====== Job dependencies ======

SLURM allows you to define different kind of dependencies between jobs, for instance to make sure that certain jobs will run only if another job succeeded/failed. The dependencies can be added to your job script using the following line:

<code>
#SBATCH --dependency=type:jobid1:jobid2:jobidN,type:jobid1:jobid2:jobidN,...
</code>
The job id should belong to an already submitted job, while type should be one of the following:

|**Type**  |**Meaning**                                                                                                                                           |
|after     |Start this job after the specified jobs have started                                                                                                  |
|afterany  |Start this job after the specified jobs have completed                                                                                                |
|afternotok|Start this job after the specified jobs have failed                                                                                                   |
|afterok   |Start this job after the specified jobs have successfully completed                                                                                   |
|expand    |Use this job allocation to expand the job allocation of the specified job (just one, must be in the same partition and have a similar wall clock time)|
|singleton |Start this job after all previously submitted jobs with the same name have completed                                                                  |
