Patent number: 9880599Abstract: A mechanism is provided for throttling power utilized by a set of power consumption devices using priority-aware power capping. Responsive to unassigned power budget remaining in the overall power budget after a minimum power budget value has been assigned to the child device based on an associated priority of the child device, an additional power budget value equal to a remaining priority-based exposed power demand value of the child device is assigned to the child device in response to the remaining unassigned power budget being greater than or equal to the remaining priority-based demanded power value thereby forming a total power budget for the child device. Responsive to design limitations of power distribution equipment in the data processing system or contractual limits of the data processing system being reached, a throttling is implemented by each child device based on the total power budget assigned to the child device.Type: GrantFiled: October 12, 2016Date of Patent: January 30, 2018Assignee: International Business Machines CorporationInventors: Malcolm S.
