Comment (by Alain Miniussi <alain.miniussi@…>):

 One solution could be to transparently test for equality of the two
 buffers and silently pass MPI_IN_PLACE to MPI_Allreduce, another could to
 provide a boost mpi_in_place object with automatic conversion to T*.
 The first one is probably a no-brainner for user, but then, something
 explicit in MPI is made implicit in boost mpi.
 I can provide the patch, other operation could be concerned.

 Regards,
