How do I run a job for more that 10 days?

The simple answer is that you can't - the maximum run time for jobs on the DCSR clusters is 10 days and this limit will not be extended.

If you think that you need to run for longer than ten days then please do the following:

We will then get in touch with you to analyse your code and suggest performance or workflow improvements to either allow it to complete within the required time or to allow it to be run in steps using checkpoint/restart techniques.

Recent cases involve codes that were predicted to take months to run now finishing in a few days after a bit of optimisation.
