Peak power package tracking

A method, comprising:

• sending, by a power manager comprising circuitry, a corresponding assigned power limit to each of a plurality of partitions that comprise circuitry;
• reducing, by a partition of the plurality of partitions subsequent to the partition receiving a first power limit from the power manager, power consumption responsive to a measurement of power consumption calculated by the partition exceeding the first power limit;
• reporting, to the power manager, data that corresponds to a period of time during which the partition reduced the power consumption;
• and
• sending, by the power manager, updated power limits to one or more of the plurality of partitions, the updated power limits being based at least in part on the data.

A computing system comprising:

• a processing unit comprising:
• a plurality of partitions, each configured to process one or more applications of a workload;
• a power manager configured to send a corresponding assigned power limit to each of the plurality of partitions;
• and
• wherein subsequent to a partition of the plurality of partitions receiving a first power limit from the power manager, the partition is configured to:
• calculate a measurement of power consumption;
• and
• perform steps to reduce power consumption responsive to the measurement of power consumption calculated by the partition exceeding the first power limit;
• and
• report, to the power manager, data that corresponds to a period of time during which the partition reduced the power consumption;
• and
• wherein the power manager is configured to send updated power limits to one or more of the plurality of partitions, the updated power limits being based at least in part on the data.
