Sets the initial priority of your job step. Priority only affects your job steps. It orders job steps you submitted with respect to other job steps submitted by you, not with respect to job steps submitted by other users.
The syntax is:
user_priority = number
where number is a number between 0 and 100, inclusive. A higher number indicates the job step will be selected before a job step with a lower number. The default priority is 50. Note that this is not the UNIX nice priority.
This priority guarantees the order the jobs are considered for dispatch. It does not guarantee the order in which they will run.
