I want to know how long does it take to get a submit job scheduled.
Essentially, it's the time interval between submitting a job and the
time the job is executed. Are there any materials/tutorials discussing
Thank you for any help!
There are a number of factors in play here. Typically, if there aer
available resources, you'll probably not even notice a delay. I don't
know of any document that lays out the factors, maybe -
If you're searching around for info, key terms are: negotiation cycle,
claim recycling, claim reuse, reschedule
At a high level, the condor_negotiator periodically starts a negotiation
cycle that hands out resource claims to condor_schedds, who run jobs on
the claims and re-use them between negotiation cycles. Also, when a new
job is submitted a reschedule request is sent to the negotiator, which
may be ignored if it comes in too near to the end of the last cycle (20s
iirc, by default).
