Chansup,
Yup - been there, done that. On all my execution hosts I have set
"slots" to 8 since they are 8 core machines. The command "qhost -F
slots" does indeed tell me the number of currently available slots on
each host - 8 for an empty node, zero for a fully occupied node, or
something in between as the case may be. This actually relates to
another thread regarding preventing over-subscription when an execution
host serves multiple cluster queues.
So have you actually observed job packing to work on your cluster(s)?

Hi James,
I jumped in this thread later but I'm not sure if you already made the
following change. This configuration change is necessary to make
GridEngine to pack your job on a node.
You need to add the following in your exechost configuration:
complex_values slots=<Nslots>
If you execute the following command, it will show whether it is added or not.
qhost -F slots
