Get CTSM

Get CTSM for running (no source changes)

If you are a novice, that’s where you should start. You get the source code and run it as is.

NordicESMhub maintains a CTSM repository with all the configuration files for running on machines in the Nordics. For now we support:

• abel (UiO, Norway)

If you machine is not in the list and would like we support it, please contact us.

How to get a specific branch

Which branch do I run?

Get CTSM for modifying the source code

Create your own branches before continuing, in ~/ctsm AND in ~ctsm/cime. Do this for FATES or any other modules in addition.

git branch <username_clm5.0.12>   # useful for remembering version, name according to function e.g. username_cime_clm5.0.12 and username_fates_clm5.0.12
git checkout  <username_clm5.0.12>
git branch # to verify that you are on the branch you just created

When you need to do your own development.
