GROMACS version: gmx, version 2021-UNCHECKED
GROMACS modification: Yes/No

when i check gmx --version i notice the following:
CUDA driver: 11.40
CUDA runtime: 11.20

do I need to rebuild GROMACS?

thank you

No, newer driver is compatible with older runtime and more recently (I think since 11?) CUDA drivers are also forward compatible with runtime that only differ in minor version.
