The Tasks field on the Set Hold dialog box applies to Array jobs. Use this button to put a hold on particular subtasks of an array job. Note the format of the text in the Tasks field. The task ID range specified in this field can be a single number, a simple range of the form n-m, or a range with a step size. The task ID range specified by, for example, 2-10:2 results in the task ID indexes 2, 4, 6, 8, and 10. This range represents a total of five identical tasks, with the environment variable SGE_TASK_ID containing one of the five index numbers. For detailed information about job holds, see the qsub(1) man page.
