Hm, they're both (as of your last set) invariant.  Is this so an HPC app
can automatically bind itself or something?  You can't have more than
one such app, or rather if you did, they'd need more than which CPUs are
HPC capable, they'd need occupancy too, so the query mechanism seems
kinda useless.  Box driver has to allocate CPUs, and presumably knows
the configuration of the box (those who don't become ex box drivers).
