Example job script

This is for TESTING purposes only

Once you have this process working, you MUST start using your own campus licenses, as per the second example script.

fekorun.qsub
#!/bin/bash
### This example script uses 2 compute nodes. 
### If only one node is being used, set #PBS -q smp (24 cores)
### Or #PBS -q serial to for a few cores (<24) on a shared node
#PBS -l select=2:ncpus=24:mpiprocs=24:nodetype=haswell_reg
#PBS -P MECH****
#PBS -q normal
#PBS -l walltime=1:00:00
#PBS -S /bin/bash
#PBS -o /home/user/scratch/fekotest/fekostdout.txt
#PBS -e /home/user/scratch/fekotest/fekostderr.txt
