  48 /*! \brief Checks if there is a compatible GPU to run the computations on
  49  *
  50  * There are several reasons why code can not rune on the GPU:
  51  * 1. The GPU can not be detected, because there is none in the system.
  52  * 2. GPU detection is disabled by GMX_DISABLE_GPU_DETECTION environmental variable.
  53  * 3. GPUs are detected, but none of them is compatible.
  54  * This function checks all these conditions and returns true only if there at least
  55  * one GPU that can be used for computations.
  56  *
  57  * \returns True, if there a GPU that can be used for computations
