[Condor-users] Job attribute based preemption

[Horvátth Szabolcs <szabolcs@xxxxxxxxxxxxx>]

Hi,

I disabled preemption altogether in our pool but would like to enable it 
for only a specific type of job.
I'm currently using the rank expression to order the execution of the 
jobs and have user priority
effect only within these job types but would like to have very important 
jobs that do preempt others
(but not each other). I thought that by using an expression for the 
MaxJobRetirementTime I could
control preemption based on job classad attributes but I'm not sure how 
to compare the
attributes of the currently running job to the new job to decide whether 
preemption should happen.

Is it possible at all what I'd like to do or do I have to use a 
completely different method to achieve
job attribute based preemption?

Cheers,
Szabolcs
