Well, it's there but there is no reservation which can be backfilled. As soon as one of the waiting jobs can start it will start. This leads to the observed behavior that some parallel jobs (or a job with a huge memory request) will die of starvation. And to allow backfilling to work correctly, it's best to submit all jobs with an estimated runtime. If the default runtime is used and overdrawn all computed reservation might become worthless. -- Reuti > Going to do some tests... > (I've read some docs about backfill and I did not see where it says > that is't enabled by default...) > >> -- Reuti > Cheers, > Arnau > _______________________________________________ > users mailing list > [email protected] > https://gridengine.org/mailman/listinfo/users _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
