2018 Workplan

NEMO is a shared, sustainable, and state-of-the-art software for research and operational oceanography. Its development is defined in a yearly workplan.
The yearly work plan is based on the NEMO Development Strategy Version 2 : 2018-2022.

The next 2 sections describe the 2018 workplan.

A new AGRIF configuration has been successfully set up with this version. Need to revise create_restart step and potentially add a create_restart_ice to make the tool fully functionnal with NEMO4.0.

            #1911 ENHANCE-04(2017WP) — MLF and RK3 time stepping gm high 2018 release-4.0 strategy of implementation and design of the targeted code ~OK. Two big steps: (1) transform the leap-frog scheme (MLF) to be consistent with a 2-level time-stepping environment ; (2) introduce the RK3 scheme. Step 1 expected to be ready for the 2018 merge party whereas Step (2) is not assured at that time.

A final test by combining a tessellated approach with OpenMP will be performed and the ticket will be closed by the end of this year.

            #2038 VALID-05_clevy_AGRIF clevy high 2018 release-4.0 This validation action is only partly successful: implementation of this North Atlantic configuration with 2 embedded AGRIF zooms works fine with the first zoom only: with the second (higher resolution) zoom the configuration crashes. Is it very likely that the errors come from the configuration (e.g. from me) since the new AGRIF_DEMO reference configuration with sea ice and 3 zooms works fine. Work to be continued second semester 2018.
            #2030 VALID-06_storkey_global validation of proto-NEMO 4.0 release in ORCA1, ORCA025 and ORCA12 davestorkey high 2018 release-4.0 I have completed 30-year CORE2-forced integrations for ORCA1 and ORCA025 based on rev 9490 of the dev_merge_2017 branch. There are significant science differences between these configurations and our standard NEMO 3.6 configurations (different sea ice model, currently no internal wave mixing in NEMO 4 configurations), so one would expect different results, but the results look sensible and the differences are where you would expect them given the science differences.
            #2028 VALID-07_odea-AMM deazer high 2018 release-4.0 The AMM15 configuration was tested initially with revision 9356. The configuration ran ok for 6 months but had a problem with the boundary conditions using the zerograd option. With this removed the model has been run successfully for 2 years with sensible looking model fields. The model was also run in WAD successfully for 2 year integration, and some further modification to stop SBC fluxes in dry areas lead to sensible fields. It was not reproducible at this revision in terms of different processor decompositions. Currently testing revision before the code was reorganized as rose suites need considerable updating to work wit the reorganized code. Revision 9490 is being integrated (currently 4 months) as before. It is still not perfectly reproducible across different processor decompositions but the differences are much smaller then at revision 9356.
