Re: [Condor-users] idling jobs

["Daniel Goldin" <Daniel.Goldin@xxxxxxx>]

Thanks, Nick, for your reply.

I've run 'condor_q -better' on the farm as you suggested. I'm attaching
the output. I'm not an expert enough to understand it though. Can you
glean something from it?

Thanks in advance,
Daniel

There's not a lot of information here, and there could be quite a lot of 
things going wrong.

First, have you waited at least one negotiation cycle (typically 5 minutes)?  
I'm assuming that these are all long running jobs (from your description 
above).  Condor doesn't do particularly well when users submit a lot of short 
running jobs.  If that's not the case, then let's try a couple debugging 
exercises:

1. Have you looked at the output of 'condor_status' to verify that all of the 
execute machines are reporting to the pool correctly, and that they're all in 
the unclaimed / idle state?

2. Have you tried running 'condor_queue -analyze' or (even 
better) 'condor_queue -better' (better analyze) and looked through it's 
output?

I'd start with the above two exercises...   If they don't help, give us a 
little more information to go on (like the output of condor_status and 
condor_q or 'condor_q -ana').

Hope this helps

-Nick
