CUresult cuDeviceGetCount ( int *  count  )  Returns in *count the number of devices with compute capability greater than or equal to 1.0 that are available for execution. If there is no such device, cuDeviceGetCount() returns 0. Parameters: count  - Returned number of compute-capable devices Returns: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE Note: Note that this function may also return error codes from previous, asynchronous launches.
