nvidia cuda driver version

Hello:
It would be useful to know which version of nvidia cuda driver to use
for Linux-x86_64-CUDA binary (v. 2.8), or where to look for such
information from released software.

Unlike in the past with CPU machine, where I used stable Debian amd64
without problems, with GPU-CPU I was advised to better use updated
drivers, so that I am using Debian testing amd64. With alternate
success: driver 275.09.07-5 let NAMD (not VMD) run. Today, on
upgrading to 275.21-1, NAMD finds the cuda cards:

then, instead of reading NAMD conf file,

BUG software... NAMD ...CPU#2 stalk

Should latest night build be tried in such a case, or NAMD be compiled
on the specific machine? In the latter case, where to find appropriate
flags for a GPU-CPU machine?

Because of of dependencies, it would be a steep way (if practicable at
all) to try to install old nvidia drivers on current testing.

Thanks
