Abstract
A rule-based method for pre-fetching “important pages” from memory paging space back into kernel memory space performs the following steps: (i) establishing a first machine logic based rule, with the machine logic based rule including a first triggering condition and a first consequential responsive action; (ii) determining that the first triggering condition has occurred; and (iii) in response to the determination that the first triggering condition has occurred, performing the first consequential responsive action. The first triggering condition includes the following sub-conditions: (i) at least one of a first set of important page(s) of a computer system has been paged out of kernel memory space and into paging memory space, and (ii) a processing status of the computer system indicates that the first set of important page(s) will be likely to be required for computer operations.
