First make sure you have installed netCDF library, and set NETCDF_ROOT environment variable to it. Then clone the repository:

$ git clone https://gitee.com/dongli85/GMCORE gmcore
$ cd gmcore
$ git submodule update --init

You could build the model by following:

$ cd build
$ FC=mpiifort cmake ..
$ make -j8

There is a Python script run_tests.py, which will clone the testbed repository, and run several tests, but it assumes MPI to be installed or SLURM job manager is available:

$ ./run_tests.py -w <work_directory> --slurm -q <job_queue> -n <process_number> --ntasks-per-node <n>

It will take some time to run the tests. When the tests are finished, cd to <work_directory>, and use some visualization tools, such as Panoply, to view the results.
