[HTCondor-users] manipulate ranking/priority of very-short-jobs-users

["Beyer, Christoph" <christoph.beyer@xxxxxxx>]

Hi,

for a long time we deal with people that are sending ultra-short jobs with a runtime of a couple of seconds (I assume they are looking at one ntuples or something similar). 

These jobs cause probably more overhead computing time than goodput and give reasons for shared FS trouble every now and then. I would like to educate the users and make very short jobs un-attractive. 

I was looking for something like 'max_jobstarts_per_user' (which does not exist) or a way to alter the slotweight and the priority by counting every jobstart like a full 3h running job in order to give these people a really bad priority but so far did not find a propper way to do so :( 

Any ideas somebody ? 

Best
christoph
