20 nov. 2015: discussion on 2015 workplan proposal within the NEMO community

If you’re interested in the perspectives of NEMO development, you are welcome to join the videoconference :
Thursday 20 november at 2:30 Paris time.
The NEMO System team members will be connected to discuss and answer your questions on the 2015 workplan proposal in order to prepare the meeting of NEMO Developer's Committee taking place 4-5 december.
This workplan proposal is available here: https://forge.ipsl.jussieu.fr/nemo/wiki/2015WP
The videoconference will stay open from 2:30 to 4:30.
If you intend to join, please send a mail to System Team for connection information.

Introduction (Claire Lévy):

Objective of the meeting: discuss 2015 workplan.

NEMO System Team develops the NEMO reference through a yearly workplan, i.e. a list of actions, with PIs..., and working groups.
Actions listed in workplan = code developed, whereas Working Groups discuss to make scientific and/or technical choices and set up appropriate development actions.
There is only 1 NEMO reference, so that there must be some coherency in all this.

At this point, discussions took place within NEMO System Team to elaborate the proposal.
Genral context:

  • we now have the Development Strategy” document, finalised last june, identifying for mid-term what we agreeded on, and what remains in discussion
  • 2015 will be a “special year”, because we needed a STABLE release in May for CMIP6

Objective of this meeting: get the inputs and comments from the NEMO community on the 2015 workplan proposal. For now, it is on the wiki, in 2 parts:

  • the so called “Shared Actions”, core of the proposal, as the 2015 contribution to the evolution of NEMO defined in the Development Strategy, to be achieve by the NEMO System Team (experts), i.e. the “minimum 1 man-year” per institution of the Consortium
  • the “per institution” pages: additional work, with additional manpower, to achieve some developments of specific interest for an institution of the consortium

As first overview, the Shared actions pages lists 7 paragraphs:

  • AGRIF
  • HPC
  • Configuration Manager
  • System Simplification
  • Wave coupling
  • NEMO robustness
  • Publications in GMD

Open questions are:

  • Do you find this list appropriate regarding bot general strategy and the needs of your projects?
  • Do you find this list relaistic (i.e. feasible with the known manpower)?

Discussion

  • What about the developments, updates... in the coupling interface, needed for CMIP6? They are not listed in 2015 workplan[Uwe Fladrich, for EC-EARTH]

Those are expected to be finalised now (i.e. for the Merge Party in december 2014), or at the latest very beginning of 2015. Planning is to have the nemo_v3.6_STABLE release ready and fully validated for CMIP6 mid-2015.

  • Could we have some details on HPC actions in 2015? What about HPC-2 action (MERCATOR - M. Chekki)? What about OpenMP? Are there some plans to look in details at relative performance of routines in NEMO?[Kim Serradell Maronda, BSC]
  1. Chekki will be PI of an action on HPC still to be defined.
    Concerning OpenMP, a first development branch exists, implementing OpenMP in the GYRE reference configuration. Work is planned to generalise it for NEMO (HPC-1 - CMCC-S. Mocavero).
    BSC is more then welcome to contribute (to be discussed between BSC and S. Masson, leader of HPC working group)
