+#### Dependency Job Submission
+
+To submit dependent jobs in sequence, use the `depend` function of `qsub`.
+
+First submit the first job in a standard manner:
+
+```console
+$ qsub -A OPEN-0-0 -q qprod -l select=64:ncpus=36,walltime=02:00:00 ./firstjob
+123456[].isrv1
+```
+
+Then submit the second job using the `depend` function:
+
+```console
+qsub -W depend=afterok:123456 ./secondjob
+```
+
+Both jobs will be queued, but the second job won't start until the first job has finished successfully.
+
+Below is the list of arguments that can be used with `-W depend=dependency:jobid`:
+
+| Argument    | Description                                                     |
+| ----------- | --------------------------------------------------------------- |
+| after       | This job is scheduled after `jobid` begins execution.       |
+| afterok     | This job is scheduled after `jobid` finishes successfully.  |
+| afternotok  | This job is scheduled after `jobid` finishes unsucessfully. |
+| afterany    | This job is scheduled after `jobid` finishes in any state.  |
+| before      | This job must begin execution before `jobid` is scheduled.  |
+| beforeok    | This job must finish successfully before `jobid` begins.        |
+| beforenotok | This job must finish unsuccessfully before `jobid` begins.      |
+| beforeany   | This job must finish in any state before `jobid` begins.        |

 ### Salomon - Intel Xeon Phi Co-Processors
 
 To allocate a node with Xeon Phi co-processor, the user needs to specify that in the select statement. Currently only allocation of whole nodes with both Phi cards as the smallest chunk is supported. A standard PBSPro approach through the `accelerator`, `naccelerators`, and `accelerator_model` attributes is used. The `accelerator_model` can be omitted since on Salomon, only one type of accelerator type/model is available.
