Abstract: Useful work or services can be automated or otherwise facilitated or solutions to real world events developed by emulation of a real-world environment (which can contain objects representing virtual objects) with a virtual environment and generating a prioritized sequence of locations and associated tasks in accordance with resources related to the event in a virtual universe. Performance of the prioritized tasks at the prioritized locations is facilitated in the virtual universe by locally generating teleportation invitations corresponding to locations in the ordered sequence of locations.

Abstract: A method and system for providing quality of service guarantees for simultaneous multithreaded processors are disclosed. Hardware and operating system communicate with one another providing information relating to thread attributes for threads executing on processing elements. The operating system controls scheduling of the threads based at least partly on the information communicated and provides quality of service guarantees.

Abstract: A method and system for prefetching in computer system are provided. The method in one aspect includes using a prefetch engine to perform prefetch instructions and to translate unmapped data. Misses to address translations during the prefetch are handled and resolved. The method also includes storing the resolved translations in a respective cache translation table. A system for prefetching in one aspect includes a prefetch engine operable to receive instructions to prefetch data from the main memory. The prefetch engine is also operable to search cache address translation for prefetch data and perform address mapping translation, if the prefetch data is unmapped. The prefetch engine is further operable to prefetch the data and store the address mapping in one or more cache memory, if the data is unmapped.

Abstract: Color-based caching allows each cache line to be distinguished by a specific color, and enables the manipulation of cache behavior based upon the colors of the cache lines. When multiple threads are able to share a cache, effective cache management is critical to overall performance. Color-based caching provides an effective method to better utilize caches and avoid unnecessary cache thrashing and pollution. Hardware maintains color-based counters relative to the cache lines to monitor and obtain feedback on cache line events. These counters are utilized for cache coherence transactions in multiple processor systems.

Abstract: Enabling a Light-Weight Kernel (LWK) to run in a virtualized environment on a Full-Weight Kernel (FWK), in one aspect, may include replacing a FWK loader, e.g., FWK's dynamic library loader or linker, with a LWK library on a first computing entity for an application allocated to run on one or more second computing entities. The LWK library may be enabled to initialize the one or more second computing entities and associated memory allocated to run the application under the LWK library. The LWK library may be enabled to manage the one or more second computing entities and said associated memory and resources needed by the application.

Abstract: A vehicle control system to control operation of a vehicle includes a powertrain system operable according to a plurality of operating modes that drive the vehicle. A sensor is mounted to the vehicle to detect a quality of air surrounding the vehicle. A vehicle control module is configured to select an operating mode of the powertrain system. The operating mode is selected to reduce at least one emission exhausted from the vehicle that contributes to a low air quality measure by the sensor.

Abstract: A system for managing virtual meetings includes a processor operative to initiate participation with a first user interface in a first meeting, initiate participation with the first user interface in a second meeting, determining whether attention of a user is directed towards the first meeting or the second meeting, and configure the user interface such that the user interacts with meeting resources associated with the first meeting responsive to determining that the attention of the user is directed towards the first meeting.

Abstract: Memory Access Coloring provides architecture support that allows software to classify memory accesses into different congruence classes by specifying a color for each memory access operation. The color information is received and recorded by the underlying system with appropriate granularity. This allows hardware to monitor color-based cache monitoring information and provide such feedback to the software to enable various runtime optimizations. It also enables enforcement of different memory consistency models for memory regions with different colors at the same time.

Abstract: A device for copying performance counter data includes hardware path that connects a direct memory access (DMA) unit to a plurality of hardware performance counters and a memory device. Software prepares an injection packet for the DMA unit to perform copying, while the software can perform other tasks. In one aspect, the software that prepares the injection packet runs on a processing core other than the core that gathers the hardware performance counter data.

Abstract: Point-to-point intra-nodelet messaging support for nodelets on a single chip that obey MPI semantics may be provided. In one aspect, a local buffering mechanism is employed that obeys standard communication protocols for the network communications between the nodelets integrated in a single chip. Sending messages from one nodelet to another nodelet on the same chip may be performed not via the network, but by exchanging messages in the point-to-point messaging buckets between the nodelets. The messaging buckets need not be part of the memory system of the nodelets. Specialized hardware controllers may be used for moving data between the nodelets and each messaging bucket, and ensuring correct operation of the network protocol.

Abstract: A system and method for planning meeting attendance. The method includes receiving from a meeting requestor a request to schedule a proposed meeting at a time interval. The method also includes automatically calculating by a computer processor an attendance probability value for a potential attendee based, at least in part, on the potential attendee's location over time. The method further includes marking an electronic calendar of the meeting requestor with an indicia of the attendance probability value for the potential attendee. Additionally, the method may include automatically scheduling the proposed meeting if the attendance probability value is beyond an attendance probability threshold.

Abstract: A computing system and methods for memory management are presented. A memory or an I/O controller receives a write request where the data two be written is associated with an address. Hint information may be associated with the address and may relate to memory characteristics such as an historical, O/S direction, data priority, job priority, job importance, job category, memory type, I/O sender ID, latency, power, write cost, or read cost components. The memory controller may interrogate the hint information to determine where (e.g., what memory type or class) to store the associated data. Data is therefore efficiently stored within the system. The hint information may also be used to track post-write information and may be interrogated to determine if a data migration should occur and to which new memory type or class the data should be moved.
