摘要： Technologies for supporting concurrency of a flow lookup table at a network device. The flow lookup table includes a plurality of candidate buckets that each includes one or more entries. The network device includes a flow lookup table write module configured to perform a displacement operation of a key/value pair to move the key/value pair from one bucket to another bucket via an atomic instruction and increment a version counter associated with the buckets affected by the displacement operation. The network device additionally includes a flow lookup table read module to check the version counters during a lookup operation on the flow lookup table to determine whether a displacement operation is affecting the presently read value of the buckets. Other embodiments are described herein and claimed.

摘要： Technologies for modular forwarding table scalability of a software cluster switch includes a plurality of computing nodes. Each of the plurality of computing nodes includes a global partition table (GPT) to determine an egress computing node for a network packet received at an ingress computing node of the software cluster switch based on a flow identifier of the network packet. The GPT includes a set mapping index that corresponds to a result of a hash function applied to the flow identifier and a hash function index that identifies a hash function of a hash function family whose output results in a node identifier that corresponds to the egress computing node to which the ingress computing node forwards the network packet. Other embodiments are described herein and claimed.

摘要： Elements of a graphical user interface, such as a virtual keypad, can have display characteristics adjusted based upon aspects such as a relative hand or finger position of a user. In one example, the transparency of a keypad used to enter text on a portable computing device can be adjusted based on the distance of a user's hand, such that the user can still view content displayed through the interface. A user can also select elements, such as text fields for text entry, by adjusting a relative position of the user's hand and performing a selection gesture or other such action. Various types of functionality can be activated in response to a selection gesture, such as to display a keypad of an appropriate transparency.

摘要： As mobile handsets are typically much slower than desktops for processing intensive applications, and as XSL-based XML document transformations (or XSLT) are processing intensive, such transformations are costly on mobile devices both because of execution time and energy consumption. While other processing intensive applications, such as voice communication and graphics rendering, have exploited options in the design of mobile processor architecture, similar methodologies have not been applied to XSLT processing. A method for parallelizing XSLT processing on devices with multiple processors is therefore devised. The method divides XSLT processing into separately schedulable subtasks, synchronizes these subtasks, and schedules such subtasks on multiple processors for improved time and energy efficiency.
