Re: [condor-users] priority problem

[Mark Silberstein <marks@xxxxxxxxxxxxxxxxxxxxxxx>]

Pablo,
Unlike LINUX/UNIX systems, Condor uses the following priority scheme:
<The following is FROM the `man condor_submit`:
  priority = <priority>

          Condor  job  priorities  range  from -20 to +20, with 0
          being the default. Jobs with higher numerical  priority
          will  run  before  jobs  with lower numerical priority.
          Note that this priority is on a per user basis; setting
          the priority will determine the order in which your own
          jobs are executed, but will have no effect  on  whether
          or not your jobs will run ahead of another user's jobs.


Cheers,
Mark
