Note that the slot weight expression is typically configured to correspond to the "most limiting" resource, and furthermore behaves as a _measure of the number of potential matches remaining on the partitionable slot_.
{subsubsection: Fast Slot Loading}
-When the HTCondor negotiator matches a job against a partitionable slot configured with a consumption policy, it will deduct the resource assets (cpu, memory, etc) from that p-slot and keep it in the list. Therefore, a p-slot can be matched against multiple jobs in the same negotiation cycle. This allows p-slots to be fully loaded in a single cycle, instead of matching a single job per cycle. (Note, the CLAIM_PARTITIONABLE_LEFTOVERS feature is an alternative approach to faster p-slot loading, operating in the scheduler as opposed to the negotiator).

{subsubsection: Flexible Quota Utilization}
+The cost of matching a job against a slot is traditionally the value of the SlotWeight expression. In a scenario where the slot weights of available p-slots are greater than an accounting group's quota, the jobs in that accounting group will be starved.
+However, when a p-slot with a Consumption Policy is matched the match-cost is the _change_ in the SlotWeight value, from before the match to after. This means that a match is _only charged for the portion of the p-slot that it actually used_ (as measured by the SlotWeight expression), and so p-slots with many resources and possibly large SlotWeight values can generally be used by accounting groups with smaller quotas (and likewise by submitters having smaller fairshare values).
