LOCEAN .1 - MPP evolution (continuation)

Motivation: Improve the mpp behaviour of NEMO by playing with width of the overlap area, the number of communication,
Status : We are now using 1 point overlap area. Possibility to use more exists but is not compatible with the North Fold condition
Main tasks :
(1)switch to a 2 points with overlap area
(2)suppress useless communication (there should be only 2 for the internal mode)
Science Reviewer:
System Reviewer:
Deadline:
Priority: high
Depends on :choice of dynamic/static allocation mode
Principal Investigator : Rachid Benshila (rachid.benshila@…)

LOCEAN .2 - Coupled interface (end)

Motivation: The current coupled surface module only work with LIM2. Its functionality should be extended to the cases where sea ice is not used (for example with region coupled configuration), and where a multi category sea-ice component is used (LIM3 or CICE).
Status : Preliminary work has been done for CICE
Main tasks :
(1) documentation of the coupled surface module
(2) coupling with multi-categories ice model (coll. UKMO)
Science Reviewer:
System Reviewer:
Deadline:
Priority:
Depends on: collaboration with UKMO
Principal Investigator : Sebastien Masson (smasson@…)

LOCEAN .3 - Merge TRA-TRP (end)

Motivation: Merge of active and passive tracer advection/diffusion modules to avoid duplication of almost identical modules
Status : The merge has been done for transport routines, using a switch to avoid the suppression of T and S array at this time
Main tasks :
(1) validate the compatibility of vvl with biogeochemistry
(2) suppress T and S array to switch to 4d arrays
(3) apply the merge for OBC, BDY, AGRIF

System Reviewer:
Deadline:
Priority: high
Depends on:
Principal Investigator : Christian Ethé (Christian.Ethe@…)

LOCEAN .4 - reference manuels (continuation)

Motivation: paper documentation a never-ending story (dixit G. Madec)
Status :
Main tasks :
(1) Create the TRP documentation using Latex (similar to the NEMO ocean engine documentation)
(2) review of the written documentation (NOCS team)
Science Reviewer:
System Reviewer:
Deadline:
Priority:
Depends on: LOCEAN.3
Principal Investigator : Christian Ethé (Christian.Ethe@…)

LOCEAN .5 - updating OBC

Motivation: OBC needs to be revisited to work with explicit free surface. It could be the opportunity to rewrite the whole routine, using fldread for OBC inputs, and a generalized treatment for all boundaries, to be able to deal with different boundaries schemes.
Status : Two way to handle OBC are coexisting in the system. in addition, the way to handle input oceanic data is quiet painful
Main tasks :
(1) write specifications
(2) write input routine based on fldread
(3) write a generic routine
Science Reviewer:
System Reviewer:
Deadline: spring 2012
Priority:
Depends on: successful shared work with Mercator and UKMO
Principal Investigator : Rachid Benshila (rachid.benshila@…)

LOCEAN .6 - update the IOSERVER

Priority:
Depends on: work done on new IOserver at IPSL
Principal Investigator : Sebastien Masson (smasson@…)

LOCEAN .7 - rewrite NVTK

Motivation: the test suite has to be totally revisited for portability and an easy addition of new tests .
Status : The compilation system has been rewritten but doesn't include tests
Main tasks :

Priority:
Depends on: feedback from others members of the team

This is part of the IsENES EU project.
Status : ORCA2-LIM2 configuration (bathy, physics) has been updated, and Standard output for IPCC runs using IOM(v3.2). An environment has been developed to run long forced and coupled experiments together with the creation of standard control plots. Simulations have been performed (reference CORE2 normal year and interannual simulations )
Main tasks :
