Mechanism of efficient intra-die collective processing across the nodelets with separate shared memory coherency domains is provided. An integrated circuit die may include a hardware collective unit implemented on the integrated circuit die. A plurality of cores on the integrated circuit die is grouped into a plurality of shared memory coherence domains. Each of the plurality of shared memory coherence domains is connected to the collective unit for performing collective operations between the plurality of shared memory coherence domains.

Performing a series of successive synchronizing operations by a core on data shared by a plurality of cores may include a first core indicating an upcoming synchronizing operation on shared data. A second memory layer stores the shared data and tracks the first core's ownership of the shared data. The second memory layer is shared via coherency operations among the first core and one or more second cores. The first core may perform one or more synchronization operations on the shared data without requiring interaction from the second memory layer.

A device for supporting hardware enabled performance counters with support for context switching include a plurality of performance counters operable to collect information associated with one or more computer system related activities, a first register operable to store a memory address, a second register operable to store a mode indication, and a state machine operable to read the second register and cause the plurality of performance counters to copy the information to memory area indicated by the memory address based on the mode indication.

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 a cache and avoid unnecessary cache thrashing and/or pollution. The color based caching can be monitored to improve memory performance and guarantee Quality-Of-Service of cache utilization.

A system, method and computer program product for monitoring availability of end user devices needed for performing tasks. The system comprises a first network including one or more devices associated with an end user, at least one device adapted for communicating with a service provider over a second network, the service provider providing network-based services in the system. The system includes a memory storage device for maintaining information of tasks associated with an end user, the information including recommended end-user devices adapted to perform the tasks, the information being accessible to at least one end-user device. At least one end-user device detects non-availability or performance deficiencies of any end-user device required in performing end-user tasks, and communicates with the service provider for invoking network-based services to facilitate correcting non-availability of any end-user device. Such a system, method and computer program product enables students to receive these reminders and alerts, to order the necessary upgrades from suppliers via web services, and to monitor delivery from a single user interface provided on one of their devices.

In the context of screens, windows and like media, arrangements for automatically detecting when a recipient has entered or left a public setting so that privacy configuration changes can be automatically invoked. Also broadly contemplated herein is an arrangement for selectively displaying messages on the recipient's screen but deferring the messages from being visible on a remote hardware device or software display which is publicly visible. Furthermore, there is broadly contemplated herein a secure arrangement for revealing and responding to deferred messages. More generally, there is broadly contemplated herein a new approach to the provision of application notifications and to alarm control during a desktop screen sharing mode, based on the automatic detection of a screen sharing state and on notifying registered applications of the screen sharing in a unified, consistent manner.

A method comprising receiving control information at a first processing element from a second processing element, synchronizing objects within a shared global memory space of the first processing element with a shared global memory space of a second processing element in response to receiving the control information and generating a completion event indicating the first processing element has been synchronized with the second processing element.

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.
摘要:
A system for planning meeting attendance. The system includes a computer processor configured to receive from a meeting requestor a request to schedule a proposed meeting at a time interval. The computer processor is further configured to calculate an attendance probability value for a potential attendee based, at least in part, on the potential attendee's location over time. Additionally, the computer processor is configured to mark an electronic calendar of the meeting requestor with an indicia of the attendance probability value for the potential attendee. The computer processor may also be configured to automatically schedule the proposed meeting if the attendance probability value is beyond an attendance probability threshold.
