======How to Compile WRF 3.2.1 suite of programs on HPC======

 *Can be downloaded from the [[http://www.mmm.ucar.edu/wrf/users/download/get_source.html|WRF-ARW site]].  Scroll to the bottom and click whether you are a new or returning user.  If you are new, you will have to fill out a simple for to register before downloading.  Returning users will only need their email address they previously registered with.@default

=====Prep=====
  -While in your home directory on hpc, open the file //.bashrc// with your favorite text editing program.  ex. (//vi// , //pico//)
  -Make sure that the following is included if using Portland Group compilers <code bash>#PORTLAND
PGI=/opt/pgi; export PGI
MANPATH=$MANPATH:$PGI/linux86-64/7.2/man
LM_LICENSE_FILE=$PGI/license.dat:$LM_LICENSE_FILE
PATH=$PGI/linux86-64/7.2/bin:$PATH
PATH=$PGI/linux86-64/7.2/mpi2/mpich/python32/bin/:$PGI/linux86-64/7.2/mpi2/mpich/bin:$PATH

#NETCDF
export NETCDF='/usr/local/netcdf'
export PATH=$NETCDF/bin:$PATH
export WRF_DIR='/home/austinbl/wrf311/WRFV3'
export PATH=$WRF_DIR:$PATH

#NCAR Graphics
export NCARG_ROOT=/usr/local
export PATH=$NCARG_ROOT/bin:$PATH

# for WPS
export JASPERLIB='/usr/local/lib'
export JASPERINC='/usr/local/include'
export PATH=$JASPERLIB:$JASPERINC:$PATH
</code>
  -After updating //.bashrc//, use the command<code>source .bashrc</code>
=====WRFV3=====

  -Download WRF version 3.2.1 which will come in the form of WRFV3.2.1.TAR.gz.
  -Then transfer the file to hpc with the command <code> scp file username@hpc.atmos.und.edu:/home/username </code>
  -Once the file is on hpc, you must untar and ungzip the file. <code> tar xzf filename </code>
  -Move to the WRFV3 and use the [[http://www.mmm.ucar.edu/wrf/users/docs/user_guide_V3/users_guide_chap5.htm#_Installing_WRF|online compilation instructions]].
    -If compiling with the Portland Group compilers, chose the following <code>4.  Linux x86_64, PGI compiler with gcc  (dm+sm)</code>
=====WPS=====

  -Download WPS and transfer to hpc as in WRFV3 steps 1 and 2.
  -Use the [[http://www.mmm.ucar.edu/wrf/users/docs/user_guide_V3/users_guide_chap3.htm#_How_to_Install|online compiling instructions]].  Make sure to use the same compiler as used with WRFV3.
