The Job Defaults tab lists the defaults for a job when no preference is made for the listed parameters.
Scheduling Priority
Specifies what the job scheduling priority is set to if no priority is specified at submission. The allowable priority range is -1024 to 1023.
Execution Priority
Limits the execution priority of jobs submitted to the selected queue. You can select Idle, Normal, High, or Realtime execution priority. The default execution priority for newly created queues is Normal.
A Realtime process preempts all other processes, including the operating system. Intergraph
recommends that you avoid using the Realtime priority.
