I have NAMD3 running with CUDA 10 on my cluster. I got a copy of the
source from gitlab.
It is in the devel branch, and it tagged as 3.0a9. I have compilation
instructions that are what I used (or at least what I think I used from
memory) on github.
Compilation with NAMD3 from there is basically the same as it would be
anywhere else. You need charm++ compiled, followed by NAMD itself. The
hardest part for me was actually sorting out which of the many openMPI
implementations installed on the cluster had the PMI backend so I could
just call srun if I wanted to do replica exchange stuff.
