qsub job array, where each job uses a single process?

Question

I have a job script with the following PBS specifications at the beginning:

#PBS -t 0-99 #PBS -l nodes=1:ppn=1

The first line says that this is a job array, with jobs indexed from 0 to 99. I want each individual indexed job to use only a single node and a single core per node, hence my second PBS line. But I am worried that TORQUE qsub will interpret the second line as saying that the whole job array should run sequentially on a single core.

How does TORQUE qsub interpret the PBS second line?

It interprets it as 100 jobs that should each use 1 execution slot on one node. For more information, please look at the qsub documentation and look for the details on the -t switch.

i'm wondering if you can comment on the use of job array vs something called bundling described here: sdsc.edu/support/user_guides/tscc.html#bundling-serial, which one is more efficient to use?
