NEMO says "no resubmit required" when run is not complete

Reported by: iwi Owned by: ros
Component: NEMO/CICE Keywords: resubmission
Cc: Platform: HECToR
UM Version: 7.5

Description

I imagine this is probably very basic, but I'm stuck.

I'm experimenting with running NEMO under the UMUI, using a copy of test job xevjc (see xerae or xeraf), based on the assistance you gave me in person at Reading a while ago. My understanding from your documentation at http://puma.nerc.ac.uk/trac/NEMOCICE is that the total run length is specified from the UMUI - certainly the namelist just says

nitend      =      set_by_umui   !  last  time step

However even though I set in the UMUI a total run length which exceeds the run length for each job in the resubmission sequence (in this example, 2 months with resubmission every 1 month), and have resubmission turned on in the UMUI, when it gets to the end of the first job it reports in the leave file:

Attempting nemo resubmit.......
/work/n02/n02/iwi/um/xerae/bin/qsresubmit: No resubmit required

when it clearly hasn't finished the run.

What am I doing wrong please?

Many thanks.

Hi Alan,

I believe automatic resubmission of NEMO/CICE jobs work in the same way as for the atmosphere. NRUNs and CRUNs are controlled through the UMUI and should work in the same way as for the atmosphere model.

See http://puma.nerc.ac.uk/trac/NEMOCICE/wiki/RunningNemo (bottom of the page)

The first job you submit is an NRUN which will stop after the first submission period of 1 month.

To create a continuation run, you need to edit the UM script called SUBMIT in umui_jobs/<runid> directory on PUMA and change

TYPE=NRUN to TYPE=CRUN

If your initial run was a compile and run job in one job then you need also to change to

STEP=4

in the SUBMIT script as well.

Then resubmit the run as you did for the initial run. The run should continue from where the initial run finished and, if you were running for more than 2 months, then each of the remaining chunks should submit themselves automatically without further intervention.

Regards,
Ros.

Ros,

Thanks - I'll give that a go. It turns out I have more experience with this than I quite realised, in that I am fairly familiar with the UM scripts but very new to NEMO. I find it fiddly that an NRUN has to be manually turned into a CRUN to resubmit it, and for version 4.5 I ended up writing a script mod so that an NRUN would turn itself into a CRUN on resubmission rather than refusing to resubmit. I am attaching that script mod to this ticket. Maybe it could be adapted for later versions?

The ability to switch a job to a CRUN is in the UMUI at later versions.

Alan's attached script has been saved in $HOME/umui_jobs/script_mods on PUMA.
