OpenMPI
Installing OpenMPI 1:
sudo apt-get install openmpi-bin openmpi-common libopenmpi1.10 libopenmpi-dev
GCC
Install GNU C complier 2:
sudo apt-get install build-essential
Verify:
whereis gcc make
gcc --version
make -v
Netcdf
Install Netcdf-c and Netcdf-f 3 4:
apt-get install libnetcdf-dev libnetcdff-dev liblapack-dev liblapack3 libopenblas-base libopenblas-dev
Set Netcdf Variables 5:
export ESMF_NETCDF="split"
export ESMF_NETCDF_INCLUDE=/usr/include
export ESMF_NETCDF_LIBPATH=/usr/lib/x86_64-linux-gnu
export ESMF_NETCDF_LIBS="-lnetcdff -lnetcdf"
Installing ESMF
Download ESMF Program
Create a directory:
mkdir /usr/local/esmf
Download source code:
cd /usr/local/esmf
wget http://www.earthsystemmodeling.org/esmf_releases/public/ESMF_7_1_0r/esmf_7_1_0r_src.tar.gz
Untar the file:
tar -xvf esmf_7_1_0r_src.tar.gz
Set Environment Variables
Check the variables:
make info
Set ESMF root Variable:
export ESMF_DIR=/usr/local/esmf/esmf
export ESMF_LAPACK="netlib"
Set following variables if they do not match in make info:
export ESMF_COMM=openmpi
export ESMF_COMPILER=gfortran
export ESMF_INSTALL_PREFIX=/usr/local/esmf/esmf
Build
cd $ESMF_DIR
make check
make install all
make build_apps
The ESMF Applications are located at /usr/local/esmf/esmf/apps/appsO/Linux.gfortran.64.mpiuni.default.
