Context and objectives

The NEMO Developer's Committee is responsible for the organisation of an update of NEMO Development Strategy document published in 2014. Objective is to produce a new version of this document in June 2017.
Agenda has been approved 28 June 2016:

  • July to September 2016:
    • Experts identified in the table above to build the preliminary list of questions to discuss (on a wiki page, to be created), and the list of possible contributors
  • September 2016:
    • Comments and additions of these documents by Developer's Committee members
    • Developer's Committee to suggest list of participants for the meeting
  • October 2016: !Agenda and announcement of the meeting in March 2017. (See attached document from J. Le Sommer and M. Bell at the bottom of the page)
  • December 2016: During Developer's Committe meeting, finalize organisation of Development Strategy meeting
  • January to March 2017:Experts listed in table above to draft their chapter
  • March 2017: Development Strategy meeting
  • March to June 2017: Writing and release of new version of Development Strategy document and endorsment from Steering Committee
  • June 2017: Publication of updated NEMO Development Strategy document

Work has been distributed by chapters of the document:

Expert(s) to lead discussions and writing of the chapter
Chapter 1 - Elements of long-term strategy as defined in 2017 → 2022 C. Lévy and writing group
Chapter 2 - Target applications for NEMO by 2022. Julien Le Sommer
Chapter 3 - HPC performance constraints HPC working group
Chapter 4 - Future evolutions of NEMO ocean kernel. Mike Bell
Chapter 5 – Ocean dynamics component of NEMO (including state of the art on subgridscale parametrisations and on tides, see above) Julien Le Sommer
Chapter 6 – Toward locally higher effective resolution: AGRIF Jérôme Chanut
Chapter 7 - The assimilation and ensemble component of NEMO Pierre-Antoine Bouttier and Dan Lea
Chapter 8 - The ice components of NEMO Ed Blockley and Martin Vancoppennolle
Chapter 9 -Air sea interface and surface boundary layer physics Laurent Brodeau
Chapter 10 - The biogeochemical component of NEMO: TOP and its interface Olivier Aumont and Tomas Lovato
Chapter 11 - NEMO validation and range of user support (including user interface to build configurations, and Configuration Manager) Andrew Coward

This page includes a first draft, written by the experts listed above, indentifes for each chapter the points of concensus and the list of subjects to be discussed (with associated list of questions).


Template as starting point for each chapter below:

List of points for which concensus is reached:
(associated actions to schedule, if relevant)

List of subjects in discussion (no concensus yet)
and associated question to lead the discussions next March


Chapter 1 - Elements of long-term strategy as defined in 2017 → 2022 - C. Lévy and writing group

Chapter 2 - Target applications for NEMO by 2022. - Julien Le Sommer

Chapter 3 - HPC performance constraints - HPC Working Group

Chapter 4 - Future evolutions of NEMO ocean kernel. - Mike Bell

Chapter 5 – Ocean dynamics component of NEMO (including state of the art on subgridscale parametrisations and on tides, see above) - Julien Le Sommer

Chapter 6 – Toward locally higher effective resolution: AGRIF - Jérôme Chanut

Chapter 7 - The assimilation and ensemble component of NEMO - Pierre-Antoine Bouttier and Dan Lea

Chapter 8 - The ice components of NEMO - Ed Blockley and Martin Vancoppennolle

Chapter 9 - Air sea interface and surface boundary layer physics - Laurent Brodeau, Gurvan Madec

Please see here!!! Can't cope with this wiki syntax…

Chapter 10 - The biogeochemical component of NEMO: TOP and its interface - Olivier Aumont and Tomas Lovato

  • Establish the production of scientifically validated simulations (e.g., validation suite and data repository) to enable the long term assessment of model developments and improvements.
  • The medium term development of TOP should lead to a general interface for ocean tracers

capable to solve all key processes (BC treatment, light in the water column, sinking etc), independently from a specific biogeochemical model. This will translate into a seamless interface where only the core equations of biogeochemical models will be needed to couple with NEMO.

  • The uprising complexity of biogeochemical models will require the revision of current HPC approach and the adoption of novel techniques to cope with the increasing computational efforts. In particular, the exploitation of accelerators and GPUs might become a key resource to deal with computational constraints.
