Re: [Condor-users] Job remains in idle (worked until I increased pool size)

["Michael O'Donnell" <odonnellm@xxxxxxxx>]

I found a ticket posted on the Condor
wiki, and my error sounds similar (https://condor-wiki.cs.wisc.edu/index.cgi/tktview?tn=1645).
I am not sure why we are now seeing this problem, because we have been
using 7.4.3 since it was released and we are still using it. The only change
I made was adding 100 cores to the pool.

The ticket states there have been sporadic
reports and nothing has been confirmed and therefore I believe it remains
open.

Any ideas?

thanks,
mike

We added machines to the pool (about 70).

As for the second comment, we did not change anything and we require use
run_as_owner = true.

thanks

Hi Michael,

I expanded the pool from 100 cores to 200 cores and since than any jobs

How did you expand the cores? By doubling the slot counts on your machines
or by adding new machines? 

I ask because... 
  
1   ( ( ( 1024 * target.Memory ) >= 4500 ) && ( ( 1024
* ceiling(ifThenElse(JobVMMemory isnt undefined,JobVMMemory,4.394
531250000000E+000)) ) >= 4500 ) ) 
                    
                 0  
                REMOVE

That above statement says there are no machines with enough memory to run
your jobs. If your slot count was doubled by doubling slots advertised
by your pool's machines, then you've halved the memory allocated per slot
by Condor and possible constrained yourself out of slots because of this.

  
2   ( target.HasWindowsRunAsOwner && ( target.LocalCredd is
"CM" ) ) 
                    
                 0  
                REMOVE

This one I cannot explain. Did you change submissions to use run_as_owner
= true?
