In LSF, attributes that impact scheduling decisions are often attached to 
queues.

In Condor, attributes that impact scheduling decisions are attached 
_directly_ to either jobs (job ClassAd attributes) or to resources (machine 
ClassAd attributes).   Every individual job can have its own "policy", 
because in Condor every job can specify its own Requirements and 
Rank.  Ditto for every resource (machine).    So each individual job can 
describe itself and what sort of policy it desires, and each machine can 
describe itself and what policy it desires.  It is a different conceptual 
model, and may take some getting used to if you are moving from the LSF 
environment, but it allows for a lot of flexibility for users & owners, 
with minimal intervention needed on the part of admins [or so we hope... ;) ].

So with Condor it is not typically necessary to create multiple queues to 
support different policies.

Todd
