Jobs on the Hoffman2 Cluster are limited by the time that they can run. This can be as short as 24 hours. If an application that you have written yourself needs to run longer than this, it will have to save appropriate information periodically in a restart file so that it can be resubmitted after it has been terminated and restarted from where it left off.
If you need assistance doing this, please contact the High Performance Computing consultants at firstname.lastname@example.org. The consultants respond to email sent to this address during normal business hours.
