     Load modules with `module load LIST-OF-MODULE-NAMES`, unload them one by one with `module unload LIST-OF-MODULE-NAMES`, unload all of them at the same time with `module purge`, get information about a specific module with `module show MODULE_NAME`. Modules may depend on each other. If the system is set up properly, a request to load one module will automatically load any other prerequisite ones.

 * *Configure WRF for compilation.* This will test the system to check that all libraries can be properly linked. Type `./configure`, pick a generic dmpar INTEL (ifort/icc) configuration (usually 15), answer 1 when asked if you want to compile for nesting, then hit enter. "dmpar" means "distributed memory parallelization" and enables running WRF in parallel computing mode. For test compilations or for a toy setup, you might also choose a "serial" configuration.
