PLASIM

Gerneral Circulation Models Planet Simulator (PlaSim) and PUMA. These models are research models of intermediate complexity used in Meteorology and Earth Sciences.

Documentation

Manuals are located in:

• puma/doc for the PUMA model
• plasim/doc for the Planet Simulator

Installation

To build PlaSim using CMake:

mkdir build && cd build
cmake ..
make -j4
make install

The installation directory can be specified by adding the argument -DCMAKE_INSTALL_PREFIX=... to cmake.

Further options can be enabled/disabled:

• WITH_GUI (to display a diagnostic GUI while running, default OFF),
• WITH_LSG, WITH_COUPLER (compile and couple the LSG ocean model, default OFF),
• WITH_MPI (enable MPI for multiprocessor runs, default ON).

Further settings can be set using these variables:

• nlats (number of latitudes, default 32 64)
• nlevs (number of vertical levels, default 10 20)
• npros (number of processors, default 1 4, 1 if MPI is not enabled.).

These variables can be lists of multiple values, in which case a binary for each possible combination will be compiled.

For example, instead of cmake .. in the above, one can do

cmake -Dnlats=32 -Dnlevs=10 -DWITH_MPI=OFF ..

to compile a single binary.
