Dear all,
Following on this, I have found this information from the nvidia forums, but
unfortunately, I cannot use nvidia-smi -c 1 in a script without root (or
enough) permissions...

# Nvidia forum states nvidia-smi must be running continuously in the
background for a GPU mode to stay "set"
nvidia-smi -l -i 30 -lsa &
# Now actually set the modes to exclusive use by one host thread per GPU...
sudo nvidia-smi -g 0 -c 1
sudo nvidia-smi -g 1 -c 1
sudo nvidia-smi -g 2 -c 1
sudo nvidia-smi -g 3 -c 1
# Now list the compute modes we just set...
nvidia-smi -g 0 -s
nvidia-smi -g 1 -s
nvidia-smi -g 2 -s
nvidia-smi -g 3 -s

Subject: [AMBER] Select cuda ID device in PMEMD
Dear all,
Is there any chance to choose which cuda ID device to be used by
PMEMD.cuda.MPI? This could be good to avoid competition between different
jobs in the same node for the same GPUs.
Thanks a lot,
Gonzalo
