Virtual testbed performance was benchmarked in a number of tests. Since we use
both OpenMP and OpenCL technologies for parallel computing, we wanted to know
how performance scales with the number of processor cores and with and without

optimisation level including processor-specific optimisations which enabled
auto-vectorisation for further performance improvement.
+We ran all test for each of the three ship models: Aurora, MICW (a hull with
+reduced moments of inertia for the current waterline) and sphere. The first two
+models represent real-world ships with known characteristics and were taken
+from Vessel database~\cite{vessel2015} registered by our university. Parameters
