the documented (in the FAQ) affinity-related one at least for the

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.

I've applied to a 1.4.1 tree the patches from tickets #2318 and #2321
and I can confirm that both problems reported earlier are fixed.
Thanks - appreciate the confirmation!

No offense taken :-) I appreciate your efforts and I understand your
frustration about unmaintaned code. Thanks again !
