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.

Shared Actions

Shared Actions contains the workplan's core: the development priorities for all NEMO consortium's institutions which are expected to be directly related to the long term goals.

            #2017 AGRIF-03_jchanut-TOOLS jchanut 2018 release-4.0 Revised coordinates and bathymetry creation steps (including ghost cells number extension). 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.
            #2018 AGRIF-04_jchanut-TSTEPPING jchanut 2018 WP Status in June 2018: Not started yet. Likely better to postpone this task till first RK3 time stepping draft is available (TBD).

            #2019 ENHANCE-03_jchanut-ZTILDE jchanut 2018 WP Status in June 2018: Enhanced z tilde implementation is available in NEMO 3_6 stable release. Possible transfer in trunk in 2018 (TBD).
            #1911 ENHANCE-04(2017WP) — MLF and RK3 time stepping gm 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.

            #1943 HPC-02(2017WP)_Francesca Development of the NEMO hybrid parallel version based on MPI/OpenMP francesca 2018 WP The improvement of the hybrid coarse-grained approach (about 7% when the MPI scalability limit is reached) is not enough to justify the refactoring of the code. 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.
            #2010 HPC-03_Mocavero_globcomm mocavero 2018 release-4.0 The analysis on global communications has been updated on the new trunk and the development branch has been created.

            #2038 VALID-05_clevy_AGRIF clevy 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 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 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.
