install SWAN on RPM-based Linux distributions

prerequisites

The following packages must be installed first:

  • gcc

  • cmake

  • ninja

  • git

  • perl

  • intel-fortran-essentials

These packages can be installed using the default package manager dnf.

First, update the system

sudo dnf -y update

Next, run the following command to install GCC (GNU Compiler Collection) on the system

sudo dnf -y install gcc

To install cmake, enter

sudo dnf -y install cmake

Finally, install ninja by running the following command

sudo dnf -y install ninja-build

Warning

On AlmaLinux OS 9 and Rocky Linux 9, this command must be preceded by the two commands below:

sudo dnf -y install dnf-plugins-core
sudo dnf config-manager --set-enabled crb

Note that both AlmaLinux 8 and Rocky 8 install an older version of Ninja, namely 1.8.2, while CMake requires 1.10+ in order to build fortran. So if possible, please upgrade to a higher OS version.

On Oracle Linux 9 ninja should be installed as follows:

sudo dnf --enablerepo=ol9_codeready_builder install ninja-build

Install both git and perl in the following way:

sudo dnf -y install git

The final step is to install the Intel Fortran Essentials package which also includes the MPI libraries. First, create the repository file in the /temp folder:

tee > /tmp/oneAPI.repo << EOF
[oneAPI]
name=Intel(R) oneAPI repository
baseurl=https://yum.repos.intel.com/oneapi
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://yum.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB
EOF

Next, move this repo file oneAPI.repo to the yum configuration folder /etc/yum.repos.d:

sudo mv /tmp/oneAPI.repo /etc/yum.repos.d

Finally, install the package with the following command:

sudo dnf -y install intel-fortran-essentials

Let your OS system know where to find the compilers and libraries:

echo export INTF=/opt/intel/oneapi >> ~/.bashrc
echo "source \$INTF/setvars.sh > /dev/null 2>&1" >> ~/.bashrc
source ~/.bashrc

verify installations

Verify the required installations by checking their versions, as follows

ifx --version

cmake --version

ninja --version

perl --version

git --version

If no error is reported, then the installation was successful.

Important

  • The CMake version must be at least 3.20 or newer.

  • The ninja version should be at least 1.10.

  • The perl version is 5 or higher.

installation SWAN

Once the prerequisites are taken care of, installing SWAN on your machine is a four-step process.

  1. download SWAN

git clone https://gitlab.tudelft.nl/citg/wavemodels/swan.git && cd swan

Paste this into a shell terminal.

  1. configure SWAN

make config

  1. build SWAN

make

  1. install SWAN

make install

SWAN is installed at folder $HOME/wavemodels/swan by default. To run SWAN, you need to make sure that the /bin folder in this directory is added to your system’s PATH. Open the terminal and enter

echo export PATH=$PATH:$HOME/wavemodels/swan/bin >> ~/.bashrc
source ~/.bashrc

options for configuring SWAN

If desired, the build can be configured by passing one or more options below to make config.

fc=<compiler>

the Fortran90 compiler to use [default is determined by CMake]

mpi=on

enable build of SWAN with MPI [off by default]

metis=on

enable build of SWAN with Metis [off by default]

prefix=<folder>

set the installation folder [$HOME/wavemodels/swan by default]

For example, the following command

make config fc=ifx prefix=/usr/local/swan

will configure SWAN to be built using ifx and then install it at /usr/local/swan.

building with MPI support

The SWAN source code also supports memory-distributed parallelism for high performance computing applications. A message passing approach is employed based on the Message Passing Interface (MPI) standard that enables communication between independent processors.

The Intel Fortran Essentials package also contains the Intel MPI Library. This can be checked with the following command:

mpirun --version

We proceed to build SWAN. First, we configure SWAN to be built with support for MPI, as follows

make config fc=mpiifx mpi=on

The actual building is done by typing

make

Finally, to install SWAN, run the following command

make install

SWAN is now ready for high performance computing.

building with Metis support

SWAN can be compiled with support for Metis to partition an unstructured mesh so that simulations can be carried out on distributed-memory machines. For this, an MPI implementation is still required, click here for details.

The actual mesh partitioning implemented in SWAN is the multilevel k-way method as explained in the Metis manual.

For a proper building, the Metis software package must be installed first on your machine.

On a RPM-based Linux (e.g., Fedora):

sudo dnf -y install metis-devel

or, if that does not work (e.g., on Rocky Linux 8), enable the development repository:

sudo dnf -y --enablerepo=devel install metis-devel

However, on AlmaLinux 9+ and Rocky 9+ the development packages are moved to the CRB (CodeReady Builder) repo. In this case, run the following commands:

sudo dnf config-manager --set-enabled crb
sudo dnf makecache
sudo dnf -y install epel-release
sudo dnf -y install metis-devel

On Oracle Linux 9 Metis should be installed as follows:

sudo dnf -y install epel-release metis-devel

After Metis has been installed we continue with the build of SWAN. First, configure SWAN:

make config fc=mpiifx mpi=on metis=on

Next, build SWAN:

make

And finally, install SWAN:

make install

clean up

To remove all files installed by make install, type the following command

make uninstall

If you want to remove the build directory and all files that have been created after running make or make build, then run

make clobber
