摘要:
A method for assembling swap blocks of virtual pages for transfer between a backing store and physical memory in a data processing system. The method includes segregating all virtual pages resident in physical memory between an active list and an inactive list. Virtual pages are then assigned to the inactive list by groups where each page in a group belongs to a single owning task or object. From a group, virtual pages are assigned to a swap block based upon correlation of most recent use. The swap block may then be paged out in a single operation to a backing store. A list of the group members is kept to permit page in to physical memory upon reference to a member of the swap block.
