UKESM Simulation will not restart.

Reported by: aschurer Owned by: um_support
Component: UM Model Keywords:
Cc: Platform: Monsoon2
UM Version: 11.0


I am struggling to restart a UKESM simulation u-bf095 on MONSOON.
After an initial 50 years simulation I restarted it to run for an additional 20 years. This completed without any errors.
I now wish to run it for another 50 years.
Consequently I set the RUNLEN=70,0,0,0,0,0
and entered on the command line:
rose suite-run —restart
The model returned an error at the coupled stage:

[FAIL] Unable to find top restart files for this cycle. Must either have one, or as many as there are nemo processors (109)
[FAIL] Found 108 iceberg restart files
[FAIL] run_model # return-code=144
2019-08-19T19:56:10Z CRITICAL - failed/EXIT

I've checked and I have got 108 restart files in this directory:

Please can you advise why this model simulation is not restarting and why it is looking for 109 restart files?

Thanks in advance,

Hi Andrew,

The error message is slightly wrong; it should say it has found 109 restart files but needs either 1 or 108. (The variable substitutions are the wrong way round in the script.)

I suspect the problem is because you have 108 individual restart_trc files plus the rebuilt one giving a total of 109.

Hi Ros,
Thanks for you reply.
Does this mean that I need to delete some restart files?

And if so - should I delete the individual restarts files:

or the rebuilt one:

I decided to re-submit this manually using the restart files.
This solved the problem.
Many thanks,
