Method and system for dynamically changing page types in unified scalable shared-memory architectures

摘要

According to one aspect of the invention, there is provided a method for dynamically changing page types in a unified scalable shared-memory architecture. The method includes the step of assigning a default page type of a given page as simple cache only memory architecture (SCOMA). Upon n memory references, a first parameter of the given page is calculated. A second parameter of the given page is calculated, when the first parameter is greater than a first threshold. The page type of the given page is dynamically changed to cache-coherent non-uniform memory architecture (ccNUMA), when the second parameter is greater than a second threshold. The first and the second parameters are one of a page reference probability and one minus a page utilization, the second parameter being different than the first parameter. According to another aspect of the invention, the n memory references correspond to all pages. According to yet another aspect of the invention, the n memory references correspond only to the given page.
