The only straightforward path is to use the openMP capabilities of plumed,
so MPI doesn't get involved. Basic info is here:

Warning: I haven't tried this, but it seems like it ought to work. But only
parts of plumed use openMP, so it may not help for your particular use case.

Making a version of pmemd.cuda.MPI where only thread 0 interacts with the
GPU sounds possible, but also sounds like a fair amount of coding work.
