Migrating WRF to Azure Step 3

This step of the tutorial will guide you through the process of recompiling WPS 3.3.1 with the PToolsWin development environment.

Prerequisites

Before you continue, make sure you have these software prerequisites:

1. An installation of HPC Linux with PToolsWin.

2. NetCDF for Windows.

3. WRF for Windows

Build WPS as a Windows Executable

1. Open a command line in your HPC Linux distro and load the PToolsWin module:

   module load ptoolswin
   module list
   

    

2. Navigate to the WRF directory you created in Step2:

   setenv WRFDIR ${HOME}/windows/WRF 
   cd $WRFDIR

    

3. Download and unpack the WPS source:

    

   wget http://www.mmm.ucar.edu/wrf/src/WPSV3.3.1.TAR.gz
   tar xzf WPSV3.3.1.TAR.gz
   

    

4. Apply paratools-WPSV3.3.1-patch to the WPS source code to add a new build configuration for PToolsWin:

   wget http://paratools.com/Azure/WRF/Step3/paratools-WPSV3.3.1.patch -O paratools-WPSV3.3.1.patch
   cd WPS
   patch -p1 < ../paratools-WPSV3.3.1.patch
   

    

5. Configure your environment with the same values as when you compiled WRF:

   setenv NETCDF ${HOME}/windows/netcdf-4.1.3
   setenv WRFIO_NCD_LARGE_FILE_SUPPORT 1
   setenv WRF_EM_CORE 1 
   setenv WRF_OS Windows
   

    

6. Configure WPS. Select Windows x86_64, PToolsWin, DM PARALLEL, NO GRIB2 (Option 5) ¹:

   ./configure

    

7. Compile WPS ²:

    

    ./compile |& tee compile.log
   

   Verify that the ptoolswin module is loaded before you begin compiling. You can view loaded modules with the command module list

    

8. If the compilation was successful, you should see three symlinks in the $WRFDIR/WPS folder:

   [paratools07] 142 > echo $WRFDIR
   /home/livetau/windows/WRF
   [paratools07] 143 > pwd
   /home/livetau/windows/WRF/WPS
   [paratools07] 144 > ls -l *.exe
   lrwxrwxrwx. 1 livetau livetau 23 Mar 25 14:09 geogrid.exe -> geogrid/src/geogrid.exe
   lrwxrwxrwx. 1 livetau livetau 23 Mar 25 14:10 metgrid.exe -> metgrid/src/metgrid.exe
   lrwxrwxrwx. 1 livetau livetau 21 Mar 25 14:10 ungrib.exe -> ungrib/src/ungrib.exe
   [paratools07] 145 >

   If any of these symlinks are missing or broken, check configure.log for errors ( do a case-insensitive search for “Error”) and try re-compiling. Otherwise, continue to Step 4.
