The source code tar files of WRF and WPS (V3.7.1) have been downloaded and placed in the subdirectory /projects/WRF/Downloads on the RAIJIN cluster. The uncompressed source code for V3.7.1 of WRF and WPS, which have been ported to build on RAIJIN cluster, is located in the subdirectory /projects/WRF/WRFV_3.7.1.

Go to the WRFV3/ subdirectory, run:

Start with a clean installation before compiling WRF, run:
 
<syntaxhighlight>
 
./clean -a
 
</syntaxhighlight>
 
Configure and compile WRF, run:
 
<syntaxhighlight>
 
./run_compile
 
</syntaxhighlight>
 
You will be given four choices using Intel compiler. These choices range from compiling for a single processor job (serial), OpenMP shared-memory (smpar), to using distributed-memory (dmpar) or distributed Memory with shared memory (dm+sm).
 
<syntaxhighlight>
 
Please select from among the following Linux x86_64 options:
 
1. (serial)  2. (smpar)  3. (dmpar)  4. (dm+sm)  INTEL (ifort/icc)
 
Enter selection [1-4] :

Once an option is selected from above, a choice of what type of nesting (no nesting (0), basic (1), pre-set moves (2), or vortex following (3)) will be given.

Compile for nesting? (1=basic, 2=preset moves, 3=vortex following) [default 1]:

A file configure.wrf should be created after configuring has completed.
 
Then a compilation script, called wrf_compile, is submitted to the job queue by the run_compile script.
 
  
After a successful build, one should see the following executable files for WRF (the ARW core):
