hello:

   I've got two GTX590 at a workstation and I am trying to run two
series CUDA jobs in two different folder. I found that one is with 20
ns/day and the left is only 6 ns/day. The system is the same. I am
curious that the second probably is use the same GPU with the first one
so that the efficiency is so slow.

   So, I am wondering, is it possible to specify GPU in pmemd.CUDA
command so that two jobs won't use the same GPU for computation? I am
using SUSE LINUX OS.

thank you very much
Albert
