Hello:
Any guess from the following error on running namd-2.9_cuda4.0 (two
GTX-680) MD on a sensitive metalloprotein?

Used ts=0.01fs. In contrast, with non-cuda namd-2.9, no problems even with
ts=1fs (in all cases all bonds, except water, free vibrating). Margin
enlarged to no avail. Even for minimization I had to use non-cuda code.
With CPU only, my hardware is too limited.
I understand that the error output is cryptic enough. Just a try.
thanks
