+One way of removing this barrier is to use graphical accelerator to speed up
+computations. In that case simulation can be performed on a regular workstation
+that has a discrete graphics card. Most of the researchers use GPU to make
+visualisation in real-time, but it is rarely used for speeding up simulation
+parts, let alone the whole programme. In~\cite{pita2016sph} the authors use GPU
+to speed up computation of free surface motion inside a tank.
+In~\cite{varela2011interactive} the authors rewrite their simulation code using
+Fast Fourier transforms and propose to use GPU to gain more performance.
+In~\cite{keeler2015integral} the authors use GPU to simulate ocean waves.
+Nevertheless, the most efficient way of using GPU is to use it for the whole
+programme: it allows to minimise data copying between CPU and GPU memory and
+use mathematical models, data structures and numerical methods that are
+tailored to graphical accelerators.
+
+The present research proposes a numerical method for computing velocity
+potentials and wave pressures on a graphical accelerator, briefly explains
+other methods in the programme, and presents benchmarks for asynchronous
+visualisation and simulation.

\section{Virtual testbed}
Virtual testbed is a computer programme that simulates ocean waves, ship motion
and compartment flooding. One feature that distinguishes it with respect to
existing proposals is real-time visualisation and the use of graphical
-accelerators for speeding up computations.
