Hi all,
I'm pretty sure I have cuda 8 for the gtx 1080's but namd nightly build
from a few days ago won't run:

FATAL ERROR: CUDA error cudaGetDeviceCount(&deviceCount) in file
src/DeviceCUDA.C, function initialize
on Pe 0 (node1.cl.siue.edu): CUDA driver version is insufficient for CUDA
runtime version
But everything below says it is cuda 8... or am I seeing that wrong?
