Re: [condor-users] priority problem

[Alexander Klyubin <A.Kljubin@xxxxxxxxxxx>]

I think the problem is that you first submit a job with lower priority. 
Condor starts it. Then you submit a job with higher priority. However, 
Condor does not preempt jobs of the same user with lower priority, as 
far as I can tell.
