[torqueusers] configuring node to use subset of available physical GPUs

If I configure a compute node (in its server_priv/nodes file) to use X number of
GPUs where X < N and N = total number of physical GPUs in the system, are the first X
physical GPUs in the system always the ones that are allocated to jobs that
require GPUs? In other words, does the above configuration guarantee that torque
will never allocate the remaining N-X remaining GPUs to jobs?

I'm using torque 4.5.0pre1 on Ubuntu 13.10 with the built-in scheduler.
