Well, any resource should be put into the nodes file. Specifying the resources
on the server instead on the node makes sense. I personally don't really like
the resources specified in node configuration file (although I guess, some
admins might prefer this).

Well yes. NP's are treated as slots. That makes sense for CPUs, but not really
for anything else. GPUs can be still treated as slots, but there won't be no
slot mapping (because each slot for NP has its own sub-node).
