    Abstract: Systems, apparatuses, and methods for performing temperature-aware task scheduling and proactive power management. A SoC includes a plurality of processing units and a task queue storing pending tasks. The SoC calculates a thermal metric for each pending task to predict an amount of heat the pending task will generate. The SoC also determines a thermal gradient for each processing unit to predict a rate at which the processing unit's temperature will change when executing a task. The SoC also monitors a thermal margin of how far each processing unit is from reaching its thermal limit. The SoC minimizes non-uniform heat generation on the SoC by scheduling pending tasks from the task queue to the processing units based on the thermal metrics for the pending tasks, the thermal gradients of each processing unit, and the thermal margin available on each processing unit.

    Abstract: A method and apparatus for managing power in a thermal couple aware system includes determining a candidate configuration mapping based upon one or more criteria, the candidate configuration mapping being a mapping of performance for a candidate configuration of processor sockets in the thermal couple aware system. The candidate configuration mapping is evaluated by comparing the candidate configuration mapping to a stored configuration. If the evaluated candidate configuration mapping provides a better metric than the stored configuration, the stored configuration is updated with the evaluated candidate configuration mapping, and programming instructions are executed in accordance with the candidate configuration mapping if no other configuration mappings are to be determined.

    Abstract: Systems, apparatuses, and methods for performing real-time tracking of performance targets using dynamic compilation. A performance target is specified in a service level agreement. A dynamic compiler analyzes a software application executing in real-time and determine which high-level application metrics to track. The dynamic compiler then inserts instructions into the code to increment counters associated with the metrics. A power optimization unit then utilizes the counters to determine if the system is currently meeting the performance target. If the system is exceeding the performance target, then the power optimization unit reduces the power consumption of the system while still meeting the performance target.
