Abstract
A system and method for enabling applications to pin a set of pages in memory for a predetermined duration in time. An application submits a request for pinning its memory for certain duration. As a compensation the applications may offer other currently mapped pages for replacement. The request may also include number of pages and duration of time. The request is granted with the constraint policies which the application is to follow. Such constraint policies include number of pages and length of time the pages may remain pinned in memory. When compensation pages are offered, those pages are replaced in place of the pages which are granted the privileged of being pinned. The present invention also provides page coloring compensation by including a compensation pool from where a compensation page having the same color as the one picked for replacement may be selected. The compensation pages offered by the application which are not used for compensating are returned subsequently to the application.
