How to retrieve NEMO/GELATO code from the opensource git server and how to compile the model
- Access to the CNRM open-source server
https://opensource.cnrm-game-meteo.fr/ You need to subscribe to the server by clicking on register (right left). When you have registered, ask an admisnistrator for the access to the NEMO-CM project (via a mail to the administrators youcef.amar@meteo.fr, matthieu.chevallier@meteo.fr, aurore.voldoire@meteo.fr) and send us your ssh key for the machine where you want to access to the git server.
- Retrieve the code
git clone --recursive ssh://reader081@git.cnrm-game-meteo.fr/git/NEMO-CM.git . This will create a local git repositery in a directory called NEMO-CM that includes the NEMO code and the GELATO code.
- Code compilation
To compile in NEMOGCM/CONFIG
compilnemo -n ORCA1_GLT_CPL -m CM6b2_cpl_xios1442-shuffle -j 40 CM6b2_cpl_xios1442-shuffle is a compilation environment described in NEMOGCM/ARCH/CNRM/arch-CM6b2_cpl_xios1442-shuffle.fcm. If you need to use a new compiler, a new xios version and/or machine, the best is to create a new arch file and to use its name in the compilation command.
If you want to compile a specific version of the code, you need to checkout on GELATO and NEMO respective depository.
For instance if you want to create a binary with commit 403faa1e1876a36ce7c6dd23 for NEMO and 37be737c236c8d0 for GELATO, do :
cd NEMO-CM
git checkout 403faa1e1876a36ce7c6dd23
cd NEMOGCM/NEMO/GLT_SRC
git checkout 37be737c236c8d0
