reaches a speedup not proportional to the amount of processing units
can be reached if the domains become small.
Parallel calculation of the shots will increase the number of processing units which can be used
and provide a linear speedup. But more memory has to be allocated (proportional to the amount of parallel calculated shots). In 3D the point where the domain decomposition
