Is the CUDA API version and driver version always the same

The CUDA version obtained from cuDriverGetVersion, and the API version from the macro CUDA_VERSION.
Are they supposed to be always the same (assuming CUDA is correctly installed)?

          The CUDA_VERSION macro tells you which version of the CUDA API you are compiling your code against. cuDriverGetVersion() will tell you the most recent version of CUDA that the driver you're running with supports. So no, they don't have to be the same. For example, an application that was compiled for CUDA 9.x will run perfectly fine with a driver that supports CUDA 10…

                    How to test boost logger output in unit testing?

                    Image
                    up vote 1 down vote favorite My application uses BOOST_LOG_TRIVIAL to log messages. I thought it's good to check in test (gtest) that correct messages are written there in given scenarios. Is there a way to somehow access what was written there after code was called? Or does it first have to be mocked in some way? I have googled a lot for this and haven't found any instructions, so either I am asking wrong questions or no one thinks it should be done. c++ logging boost googletest boost-log share | improve this question edited yesterday ...
