3_6_STABLE final sprint

Sequence of actions for each branch

For each development branch to be committed in the trunk, following steps have been fullfilled:

  • Branch has been validated regarding its new features in appropriate way, and if possible tested on a CMIP6 like configuration or at least on the ORCA2_LIM3 reference configuration (using vvl)
  • SETTE tests passed: run sette.sh and sette_xios.sh
  • Reviewer has approved

Since the timing is tight and we need to check each step, changes in the trunk will be made sequentially, and tested at each step. For a given branch to be commited, sequnce should be:

  • Update the branch to head of trunk
  • Final test of the branch
  • merge branch with trunk: this should include documentation in reference manual….
  • SETTE test on new trunk
  • Commit new trunk
  • Send a mail to nemo_st to say you've finished (in order for the next branch to be able to start, see proposed agenda below)

3_6_STABLE release annoucement (draft)

Up to now, the stable NEMO release was 3_4_STABLE.
From now on a new 3_6_STABLE release is available, cf. https://forge.ipsl.jussieu.fr/nemo/browser/branches/2015/nemo_3_6_STABLE.

This release will be used by all CMIP6 experiments using NEMO (CERFACS, CMCC, EC_EARTH, Hadley Centre, IPSL)
It includes all developments from 3_4_STABLE, i.e. 3_5, 3_6_beta, including the new XIOS IO system and some new features.

Main new features (for details, see http://www.nemo-ocean.eu/History-and-Release-notes):
    •    Coupled interface for next IPCC requirements (multi category sea-ice, calving and iceberg module)
    •    Runoff improved and SBC with BGC
    •    Solar flux filtering at daily frequency to force BGC component
    •    Major evolution of LIM sea-ice model (including LIM3 in mono category, i.e. similar to LIM2)
    •    On line coarsening of ocean I/O
    •    Ocean and ice allowed to be explicitly coupled through OASIS, using StandAlone Surface module)
    •    First steps of wave coupling
    •    MPP optimisation
    •    XIOS new IO system
    •    Standard Fox Kemper parametrisation
    •    Atmospheric forcing at land-ocean interface
    •    Open boundaries: completion of BDY/OBC merge
    •    Solved 2 time stepping issues
    •    Faster split-explicit time stepping, Z-tilde ALE coordinates, implicit bottom friction
    •    First version of Configuration Manager
    •    Standalone OBS component and improvements in OBS&ASM
    •    
Features becoming obsolete:
    •    LIM2
Quick start guide available here: http://www.nemo-ocean.eu/Using-NEMO/User-Guides/Basics/NEMO-Quick-Start-Guide
Validation:
3_6_STABLE has been validated as usual :so-called SETTE tests (restartability and reproducibility an each of the reference configurations (http://www.nemo-ocean.eu/Using-NEMO/Configurations) and appropriate validations of all new developments. Details on validation can be found here: http://www.nemo-ocean.eu/Developing-with-NEMO/Validation/nemo-v3.6_STABLE-Validation

WARNINGS: add here what remains to be tested, or still unsure, in this first revision of 3_6_STABLE, if needed

Associated branches: to be done

A few associated development branches will remain aside, at least until full validation. THose developement branches listed below will be kept up to date with 3_6_STABLE. A project needing one or more of these branches will have to

  1. Extract 3_6_STABLE
  2. Merge the needed development branch with 3_6_STABLE locally (see documentation here, to be done)
