Abstract: Hierarchical Power Management (HPM) architecture considers the limits of scaling on a power management controller, the autonomy at each die, and provides a unified view of the package to a platform. At a simplest level, HPM architecture has a supervisor and one or more supervisee power management units (PMUs) that communicate via at least two different communication fabrics. Each PMU can behave as a supervisor for a number of supervisee PMUs in a particular domain. HPM addresses these needs for products that comprise a collection of dice with varying levels of power and thermal management capabilities and needs. HPM serves as a unified mechanism than can span collection of dice of varying capability and function, which together form a traditional system-on-chip (SoC). HPM provides a basis for managing power and thermals across a diverse set of dice.

Abstract: Methods and apparatus for balancing power between discrete components, such as processing units (e.g., CPUs) and accelerators in a compute node or platform. Power consumption of the compute platform is monitored to detect for conditions under which a threshold (e.g., power supply capacity threshold) is exceeded. In response, the operating frequencies of a processing unit and/or other platform components such as accelerators, are adjusted to reduce the power consumption of the platform to return below the threshold. Power limit biasing hints (scaling weights) are provided to platform components, along with a power violation index, which are used to adjust the operating frequencies of the platform components. Optionally, a processing unit can calculate the power violation index and the scaling weights and directly control the frequencies of itself and platform components. Embodiments of multi-socket platforms are also provided.
