cuEventCreate cuEventDestroy cuEventElapsedTime cuEventQuery cuEventRecord cuEventSynchronize

cuEventElapsedTime ( float *  pMilliseconds, CUevent  hStart, CUevent  hEnd   ) Computes the elapsed time between two events (in milliseconds with a resolution of around 0.5 microseconds). If either event has not been recorded yet, this function returns CUDA_ERROR_NOT_READY. If either event has been recorded with a non-zero stream, the result is undefined. Parameters: pMilliseconds  - Returned elapsed time in milliseconds hStart  - Starting event hEnd  - Ending event Returns: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_NOT_READY Note: Note that this function may also return error codes from previous, asynchronous launches.
