Methods and apparatus to provide holistic global performance and power management are described. In an embodiment, logic (e.g., coupled to each compute node of a plurality of compute nodes) causes determination of a policy for power and performance management across the plurality of compute nodes. The policy is coordinated across the plurality of compute nodes to manage a job to one or more objective functions, where the job includes a plurality of tasks that are to run concurrently on the plurality of compute nodes. Other embodiments are also disclosed and claimed.

Holistic global performance and power management

A scheme to improve performance of power-constrained computers, comprising a heterogeneous mix of compute elements, by dynamically reacting to changes in the switching capacitance that present workload induces in each heterogeneous compute element and learning the coefficients of a power-frequency model for each compute element for the present workload. At each time step, the scheme forecasts a maximum frequency that the compute element can run at without exceeding an input power limit for a given workload. The scheme rapidly re-learns coefficients of the power model and rapidly adapts the frequency as the workload's characteristics shift ensuring that compute elements run at the maximum frequency they can while not exceeding the input power limit.

Workload aware power limiting and multiple-input multiple-output control

Apparatus, systems, and methods provide an interface between a plurality of hardware resources of a node and a power manager. The interface is configured to define one or more resource groups to expose to the power manager for power measurement and control, assign the plurality of hardware resources to the one or more resource groups, and provide a power allowance to each resource group.

Systems and methods for synergistic software-hardware power budget management

An apparatus is provided which comprises: a controller to allocate, to a component, a resource budget selected from a plurality of quantization levels; and a circuitry to adaptively update the plurality of quantization levels.

Adaptive parameterization for maximum current protection

Various embodiments comprise prioritizing frequency allocations in thermally- or power-constrained computing devices. Computer elements may be assigned 'weights' based on their priorities. The computer elements with higher weights may receive higher frequency allocations to assure they receive priority in processing more quickly. The computer elements with lower weights may receive lower frequency allocations and suffer a slowdown in their processing. Elements with the same weight may be grouped together for the purpose of frequency allocation.

Hybrid prioritized resource allocation in thermally-or power-constrained computing devices

An apparatus system is provided which comprises: a first component and a second component; a first circuitry to assign the first component to a first group of components, and to assign the second component to a second group of components; and a second circuitry to assign a first maximum frequency limit to the first group of components, and to assign a second maximum frequency limit to the second group of components, wherein the first component and the second component are to respectively operate in accordance with the first maximum frequency limit and the second maximum frequency limit.

Dynamic maximum frequency limit for processing core groups

Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for Thermal Design Power (TDP) rebalancing among thermally-coupled processors and non-thermally-coupled processors, providing computing efficiency or homogeneity with respect to, including but not limited to, thermal requirements, power consumption, and processor operations. The TDP rebalancing may include implementing management circuitry and configuration control circuitry. Other embodiments may be described and claimed.

Techniques in performance and efficiency improvements of processors in a cooling system

Described herein are automated hierarchical feed-back driven control mechanisms and methods, including an apparatus comprising a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to receive a system operating characteristic guidance. The second circuitry may be operable to provide one or more manufacturing characteristics. The third circuitry may be operable to store one or more system operating characteristics based upon the system operating characteristic guidance and the one or more manufacturing characteristics.

System-wide network activity forecasting for performance improvement

Systems, apparatuses and methods may provide for determining, from a program comprising graphs of parallel operations and dependencies, an estimation of a droop risk associated with execution of the graphs by a load. A risk signal may be outputted based on the estimation. The risk signal may be associated with an adjustment in an output voltage of a voltage regulator and the output voltage is to be provided to the load.

Voltage droop mitigation technology in array processor cores

An apparatus is provided which comprises: a component; a voltage generator to supply load current to the component; first one or more circuitries to predict that the load current is to increase from a first time; and second one or more circuitries to, in anticipation of the increase in the load current from the first time, cause the component to execute first instructions during a time period that occurs prior to the first time.

Power noise injection to control rate of change of current

Systems, apparatuses and methods may provide for receiving indicator data associated with activity of a load. Additionally, an estimation of a rate of change of a current of the load with respect to time may be determined from the indicator data. Moreover, a boost signal may be selectively output to a voltage regulator when the estimation of the rate of change is greater than a first amount. The boost signal may be associated with an adjustment in an output voltage of the voltage regulator and the output voltage may be provided to the load.
