Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

Summary

Action HPC-9_Gurvan : ZDF restructuration with reduced number of lbc_lnk call
PI(S) Gurvan Madec

Digest

Restructuration of all vertical physics packages (ZDF) in order to reduce the number of communication and suppress most (if not all) the key_zdf...

  1. remove avmu, avmv, keep only avm and use an average in the dynzdf_imp (_exp) modules (save mpp comm)
  2. Define tau_i, tau_j, the surface ocean stress at t-point, and remove utau, vtau (stress defined at u- and v-point) to remove the communication phase on utau and vtau.
    This require to adapt the dynzdf modules.
  3. create the zdf manager that encapsulate all modules that modify avm and avt. ==>> only one communication phase on those fields at the end of the ZDF manager instead of one by ZDF modules.
    In the process, we also remove all the key_zdf... replaced by namelist variables.
  4. simplification: introduce a generic routine to perform the inversion of a tri-diagonal matrix and use it in implicit vertical diffusion (DYN and TRA),
    in TKE and GLS, and in 4th order compact scheme (TRA and DYN).

Abstract

This section should be completed before starting to develop the code, in order to find agreement on the method beforehand.

Error: Failed to load processor TracForm
No macro or processor named 'TracForm' found

Once the PI has completed this section, he should send a mail to the previewer(s) asking them to preview the work within two weeks.

Preview

Since the preview step must be completed before the PI starts the coding, the previewer(s) answers are expected to be completed within the two weeks after the PI has sent his request.
For each question, an iterative process should take place between PI and previewer(s) in order to reach a "YES" answer for each of the following questions.

Error: Failed to load processor TracForm
No macro or processor named 'TracForm' found

Once all "YES" have been reached, the PI can start the development into his development branch.

Tests

Once the development is done, the PI should complete this section below and ask the reviewers to start their review in the lower section.

Error: Failed to load processor TracForm
No macro or processor named 'TracForm' found

Review

A successful review is needed to schedule the merge of this development into the future NEMO release during next Merge Party (usually in November).

Error: Failed to load processor TracForm
No macro or processor named 'TracForm' found

Once review is successful, the development must be scheduled for merge during next Merge Party Meeting.
