GROMACS version: 2023.3  
GROMACS modification: Yes (I think??)

I’ve just started setting up a new PC with the main goal of running MD simulations, and I’m trying to test out a simple membrane simulation generated by CHARMM-GUI. I installed GROMACS with GPU support, but I keep getting “Fatal error: Cannot run short-ranged nonbonded interactions on a GPU because no GPU is detected.” when I try to include “nb gpu” in my README file. Any insight would be greatly appreciated as I’ve never set up a PC or installed GROMACS on my own. Thank you so much!

Note that you have different versions of your CUDA driver and runtime. They need to be the same.

Oh my gosh, of course- that was such a silly mistake to miss. Thank you so much @jalemkul!
