Yes, the combination of the things you mentioned should allow you to
run on the BG/P with policies that restrict you to only a few jobs in
the queue, where each job will generally contain a large portion of the
allocation in terms of number of processors. <br>

the BG/P, I'd argue for implementing static provisioning,

I see there's still some confusion about "static provisioning". Perhaps
we should abandon the term. Instead we could use:
1. pre-defined window, in which we say when the system should try to
allocate nodes, in what amount, and for how long.
2. moving window, in which the system decides when to allocate nodes and
for how long, subject to certain constraints (such as 64 nodes per job,
8 cores per node).
3. mixed mode, in which pre-defined windows could be used if available,
and supplemented by moving windows if necessary.
