[Condor-users] Vanilla jobs get preempted and restart from begining (because of user priority)

["Rob Stevenson" <r.stevenson@xxxxxxxxxxxxxxxxxxx>]

Dear users,

I have recently put condor into production servers here. Everything runs nicely except when we get long runs submitted - only recently have we started using condor for longer runs.

 

All the runs affected are in the vanilla universe and over 10 hours long. We currently have 4 servers that have the requirements needed for these jobs to run.

 

What is happening is that user1 may submit 4 jobs which run fine for a few hours. But then user2 submits a job, and one of user1's jobs gets stopped so that user2's job can run. I understand this is a result of user priorities*. The problem is that when the initial run that was stopped goes to restart, it starts from the beginning.

 

Some of these longer jobs will never actually finish given that new jobs from new users are being regularly submitted.

 

I have tried adding the following to condor_config.local on the four servers. But it appears to still do the same thing.

PREEMPTION_REQUIREMENTS = False

 

I think the best way to solve this would be to prevent runs from being stopped at all, and just letting them continue running to the end. Does anyone have any suggestions?

 

The servers are:

$CondorVersion: 7.0.1 Feb 27 2008 BuildID: 76180 $
$CondorPlatform: INTEL-WINNT50 $

 

Desktop (the user that submits the jobs)

$CondorVersion: 7.0.0 Jan 22 2008 BuildID: 72173 $
$CondorPlatform: INTEL-WINNT50 $

 

The condor master:

$CondorVersion: 7.0.0 Jan 22 2008 BuildID: 72173 $
$CondorPlatform: INTEL-WINNT50 $

 

Sorry I haven't provided any more specifics, I really don't know what would be useful and don't want to drown you in useless output! Let me know if there is anything else that would help!

Thanks for any advice,

 

Rob
