==Job Arrays==<br />
Stolen from [http://www.ats.ucla.edu/clusters/common/computing/batch/job_arrays.htm Job Arrays]<br />
<br />
The Sun Grid Engine (SGE) has a job array option, which lets you submit multiple jobs with a single command file.<br />
Syntax for this magical wizard is:<br />
#$ -t lower-upper:interval<br />
<br />
<br />
''''' example '''''<br />
Command:<br />
qsub -cwd -V -t 1-2:1 hellotask.sh<br />
<br />
File: hellotask.sh<br />
<nowiki><br />
#!/bin/sh<br />
<br />
echo "Task id is $SGE_TASK_ID"<br />
if [ -e $HOME/JOBARRAY/data$SGE_TASK_ID.in ]; then<br />
while read file<br />
do<br />
echo "hello $file"<br />
done < $HOME/JOBARRAY/data$SGE_TASK_ID.in<br />
fi<br />
</nowiki><br />
<br />
<br />
File: data1.in<br />
first<br />
second<br />
<br />
File: data2.in<br />
third<br />
fourth<br />
<br />
When the value of $SGE_TASK_ID is 1, the hellotask.sh script will output:<br />
Task id is 1<br />
hello first<br />
hello second<br />
<br />
When it is 2, the output will look like:<br />
Task id is 2<br />
hello third<br />
hello fourth</div>
