Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

Function template operator!=

boost::mpi::operator!= — Compare two allocators for inequality.

template<typename T1, typename T2> 
  bool operator!=(const allocator< T1 > &, const allocator< T2 > &);

Since MPI allocators have no state, all MPI allocators are equal.

Returns:

false
