Branch :


Tidal harmonic package


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

NVTK Tested'''YES'''
Other model configurations'''YES'''
Processor configurations tested[ 1*1,4*4,2*8 ]
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'

Tests done on IBM power 6:

  • reproductiblity: ORCA2_LIM with time splitting and tidal potential forcing: compare 2*8 and 4*4 configurations: results are identical ( for 75 time steps, with key_mpp_rep )
  • restartability: The restart capability is not implemented.

Tests on theoric ssh: I impose a sea surface heigh in input to the diagnostic with a known decomposition in harmonic and the output is the exact solution.

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. ''

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…….


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……….

Tidal Harmonic analyse on ORCA2_LIM

Configuration: ORCA2_LIM standard + time splitting + tidal potential forcing Experience:

  • 1 year of simulation

We compare to TPXO 7.1 ATLAS

We can see the figure for the tidal composante M2 (real and imaginary part).
