Detailed Description

MPI reduction operation wrappers.

The functor vocabulary (kamping::ops::), type traits (mpi_operation_traits), ScopedOp, ScopedFunctorOp, and ScopedCallbackOp live in kamping/types/reduce_ops.hpp (the kamping-types module) and are included from there. This file adds ReduceOperation, which selects among these building blocks based on the operation and commutative tag types.
