  I already have a VMD installation on Blue Waters, so
there's no need for you to install your own unless you are
customizing it in some way. My installation also adds support
for BW-specific capabilities such as MPI, OpenGL off-screen rendering
via Pbuffers, and GPU-accelerated ray tracing using OptiX.

Are you planning to run VMD solely for analysis, or do you want
to do visualization on BW as well? The way you run the BW version
of VMD depends on what you're trying to accomplish. I can give you
examples if you tell me more about what you want to do with VMD on BW.
