Abstract: A method and processor system that substantially enhances the store gathering capabilities of a store queue entry to enable gathering of a maximum number of proximate-in-time store operations before the entry is selected for dispatch. A counter is provided for each entry to track a time since a last gather to the entry. When a new gather does not occur before the counter reaches a threshold saturation point, the entry is signaled ready for dispatch. By defining an optimum threshold saturation point before the counter expires, sufficient time is provided for the entry to gather a proximate-in-time store operation. The entry may be deemed eligible for selection when certain conditions occur, including the entry becoming full, issuance of a barrier operation, and saturation of the counter. The use of the counter increases the ability of a store queue entry to complete gathering of enough store operations to update an entire cache line before that entry is dispatched to an RC machine.

Abstract: A method and processor system that substantially eliminates data bus operations when completing updates of an entire cache line with a full store queue entry. The store queue within a processor chip is designed with a series of AND gates connecting individual bits of the byte enable bits of a corresponding entry. The AND output is fed to the STQ controller and signals when the entry is full. When full entries are selected for dispatch to the RC machines, the RC machine is signaled that the entry updates the entire cache line. The RC machine obtains write permission to the line, and then the RC machine overwrites the entire cache line. Because the entire cache line is overwritten, the data of the cache line is not retrieved when the request for the cache line misses at the cache or when data goes state before write permission is obtained by the RC machine.

Abstract: A multi-threshold integrated circuit (IC) with reduced subthreshold leakage and method of reducing leakage. Selectable supply switching devices (NFETs and/or PFETs) between a logic circuit and supply connections (Vdd and Ground) for the circuit have higher thresholds than normal circuit devices. Some devices may have thresholds lowered when the supply switching devices are on. Header/footer devices with further higher threshold voltages and widths may be used to further increase off resistance and maintain/reduce on resistance. Alternatively, high threshold devices may be stacked to further reduce leakage to a point achieved for an even higher threshold. Intermediate supply connects at the devices may have decoupling capacitance and devices may be tapered for optimum stack height and an optimum taper ratio to minimize circuit leakage and circuit delay.

Abstract: An analysis tool for specifically identifying the cause and location of critical memory leaks within a large software system is provided. The analysis tool transparently adds multiple processing threads that collaborate to identify sources of potential memory leaks in the software being analyzed. These threads provide notifications of object classes executing in the software that have had excessive instance counts or have exceeded the average lifetime of an object. A stack walkback is performed on objects being monitored as an out-of-memory condition approaches and while there is still sufficient memory available to unwind and store the stack walkback. By saving the stack walkbacks just prior to the out-of-memory failure, the analysis tool operator is thereby provided sufficient information to make a final determination of objects that are possible candidates for memory leaks and subsequently modify the software to reduce or eliminate the memory leaks.

Abstract: A graphical user interface and method for data entry of a plurality of fields of information in a computer system, such as a web browser interface, using small scrolling and paging of tabular data and entry fields. A JAVA script is employed to produce a form-like user interface in which a user may enter information in fields shown in a graphical user interface (“GUI”) window display area. The GUI is provided with a NEXT button which allows the user to indicate that he or she has more data to enter than can be entered in the currently available view of the form in the GUI window display area. The script saves the currently entered data into a set of hidden fields or variables, and provides a new screen with clear fields for additional data entry. By selecting the PREVIOUS button provided by the JAVA script on the GUI, the user may cause the script to recall previously saved data from the hidden fields or variables and to redisplay them so that the user may review or edit previously entered information.

Abstract: A method, system, and program product for a new intercommunication architecture in a modular computer system environment. The Information Kit is a publish-and-subscribe software bus applied as an application programming model on an embedded device. Each module of the modular computer system is connected to a virtual node on the information kit and each node operates as a subscriber/listener to the entire software bus. During setup of the module, the module sends a request to the Information Kit. An information kit manager (processor) logs the request in a register. Data (or information) is published by devices connected to other nodes of the Information Kit and the data is placed in a queue for publication to the requesting nodes. The information manager notifies the modules of the availability of the data and initiates a directed broadcast of the data to the modules requesting that particular data.

Abstract: A method and system for recovering a server blade, in a multiple server blade computer, that is lost during a flash update operation on a service processor in the server blade. Because of the flash update failure, the lost server blade is unaware of its location on a management pathway, which in an exemplary form may be a midplane or a bus, which connects the server blade and a management module in a server blade chassis. The lost server blade puts a signal on the management pathway indicating that the flash failed. The signal is put on a special channel reserved for such messages. The management module receives the signal, and then determines which of the multiple server blades are lost due to the flash update failure.

Abstract: An Ephemeral List navigation panel provided in conjunction with an Object-Action navigation tool which is a temporary “parking space” for objects encountered within other portions or modules of the Object-Action navigation tool. The panel represents a history, preferably in the form of a push-down stack, of products and/or objects encountered by the user. Items and objects within the panel are selectable by the user, and may be acted upon as indicated by the user such as adding, deleting, filtering and sorting them. The panel may be populated directly or indirectly by other processes associated with the Object-Action navigation tool, and the panel may cause actions within the other processes directly or indirectly responsive to user actions on the panel.

Abstract: A method is provided for allowing a database search that prevents an owner of the database or someone intercepting the database search in the network from knowing the contents of the query, without requiring any particular processing on the part of the database. Client 20 accesses database server 10 which stores sequence patterns and inquires whether the sequence patterns stored in the database server 10 exist in a predetermined sequence. Client 20 comprises sequence processing section 21 for dividing a search sequence subjected to search to create multiple subsequences; and query issuing section 22 for issuing a query to database server 10 using the created multiple subsequences individually as a query sequence.

Abstract: A programmable alarm clock system, method of operation and program product therefor with sleep analysis to identify and wake a person during non-REM sleep patterns, resulting in less subsequent drowsiness and better day-to-day functioning. The programmable alarm clock system includes at least one brain activity sensor attachable to a head of a sleeper. Brain activity signals from the sensor(s) are sent to a receiver at a local computer. The user, before retiring inputs a wake up time and attaches the sensor(s). The local computer sends brain activity signals to a remotely connected sleep analyzing server which analyzes the brain activity and identifies REM sleep periods and non-REM sleep periods. The labeled brain activity periods are returned to the local computer which waits for the wake up time. Then, the local computer sets an alarm time by adjusting the wake up time to coincide with a non-REM sleep period, if necessary and if possible.
