Detailed Description

template<typename Op, typename T>
struct boost::mpi::is_commutative< Op, T >

Determine if a function object type is commutative.

This trait determines if an operation Op is commutative when applied to values of type T. Parallel operations such as reduce and prefix_sum can be implemented more efficiently with commutative operations. To mark an operation as commutative, users should specialize is_commutative and derive from the class mpl::true_.
