[gmx-users] Driver 410 solved the issue. Re: Gromacs 5.1.4 with GTX 780TI on Ubuntu 16.04; upgraded with GTX1080TI

Dear Paul and Mark,

Thank you for the suggestions. I just upgraded NVIDIA driver from 384 to
410 and the problem is solved.

Regards,

I just built from a similar situation but also went to Ubuntu  Mint Tara 19
, cuda runtime 10 ( used the Nvidia web site .run version not the deb  - do
not install the driver from the toolkit ) added  the 410 driver from the
PPA and the system is quite happy.

I believe I ran across some information that suggests that the mixture of
Runtime 8, Cuda driver 9 and Ubuntu 16 is not a good mix.  I?ll try to look
for it later if you need further information

Paul
