摘要:
One embodiment of an apparatus includes a semiconductor chip having a processor and an on-die non-volatile storage resource. The on-die non-volatile storage may store different, appropriate performance related information for different configurations and usage cases of the processor for a same performance state of the processor.

A method and system for managing a power state of a processor are described herein. The method includes receiving, at the processor, a signal indicating that an interrupt is to be sent to the processor. The method also includes transitioning the processor from the deep idle state to the shallow idle state in response to receiving the signal and transitioning the processor from the shallow idle state to an active state in response to receiving the interrupt.

Systems and methods of operating a computing system may involve identifying a plurality of state values, wherein each state value corresponds to a computing thread associated with a processor. An average value can be determined for the plurality of state values, wherein a determination may be made as to whether to grant a frequency boost request based at least in part on the average value.

In one embodiment, a processor has multiple cores to execute threads. The processor further includes a power control logic to enable entry into a turbo mode based on a comparison between a threshold and value of a counter that stores a count of core power and performance combinations that identify turbo mode requests of at least one of the threads. In this way, turbo mode may be entered at a utilization level of the processor that provides for high power efficiency. Other embodiments are described and claimed.

Systems and methods of managing workloads provide for detecting a workload for a system having a first processor core with a first performance indicator and a second processor core with a second performance indicator. The workload is scheduled based on the first and second performance indicator settings. In one embodiment, a performance feasibility index is calculated for each core based on the core's frequency setting and utilization and the workload is assigned to the core associated with the highest index.

A method, system, and apparatus may route an interrupt to a first core of a plurality of cores of a multi-core system. If the first core is in an idle or low power state, or operating in a power state at or below a threshold power state, a core in a least idle state may be found. The interrupt may be rerouted to and processed by the core in the least idle state. Cores in a multi-core system may be rated based on for example, power states or other characteristics, and interrupts may be assigned based on these ratings. Other embodiments are described and claimed.
摘要:
Power consumption by a computer system may vary all the time based upon software and the workload. Facility such as data centers host multiple of computer systems. With continuous growing demand for power and cooling of computer systems, data centers face limitations on their ability to provide the power and cooling capability. These limitations are occasionally exasperated by problems in either power or cooling systems. The computer systems may have a method to maintain total power consumption below a set target level. An enterprise power and thermal manager, EPTM, may change this setting dynamically to improve efficiency of supporting power and cooling infrastructure. In addition, the EPTM may use this ability to improve performance, availability and to provide ability to implement various administrative policies.

Embodiments help dynamically configure the width of PCIe links and also determine how to best configure the appropriate link width. This helps avoid situations where PCIe links are almost always active even at very low traffic rates. Embodiments achieve these benefits based on, for example, run-time monitoring of bandwidth requirement for integrated and non-integrated ports located downstream for the PCIe controller. This provides power savings with little impact on performance. Other embodiments are discussed herein.
摘要:
A method and system for managing power consumption and performance of computing systems are described herein. The method includes monitoring an overall power consumption of the computing systems to determine whether the overall power consumption is above or below an overall power consumption limit, and monitoring a performance of each computing system to determine whether the performance is within a performance tolerance. The method further includes adjusting the power consumption limits for the computing systems or the performances of the computing systems such that the overall power consumption is below the overall power consumption limit and the performance of each computing system is within the performance tolerance.
