Abstract: A distributed data processing system executes multiple tasks within a parallel job, including a first local task on a local node and at least one task executing on a remote node, with a remote memory having real address (RA) locations mapped to one or more of the source effective addresses (EA) and destination EA of a data move operation initiated by a task executing on the local node. On initiation of the data move operation, remote asynchronous data move (RADM) logic identifies that the operation moves data to/from a first EA that is memory mapped to an RA of the remote memory. The local processor/RADM logic initiates a RADM operation that moves a copy of the data directly from/to the first remote memory by completing the RADM operation using the network interface cards (NICs) of the source and destination processing nodes, determined by accessing a data center for the node IDs of remote memory.

Abstract: Data recorded in a recording medium is encrypted with an encryption/decryption key, and the encryption/decryption key is encrypted with an encryption-only key. The encrypted encryption/decryption key is embedded in encrypted data. A decryption-only key the encryption/decryption key is embedded in a program for reading. The data and the program for reading are recorded in the recording medium. The data cannot be read without the program for reading. The program for reading cannot be used for recording other data even if it is copied.

Abstract: A system and method for implementing non-lethal chemical warfare against rampage shooters. A sound detection module detects a sound of a gunshot from at least one of a collection of sensors within a building. A sound location module determines a location of the gunshot by analyzing the sound. At least one emitter releases non-lethal chemical countermeasures from at least one at the location of the gunshot.

Abstract: A method within a data processing system by which a processor executes an asynchronous memory move (AMM) store (ST) instruction to complete a corresponding AMM operation in parallel with an ongoing (not yet completed), previously issued barrier operation. The processor receives the AMM ST instruction after executing the barrier operation (or SYNC instruction) and before the completion of the barrier operation or SYNC on the system fabric. The processor continues executing the AMM ST instruction, which performs a move in virtual address space and then triggers the generation of the AMM operation. The AMM operation proceeds while the barrier operation continues, independent of the processor. The processor stops further execution of all other memory access requests, excluding AMM ST instructions that are received after the barrier operation, but before completion of the barrier operation.

Abstract: A method is presented for representing emergent data in intelligent icons. The intelligent icons are visually coded to represent the emergent data. When logically linked, the visual coding of linked intelligent icons changes in accordance with how the intelligent icons are linked.

Abstract: A system and method for issuing load-dependent instructions in an issue queue in a processing unit. A load miss queue is provided. The load miss queue comprises a physical address field, an issue queue position field, a valid identifier field, a source identifier field, and a data type field. A load instruction that misses a first level cache is dispatched, and both the physical address field and the data type field are set. A load-dependent instruction is identified. In response to identifying the load-dependent instruction, each of the issue queue position field, valid identifier field, and source identifier field are set. If the issue queue position field refers to a flushed instruction, the valid identifier field is cleared. The load instruction is recycled, and a value of the valid identifier field is determined. The load-dependent instruction is then selected for issue on a next processing cycle independent of an age of the load-dependent instruction.

Abstract: An analog access circuit for characterizing chalcogenide memory cells is disclosed. The analog access circuit includes an analog access control module, an address and data control module, and an analog cell access and current monitoring module. The analog access control module selectively controls whether a normal memory access or an analog memory access should be performed on a specific chalcogenide memory cell. The address and data control module allows a normal memory access to the chalcogenide memory cell according to an input address. The analog cell access and current monitoring module performs an analog memory access to the chalcogenide memory cell according to the input address, and monitors a reference current from a sense amplifier associated with the chalcogenide memory cell.

Abstract: A method for migrating data between heterogeneous data storage devices within a storage area network is disclosed. A first virtualizer presents stored data as a first virtual disk, and then communicates a managed disk representation of the first virtual disk to a second virtualizer. After receiving the managed disk representation, the second virtualizer virtualizes the stored data from the managed disk representation as a second virtual disk. At such point, the stored data can be progressively migrated from the first virtualizer to the second virtualizer.

Abstract: A method, a system and a computer program product for mapping a client's request to perform boot and/or dump operations to a set of backing files which enable boot and dump operations in a data processing system. A Target Routing Driver (TRD) utility creates multiple Network Installation Management (NIM) objects and/or Network Dump Management (NDM) objects including (1) an Internet Small Computer Systems Interface (iSCSI) boot station and (2) an iSCSI dump collection point. The boot station exports a single iSCSI software (S/W) target from which a set of Diskless Servers obtain a boot image which enables a boot operation. The dump collection point exports a single iSCSI S/W target which is used by Diskless Servers as a dump location. The TRD utility uses the single target (exported from a particular NDM object type) to utilize the minimal resource allocation which allows listening on a single connection.

Abstract: A method, apparatus, and computer for identifying selection of a bad victim during victim selection at a cache and recovering from such bad victim selection without causing the system to crash or suspend forward progress of the victim selection process. Among the bad victim selection addressed are recovery from selection of a deleted member and recovery from use of LRU state bits that do not map to a member within the congruence class. When LRU victim selection logic generates an output vector identifying a victim, the output vector is checked to ensure that it is a valid vector (non-null) and that it is not pointing to a deleted member. When the output vector is not valid or points to a deleted member, the LRU victim selection logic is triggered to re-start the victim selection process.

Abstract: A method that enables automatic retrieval and transfer of bibliographical information whenever content is copied from a web page. During creation of a web page, the meta data defining each independent portion of the content is linked via paired comments or meta tags to bibliographical information associated with the content. When a person accesses the web site and copies the content from the site, the bibliographical information is automatically appended to the content. If that content is then pasted into a different document, e.g., within a word processing application, the bibliographical information is automatically transferred to a location for such information within the document. Also, if the content is saved, the bibliographical information is saved along with the content.

Abstract: A design structure for piggybacking multiple data tenures on a single data bus grant to achieve higher bus utilization is disclosed. In one embodiment of the design structure, a method in a computer-aided design system includes a source device sending a request for a bus grant to deliver data to a data bus connecting a source device and a destination device. The device receives the bus grant and logic within the device determines whether the bandwidth of the data bus allocated to the bus grant will be filled by the data. If the bandwidth of the data bus allocated to the bus grant will not be filled by the data, the device appends additional data to the first data and delivers the combined data to the data bus during the bus grant for the first data. When the bandwidth of the data bus allocated to the bus grant will be filled by the first data, the device delivers only the first data to the data bus during the bus grant.

Abstract: A data processing system includes a plurality of requestors and a memory controller for a system memory. In response to receiving from the requestor a read-type request targeting a memory block in the system memory, the memory controller protects the memory block from modification, and in response to an indication that the memory controller is responsible for servicing the read-type request, the memory controller transmits the memory block to the requestor. Prior to receipt of the memory block by the requestor, the memory controller ends protection of the memory block from modification, and the requestor begins protection of the memory block from modification. In response to receipt of the memory block, the requestor ends its protection of the memory block from modification.

Abstract: Disclosed are a method, a system and a computer program product for determining and reporting minterms to aid in implementing an engineering change order (ECO). A Minterm Tracing and Reporting (MTR) utility, which executes on a computer system, receives two or more timing points of an optimized netlist, where one or more of the two or more timing points are received from one or more of a user, a memory medium, and/or a network. For example, a timing point is a primary input, a primary output, or a latch point. After receiving the two or more timing points of the optimized netlist, the MTR utility determines two or more minterms of the optimized netlist. In determining the minterms, from one timing point to a next timing point: a polarity at the timing point may be determined, and a forward trace from the timing point to the next timing point is performed to determine the two or more minterms of the optimized netlist.

Abstract: A method and device for adaptively allocating reservation station entries to an instruction set with variable operands in a microprocessor. The device includes logic for determining free reservation station queue positions in a reservation station. The device allocates an issue queue to an instruction and writes the instruction into the issue queue as an issue queue entry. The device reads an operand corresponding to the instruction from a general purpose register and writes the operand into a reservation station using one of the free reservations station positions as a write address. The device writes each reservation station queue position corresponding to said instruction into said issue queue entry. When the instruction is ready for issue to an execution unit, the device reads out the instruction from the issue queue entry the reservation station queue positions to the execution unit.

Abstract: Metadata describing common Java classes is extracted and utilized to optimize a Java program's performance based on the code requirements of the application. Data mining techniques extract metadata and other information about different sets of JVM byte code written by multiple vendors to determine the design choices and optimizations made by each vendor in implementing their JVM. Then, byte code in a Java application being programmed is analyzed in comparison to each vendor's JVM metadata and information. Based upon the application's requirements (for example footprint, performance, etc.), recommendations are generated that yield a newly compiled rt.jar that combines the best practices of each vendor together or recommends a particular vendor's standard JVM that is best suited for the application.

Abstract: A method for fabricating selectively coupled optical waveguides on a substrate is disclosed. Initially, a first layer of waveguide material is deposited on a substrate. The first layer of waveguide material is then etched to form multiple level one waveguides and fill shapes. A dielectric layer is deposited on top of the level one waveguides and fill shapes. The surface profile of the dielectric layer deposition tracks the pattern density of the fill shapes. After the surface of the dielectric layer has been polished, a second layer of waveguide material is deposited on the substrate. At least one optically coupled waveguide structure, which is formed by a first level one waveguide and a first level two waveguide, is located adjacent to at least one non-optically coupled waveguide structure, which is formed by a second level one waveguide and a second level two waveguide.
