GROMACS version: 2023  
GROMACS modification: Yes/No  
Hi everyone,

I installed gromacs 2023 in windows based on a youtube video ([https://www.youtube.com/watch?v=1avdj8PLdKk](https://www.youtube.com/watch?v=1avdj8PLdKk)). Also, installed CUDA in windows. After gromacs installation, everything goes well and mdrun uses all CPU. But when I want to use GPU, mdrun doesn’t work.

I hope someone tell me what should I do.  
thank you.
