Hi CMS, I am trying to run the UKESM1 historical suite (u-bc613/archer2) which has been ported to Archer2 and updated since the Archer2 o/s upgrade. My copy is u-cy797.
It runs fine for the first cycle, but fails on the second, with an error in the ‘coupled’ task:
UnboundLocalError: local variable ‘checkpoint_date’ referenced before assignment.
I noticed that Ros suggested in reference to a different suite that having a cycling frequency of at least 1 month might get around this error, but I tried a 2 month run with 1 month cycling and this didn’t solve it.
The only significant change i’ve made to u-bc613 in my version is to add the following line to /site/archer2.rc (as suggested in this thread):
This addition fixed an error i had previously, where the postproc_nemo task failed with insufficient memory.
Do you have any advice on solving this issue with cycling?
