Running VR-CESM with docker

svn login to access the source code

• The CESM version used is cesm2_2_beta01 that can only be accessible if you authenticate yourself properly. We pass a tarball containing .subversion folder which we used to authenticate ourselves.

First you need to instal subversion:

sudo yum install subversion -y

svn co https://svn-ccsm-models.cgd.ucar.edu/cam1/trunk_tags/cam6_1_014/components/cam

Remark: you may have to install subversion on your virtual machine:

sudo yum install subversion -y

Enter the correct username and password. Then create the corresponding tarball:

cd $HOME
tar cvf subversion.tar .subversion

We then save it in a folder that we pass when running the docker container:

mkdir -p /opt/uio/svn_config
mv subversion.tar /opt/uio/svn_config/

VR-CESM docker

Make sure inputdata is available (it won't download it as we suppose it is already on disk).

• The location of the inputdata is /opt/uio/inputdata
• The folder vr_cesm_config/ contains the changes required for running our Variable resolution grid (made by Colin M. Zarzycki)
• Model outputs are stored in /opt/uio/archive along with the case folder (it can be interesting to check timing).

Important: the folder /opt/uio/archive needs to be writable by unix group users (see Dockerfile) otherwise you will get a permission denied when running.

sudo chgrp -R users /opt/uio/archive
sudo chmod -R g+w /opt/uio/archive

You can check it:

ls -lrt /opt/uio | grep archive

You should have:

drwxrwxr-x.  8 centos users        4096 Nov  9 15:21 archive
