If your work consists of a large number of tasks which differ only in some parameter, you can conveniently submit many tasks at once using a <i>job array,</i> also known as a <i>task array</i> or an <i>array job</i>. The individual tasks in the array are distinguished by an environment variable, <code>$SLURM_ARRAY_TASK_ID</code>, which Slurm sets to a different value for each task. You set the range of values with the <code>--array</code> parameter. | If your work consists of a large number of tasks which differ only in some parameter, you can conveniently submit many tasks at once using a <i>job array,</i> also known as a <i>task array</i> or an <i>array job</i>.
