Ok, so I create a new queue, gpu.q, that only has that node, with the complex
value for the gpu. I removed the node from @allhosts so that the all.q and
interactive.q don’t use the node. I also modified the user list so that only
users authorized to use the GPU can use the node.
But now I am told that this is not recommended. ??

The docs I have found are rather cryptic.
Assuming you want other people to be able to use the node but not the GPUs
I would think the process would be:
1)Define the resource in the complex_values of a queue that exists only on
the node in question.
2)Add the Grid Engine ACL to the queue.
3)Ensure all resources shared between gpu and non-gpu jobs (including
slots/cpus) are defined on the
host rather than the queue.
You might want to set up the prolog and epilog to twiddle the permissions
on the /dev/ files representing
the GPUs so only the job can access them to enforce access.
