 In PBS scripts, the ''​ppn''​ parameter is very important. If the requested value of ''​ppn''​ is larger than the number of cores per node present on the hardware, the job will never run and will stay queued until deleted. In practice, you should almost always use ''​ppn''​=8 on 8core queues, ''​ppn''​=12 on 12core queues, and so on. If ''​ppn''​ is smaller than the correct value for the queue, the job will run, but will not use all the cores, if you are calculating the number of mpirun threads as in the example script above. In PBS scripts, the ''​ppn''​ parameter is very important.

 The completed job script can be submitted to the scheduler with the ''​qsub''​ command. The name and extension of the script are arbitrary. If the script is called MPI-test-script.pbs,​ you will run ''​qsub MPI-test-script.pbs''​. To check the status of jobs, use the interactive commands ''​showq''​ or ''​checkjob''​. The ''​showq''​ command will print general information about the state of the job queue. The completed job script can be submitted to the scheduler with the ''​qsub''​ command.
