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

[Carsten Aulbert <carsten.aulbert@xxxxxxxxxx>]

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 
favor?

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

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