36 * \brief Leap-Frog tests runners.
38 * Declares test runner class for Leap-Frog algorithm. The test runners abstract
39 * class is used to unify the interfaces for CPU and GPU implementations of the
40 * Leap-Frog algorithm. This allows to run the same test on the same data using
41 * different implementations of the parent class, that inherit its interfaces.
