Time is $(date)
Directory is $(pwd)
PBS job ID is $PBS_JOBID
This job runs on the following machines:
$(cat $PBS_NODEFILE | uniq)
$mpirun_command="mpirun $application $options"
#! Run the parallel MPI executable (nodes*ppn)
echo Running $mpirun_command
eval $mpirun_command
In the preceding script, no machine file is needed, since it is automatically built by the workload
manager and passed on to the mpirun parallel job launcher utility. The job is given a unique ID and run
in parallel on the nodes based on the resource specification.

7.2.1 Preliminaries: Loading The Modules Environment
To submit a job to the workload management system, the user must ensure that the following environment modules are loaded:
• If using Torque with no external scheduler:
$ module add shared torque
• If using Torque with Maui:
$ module add shared torque maui
• If using Torque with Moab:
$ module add shared torque moab
• If using PBS Pro:
$ module add shared pbspro
Users can pre-load particular environment modules as their default using the “module init*”
commands (section 2.3.3).
