N>
struct Kokkos::reduction_identity< ParticleBinning::ArrayReduction< SizeType, IndexType, N > >

Kokkos reduction identity specialization for custom reduction types.

These specializations of Kokkos::reduction_identity are required to enable the use of custom ArrayReduction types with Kokkos built-in reducers. The reduction identity function provides the neutral element for the reduction operation, which serves as the initial value for thread-private reduction variables.

Note

The GPU version (ArrayReduction) uses compile-time fixed arrays, while the host version (HostArrayReduction) uses dynamically allocated arrays for flexibility with runtime-determined sizes.
