Your job was assigned 2 nodes and was executed correctly.

PBS doesn't run your script on every node in your job, only on the
*first* node in the job.  It is the responsibility of your script to
spawn processes on the assigned nodes.  You can do this with the pbsdsh
utility for simple stuff, or use $PBS_NODEFILE for complicated stuff.

echo 'pbsdsh hostname' | qsub -l nodes=2
