It depends on what you are trying to do. Rankfile is really only useful if you need to specify rank-by-rank precise bindings. Otherwise, you can specify bind-to-core or bind-to-socket to get a more general automatic binding pattern. You can also specify cores-per-task and get each process bound to the specified number of cores.
So there are a lot of options, including rankfile. Unfortunately, I see that these options are not documented on the FAQ or the wiki. :-/
Take a look at "man mpirun" and you'll see more info about all this in the part on process binding options.

No offense taken :-) I appreciate your efforts and I understand your
