OK I probably need to brush up my English :-)

Yes, that is exactly it. You can only request resources for the whole job in
Torque. That's OK for resources that have no location (like licenses). Not so
much for resources that belong to nodes.

The patch is a modification of the pbsnode structure (two resource attributes).
The server parameters are just a convenience, but the whole point of the patch
is to be able to specify resources, that are not reported by the nodes. This is
extremely useful because it allows admins to very quickly specify new counted
resources (for example: disk space, special hardware...).
