CMCC.1 Scalability Optimizati

Motivation: The optimization of NEMO scalability.
Status: to be started in January 2012
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.
* Introduction of a new parallel approach based on the functional parallelism for the tracers and the momentum equations. The parallelism will be based on spreading: (i) the computation of the tracers and momentum equations and (ii) the computation of the advection, Coriolis, pressure gradient and lateral diffusion terms.
* Implementation of a new hybrid parallel approach for exploiting the 3D domain decomposition (MPI on the horizontal domain, OpenMP on the vertical levels)

CMCC.1 Modification of masks

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

CMCC.1 Direct interface with data assimilation

Motivation: Interface with data assimilation systems
Status: to be started in January 2012
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: 2012-2013
Priority: Medium
Principal investigator: Srdjan Dobricic

CMCC.1 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: to be started in January 2012
Main tasks: Add a routine that will apply the divergence filter in addition to the horizontal diffusion of the velocity.
