The pre-built deviceQuery.exe that ships with CUDA is a console application, at least up to CUDA 11.1. You would want to run that from a command prompt. If you are running it from within an IDE, you may have to configure the IDE so it does not close the window in which it displays console app output when the app terminates. For reference, here is what is output when I run the executable delivered with CUDA 11.1 from a command prompt on my Windows system (note that the “zu bytes” appears to be a bug in the pre-built application when the format specifier %zu is used)
