-When testing a new job script, either use an [[http://wiki.chpc.ac.za/quick:start#example_interactive_job_request| interactive job]], on a single node, or a very very short job (maybe 15 mins). This way you will know your job will work, and then you can submit your actual longer job thereafter. You can thus avoid waiting hours or even days to find your job failed, due to perhaps a small error in your input file. Most importantly, **test!**  Please read our section on [[howto:tipsandtricks#please_slow_down_and_work_methodically|working methodically]].+When testing a new job script, either use an [[quick:start#example_interactive_job_request| interactive job]], on a single node, or a very very short job (maybe 15 mins).
