First thing is that, there is no defined as CPU queuing. There is CPU run queue (which is basically an average no. of jobs over a period of time. It is also called as load average) and priority queue. (Which the actual jobs waiting to run)

run queue can be seen with
uptime
sar -qM 1 5

Global priority queue, can be checked with glance.

The real thing to look at is global priority queue.

PRM is software with which you can allocate system resouces to group of users. It can allocated in % share or cpu allocation. This is additional $$ product.
