-By default, BOINC processes jobs in a roughly first-in, first-out order.
-If your project has multiple job submitters,

-users who submits lots of jobs would get more than their share of the project's capacity.
-BOINC has a set of mechanisms that address this issue.

+If you use [RemoteJobs remote job submission], read no further;

-Create a user account for each job submitter,

- * Set job priorities.  For example, use the '''--priority''' option to '''create_work'''.
-   Also, if you're creating a batch, set batch.logical_end_time to the priority
-   (this is not used for scheduling, but is used in displaying batches on the web).
-
-== Prioritize existing jobs ==
-
-If you have a lot of jobs already queued,
-you can prioritize them (and initialize user priorities) by running

-
-This script can also be used to reset all priorities to zero.
-
-== Use the right feeder options ==
-
-Run the feeder with the '''--priority_asc''' option.

-Notes:
- * Currently this can't be used in combination with the --all_apps option,
-  or with homogeneous redundancy.
- * If there are any problems, remove the '''--priority_asc''' option
-  and you'll be using FIFO again.
+ * Set job priorities to this value.  For example, use the '''--priority''' option to '''create_work'''.
