Re: [Condor-users] When is machine RANK evaluated? Was: Rank expressions not evaluated

Hi Carsten,

Machine rank should trump user priority, so it should not be necessary for user B to have a better EUP than user A in the scenario that you describe.

Hi all

essentially this is just a rewrite of Henning's question, but in a somewhat
broader scope:

I think we understand the negotiation cycle to some extend, but we don't know
under which circumstances the machine RANK is evaluated. It seems it will ONLY
be evaluated if the effective user priority (EUP) is sufficient to exceed at
least the "fair share quota".

At least we discovered that this seems to be true, i.e. user A has an EUP of
1000 and user B of 100000 and we have 8 slots user A gets all. However, we
want to give user B the possibility to move into certain slots and hence set
the machine RANK to something like this:

Rank = IfThenElse(WantGPU =?= true,1000,0)

(also with prefix TARGET.)

User A does not have this set, should thus have a lower Rank than User B (me),
however, it seems this does not help:

Can I infer from this that RANK is never evaluated unless EUP also is in

(We are currently resorting to GROUPs ttrying to resolve this but so far to no

Anyone who can shed some light what we are doing wrong?
