One important input the PAGG team could give is some real

is required and help us appreciate that position and let us
see how this would/could be done in CKRM.
One example would be the implementation of CPU sets (or pools) a la Solaris where there are named CPU pools to which processors and processes are assigned. Processors can be moved between CPU pools and when this happens it is necessary to visit all the processes that are assigned to the pools involved (one losing and one gaining the processor) and change their CPU affinity masks to reflect the new assignment of processors. PAGG would be ideal for implementing this.
At the same time, a resource management client could be controlling resources allocated to processes based on some other criteria such as the real user or the application being run without regard to which CPU pool they are running in.
