Did you take a look at the “claim” time? Sometimes, machines remain allocated even after job completes assuming the same user may fire another job. This time is configurable. Just check this out, in case if this is your problem. Oh Sorry, I missed the interval part. Can you tell me which section in the manual?

Subject: Re: [Condor-users] Fast job execution and matchmaking Hi,
Using the vanilla universe.
As i understand from the manuals and config files the smaller the intervals, the faster the job
will find the proper home.
if i schedule 100 of the same job (queue 100), they do run faster (not 100*8 sec) but its not the case in our lab.
we run individual jobs....
Thanks,
Guy.

I don't think Intervals are related to job scheduling latency though I may be wrong.
I think it is better you keep the intervals back to 300.
Did you ever try with the default intervals?
Do you observe 9 second latency for each and every job that you fire?
Did you try firing jobs continuously in a shell script (say some 100 jobs) and see what happen?
Best Regards,

Hi!
We have a local condor pool in our university lab.
a condor master and several quad core computers
(all with the same hardware).
We want to run many small condor jobs, and we want
very fast matchmaking/execution.
I did set all the intervals in the config file to
1sec (instead of 300). we don't care about the network
traffic between them because it is just 20 cores and not 2000.
The weird thing is it still takes 8 or 9 seconds
until a job executes...
Any way to make it faster? maybe a config parameter
that i am missing?
Could i set an interval of under 1 second?
Maybe i can change something in the source codes?
Sorry about all the questions..... hoping that someone can help.
Thanks,
Guy
