It relies on nonlinear iterative minimization algorithm to solve
the quantitative inverse wave problem.

The code is written in \texttt{Fortran90} and uses \texttt{MPI}
and \texttt{OpenMP} parallelism.

Summer 2025, Eduard Occhipinti did his M2 internship in the Inria team Makutu,
working on the code Hawen. While the internship has been funded independently
by the team, his work was carried out in the framework of NumPEx.
Eduard has used the NVIDIA's NVHPC Toolkit and explored effective strategies
for parallelization on GPUs whilst maintaining the current combination of
\texttt{MPI} and \texttt{OpenMP} parallelism.
He has also introduced a recently released GPU accelerated sparse solver,
cuDSS, to evaluate its performance for the resolution of the global linear
system.
