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. \subsection{Purpose}
