Hi,
    When I used "pmemd.cuda" to response my work, I found that the work just run with one GPU and one CPU, but there are multiple CPUs available. I want to run under one GPU with multiple CPUs, because maybe it will run more efficient. I first tried "mpirun -np xx(CPU numbers) pmemd.cuda -...", the work failed, then I found "pmemd.cuda.MPI" in the manual, but it works with multiple GPUs. I originally consider that "pmemd.cuda" will automaticly call multiple CPUs, but the result is not. Maybe some solutions about this problem I have missed, this problem is still on at present.
    I am looking forward to receiving your reply. Thanks!


Sincerely,
Meng,Wu
