Install MITgcm

Get the code and documentations

The MITgcm code is available at:

http://mitgcm.org/public/source_code.html

After downloading the code (we are using c66h version of MITgcm, other versions should be fine), open the file in $HOME/scripps_kaust_model/:

tar -xf MITgcm_c66h.tar.gz

Enter the folder:

cd $HOME/scripps_kaust_model/MITgcm_c66h/

Compile the code

Below are the steps to compile the MITgcm test cases.

Compile the code using default setup

To compile the code using the default setup is straightforward with only a few steps. First, you need to cd to one of the cases, for example:

cd ./verification/tutorial_barotropic_gyre/

where $MITGCM_DIR is the location of the MITgcm folder.

Then, run the following commands to compile using GNU without MPI (default gfortran compiler):

cd build
../../../tools/genmake2 "-mods" "../code"
make depend
make

After the code is successfully built, an executable file mitgcmuv can be seen in the build folder. Using the default compiler is very simple, but sometimes the user would need to add more options when compiling the code.
