[gmx-users] cuda gpu status on mdrun

[Szilárd Páll]

Hi Quentin,

That's just a way of saying that something is wrong with either of the
following (in order of possibility of the event):
- your GPU driver is too old, hence incompatible with your CUDA version;
- your GPU driver installation is broken;
- your GPU is behaving in an unexpected/strange manner.

Note that GF 8400 is way too old and therefore incompatible with GROMACS,
you'll need at least a compute capability 2.0 card.

Cheers,
