摘要： A method and structure is disclosed for constraining cache line replacement that processes a cache miss in a computer system. The invention contains a K-way set associative cache that selects lines in the cache for replacement. The invention constrains the selecting process so that only a predetermined subset of each set of cache lines is selected for replacement. The subset has at least a single cache line and the set size is at least two cache lines. The invention may further select between at least two cache lines based upon which of the cache lines was accessed least recently. A selective enablement of the constraining process is based on a free space memory condition of a memory associated with the cache memory. The invention may further constrain cache line replacement based upon whether the cache miss is from a non-local node in a nonuniform-memory-access system. The invention may also process cache writes so that a predetermined subset of each set is known to be in an unmodified state.

摘要： In a computer system having an operating system and a compressed main memory defining a physical memory and a real memory characterized as an amount of main memory as seen by a processor, and including a compressed memory hardware controller device for controlling processor access to the compressed main memory, there is provided a system and method for managing real memory usage comprising: a compressed memory device driver for receiving real memory usage information from the compressed memory hardware controller, the information including a characterization of the real memory usage state: and, a compression management subsystem for monitoring the memory usage and initiating memory allocation and memory recovery in accordance with the memory usage state, the subsystem including mechanism for adjusting memory usage thresholds for controlling memory state changes. Such a system and method is implemented in software operating such that control of the real memory usage in the computer system is transparent to the operating system.
