On Behalf Of Yuval Leader Hi, I am finally in a position to verify the allocations kindly described by Ian Chesal on 22-aug (see thread below). I am trying to verify that a fair share of resources is indeed matches to 2 users with same user priority, both with job numbers of same job priority I expect that a limited set of equal resources will be shared 50-50 between the users. The actual result I’m seeing is that one user still gets all its requests filled. background The machine I have has 16 cpus’ thus giving me 16 slots. I have assigned a STARTD_ATTR to just 8 of the slots: MT_Model = "PowerEdge 1850". The other 8 slots have different values for this attr. MY Test flow: 1.
2 users are assigned the same user priority 2.
First user submits a cluster job with ‘queue 5’ and job requirements is: TARGET.MT_Model =?= "PowerEdge 1850" 3.
Second user submits a cluster job with ‘queue 6’ and same job requirements is: TARGET.MT_Model =?= "PowerEdge 1850" 4.
I expect that each will get exactly 4 slots and have remaining jobs un-matched 5.
Actually what I see is that the second user gets all its requested 6 slots and the other gets 2, with 3 jobs un-matched I would like to understand what I’m doing wrong here….. Test Flow Commands: Users priority is set to equal value: >condor_userprio -setprio
eitan@xxxxxxxxxxx 3 The priority of eitan@xxxxxxxxxxx was set to 3.000000 >condor_userprio -setprio

Add another assumption and yes, this is what you'll see. The other assumption you need to add is that all four users have the exact same effective user priority. See:
http://research.cs.wisc.edu/condor/manual/v7.6/3_4User_Priorities.html#25902 If they all have the same EUP, they'll all get exactly 1/4 of the system after one negotiation cycle assuming everything about their jobs is equal. This is easy enough to test. I queued up 10 sleep jobs from four users in a new pool that has four slots available in it. None of these users had accumulated any use history so all had identical EUPs of 0.

Yes. This is what will happen. Again, assuming their EUPs are all equal.
No, that's not what happens. The negotiator determines up front, using the EUP of each submitter, what each submitter's fair share of the machines should be for this negotiation cycle. And based on that it moves through each submitter's
list of idle jobs and tries to match them to slots. If the EUPs of your users aren't all identical then the allocations will not be equal. Some users will get more because they've used less in the recent past. Some users will get less because they've used more in the recent past.
Only if you also add the assumption that all EUPs are identical for the users.
Accounting groups help ensure that, regardless of EUP, people get some minimum (and possibly maximum) number of slots in your pool when they have jobs in a queue. If you wanted each user to always get 50 machines, but user >50 machines if other users aren't using their machines, you'd setup soft quotas for 4 different groups and put each user in a unique group. Now, Condor will attempt to fulfill
their quotas first and, once all the quotas have been satisfied, it'll let excess free resources be used, fair share, but anyone who has a soft quota limit.
