Hoffman2:Job Array

Back to Hoffman2 Batch Mode

Job Array or Array jobs make it possible to process different subjects/files using the same script on multiple Hoffman2 working nodes at the same time.

Here, we use the this template code to show how it can be done Submit job

#!/bin/bash
#$ -cwd
# error = Merged with joblog
#$ -o joblog.$JOB_ID
#$ -j y
#$ -pe shared 2
#$ -l h_rt=8:00:00,h_data=4G
# Email address to notify
#$ -M $USER@mail
# Notify when
#$ -m bea
#$ -t 1-50:1

The only difference comparing with the single subject version is this part

 #$ -t 1-50:1

The -t option should be in this format

-t lower-upper:interval

where

lower

is replaced with the starting number

upper

is replaced with the ending number

interval

is replaced with the step interval

So adding the argument

-t 10-100:5

will step through the numbers 10, 15, 20, 25, ..., 100 submitting a job for each one.
