Abstract
A dynamic cache management mechanism determines the amount of memory available from a system on which a memory intensive application is running and dynamically manages the amount of cache for which real memory is associated or committed by the system. A background thread periodically queries the operating system to determine how much memory is available for use by applications. If the amount of memory, as identified in a free list is above a predetermined threshold, the application requests more memory for its use. If below the predetermined threshold, the application gives memory back to the operating system. The threshold used by the application to expand and shrink the memory it uses based upon system demand for memory.
