Abstract: An apparatus, a method and a computer program product are provided for conserving energy during functional mode of a processor by disabling the scan chain. By inserting logic gating into the scan chain it is possible to disable the scan chain during the processor's functional mode. During functional mode the scan out port of the latch bit in a scan chain toggles, which leads to unnecessary energy consumption. By gating scan control signals and the scan out port of a latch bit, the scan chain segment between latch bits can be disconnected. Therefore, the scan control signals can disable the scan chain during functional mode.

Abstract: Methods, systems, and media for remote control of a vehicle device and vehicle lockout notification are disclosed. Embodiments comprise a method of creating a secure bidirectional communication link between a remote access device and a central locking unit (CLU) of a vehicle, enabling the central locking unit to authenticate a user of the remote access device to manipulate a device of the vehicle. In some embodiments, the CLU may wait for an access attempt from a mobile device. In other embodiments, the CLU monitor vehicle conditions, detect a lockout condition, and alert the user before authenticating and granting vehicle access. Embodiments utilize private and shared key encryption methods to facilitate securely passing an access code between the CLU and the remote access device. Some embodiments authenticate the user by voice verification, while other embodiments may use personal identification numbers.

Abstract: A design structure for a hybrid phase locked loop (PLL) circuit that obtains stabilized dynamic response and independent adjustment of damping factor and loop bandwidth is provided. The hybrid PLL circuit of the illustrative embodiments includes the resistance/capacitance (RC) filter elements of a conventional RC PLL and the feed-forward path from the output of the phase frequency detector to the voltage controlled oscillator (VCO). The hybrid PLL essentially enhances the performance of the conventional feed-forward PLL by providing the RC filter whose components can be weighted to provide a dynamic response that is significantly less sensitive to parameter variation and which allows loop bandwidth optimization without sacrificing damping.

Abstract: A multiplier engine that reduces the size of the circuitry used to provide the multiplier engine, as well as increases the speed at which the multiplication algorithm is performed, are provided. The illustrative embodiments may comprise a M*8 multiplication engine having one or more 4:2 compressors that comprise only two full adders, as opposed to the three full adders in the known 5:2 compressor based architecture. The 4:2 compressors are able to achieve the same operation as the known 5:2 compressor based architecture by virtue of using the unused bits in a least significant portion of the partial product inputs to store the negate bit values. Moreover, a negate bit value that is not fused with the partial product inputs may be input to the 4:2 compressors for a bit 0 position.

Abstract: Processing a multiple table query includes: determining if any tables in the query require materialization; for each table in the query that requires materialization, deriving at least one join predicate on a join column; determining if any tables earlier in a join sequence for the query has same join predicates; and applying the at least one derived join predicate to an earlier table in the join sequence, if there is at least one table earlier in the join sequence that has the same join predicate. This significantly reduces the number of rows that are joined before arriving at the final result.

Abstract: Generally speaking, systems, methods and media for detection and network reconfiguration upon changes in dynamic host configuration protocol (DHCP) IP addresses are disclosed. Embodiments of a method may include setting a renew time and a rebind time of a DHCP configuration and establishing an IP address with a first DHCP server. Embodiments may also include, after passage of the renew time, transmitting a renew request to the first DHCP server at its IP address and, in response to failure to receive an acknowledgement message from the first DHCP server, determining if the first DHCP server IP address is still valid. Embodiments may also include, in response to determining that the first DHCP server IP address is not still valid, retrieving a second, different DHCP server IP address from a network change event signal and configuring a network adapter based on the second DHCP server IP address.

Abstract: A pipeline processor has circuits to detect the presence of a register access instruction in an issue stage of the pipeline. A load-miss occurring at a later stage may cause the register access instruction to be marked with an associated bit. The register access instruction progresses down the pipeline and when the flush stage is reached, the processor checks the associated bit and flushes the register access instruction.

Abstract: Mechanisms for thresholding system power loss notifications in a data processing system are provided. Power loss detection modules are provided in a data processing system having one or more data processing devices, such as blades in an IBM BladeCenter® chassis. The power loss detection modules detect the type of infrastructure of the data processing system, a position of a corresponding data processing device within the data processing system, and a capability of the data processing system to provide power during a power loss scenario. The detection module detects various inputs identifying these types of data processing system and power system characteristics and provides logic for defining a set of behaviors during a power loss scenario, e.g., behaviors for sending system notifications of imminent power loss. The detection of the various inputs and the defining of a set of behaviors may be performed statically and/or dynamically.

The embodiment may include detecting applications signaling a user for attention and displaying a list of active applications of the plurality of computing devices in response to a command from the user. The displaying may include giving priority to the applications signaling a user for attention.

Abstract: Automigration mechanisms having fuzzy-logic based automigration control mechanisms for implementing control schemes controlling start, stop and/or bandwidth of the automigration process are provided. The automigration control mechanisms read, into a memory of an automigration controller circuit, configuration parameters characterizing the hardware and software properties of the source storage and target storage, and that of the network connection between them. The mechanisms further derive fuzzy variables from the values of the input variables and of the configuration parameters. The mechanisms further provide a predetermined fuzzy function with the fuzzy variables, where the fuzzy function reflects the exhaustion level of the source executing the fuzzy function yielding a fuzzy result value. The mechanisms apply the fuzzy result value to one of the control schemes, yielding a control result. The mechanisms control the start, stop, and/or bandwidth of the automigration of data by aid of the control result.

Abstract: Mechanisms for communicating with a processor event facility are provided. The mechanisms make use of a channel interface as the primary mechanism for communicating with the processor event facility. The channel interface provides channels for communicating with processor facilities, memory flow control facilities, machine state registers, and external processor interrupt facilities, for example. These channels may be designated as blocking or non-blocking. With blocking channels, when no data is available to be read from the corresponding registers, or there is no space available to write to the corresponding registers, the processor is placed in a low power “stall” state. The processor is automatically awakened, via communication across the blocking channel, when data becomes available or space is freed. Thus, the channels of the present invention permit the processor to stay in a low power state.

Abstract: A system and method for providing sticky applications are provided. A “sticky application” is an operating system (OS) level application that has the ability to “stick” to web applications and become a part of the web page on which the web application is running. While the sticky application is stuck to the web application, it behaves as if it were a web application with respect to the user. When the user chooses to “unstick” the application, it will return to behaving as an OS level application. The sticky application imitates being a web-based application instead of an operating system level application while stuck. This imitation involves the sticky application being placed on pixel coordinates within a web page of the web application and the sticky application remaining in the pixel coordinates within the web page where it is placed even when a user modifies the representation of the web page.

Abstract: Markup language node level hash join operations for evaluating a query language query are performed. The markup language node level hash join mechanism, i.e. the “XHashJoin” operator, is a multi-way join operator that uses two hash tables, BUILD and PROBE, to intersect document nodes from multiple index scans and to buffer intermediate query results. The BUILD hash table stores document nodes matching the predicates of a query, and buffers document nodes satisfying extraction nodes, of each portion of the query up to a current portion of the query being evaluated. The BUILD hash table and the PROBE hash table are switched at each portion of the query being evaluated. Query results are generated by linking document nodes buffered in the BUILD hash table based on the semantics of each extraction node.

Abstract: Mechanisms for providing a cluster-wide system clock in a multi-tiered full graph (MTFG) interconnect architecture are provided. Heartbeat signals transmitted by each of the processor chips in the computing cluster are synchronized. Internal system clock signals are generated in each of the processor chips based on the synchronized heartbeat signals. As a result, the internal system clock signals of each of the processor chips are synchronized since the heartbeat signals, that are the basis for the internal system clock signals, are synchronized. Mechanisms are provided for performing such synchronization using direct couplings of processor chips within the same processor book, different processor books in the same supernode, and different processor books in different supernodes of the MTFG interconnect architecture.

Abstract: A mechanism for uninterrupted booting of a client computer coupled to a pre-boot execution server computer over a network is provided. The client computer has at least two or more network interface cards. A network bootstrap file is downloaded from the server computer to the client computer. The network bootstrap file is configured to monitor the booting process of the client computer. On detection that the network interface card has failed to transmit or receive packets, the network bootstrap file is configured to switch over to the next available network interface card on the client system thereby providing uninterrupted execution of the booting process.

Abstract: Mechanisms for generating a worst case current waveform for testing of integrated circuit devices are provided. Architectural analysis of an integrated circuit device is first performed to determine an initial worst case power workload to be applied to the integrated circuit device. Thereafter, the derived worst case power workload is applied to a model and is simulated to generate a worst case current waveform that is input to an electrical model of the integrated circuit device to generate a worst case noise budget value. The worst case noise budget value is then compared to measured noise from application of the worst case power workload to a hardware implemented integrated circuit device. The worst case current waveform may be selected for future testing of integrated circuit devices or modifications to the simulation models may be performed and the process repeated based on the results of the comparison.
