Current cesm docker images are built on the openEuler⁠. This repository is free to use and exempted from per-user rate limits.

The Community Earth System Model(CESM) is a fully coupled global climate model developed in collaboration with colleagues in the research community. CESM provides state of the art computer simulations of Earth's past, present, and future climate states.

⁠Supported tags and respective Dockerfile links

The tag of each cesm docker image is consist of the version of cesm and the version of basic image. The details are as follows

⁠Usage

Here, users can select the corresponding {Tag} and container startup options based on their requirements.

• Pull the openeuler/cesm image from hub.docker.com

  docker pull openeuler/cesm:{Tag}
  

  Copy

• Start a cesm instance

  docker run -it --name my-cesm openeuler/cesm:{Tag}
  

  Copy

  This will give you a bash prompt like this:

  [root@cesm ncar]$
  

  Copy

  From here, you can follow the standard CESM documentation on creating/building/submitting cases. In this case, the submission runs in the foreground. An example set of commands to build a 2-degree F2000climo (scientifically unsupported, just used as an example) case, with a case name / directory of 'mycase' follows:

  create_newcase --case mycase --compset F2000climo --res f19_g17 --run-unsupported
  cd mycase
  ./xmlchange NTASKS=4
  ./case.setup
  ./case.build
  

  Copy

  It finishes successfully as follows:

  Time spent building: 289.431136 sec
  MODEL BUILD HAS FINISHED SUCCESSFULLY
  

  Copy

  This will require about 7-10GB of RAM for 1-4 tasks - if you haven't configured your Docker environment to allow that, you'll need to change that under Docker's settings.
