Installing CESM

Community Earth System Model (CESM) installation instructions are available via the README on the GitHub repository. The cube sphere grid is available as of CESM2.2.0.

Note

svn isn’t installed on the pfe nodes, thus the checkout_externals script fails because it is needed to download CESM/components/cam/chem_proc. To get around this issue, download CESM on a laptop or Cheyenne, tar the resulting file and transfer it to Pleiades.

Download CESM on a laptop or Cheyenne

cd <installation_directory>
git clone https://github.com/ESCOMP/CESM.git cesm2_2_0
cd cesm2_2_0
git checkout release-cesm2.2.0
./manage_externals/checkout_externals

Log on to a pfe node

cd /nobackup/$USER
sftp <user>@data-access.ucar.edu
get /glade/work/$USER/CESM.tar.gz
exit
tar -xvf CESM.tar.gz
