Downloading CESM2
Following CESM2 Quick Start Guide and CESM2 github instructions.
Cloning the code for version 2.2.2:
$ mkdir -p CESM/v2.2.2/intel git clone -b release-cesm2.2.2 git@github.com:ESCOMP/CESM.git my_cesm_sandbox
This will create a directory my_cesm_sandbox/ in your current working directory.
We got the following
$ cd my_cesm_sandbox/ $ ls ChangeLog CODE_OF_CONDUCT.md Externals.cfg manage_externals ChangeLog_template describe_version Externals_cime.cfg README.rst cime_config doc LICENSE.txt
Verifying that installation was fine:
$ ./manage_externals/checkout_externals $ ls ChangeLog CODE_OF_CONDUCT.md Externals.cfg README.rst ChangeLog_template components Externals_cime.cfg cime describe_version LICENSE.txt cime_config doc manage_externals
Defining the compilation / installation
Machine
We need to create the configuration for hydra. For that purpose we are going to use the exampled configuration for"centos7-linux" from file cime/config/cesm/machines/config_machines.xml. This is its content:

Work-flow
configuration of the work-flow is done via the fileconfig_batch.xml
http://esmci.github.io/cime/versions/master/html/users_guide/machine.html
Necessary additional components
ESM
It is necessary the High Performance Modeling Infrastructure (ESM) in May 2024, the latest version was the 8.6.0 and is the one being installed.
Getting the code in hydra in folder ESM
$ wget https://github.com/esmf-org/esmf/archive/refs/tags/v8.6.0.tar.gz
Compilation is done following these documentation, which the right detailed procedure specific-compilation-instructions.
GNU compilation
Installation location
$ mkdir -p v860/gnu $ cd v860/gnu $ tar xvfz ../v8.6.0.tar.gz $ cd esmf-8.6.0/ $ ls build build_config cmake LICENSE makefile README.md scripts src
Starting by defining the location of the code
$ export ESMF_DIR=$PWD
Running to get local information
$ make info >& run_make_info.log
Launching the makefile in parallel:
$ make -j8 lib >& run_make.log $ tail run_make.log (...) ESMF library built successfully on Mon 13 May 2024 12:58:46 PM -03 To verify, build and run the unit and system tests with: make check or the more extensive: make all_tests
Verifying that installation worked fine
$ make all_tests >& run_make_tests.log
intel compilation
Loading hydra's intel compilation environment
$ source /opt/load-libs.sh 1
Installation location
$ mkdir v860/intel $ cd v860/intel $ tar xvfz ../v8.6.0.tar.gz $ cd esmf-8.6.0/ $ ls build build_config cmake LICENSE makefile README.md scripts src
Porting and validating CIME on a new platform
http://esmci.github.io/cime/versions/master/html/users_guide/porting-cime.html
Downloading the Input data
All input data will be downloaded in
/share/cesm
Input datasets are needed to run the model. CESM input data are available through a separate Subversion input data repository.
- Change check_input_data header so it runs with Python 2.7.x version:
sed -i -e 's!/usr/bin/env python!/share/anaconda2/bin/python!' ./cime/scripts/Tools/check_input_data
