[HTCondor-users] Multiple negotiators : which one wins?

[Jeff Templon <templon@xxxxxxxxx>]

Yo,

How do multiple negotiators work at the innards level?  Suppose we have two negotiators, each that covers half of the pool.  Both have the same ranking expressions.  A job is submitted that could run anywhere in the pool, so both negotiators could in principle deal with it.  What determines which one wins?

Does the job get given to only one negotiator for matching, or to both?  Suppose one negotiator is on a slower machine than the other, will that make a difference? Suppose I change the rank expression on one of the negotiators so for that job, the changed negotiator will report a higher rank for the job than will the other negotiator, will the changed one always win?  Or does the rank only matter internal to the negotiator, the job doesnât get a chance to say âthis negotiator gave a higher rank then this other one, highest rank wins?â

Iâm trying to correct an adverse consequence of our negotiator setup using ranking.  Since there is no node overlap between the negotiators, it seems that ranking is the only tool I have, but Iâm not sure it makes a difference between negotiators, hence the question.
