Hi Agian.

I got it.

 Preemption by rank is a normal preemption, I came this morning to the office and all is working as excepted for now -:)

Preemption_requirements = SubmitterGroup =?= RemoteGroup && RemoteUserPrio > submitterPrio * 1000

ALLOW_PSLOT_PREEMPTION = True.

Thanks

Subject: Startd Rank and Preemption

 

HI All,

I'm trying to do a preemption from the execution point while setting the "Rank = TARGET.AcctGroup == "groupa""

The execution point has 8 gpus  

While the execution point is running 8 jobs "Single GPUs" and user from groupa sending a job with a single gpu it preempt a single slot and working as expected.

While the execution point is running 8 jobs "Single GPUs" and user from groupa sending a job with 8 GPUs it does not preempt as expected.

I have noticed that if I'm setting "ALLOW_PSLOT_PREEMPTION = True" at the negotiator it preempt the job but does not start the correct one it looks like the claim is gone and it starts jobs from other groups.

Some information.

condor_version 23.0.3

slot_weight = GPUs ( I don't think  its related )

Using Pslots

Thanks

David
