First, the easy part: The WantPslotPreemption attribute is inserted by the schedd into the job ads that it sends to the negotiator to indicate that it understands a pslot preemption match, which involves claiming multiple slots on the execute machine. You shouldnât set it in your submit file. What form of preemption are you expecting thatâs not occurring with pslot preemption enabled, user priority-based or startd rank-based? I just did a quick test with startd rank-based preemption and it worked in my test pool. Thanks and regards, Jaime Frey UW-Madison HTCondor Project |
