Abstract: A cache coherent data processing system includes at least first and second coherency domains. In a first cache memory within the first coherency domain of the data processing system, a coherency state field associated with a storage location and an address tag is set to a first data-invalid coherency state that indicates that the address tag is valid and that the storage location does not contain valid data.

Abstract: The reassembly timer in a TCP/IP receiver is dynamically set to avoid data corruption on fast networks caused by IP identification wrap-around. A receiver independently sets the reassembly timer to a first reassembly time set by the user for fast networks or to a second reassembly timer set by the user for slow networks based on whether the receiver and sender are on the same subnet.

Abstract: The average EMR emissions of an electronic device may be reduced by implementing an electrically-active modulated termination. For example, the impedance may be continuously varied at one or more termination locations between two metal substructures to cause a like variation in the amplitude of each component of the EMR. According to one approach, cyclically varying the electrical impedance with a period of less than the time interval over which the EMR is measured will result in a reduction in the average measured EMR.

Abstract: A method, a system and a computer program product for selecting a primary controller for a server system based on the services offered by each controller. A primary controller designator (PCD) utility determines the relative importance of a controller based upon the services provided by the controller and the weighted importance assigned to these services. The PCD utility classifies the services provided by a system-controller according to the following: (1) the number of OS partitions a system-controller is able to communicate with; and (2) the number of hardware devices that a controller has access to. The importance of the services is determined by the host OS partition information and the degree of importance of a partition that utilizes/requires the particular service(s). The PCD utility designates a controller as a “Primary” if the designated “Primary” is capable of providing services that are required for the most important OS partitions, according to the classification of controller services.

Abstract: A computer implemented method, apparatus, and computer program product for generating a cohort using sensor and actuator input data. A signal is received from a set of sensors and actuators associated with a set of objects. In response to a determination that the signal is in an analog format, the signal is converted from the analog format into a digital format to form digital signal data. The digital signal data is processed to identify sensor and actuator attributes associated with the set of objects. The digital signal data comprises metadata describing the identified sensor and actuator attributes. A set of cohorts is generated using the sensor and actuator attributes, wherein each cohort in the set of cohorts comprises a subset of objects from the set of objects that share at least one sensor and actuator attribute in common.

Abstract: Load balancing of adapters on a multi-adapter node of a communications environment. A task executing on the node selects an adapter resource unit to be used as its primary port for communications. The selection is based on the task's identifier, and facilitates a balancing of the load among the adapter resource units. Using the task's identifier, an index is generated that is used to select a particular adapter resource unit from a list of adapter resource units assigned to the task. The generation of the index is efficient and predictable.

Abstract: A method and computer program product for improving storage efficiency for a digital video recorder. In one embodiment, a determination is made as to whether television programming is being presented on a high definition channel or a standard definition channel. The television programming is recorded using the digital video recorder responsive to determining that the television programming is being presented on a standard definition channel without making any resolution changes to the television programming. A determination is made as to whether the content of the television programming originates in high definition or standard definition. When the television programming originates in standard definition, a determination is made as to whether a corresponding standard definition channel is available. Responsive to determining the corresponding channel is available, the television programming is recorded in standard definition from the corresponding channel.

Responsive to the user selection to associate the second color with the first print cartridge position, a printer color association controller adjusts a reference to the first color in a print document to print in the second color through a second print cartridge in a second print cartridge position from among the plurality of print cartridge positions.

Abstract: Disclosed is a computer implemented method and apparatus for queuing I/O requests to a pending queue. The I/O device driver sets a maximum ordered queue length for an I/O device driver coupled to a storage device then receives an I/O request from an application. The I/O device driver determines whether the pending queue is sorted and responds to a determination that the pending queue is sorted, determining if queued I/O requests exceed the maximum ordered queue length. Responding to a determination that the pending queue exceeds the maximum ordered queue length, the I/O device driver adds the I/O request based on a high pointer, and points the high pointer to the I/O request.

Abstract: Methods, including service methods, articles of manufacture, systems, articles and programmable devices are provided for randomly setting a travel fee. A usage attribute of vehicle traffic travelling upon a toll thoroughfare is observed and compared to a threshold. As a function of comparing the attribute to the threshold, a plurality of different toll rates are randomly assigned to each of a plurality of vehicles, each of the vehicles either travelling upon the toll thoroughfare or potentially entering the toll thoroughfare. An occupant of a vehicle is notified of a toll rate randomly assigned, and fees or credits associated with travel by the occupant's vehicle are charged (levied or awarded) at the randomly assigned toll rate.

Abstract: An approach that obtains a feasible integer solution in a hierarchical circuit layout optimization is described. In one embodiment, a hierarchical circuit layout and ground rule files are received as input. Constraints in the hierarchical circuit layout are represented as an original integer linear programming problem. A relaxed linear programming problem is derived from the original integer linear programming problem by relaxing integer constraints and using relaxation variables on infeasible constraints. The relaxed linear programming problem is solved to obtain a linear programming solution. Variables are then clustered, and at least one variable from each cluster is rounded to an integer value according to the linear programming solution. Next, it is determined whether all the variables are rounded to integer values. Unrounded variables are iterated back through the deriving of the integer linear programming problem, solving of the relaxed linear programming problem, and rounding of a subset of variables.

Abstract: The present application provides an method and system for verifying a user's identity within a virtual world environment. The verification is to be in real-time and avoids the possibility of providing credential (e.g., biometric information) that were previously authentication, by sending to the user a time-sensitive challenge and requiring the user to provide the requested credentials (e.g., biometric information) within a predetermined time period. Therefore, the present invention is best positioned for environments where trusted identification of a user is needed online to facilitate secure transactions.
