摘要： Power saving strategies are presented for use in communication systems, networks, and devices. In at least one embodiment, a power saving probe request is sent from a first entity to a second entity to request information on available power saving capabilities of the second entity. The first entity may then receive a power saving probe response from the second entity that includes information on available power saving capabilities of the second entity. The first entity may then negotiate with the second entity for provision of at least one power saving service chosen from the available power saving capabilities. In another embodiment, a first entity may send power saving probe requests to a number of second entities to request information on available power saving capabilities of the second entities. The first entity may then receive power saving probe responses from the second entities that each include information on available power saving capabilities of a corresponding second entity. The first entity may then select a second entity with which to communicate based on information within the received power saving probe responses.

摘要： Apparatus and methods implementing a hardware queue management device for reducing inter-core data transfer overhead by offloading request management and data coherency tasks from the CPU cores. The apparatus include multi-core processors, a shared L3 or last-level cache (“LLC”), and a hardware queue management device to receive, store, and process inter-core data transfer requests. The hardware queue management device further comprises a resource management system to control the rate in which the cores may submit requests to reduce core stalls and dropped requests. Additionally, software instructions are introduced to optimize communication between the cores and the queue management device.

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.

摘要： Techniques are described for determining a temporary latency tolerance report (tLTR) value. A processing unit has to respond to a device interrupt within a duration specified by tLTR to ensure no incoming data is lost due to device buffer overflow. The tLTR value can be used to prevent the processing unit from entering too deep a sleep state when a device driver anticipates multiple sequential interrupts for a transaction.

摘要： A power management unit (PMU) may determine an optimal power saving state using a break-even period of a power saving state and an expected idle duration based on a first policy. The PMU may determine the optimal power saving state using a first break even period and actual idle duration based on a second policy. The break-even period may equal a minimum time a computer system should remain in a power saving state to compensate for the power consumed by the system to enter and exit that power saving state. The expected idle time duration is determined as an average of idle duration and a recent sample of idle duration. The actual idle duration is the difference of a first and second time point that represents entry and exit points to and from the power saving state. The PMU may transition the system to the optimal power saving state.
摘要翻译：功率管理单元（PMU）可以使用基于第一策略的功率节省状态和预期空闲持续时间的均衡周期来确定最佳省电状态。 PMU可以基于第二策略来确定使用第一中断均衡周期和实际空闲持续时间的最佳省电状态。休眠时间可以等于计算机系统应该保持在节电状态的最小时间，以补偿系统进入和退出该省电状态所消耗的功率。预期的空闲时间长度被确定为空闲持续时间的平均值和最近的空闲持续时间采样。实际空闲持续时间是表示进出节点状态的第一和第二时间点的差异。 PMU可以将系统转换到最佳省电状态。
