Subject: Re: [OMPI devel] Funny warning message

I think Lenny is pointing out that "smaller" got changed to "bigger",
too. :-)

Looking at the test in the code (btl_openib_component.c):

             if ((rd_num - rd_low) > rd_win) {
                 orte_show_help("help-mpi-btl-openib.txt", "non
optimal rd_win",
                         true, rd_win, rd_num - rd_low);
             }

So the change in the help message is correct -- it is better when
rd_win is bigger than (rd_num - rd_low).

Ralph -- were you running with a non-default btl_openib_receive_queues?
