How to list CUDA devices in windows 7 using cmd?

Question

How to display as a list CUDA availible devices in windows 7 using command line?

Do I need to install additional software to do this?

Solution 1

In directory C:\Program Files\NVIDIA Corporation\NVSMI there is an utility nvidia-smi.exe it can query lots of different stats about your GPUs. To list all GPUs in your system run it with -L option.

Solution 2

I suggest to compile and execute the deviceQuery example.deviceQuery source here

nvidia-smi command line tool (it comes with CUDA installation) is also a very useful. It shows you information regarding the GPUs used, the current load of each of them (memory/power/cores), and the processes that are running on CUDA. Take a look at the following for as an example:
