Assuming you have more work to do, than the static resources allocated,
you are not wasting any resources. The workflow will run until the
resources are de-allocated, and whatever was not completed, will get
rescheduled on the next round of static resources allocated. As far as
I know, this is the usage pattern of the static resource allocation on
the BG/P for the few regular users, that are running several jobs per
day, where each job is a static resource allocation of 1K~10K
processors for several hours each. Their parameter space is large
enough that they keep doing this over and over again, and they still
more work to do!<br>

Right. Overall it leads to inefficiencies and wasted cpu-hours, but it
gives you a known set of resources, which is valuable. I think the known
set of resources part can be achieved anyway if there was that
back-channel mentioned in random chatter that informed swift about the
nodes available.
