it sounds like RQS limits might be what you want, where you can limit the total number of cores a single user can consume at one time, if they request more then the jobs will sit in the queue.
http://wiki.gridengine.info/wiki/index.php/RQS_Common_Uses to modify: qconf -mrqs so your queue might have 12 slots, for example, but a single user can only request 2 at a time, so 6 different people could use the node at once. The second part of your question i don't think is possible but I might be wrong.

There's something I'd like to do, but I don't know how to do it...or, more precisely, I don't know what it's called so I'm not sure what I should be looking for in the documentation. I'm administering a single computer. So, it manages the queue and also is where the jobs are run. I'd like to create queues that limit the number of threads that can be used. For example, suppose it has 4 cores and 4 x 2 = 8 threads. Is it possible to create queues that: 1) Can use at most n threads (i.e., n=2). If the user places something on the queue that uses 4 threads while running, the user's job is either killed or suspended. 2) Can stick to using only one core. So, if threads is n=2, then both threads are on the same core ("guaranteed"). I guess (2) is impossible...I'm not sure if the system knows which thread goes with which core. But I guess (1) is possible but I don't know which option to set. What I'd like to prevent is having a queue with 2 threads and users putting programs with 4 threads on it. (I'd rather create another queue with 4 threads so that they can put it on that queue instead.) Thank you for your help!
