Re: [HTCondor-users] Slot weights

[Jeff Templon <templon@xxxxxxxxx>]

Actually, itâs not clear whether the slot weight affects the priority.  It does affect the weighted in use values and total usage values printed by condor_userprio, but the documentation does not say anything about the effect of slot weight on priority, even though that effect would be The Right Thing To Have.

Gurus?
