Running in multiple node

Dear all,
I have a cluster with 12 nodes, each node is having 2 processor with total 16 core.
I wanted to run a simulation/job using 1+ nodes. Can anyone tell me how to do that?

qsub -l select=1:ncpus=16   <your simulation script to run across one node >

qsub -l select=2:ncpus=16  <your script to run across 2 nodes >

qstat -answ1 # to know the status of your jobs

Hope this is helpful
