Abstract
Four classes are created herein for classifying all the processes on a computer system which utilizes an ager and a paging based memory management. A first class will include all processes which have received repeated central processing unit (CPU) time slices after the last servicing by the ager. A second class will include all processes which have received some CPU time slices, less than a certain preselected threshold value, since the last servicing by the ager. A third class will include all processes which have not received any CPU time slices since the last servicing by the ager. A fourth class will include all processes which have received no CPU time slices for a certain predefined number of services by the ager. Once the processes are all classified, the ager will service the processes in the order of: Class 4, Class 1, and then Class 2. The processes in Class 3 will not be serviced.
