Re: [Condor-users] howto avoid that a job is being evicted

[Dan Bradley <dan@xxxxxxxxxxxx>]

Harald,

Yes, you are right.  The RANK expression sets the preferences of the 
machine (i.e. what jobs the machine prefers to run).  The DEFAULT_RANK 
expression sets the default preferences of the job (i.e. what machines 
the job wants to run on).  The machine RANK is the one that can cause 
preemption of jobs unless you adjust other portions of your policy, as 
described earlier in this thread.
