I would recommend to partition the hosts (whatever is easy to implement
for you: namespaces, containers, virtual machines, ...)
Out of necessity we have Slurm running with Ganeti KVM instances (type
"plain") as virtual Slurm nodes to protect infrastructure VMs (type
"DRBD" & "plain") on the same hosts
-- with no obvious performance penalties.

I don't know how Torque tracks resource usage (could it handle an
/external/ process -- your host suddenly having load from /somewhere/
else?).
AFAIK Slurm can only track resources it scheduled itself.

Regards,
Benjamin

Sure - all you have to do is pull some nodes out of the Torque configuration 
(so Torque doesn’t know they exist), and then install Slurm on those nodes 
(adding just those nodes to the slurm.conf file).
