Abstract

A system for dynamically allocating memory to a file buffer cache manager and a virtual memory space manager is provided. The file buffer cache memory is time stamped at times of acquisition and access, and the acquired virtual memory space memory is time stamped at times of acquisition and access. If the file buffer cache manager or the virtual memory address manager requests memory, the time stamps of the memories acquired by the file buffer cache manager and the virtual memory space manager are compared. The piece of memory which has the earlier time stamp is preempted and allocated to the manager which has requested memory.
