// This benchmark is intended to cover redux instructions on Ampere+ architectures. It specifically uses
// cuda::std::plus<> instead of a user-defined operator, which CUB recognizes to select an optimized code path.

// Tuning parameters found for signed integer types apply equally for unsigned integer types

// __half and __nv_bfloat16 are added for full (non-tuning) runs; CUB has fast paths for them (see #9587).
