Abstract:
Technologies are generally described herein for handling interrupts within a multiprocessor computing system. Upon receiving an interrupt at the multiprocessor computing system, a priority level associated with an interrupt handler for the interrupt can be determined. Current task priority levels can he queried from one or more processors of the multiprocessor computing system. One of the processors can be assigned to execute the interrupt handler in response to the processor having a lowest current task priority level. Interrupt arbitration can schedule and communicate interrupt responses among processor cores in a multiprocessor computing system. Arbitration can query information about current task or thread priorities from a set of processor cores upon receiving an interrupt, The processor core that is currently idle or running the lowest priority task may be selected to service the interrupt.
Abstract:
Technologies are provided for function-targeted virtual machine switching. In some examples, function usage times on a virtual machine (VM) may be profiled by a virtual machine manager (VMM) and used to manage VM switching in order to preferentially switch VMs during specific targeted functions. The targeted functions and/or VM switching preferences may be adjusted over time in order to provide switching unpredictability, for example to frustrate side-channel attackers by forcing the attackers to gather data for much longer periods of time (e.g., weeks or months) if they want to detect or attack.

Techniques described herein generally include methods and systems related to the use of processors that include graphene-containing computing elements while minimizing or otherwise reducing the effects of high leakage energy associated with graphene computing elements. Furthermore, embodiments of the present disclosure provide systems and methods for scheduling instructions for processing by a chip multiprocessor that includes graphene-containing computing elements arranged in multiple processor groups.
Abstract:
Techniques described herein generally include methods and systems related to the selection of a combination of graphene an non-graphene transistors in an IC design. To reduce the increase in leakage energy caused by graphene transistors, selected non-graphene transistors may be replaced with graphene transistors in the IC design while other non-graphene transistors may be retained in the IC design. To limit the number of graphene transistors in the IC design, graphene transistors may replace non-graphene transistors primarily at locations in the IC design where significant delay benefit can be realized.
Abstract:
Technologies adapted for using acoustic pulses to diagnose skin conditions are disclosed. A series of acoustic pulses may be directed at a skin through the speaker of a device. Acoustic reflections may be received at a microphone. The reflections may be sampled and stored as echogram data. The echogram may be analyzed to identify potential skin conditions.
Abstract:
Technologies are generally described for systems, devices and methods effective to generate a message that may be sent to a social network. Power information from an electronic device may be detected by a power detector and received by a processor. For example, a power consumption profile of an appliance may be detected. The processor may classify the power information to produce descriptive data. For example, the processor may determine that an oven has been turned on for a period of time. The processor may generate the message by applying one or more rules to the descriptive data. For example, the processor may generate a message relating to consumption of dinner based on the determination that the oven has been turned on.
Abstract:
Technologies are generally described for systems, devices and methods effective to generate augmented image data. In some examples, a first device may receive first data from a second device. The first data may include data related to an image associated with the first device, such as an image of a user using the first device. The first device may apply an augmented reality skin to the first data to generate second data. The second data may relate to an augmented image associated with the first device. The first device may send the second data to the second device. The second device may then display the second data.
Abstract:
In a spatial modulation multiple-input-multiple-output (SM-MIMO) wireless communication system, multiple transmitting antennae and multiple receiving antennae may be utilized to respectively transmit and receive wireless signals for the communication. A selection of a combination of the multiple transmitting antennae may be configured to represent one or more binary digits in a signal sequence. The signal sequence may be produced at the receiving end without the knowledge of the selection of the combination of the multiple transmitting antennae.
Abstract:
Technologies are generally described for dynamically distributing a processing load. In some examples, a method performed under control of a server may include receiving information regarding load distribution from an end device and dynamically distributing a processing load between the server and the end device based at least in part on the information regarding load distribution.
Abstract:
Methods and systems for controlling traffic pollution are disclosed. An environmental score and a financial incentive based on the environmental score may be provided. A vehicle having a pollution recording unit may be provided. The pollution recording unit may be configured to provide an environmental score based on the pollution behavior of the vehicle. A financial incentive may be determined based on the environmental score at a processing device communicatively coupled to the pollution recording unit. The financial incentive may be provided to an operator of the vehicle.
