ticket : #1347

Branch : TBC


Description

Two changes are planned to the restart functionality within NEMO/LIM:

  1. to allow users to exactly specify a list of timesteps on which the model will write out restart files. This will involve modification of OPA only
  1. to allow the user to specify the directory where restarts will be written to as is done in the SBC/fldread module. This will require modification of LIM2 & LIM3 as well as OPA

Testing

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

NVTK Tested'''YES'''
Other model configurations'''NO'''
Processor configurations tested[ Enter processor configs tested here ]
If adding new functionality please confirm that the
New code doesn't change results when it is switched off
and ''works'' when switched on
'''YES'''

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

'Please add further summary details here'

  • All SETTE tests passed when functionality is turned off.
  • ORCA2LIM3, ORCA2LIMPIS and ORCA2OFFPIS tested reading and writing restart files to other directories and with a list times to output restart files.

Bit Comparability

Does this change preserve answers in your tested standard configurations (to the last bit) ?'''YES '''
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?'''YES
Is this change expected to preserve all diagnostics?
,,''Preserving answers in model runs does not necessarily imply preserved diagnostics. ''
'''YES

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

  • Which routine(s) are causing the difference?
  • Why the changes are not protected by a logical switch or new section-version
  • 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……..

System Changes

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

If any of these apply, please document the changes required here……. Added cn_ocerst_indir, cn_ocerst_outdir, ln_rst


Resources

''Please ''summarize'' any changes in runtime or memory use caused by this change……'' Minimal changes


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……….
