CISM exercise I: build model
The first step is to acquire the model code. In common with many open-source projects, there are regular releases of CISM — these are numbered snapshots of the code and represent stable versions of the model (relative to development versions of the code on the repository). The latest release can be downloaded from the CISM website:
Because we are currently working on readying Glimmer-CISM-2.0 for release, the most recent publicly available version on the code does not contain many recent updates that we would like to take advantage of in this coarse. For that reason, we will be working from an intermediate version of the code:
Click on the link above and save the tarball to your own CISM directory. To unpack the tarball, type
tar -xzvf CISM-BNU-3-2011.tar.gz
To build the code, you need to first cd into the correct directory
CISM uses autotools to build the code. First, we need to build the build system by typing
Next, we need to tell the configure script where to build the code, where to look to find the necessary NetCDF libraries, and which fortran compiler we want to use to build the code:
./configure --prefix=/path-where-you-want-build-CISM --with-netcdf=/path-to-netCDF-library FC=gfortran F77=gfortran
Check to make sure that the configuration step was successful with
If you see 'configure: exit 0' as the final line then configure was successful. Now, we type
make; make install
to first compile the various pieces of code and then build the model in the installation directory that you specified in when you ran configure. Note that if you want to build the code in the same directory where it was untarred you can simply do
./bootstrap ./configure --with-netcdf=/path-to-netCDF-library FC=gfortran F77=gfortran make
The code will take a while to build. When it is done, and assuming you haven't seen any obvious errors, you can confirm a successful build by checking in the example-drivers/simple_glide/src/ directory. If there is an executable file there called simple_glide, then your build was successful. This is the executable we will use to run the various test cases uses the higher-order dynamics version of the model.
