Abstract: In an embodiment, a target number of discretionary pages for a first partition is calculated as a function of a number of physical page table faults, a number of sampled page faults, a number of shared physical page pool faults, a number of re-page-ins, and a ratio of pages. If the target number of discretionary pages for the first partition is less than a number of the discretionary pages that are allocated to the first partition, a result page is found that is allocated to the first partition and the result page is deallocated from the first partition. If the target number of discretionary pages for the first partition is greater than the number of the discretionary pages that are allocated to the first partition, a free page is allocated to the first partition.

Abstract: Computer keyboard control of the characteristics of a display device coupled to a computer through the basic input/output system (BIOS) of the computer is disclosed. In one embodiment, a computerized system includes a computer, a display device, and a keyboard. The display device is responsive to at least one display control command, each command associated with a characteristic of the display device, such as contrast or brightness. The BIOS, in response to detecting a predetermined sequence of keystrokes entered by the user on the keyboard, operatively sends the display device a corresponding display control command.

Abstract: A method and data processing system for graphically indicating a status of a circuit unit displayed within a circuit design on a display within a data processing system. The circuit unit displayed within the circuit design is selected, wherein the circuit unit is located at a location and has a first status. A movement of the selected circuit unit is detected. Whether the movement of the selected circuit unit changes the status of the selected circuit unit is determined. A status change of the selected circuit unit is automatically indicating by graphically indicating the status change in response to the change of status of the selected circuit unit, wherein the status of the selected circuit unit is dynamically indicated to a user in response to a movement of the selected circuit unit.

Abstract: A multiprocessor in which processing units have local private caches and records are stored on at least a first global storage control unit. An interconnection system provides node to node data and synchronization communications between processing units and the first global storage control unit. The global storage control unit includes a coherency controller for tracking each instance of records owned by the global storage control unit currently resident on the processing units. Each processing unit executes a cache management process for freeing intervals of the local cache for the processing unit. Upon identification of an interval, the processing unit sends empty notification to the global storage control unit owning the record an instance of which was resident in the interval. Thereafter the interval is marked as invalid in a cache directory for the processing unit and indicia for the instance is deleted from a coherency directory for the global storage control unit.

Abstract: A method and system for visually altering characteristics of an iconic representation in response to a user's interaction with an object within a data processing system. The user initially associates an iconic representation for each object and selects the information to be monitored for each object. Parameters which may be monitored include the number of times the user interacts with the object, the amount of time the user spent interacting with the object, or the passage of time. This information is then stored in a database. The user's interaction with each object is then monitored, and the visual characteristics of the iconic representations associated with each object are then altered in response to the user's interaction with each object.
