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.

CMCC-1 - Scalability with MPI-OPENMP

Motivation: Improve NEMO scalability.
Status : continuation of 2014 dev CMCC-1
Main tasks : extension of the hybrid OpenMP/MPI approach to the entire code
Science Reviewer:
System Reviewer:
Deadline: December 2015
Priority: MEDIUM
Depends on:
Principal Investigator : S. Mocavero

CMCC-2 - Scalability with mapping strategies

Motivation: Improve NEMO scalability
Status : New
Main tasks : use of suitable mapping strategies to optimize the code performance
Science Reviewer:
System Reviewer:
Deadline: December 2014
Priority: MEDIUM
Depends on:
Principal Investigator : I. Epicoco

CMCC-3 - Performance analysis of parallel IO

Motivation: Improve NEMO IO scalability
Status : New
Main tasks : performance comparison between XIOS and other parallel I/O approaches such as MPI-IO and Parallel NetCDF.
Science Reviewer:
System Reviewer:
Deadline: June 2015
Priority: HIGH
Depends on: XIOS
Principal Investigator : S. Mocavero

CMCC-4 - Evaluation of dynamic allocation strategy

Motivation: Evaluate the performances introduced by the work space allocation (wrk_alloc / wrk_dealloc) instead of the automatic allocation
Status : new
Main tasks : compare the wkr_alloc / wrk_dealloc version with the automatic allocation
Science Reviewer:
System Reviewer:
Deadline: Decemper 2014
Priority: LOW
Depends on:
Principal Investigator : I. Epicoco

CMCC-5 - ensemble generation suite

Motivation: to generate ensemble members by spanning uncertainties in the atmospheric forcing and the model parameterizations
Status : continuation
Main tasks : The ensemble generation suite consists of three components, switchable either simultaneously or individually. The components perturb i) the atmospheric forcing, provided as input the atmospheric parameter standard deviation and possibly, the temporal decorrelation scale of the perturbations. These perturbations are correlated in time and space, and the user can choose the correlation scales; ii) the model tendencies within a number of user-selected tendencies (e.g. tracer diffusion, solar penetration, etc.). Perturbations are collinear to the tendencies and the user can choose the decorrelation scales of the perturbations; iii) selected namelist parameters, provided a user-compiled range of values for the individual parameters (e.g. vertical eddy viscosity, etc.).
