Abstract: 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.

Abstract: A computer system includes a local area network (LAN) and a plurality of computers. Each of the computers includes at least one central processing unit (CPU) and a LAN interface, which is coupled to communicate over the LAN, while the computers include no on-board input/output (I/O) device controllers other than the LAN interface. One or more peripheral devices are coupled to communicate with the computers over the LAN.
