New URL for NEMO forge!   http://forge.nemo-ocean.eu

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-7 AGRIF Not Funded

CMCC.1 Scalability Optimization

Motivation: Improve NEMO scalability.
Status: to be started
Main tasks:
* Introduction of a new software layer in the NEMO stack software exploiting numerical optimized and parallel libraries such as pBLAS, ScaLAPACK and PETSc.
* Continuation of the implementation of hybrid parallel approach based on the functional parallelism for the tracers, momentum equations and 3D domain decomposition.
* Test performances of XIOS on CMCC architectures

Deadline: 2013
Priority: Medium
Principal investigator: Italo Epicoco

CMCC.2 Modification of masks

Motivation: Expand the modification of masks to the EEN scheme
Status: started in 2012, continued in 2013
Main tasks: Evaluate the impact of fmask on the EEN scheme and eventually make modifications.
Science Reviewer: Gurvan Madec
Deadline: 2013
Priority: High
Principal investigator: Srdjan Dobricic

CMCC.3 Direct interface with data assimilation

Motivation: Interface with data assimilation systems
Status: to be started
Main tasks: Develop software interface that will avoid the writing to the disk, provide the possibility to use a different domain decomposition in Nemo and the data assimilation, reduce the memory usage of Nemo when it is inactive.
Science Reviewer: MetOffice
Deadline: 2013
Priority: Medium
Principal investigator: Srdjan Dobricic

CMCC.4 Divergence damping filter operator

Motivation: Additional diffusion on only the divergent component of the velocity could reduce the numerical noise at the high model topography (step topography, deep convection, etc.).
Status: continuation of 2012 activity. Tested but not documented
Main tasks: Add a routine that will apply the divergence filter in addition to the horizontal diffusion of the velocity.

CMCC.5 Vertical stability of increment fields

Motivation: Modify the increment field in order to reduce the vertical instabilities.
Status: to be started
Main tasks: Modify the ASM code to add the diagnostics of the vertical stability and the modificatyions to the increment fields.
System Reviewer:
Science Reviewer: Met Office
Deadline: 2013
Priority: Medium
Principal investigator: Srdjan Dobricic

CMCC.6 Surface and lateral boundary conditions for tracers

Motivation: Add generic interfaces for surface and lateral boundary conditions for BGC tracers (river input, atmospheric deposition, open boundary conditions).
Status: started in 2012, first implementation waiting for the final choice of BDY
Main tasks: Port the interface used for transport routines to the surface and boundary condition routines currently used for T and S.
System Reviewer: C. Ethe'
Science Reviewer: C. Ethe', ??
Deadline: 2013
Priority: High
Principal investigator: Marcello Vichi

CMCC.7 Testing of AGRIF: scalability and usage with biogeochemical variables

Motivation: evaluate AGRIF performances in realistic domains and utilization with the BFM
Status: this activity has not been funded and will not be undertaken for this year
Main tasks: check performances of AGRIF with an Atlantic refinement; assess the compatibility with BFM variables and the related computational overhead
