Hi amber experts,

      I have a question about how to use pmemd.cuda.MPI for long time simulation. Because, I found that if applying this command like "mpirun -np 8 pmemd.cuda.MPI .... to use 82080Ti GPU, the simulation performance had been decreased to 12.5% of one GPU. What's wrong about this I just compiled the parallel version as manual guidance. How to fix this problem? Thanks for any suggestions.
