Abstract
A system for computer memory management that implements a memory pool table, the memory pool table including entries that describe a plurality of memory pools, each memory pool representing a group of memory pages related by common attributes; a per-page tracking table, each entry in the per-page tracking table used to related a memory page with a memory pool of the memory pool table; and processing circuitry to: scan each entry in the per-page tracking table and, for each entry: determine an amount of memory released if the memory page related with the entry is swapped; aggregate the amount of memory for the respective memory pool related with the memory page related with the entry in the per-page tracking table, to produce a per-pool memory aggregate; and output the per-pool memory aggregate for the memory pools related with the memory pages in the per-page tracking table.
