GOAS version

Change into the directory 'gem':
Create and change into new branch
cd gem git checkout -b my_branch
From here on we will refer to this directory as the "gem" directory.
Create 'work' and 'build'
...
directories
In this the 'build' directory will be your:
- CMakeFiles
- module files
- object files and excecutables,
- executables
In the 'work' directory will be:
- copy of the excecutables
- model scripts,
- example config files,
- example database,
- and you will execute your simulation from here
Since this directory these directories can get large you must not create it them under your home but under you data space.
MY_WORK_DIR=/path/to/my/work/directory
After you created the work directory you need to create some symbolic links to this directory:
mkdir -p ${MY_WORK_DIR}/build
ln mkdir -s p ${MY_WORK_DIR} MY_WORK_DIR/work
mkdir ln -s ${MY_WORK_DIR}/build
ln -s ${MY_WORK_DIR}/buildwork
Download database
GOAS comes with it's own database (initial conditions, geophysical & climatological fields, driving data). You only need to download it if you want to run any of the GOAS test configurations. Before downloading it I suggest you create a directory for it outside your home and create a symbolic to this directory, called 'gem_dbase'. For example:
mkdir ${MY_WORK_DIR}/work/gem_dbase
ln -s ${MY_WORK_DIR}/work/gem_dbase
Then you can download it with:
...
| Ancre | ||||

Set compiler version and
...
create Makefiles
Change into the 'gem/build' directory under which you downloaded your source code and make sure you did export our work directory - see above:
MY_WORK_DIR' export MY_WORK_DIR=/path/to/my/work/directory(In case you forgot where this directory is, just check where your link 'directory points to.)
Also, to make things easier further down, set MY_GEM_DIR to the name of your "gem" directory - see above (replace the '...' in the following command!):
export MY_GEM_DIR=.../gem
Change into the 'gem/build' directory:
cd ${MY_GEM_DIR}/build
Depending on which machine you work and which compiler or environment you want to use the commands differ a little. Here are some options:
...
module load openmpi/2.1.5-intel-19.0-mkl
module load utils/misc # to Only on CentOS 7 servers! To get an up to date version of cmake
cmake -DCOMPILER=intel -DCMAKE_VERBOSE_MAKEFILE=ON -DWORK_PREFIX=${MY_WORK_DIR} ${MY_GEM_DIR}/project
