摘要:
Technologies to monitor and manage platform, device, processor and power characteristics throughout a system utilizing a remote entity such as controller node. By remotely monitoring and managing system operation and performance over time, future system performance requirements may be anticipated, allowing system parameters to be adjusted proactively in a more coordinated way. The controller node may monitor, control and predict traffic flows in the system and provide performance modification instructions to any of the computer nodes and a network switch to better optimize performance. The target systems collaborate with the controller node by respectively monitoring internal resources, such as resource availability and performance requirements to provide necessary resources for optimizing operating parameters of the system. The controller node may collect local system information for one or all of the computer nodes to dynamically steer traffic to a specific set of computers for processing to meet desired performance and power requirements.

Methods and systems may provide for determining whether a runtime disablement condition is met with respect to a sleep state and disabling the sleep state if the runtime disablement condition is met. Additionally, the sleep state may be enabled if a runtime reinstatement condition is met. In one example, determining whether the runtime disablement condition is met includes determining a false entry rate for the sleep state, and comparing the false entry rate to an energy-based threshold, wherein the sleep state is disabled if the false entry rate exceeds the energy-based threshold.

Systems and methods may provide for conducting a reward determination for a plurality of sleep states to obtain a plurality of reward determinations with respect to a device. In addition, a sleep state may be selected for the device from the plurality of sleep states based at least in part on the plurality of reward determinations. In one example, false entry and missed opportunity probabilities may be determined for stochastic interrupts, wherein the reward determination is conducted based at least in part on the false entry and missed opportunity probabilities.

Technologies for secure inter-virtual-machine shared memory communication include a computing device with hardware virtualization support. A virtual machine monitor (VMM) authenticates a view switch component of a target virtual machine. The VMM adds configures a secure memory view to access a shared memory segment. The shared memory segment may include memory pages of a source virtual machine or the VMM. The view switch component switches to the secure memory view without generating a virtual machine exit event, using the hardware virtualization support. The view switch component may switch to the secure memory view by modifying an extended page table (EPT) pointer. The target virtual machine accesses the shared memory segment via the secure memory view. The target virtual machine and the source virtual machine may coordinate ownership of memory pages using a secure view control structure stored in the shared memory segment. Other embodiments are described and claimed.

Methods and systems may provide for accumulating sensor-based information from a plurality of mobile devices and identifying context information in the sensor-based information, wherein the context information is relevant to a particular mobile device in the plurality of mobile devices. Additionally, an operational recommendation may be sent to the particular mobile device based on the context information. In one example, the operational recommendation identifies one or more of a power management action, a performance management action, a wireless interface selection and a wireless access point selection.

Methods and systems may provide for determining a status of a mobile platform, wherein the status indicates whether the mobile platform is stationary, and adapting a detection schedule of one or more location sensors on the mobile platform based at least in part on whether the mobile platform is stationary. Additionally, one or more location updates may be generated based at least in part on information from the one or more location sensors. In one example, a location request is received, wherein the detection schedule is adapted further based on quality of service (QoS) information associated with the location request, and wherein the one or more location updates are generated in response to the location request.

Methods and systems may provide for determining quality of service (QoS) information for a job associated with an application, and determining a condition prediction for a wireless channel of a mobile platform. Additionally, the job may be scheduled for communication over the wireless channel based at least in part on the QoS information and the condition prediction. In one example, scheduling the job includes imposing a delay in the communication if the condition prediction indicates that a throughput of the wireless channel is below a threshold and the delay complies with a latency constraint of the QoS information.

Methods, apparatus and systems for improved performance and energy efficiency of software-based routers. A software router running on a host computer system employing multiple Network Interface Controllers (NICs) maintains a routing table wherein packet flows are classified as managed flows (MFs) under which packets are received at and forwarded from the same NIC and unmanaged flows UFs under which packets are received at and forwarded from different NICs. Forwarding table data is employed by a NIC to facilitate packet identification and flow classification operations under which the NIC determines whether a received packet is an MF, UF, or an unclassified flow. Under various schemes, packet forwarding for MFs is handled by the software router architecture such that either only the packet header is copied into memory in the host or the entire packet forwarding is handled by the NIC.
