2010: from merge party to 3_3 release
Last edited Timestamp?
This page is intended to faciltate the work of the next weeks, i.e. beween the merge party and the release of 3_3. Feel free to edit it to add your informations comments, suggestions....
19 october 2010: branch nemo_v3_3_beta created
After the merge party, the branch with all developments of the year is build:
This beta version is available using :
svn co https://forge.ipsl.jussieu.fr/nemo/svn/branches/nemo_v3_3_beta/NEMOGCM (read only)
svn+ssh://"your_login"@forge.ipsl.jussieu.fr/ipsl/forge/projets/nemo/svn/branches/nemo_v3_3_beta/NEMOGCM (read/write).
List of tests done and results:
Add here test description (Branch nemo_v3_3_beta, Revision2298 (now) , configuration, computer, restartability, ...)
Description | Revision no | Configuration | Computer | Perf. memory | Perf. CPU | Restartability | Others |
List of problems, solutions…
Before releasing it to developper's for beta testing, the following weaknesses should be solved: (please update the informations)
Date | Revision no | Problem description | To be solved by: | State | Date | Version |
with AGRIF | LOCEAN and LJK | Compilation now OK but not execution | ||||
new EVP rheology got lost during the merge | MERCATOR | routines and namelist commited | 27 Oct 2010 | 2320 |
new EVP rheology got lost during the merge ( Mercator)
20 Oct 2010: routines are ok, tests are runnings. 27 Oct 2010: routines and namelist commited ( rev 2320 )
suppress tke_old(to be done at LOCEAN)
22 Oct 2010: DONE, ticket #742
add LibIGCM as external (tbd at LOCEAN)
choose between key_mpp_rep1 and key_mpp_rep2, rename it key_mpp_rep and clean the code (tbd at LOCEAN)
22 Oct 2010: DONE, ticket #743
add surface pressure forcing (tbd at Mercator)
correct input files (tbd at LOCEAN)
in ORCA2_LIM tar file, suppress duplicated files, rename chlorophyll one to fit the namelist, add a sample of observation file
Pb while running the code
bottom condition for GLS should be checked (Mercator)
20 Oct 2010: routines are ok, tests are runnings. 25 Oct 2010: modification is under svn ( rev 2309, see zdfbfr.F90 ).
time splitting and VVL (UKMO and LOCEAN)
code explode after 2 time steps...
Rules to follow:
- all correction to the developments done in 2010 should be done on the beta branch, not on the original branch
- contribution to the documentation should be send directly to Gurvan, with Rachid on copy
- between now end the tag nemo_v3_2_2 correction of bugs have to be done on both the trunk and the beta branch when the bugs are on the two version
Schedule:
- diffusion to the developers at the beginning of november
- tag a last version stable of nemo_v_3_2 (nemo_v3_2_2) at the end of december
- put back the beta version on the trunk just after
- tag and release nemo_v3_3
- delete the developments branches for 2010 (if they went back to the new version off course)
Announcement of 3_3 to users (To be improved, in particular by adding the ticket number to find more details on the development)
Main features:
Scientific and numeric Developments
- Lateral ocean physics: Griffies operator added
- Vertical mixing scheme Generic Length Scale (GLS) added
- Changes in bottom boundary layer (bbl)
- Develop mixed laplacian-bilaplacian diffusion
- Time stepping : modified Leap-Frog Asselin filter (MLF) implemented
- Sea-ice: the Elasto-Visco Plastic (EVP) rheology has been added in LIM2 (the oldest version of the sea-ice component)
- Atmospheric pressure forcing added
- Change formulation of the fluxes between ocean, ice and atmosphere : an exchange of water (mass exchange) is now explicitly associated with an exchange of heat and salt content.
- New implementation of river runoffs
- Diurnal cycle added
- Coupling interface for WRF atmospheric model added
- Development of data assimilation modules OBS and ASM
- Linear-tangent and Adjoint component (TAM) added, phased on tag 3.0
Computing Developments
- Performance improvements in parallel (MPI)
- Reorganisation in tracers transport computation (merge of TRA and TRC modules)
- Biogeochemistry offline (TOP) reorganised (avoid routines dupplication between on-line and offline use of TOP)
- "On the fly" interpolation added for input (forcing) files
- Use of FCM (Flexible Configuration Manager) to build the chosen configuration, generate Makefile and run it to produce the executable)
Documentation
- Major updates in the reference manual, which is now more in phase with the code
- Smaller updates on the web pages documentation (but FAQ page more actie from now on)
- Detailed documentation and results of the reference configuration ORCA2_LIM forced by CORE II
Major changes
- In MPP, number of processors is now done by cpp keys: -Dkey_nproci=2 Dkey_nprocj=2 for instance'
- FCM use changes the diectory hierarchy and the way to set up configuration and create executable
