install SWASH on Debian-based Linux distributions

prerequisites

The following packages must be installed first:

gcc
cmake
ninja
git
perl
wget
gnupg
intel-fortran-essentials

These packages can be installed using the package manager apt.

Open a command line terminal and run the following commands:

sudo apt -y update

followed by

sudo apt -y install build-essential cmake ninja-build git wget gnupg

Note

The build-essential package installs essential tools and libraries for compiling the source code, including gcc and make.

The Linux flavors Debian, Ubuntu and Mint have perl installed by default.

The final step is to install the Intel Fortran Essentials package which also includes the MPI libraries. First, set up the Intel repository by downloading the key to system keyring:

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

followed by adding 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

Next, update the repository index:

sudo apt update

Finally, install the package with the following command:

sudo apt -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 SWASH

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

download SWASH

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

Paste this into a shell terminal.

configure SWASH

make config

build SWASH

make

install SWASH

make install

SWASH is installed at folder $HOME/wavemodels/swash by default. To run SWASH, 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/swash/bin >> ~/.bashrc
source ~/.bashrc

options for configuring SWASH

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 SWASH with MPI [off by default]

prefix=<folder>

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

For example, the following command

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

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

building with MPI support

The SWASH 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 SWASH. First, we configure SWASH 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 SWASH, run the following command

make install

SWASH is now ready for high performance computing.

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
