With these calls in Solaris you can bind processes, threads, tasks, projects
and zones according to the idtype. In our case it would be only process and
threads. Please see pset_bind(2) and processor_bind(2) man pages.

Can you explain "external setting"?
Please note, that there would be a schedctl(8) (or kind of such tool), where
administrator could bind the set of CPUs for application(s). Why do you think
it is a bad idea?
