Re: [Condor-users] Job attribute based preemption

[Horvátth Szabolcs <szabolcs@xxxxxxxxxxxxx>]

Hi Dan,

But I do have to lower the MaxJobRetirementTime if I want to make the 
preemption instantaneous, don't I?
If I only modify the start expression I get the preemption happening 
(actually almost all of my running jobs
are already preempted because of the rank expression we use) but it is 
not instant.

Cheers,
Szabolcs
