How do I run a job for longer than allowed?

Sometimes it is necessary to run a job for longer than the defaults for a partition allow. In these cases we recommend you follow these steps:

Write your SBATCH job with the runtime you need (not what the partition limits you to; e.g. if you need 60 hours and the partition only allows up to 48, then set 60 hours in your script)
Submit your job to the scheduler with the –hold syntax;

$ sbatch --hold myscript

Your job will be submitted, but not scheduled.
Take a note of the new Job ID and submit a service request ticket via the NUIT ITService self-service system.
Tell us why you are requesting the extension and include the Job ID.
As long as your supporting rationale is reasonable, one of the RSE team will arrange to apply the extended runtime to your job, and then release it to be scheduled.
