Installing your own version of CESM
These instructions are for users who need to download their own version of CESM2.
Do not load the CESM module. If you have a cesm module loaded, unload it:
module unload cesmClone the version of CESM you want from the github repo:
git clone -b release-cesm2.2.0 https://github.com/ESCOMP/CESM.git my_cesm_sandbox
cd my_cesm_sandbox
./manage_externals/checkout_externals
The various Oscar-specific XML files needed to run CESM, including
- config_batch.xml
- config_compilers.xml
- config_machines.xml
can be obtained from this github repo. The easiest way to incorporate these files into your build is to place them in a directory named .cime within your home directory (i.e., ~/.cime). For example:
git clone https://github.com/brown-ccv/CIME_Oscar ~/.cime
To setup, build, and run a case on Oscar:
- 1.Load the necessary modules (line 1-7 below)
- 2.Move to the cime_scripts directory (line 8)
- 3.Create a new case, selecting your desired <CASENAME>, <COMPSET>, and <GRID > (line 9)
- 4.Move to your CASEROOT directory (line 10)
- 5.Setup the case (line 11)
- 6.Build the case (line 12)
- 7.Submit the case (line 13)

By default, component log files, history files, and restart files for your case will be placed in /gpfs/home/$USER/data/$USER/archive/<CASENAME>.
