ticket : #1399

Branch : dev_r4650_UKMO13_CICE_changes_take2


Changes to the CICE interface to allow NEMO to run with CICE5.

Variable names in the CICE5 model and included in NEMO via a USE statement are different to those in CICE4. For this reason a new key (key_cice5) is introduced to control whether CICE4 or CICE5 is used.


Testing could consider (where appropriate) other configurations in addition to NVTK].

SETTE Tested'''YES
Other model configurations'''YES
Processor configurations tested Standard SETTE configs
If adding new functionality please confirm that the
New code doesn't change results when it is switched off
and ''works'' when switched on

(Answering UNSURE is likely to generate further questions from reviewers.)

'Please add further summary details here'

Bit Comparability

Does this change preserve answers in your tested standard configurations (to the last bit) ?'''YES ! ( as these don't use CICE)
Does this change bit compare across various processor configurations. (1xM, Nx1 and MxN are recommended)'''YES'''
Is this change expected to preserve answers in all possible model configurations?'''NO'''
Is this change expected to preserve all diagnostics?
,,''Preserving answers in model runs does not necessarily imply preserved diagnostics. ''

If you answered '''NO''' to any of the above, please provide further details:

  • Which routine(s) are causing the difference? - The changes in answers are from the updated CICE model rather than NEMO.
  • Why the changes are not protected by a logical switch or new section-version - CICE version is switchable.
  • What is needed to achieve regression with the previous model release (e.g. a regression branch, hand-edits etc). If this is not possible, explain why not.
  • What do you expect to see occur in the test harness jobs?
  • Which diagnostics have you altered and why have they changed?Please add details here……..

Changes occur in ice area and feed back onto SST/surface fluxes/currents etc.

System Changes

Does your change alter namelists?'''NO '''
Does your change require a change in compiler options?'''YES '''

If any of these apply, please document the changes required here……. To work with CICE5 model the code must be compiled with key_CICE5. To work with CICE4 model the code must be compiled with key_CICE (this has not changed).


Little change

IPR issues

Has the code been wholly (100%) produced by NEMO developers staff working exclusively on NEMO?'''YES '''

If No:

  • Identify the collaboration agreement details
  • Ensure the code routine header is in accordance with the agreement, (Copyright/Redistribution? etc).Add further details here if required……….
