Abstract: A system and method for automatically simulating the affect of a plurality of factors on the cost of goods sold (COGS) resulting from changes in the allocation of goods to be sold in a plurality of predetermined markets. A predetermined plurality of markets are defined, each of which is allocated a default percentage of total goods to be sold. A plurality of production sites are then defined, their associated cost factors determined, their respective output assigned to predetermined markets, and the weighted, average unit COGS for each market is then calculated. A defined market is then selected for sensitivity simulation and its associated sales allocation is iteratively decremented by a predetermined percentage for reallocation to other markets. Each market's weighted, average unit cost is recalculated after each iteration, and once reallocation is completed, the global, average unit COGS is calculated.

Abstract: A system and method are disclosed for managing the connectivity of a mobile device to a plurality of network connectivity locations. A mobile device comprising a network connectivity manager accesses a repository of predetermined network connectivity management information stored on a network host. The network connectivity manager uses a first predetermined subset of the information to discover the presence of a first network and then manages connectivity between the mobile device and the first discovered network. A second predetermined subset of information is then used to discover the presence of a second network. The network connectivity manager then transfers the mobile device's connectivity from the first network to the second network. Transfer of connectivity is dependent upon successful submission and acceptance of predetermined user credentials and each network's compliance with predetermined connectivity policies.

The first IMS user selects the IMS user identifier of the second IMS user, followed by selection of a target virtual world and a virtual world identifier. Once completed, the invitation is sent the IMS user identifier of the second IMS user, who receives the invitation and signifies their acceptance or declination. If accepted, the cross-referenced virtual world user identifiers of the first and second IMS users are used to log them into the agreed-upon virtual world venue and initiate a virtual world session.

Abstract: Information handling system network addresses are managed to support a consistent MAC address for iSCSI and fiber channel host bus adapter. For example, a management controller retrieves a MAC address from persistent memory, such as a network location, and assigns the MAC address to a non-persistent memory of a predetermined information handling system network component so that the MAC address remains consistent even if the network component is replaced. For example, an offload engine that supports network communications with iSCSI receives a MAC address from a network location and applies the MAC address for use by a host bus adapter. Alternatively, an offload engine supports Fiber Channel with World Wide Name or World Wide Identifier address assignments.

In addition, the appliance may separately track the transaction activities of end users who receive recommendation messages and the transaction activities of end users who do not receive recommendation messages, so that a comparison of the effectiveness of the recommendations may efficiently be demonstrated without requiring any modification to the code or architecture of the web server.

Abstract: A video processing apparatus and methodology use a combination of a processor and a video decoding hardware block to decode video data by using a reference block cache memory to perform motion compensation decode operations in the video decoding hardware block. To improve the cache hit rate, each memory access for required reference block(s) is used to fetch one or more additional reference blocks which can be used to improve the cache hit rate with future motion compensation operations. Speculative fetch control logic selects the additional reference blocks by using a frequency history table to accumulate compared motion vector information for a current motion compensation block with motion vector information from previously processed motion compensation blocks.

Abstract: A method, system and program are provided for dynamically reconfiguring a pipelined processor to operate with reduced power consumption without reducing existing performance. By monitoring or detecting the performance of individual units or stages in the processor as they execute a given workload, each stage may use high-performance circuitry until such time as a drop in the throughput performance is detected, at which point the stages are reconfigured to use lower-performance circuitry so as to meet the reduced performance throughput requirements using less power. By configuring the processor to back off from high-performance designs to low-performance designs to meet the detected performance characteristics of the executing workload warrant, power dissipation may be optimized.

Abstract: A method and apparatus are described for fabricating an ultra low-k interconnect structure by depositing and curing a first via layer (43) of ultra low dielectric constant (ULK) material, depositing a second uncured trench layer (51) of the same ULK material, selectively etching a via opening (62) and trench opening (72) with a dual damascene etch process which uses a trench etch end point signal from the chemical differences between uncured trench layer (51) and the underlying cured via layer (43), and then curing the second trench layer (83) before forming an interconnect structure (91) by filling the trench opening (72) and via opening (62) with an interconnection material so that there is no additional interface or higher dielectric constant material left behind.

Abstract: Network addresses are dynamically allocated to blade information handling systems supported by a blade chassis having plural blade slots. A network address seed stored in memory associated with the blade chassis is retrieved by a management controller of a blade information handling system and applied by a network address generator to local network address information to generate a network address. The generated network address is applied by the management controller to a network component of the blade information handling system to establish communications over a network. For example, a WWN generated from a blade chassis seed address provides a blade information handling system host bus adapter access to a storage area network for boot from SAN support for the blade information handling system.

Abstract: Configuration spaces facilitate the useful presentation of data, particularly configuration data used for representing configured products. Products include features and common features can be grouped by families. For example, an automobile can include a transmission family. The transmission family could include features such as automatic transmission and 4-speed manual transmission. Configuration spaces can be achieved by consolidating selected data without loosing useful information. The degree of consolidation achieved can be significant enough to permit display of data using conventional display technology. Configuration spaces break down the “universe” of possible configurations into constituent spaces defined by groups of rules for a selected feature. Common dependencies between the selected feature and related features can be consolidated to produce a more minimal form of the data used for representing the selected features and related features.
