How to install WRF/WPS with "Classic" Intel Compilers on Ubuntu

[William.Hatheway]

Good afternoon everyone.

Here is a set of instructions on how to install the WRF/WPS using the "Classic" Intel Compilers.
Classic = ifort, icc, icpc, mpiifort, mpiicc, and mpiicpc.

PASSWD is your sudo password

############################# Basic package managment ############################

    echo $PASSWD | sudo -S apt -y update

    echo $PASSWD | sudo -S apt -y upgrade

#download the key to system keyring; this and the following echo command are
# needed in order to install the Intel compilers

    wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB |
        gpg --dearmor | sudo tee /usr/share/keyrings/oneapi-archive-keyring.gpg >/dev/null

# add signed entry to apt sources and configure the APT client to use Intel repository:

    echo "deb [signed-by=/usr/share/keyrings/oneapi-archive-keyring.gpg] https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/oneAPI.list

# this update should get the Intel package info from the Intel repository

    echo $PASSWD | sudo -S apt -y update

# necessary binary packages (especially pkg-config and build-essential)

    echo $PASSWD | sudo -S apt -y install autoconf automake bison build-essential byacc cmake csh curl default-jdk default-jre emacs flex g++ gawk gcc gfortran git ksh libcurl4-openssl-dev libjpeg-dev libncurses5 libncurses6 libpixman-1-dev libpng-dev libtool libxml2 libxml2-dev m4 make mlocate ncview okular openbox pipenv pkg-config python2 python2-dev python3 python3-dev python3-pip tcsh unzip xauth xorg time

# install the Intel compilers

    echo $PASSWD | sudo -S apt -y install intel-basekit
    echo $PASSWD | sudo -S apt -y install intel-hpckit
    echo $PASSWD | sudo -S apt -y install intel-oneapi-python
    echo $PASSWD | sudo -S apt -y update

# make sure some critical packages have been installed

    which cmake pkg-config make gcc g++ gfortran

# add the Intel compiler file paths to various environment variables (THIS IS EXTREMELY IMPORTANT)

 source /opt/intel/oneapi/setvars.sh

# some of the libraries we install below need one or more of these variables. -diag-disable=10441 is for the removal of the warning that "Classic" compilers are going away.

    export CC=icc
    export CXX=icpc
    export FC=ifort
    export F77=ifort
    export F90=ifort
    export MPIFC=mpiifort
    export MPIF77=mpiifort
    export MPIF90=mpiifort
    export MPICC=mpiicc
    export MPICXX=mpiicpc
    export CFLAGS="-fPIC -fPIE -O3 -diag-disable=10441 "
    export FFLAGS="-m64"
    export FCFLAGS="-m64"

# Continue installation of libraries as normal according to the users guide

# Steps for installing WRF

Classic intel compilers is option 15 from the list
Basic Nesting is option 1 from the list
After generating the configure.wrf file you need to make some edits to it to use the intel mpi commands. This is taken from the configure.wrf file in the notes.

    sed -i '169s|mpif90 -f90=$(SFC)|mpiifort|g' $WRF_FOLDER/WRFV4.5.1/configure.wrf
    sed -i '170s|mpicc -cc=$(SCC)|mpiicc|g' $WRF_FOLDER/WRFV4.5.1/configure.wrf
    sed -i '177s|-w -O3|-diag-disable=10441 -w -O3|g' $WRF_FOLDER/WRFV4.5.1/configure.wrf

That removes the GNU commands for intel commands.


Then compile WRF.

#Steps for installing WPS

Classic intel compilers is option 19

After generating the configure.wps file you need to make some edits to it to use the intel mpi commands.

    sed -i '67s|mpif90|mpiifort|g' $WRF_FOLDER/WPS-4.5/configure.wps
    sed -i '68s|mpicc|mpiicc|g' $WRF_FOLDER/WPS-4.5/configure.wps

That removes the GNU commands for intel commands.

Then compile WPS.


Lastly,
To use WRF/WPS you will need to invoke this command every time you want to run it.

source /opt/intel/oneapi/setvars.sh

This turns on the intel compilers in the terminal.
