Abstract: Method and computer program product are provided to encode data for recording onto media whereby modulation and linear constraints from a concatenated code or product code are imposed. A first array of unencoded user data is generated. Each row is modulation encoded to enforce a first modulation constraint; the array is transformed into a second array which is transformed into a third array having predetermined empty locations in each column interleaved with the modulated data. A C2-parity byte is computed for at least some of the empty locations of the third array and a fourth array is generated. C1-parity symbols in each row are computed, generating a fifth array. A second modulation constraint is enforced on each C1-parity symbol in each row of the fifth array, generating a sixth array. The rows of the sixth array are assembled with header and sync fields for recording onto a recording media.

Abstract: An irrigation system includes a radio transmitter station that transmits weather prediction information to a geographic region that includes multiple geographic sub-regions. The weather prediction information includes a respective geographic sub-region code for each of the geographic sub-regions for which a weather forecast predicts rain within a predetermined time period. An irrigation apparatus in a particular sub-region activates to water a watering zone at a schedule time. However, if the irrigation apparatus receives the sub-region code for the particular sub-region where the irrigation apparatus is located, the irrigation apparatus does not immediately activate to water the watering zone in one embodiment. The transmitter station may transmit both program content and data content on a common radio frequency signal wherein the data content includes the weather prediction information.

Abstract: A data processing system includes multiple processors each having multiple processor cores. A core checkstop from a particular processor core indicates that a memory array associated with the particular core exhibits an error. In response to the core checkstop, the system migrates the workload of the particular processor core to another processor core. The system also removes the particular processor core from the current configuration of the system. In response to the core checkstop and error, the system initializes the particular processor core if the error is in a processor memory array associated with the particular core. The system then attempts correction of the error with array built-in self test (ABIST) circuitry. If the ABIST succeeds in correcting the error, the initialization of the particular processor core completes and the system returns the particular processor core to the current processor configuration.

Abstract: A method for processing a point-in-time copy of data associated with a logical storage volume where the data to be copied is stored in a striped or parallelized fashion across more than one physical source volume. The method includes receiving a point-in-time copy command concerning a logical volume and distributing the point-in-time copy command in-band to each of the physical source volumes containing a portion of the striped data. The method also includes establishing a point-in-time copy relationship between each physical source volume and one of a corresponding set of multiple physical target volumes. The method further includes copying the data stored on each physical source volume to the corresponding physical target volume. The in-band copy command and the striped data may be distributed over I/O channels between a server and the physical storage and processed sequentially.

Abstract: A method is provided for isolating errors which occur when code supplied by independent software vendors (ISV code) interacts with code supplied by a primary vendor (host code). Code suspected of containing ISV code with host code is executed. If the results are in error, the code is scanned and then compared with a master host code. Any differences are stored in a delta file, including locations in the host code where ISV code hooks into the host code. The code is then modified to by-pass the hooks to ISV code to generate a side-executable code and both codes are executed and the results are compared. A lack of substantial difference in the results is indicative that the ISV code adversely affects the host code while a difference between the results is indicative of an error in the modified code.

Abstract: A reversible thermal thickening grease for microelectronic packages, in which the grease contains filler particles; at least one polymer; and a binder; in which the filler particles are dispersed within the binder, in which one or more segments of the at least one polymer may be attached to the filler particles prior to dispersion in the binder, and in which the polymer collapses at temperatures below a Theta temperature and swells at temperatures above a Theta temperature. During the operation of a microelectronic package, grease pump-out and air proliferation are minimized with use of the reversible thermal thickening grease, while grease fluidity is retained under repetitive thermal stresses.

Abstract: System and computer program product are provided to configure a path between nodes through a fabric in a fibre channel storage area network (SAN). A node name is provided for a target node on the SAN and a port name is provided for each port in the target node. A relationship is established in a data structure between each port name and a slot in which each port is physically located in the target node. Prior to configuring a path between a source node and a port in the target node, the ports which are physically connected and logged in to the fabric are identified by port address. The port names corresponding to the port addresses are then identified. The port names are used to generate interface_ids of the ports corresponding to the physical slots in which the ports are located. A data structure is created to maintain the relationship between interface_ids and port names.

Abstract: An information handling system (IHS) employs operating system software to manage IHS resources. The operating system software manages software application programs as processes executing within the IHS. The processes run in foreground and background mode within the IHS. Processes running in foreground mode are subject to hang-up events with negative process output results, such as output data loss. In one embodiment, the operating system software supports a “no hang-up now” command for use with processes running in foreground mode. The “no hang-up now” command provides system users the ability to hang-up or log-out of an IHS terminal without negative effects on the current foreground process. A user may invoke the “no hang-up now” command after execution of the foreground process is already underway. The no hang-up command moves the foreground application to the background for continued execution. A signal handler program prevents termination of the background process until the process completes.

Abstract: An information handling system includes a processor with multiple hardware units that generate program application load, store, and I/O interface requests to system busses within the information handling system. The processor includes a resource allocation identifier (RAID) that links the processor hardware unit initiating a system bus request with a specific resource allocation group. The resource allocation group assigns a specific bandwidth allocation rate to the initiating processor. When a load, store, or I/O interface bus request reaches the I/O bus for execution, the resource allocation manager restricts the amount of bandwidth associated with each I/O request by assigning discrete amounts of bandwidth to each successive I/O requester. Successive stages of the instruction pipeline in the hardware unit contain the resource allocation identifiers (RAID) linked to the specific load, store, or I/O instruction.

Abstract: A method is provided for automatically applying named styles to existing documents including word processing documents. The existing document is scanned and parsed into style regions of uniform style. The style attributes of each uniform style region are identified, and these identified style attributes are used to create style groups containing style regions having identical or substantially identical style attributes. These style attributes can be expressed in set or vector form. Named styles are then associated with the identified style group by either comparing the style attributes of a given style group to the attributes of a pre-defined named style or by extracting a named style from the style group. Once associated with a named style, the style regions within a given style group can be modified to be consistent with the named style associated with the style group.

Abstract: The shortcomings of the prior art are overcome and additional advantages are provided through the provision of a self-centering nest for testing of microprocessor chip modules. The self-centering nest includes two slideable jaws disposed on a base diagonally opposite each other. Each jaw includes a jaw pin that is receptive in a carrier, such that when the jaw pins are received in the carrier, the jaws are in an open position. The self-centering nest includes a transfer mechanism for urging a microprocessor chip module from the carrier into the self-centering nest. The self-centering nest includes a plurality of springs, each spring having a first end connected to the first slideable jaw and a second end connected to the second slideable jaw. The springs cause the jaws to move toward each other capturing and centering the microprocessor chip module when the jaws are pulled away from the carrier releasing the jaw pins.

Abstract: Error correction coding is provided for codeword headers in a data tape format, such as a Linear Tape-Open, Generation 4 (LTO-4) data tape format. The data tape format defines a codeword quad as having first and second codeword headers interleaved with first and second codeword pairs, each codeword header comprising N bytes Ck=C0, C1, . . . , CN?2, CN?1 wherein K bytes C0-CK?1 of the first and second headers in a codeword quad differ such that if one is known the other can be inferred. Each header byte Ck of a codeword quad is redefined as comprising two interleaved (M/2)-bit nibbles, ek, ok. For each header, nibbles ek-eN?1 and nibbles ok-oN?1 are generated as a function of nibbles, e0-EK?1 and o0-oK?1, respectively. A codeword is assembled with the redefined headers the codeword quad is then recorded onto a recording medium.

Abstract: A client information handling system (IHS) connects to a network in a manner that provides transparent network connectivity. In one embodiment, the client IHS includes a polling application that monitors the network connection to determine if the client IHS exhibits a connected status or a disconnected status. An interceptor application in the client IHS permits transmission of a request for a network task from the client IHS if the client IHS currently exhibits a connected status. However, the interceptor application intercepts and stores a request for a network task if the client IHS currently exhibits a disconnected status. At a later time when the client IHS again exhibits a connected status, the interceptor application transmits the stored request over the network. In this manner, the user of the client IHS experiences transparent network connectivity and need not worry with respect to the network connection status of the client IHS at any particular point in time.

Abstract: The example embodiments disclose devices and methods to prevent silicide strapping of the Source/Drain to Body in semiconductor devices with S/D stressor. We provide isolation regions in the substrate and a gate structure over the substrate. We form recesses in the substrate adjacent to the gate structure with disposable spacers and adjacent to the isolation regions. We provide stressor regions filling the recesses. The stress region can have a pit adjacent the isolation regions. We form stressor spacers at least partially in the pit on the sidewalls of the stressor regions. We form silicide regions over the stressor regions. The spacer on the stressor regions sidewalls inhibit the formation of silicide at the stressor region edge during the silicide process, thus preventing silicide strapping of the Source/Drain to Body.
