qsub parallel running

I have downloaded and installed the software of I-TASSER in my compute. There are still some questions for running by parallel of it. I have read the code of the file runI-TASSER.pl and I found it submit parallel running by the following command:
######
$bsub=`qsub -e $errfile -o $outfile -l $walltime -N $tag $jobname`;
$bsub=`qsub $datadir/$tagnames{$i}`;
######

However, we use qsub by another type, such as qusb –cwd –l ….. , and we always submit the job by qsub –cwd –l vf= … *sh other than sh *.sh . Therefore, it may be some trouble to do parallel running in our lab. And If there are some methods to solve it?
