+Virtual testbed is a computer programme that simulates ocean waves, ship motion
+and compartment flooding. One feature of this programme is that it visualises
+physical phenomena frame by frame as the simulation progresses. The aim of the
+studies reported here was to assess how much performance can be gained using
+graphical accelerators compared to ordinary processors when repeating the same
+computations in a loop. We rewrote programme's hot spots in OpenCL to execute
+them on a graphical accelerator and benchmarked their performance with a number
+of real-world ship models. The analysis of the results showed that data copying
+in and out of accelerator's main memory has major impact on performance when
+done in a loop, and the best performance is achieved when copying in and out is
+done outside the loop (when data copying inside the loop involves accelerator's
+main memory only). This result comes in line with how distributed computations
+are performed on a set of cluster nodes, which suggests using similar
+approaches for single heterogeneous node with a graphical accelerator.
