Global goal: Decision support system that analyses data from ships in
sea, models the environment and predicts (and prevents) dangerous situations.
\vskip\baselineskip
- Current goal: Real-time simulation environment for ships with visualisation.
+ Current goal: Accelerate the programme using graphical accelerators.
\vskip\baselineskip
Key features:
\begin{itemize}
- \item Real-time. We have 16--33 ms to compute everything.
- \item Realistic marine objects. We load ships from electronic blueprints.
- \item Arbitrary-amplitude ocean waves (work-in-progress).
+ \item Real-time visualisation. Without it we can not validate physics.
+ \item Realistic marine objects. We load ships from digital blueprints.
+ \item Wave reflection from ship hull (work-in-progress).

\frametitle{Motivation}
- \begin{itemize}
- \item Supercomputer facilities are scarce resource.
- \item Model basins are also scarce.
- \item Without real-time visualisation we can not validate physics.
- \item Regular workstations with a GPU can be used instead.
- \end{itemize}
