 ====== Submitting Many Jobs ======
+You may need to run many (possibly similar) tasks on the cluster. You can do this by submitting each job separately to the cluster, techniques for doing that are discussed below. You could also do it by submitting a small number of jobs (possibly even just one) and have those jobs execute the many tasks you need to run. You should try not to submit thousands of separate jobs into the queue.
 To submit many jobs to the cluster you can:

 Some other options for limiting the number of cores your jobs use are described below.
+==== Singleton Jobs ====
+You can use the **--dependency** option of sbatch to make slurm run just one of your jobs at a time. Suppose you submit 10 jobs with the same job name, using the **--dependency=singleton** option will make slurm run these jobs one at a time.
+<code>
+for i in $(seq 1 10); do
+sbatch --job-name oneatatime --dependency=singleton my_script.bash file_${i}.fasta
+done
