A CTOS3 network (Fig. 1) comprised of a plurality of workstations (WS#1-WS#N) provides for virtual demand paging transparently across the network in a manner which permits a large virtual memory to efficiently be provided for each of a plurality of concurrently running applications (A1, A2, A3, Fig. 2) on a CTOS workstation (Fig. 2). Each application running on the workstation is provided with assigned pages (Pg1-PgN, Fig. 4) and a local clock (Fig. 4) which operates based on the well known clock algorithm. A unique combination of local policy and global policy is used for page replacement which results in significantly more efficient management of available memory pages. |
