Hi all -

A quick question about MPI_Group_range_excl(). I notice that if for a
given triplet, first_rank == last_rank, we error if stride is not 1. I
notice we don't have that test in MPI_Group_range_incl(). Is there a
reason that test should be there - the standard doesn't seem to imply
that stride must be 1 if first_rank == last_rank.
