[slurm-users] Billing issue

Hello all.

How can I configure Slurm to bill users for the actual "percentage" of a
node's use?

I mean that an user requesting one core and all the RAM should be billed
for the whole node, since the other cores can't be allocated to another job.
The ideal would be to bill max(ReqCores, ReqMem * MaxMem/TotalCores) .

To make things harder, on another partition I'd need to bill for a
minimim of 1/4 of the cores and 1/4 of the RAM (to discourage serial
jobs in favor of parallel ones), but keeping the same logic above: an
user requesting 1 core and 2G RAM will be billed 1/4 of the node.

Is it doable? It's a couple weeks I'm looking at the docs, but I still
miss something...
