====== 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 possible for the partition you are submitting to (''sinfo'' will tell you what the partition limit is); e.g. if you need 60 hours and the partition only allows up to 48, then set //48// hours in your script)
   * Submit your job to the scheduler with the --hold syntax;

<code lang=shell-session>
$ sbatch --hold myscript
</code>

   * Your job will be submitted, but not scheduled.
   * Take a note of the new Job ID and submit a service request ticket via the [[http://nuservice.ncl.ac.uk|NUIT ITService]] self-service system.
   * Tell us __why__ you are requesting the extension, the __new time limit__ you want, 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.
