Replica exchange on GPU with OPA network and Slurm

Hello,

I would like to know if there is a way to configure NAMD and Charm++ to
run Replica exchange job with GPU support over several nodes on our
supercomputer?

We have a Intel Omni-Path network and our job scheduler is Slurm. Each
node has 4 V100 GPUs.

 From what I have seen on the mailing list, there are mutually
incompatible options to compile CHARM++ and NAMD to solve the different
problems.

What our users would like, is to run with NVidia GPUs on several nodes.

We run NAMD 2.13 and CHARM++ 6.10.1.

Best regards
