Patent number: 9298249Abstract: A partition that is executed by multiple processing nodes. Each node includes multiple cores and each of the cores has a frequency that can be set. A first frequency range is provided to the cores. Each core, when executing the identified partition, sets its frequency within the first frequency range. Frequency metrics are gathered from the cores running the partition by the nodes. The gathered frequency metrics are received and analyzed by a hypervisor that determines a second frequency range to use for the partition, with the second frequency range being different from the first frequency range. The second frequency range is provided to the cores at the nodes executing the identified partition. When the cores execute the identified partition, they use a frequencies within the second frequency range.Type: GrantFiled: March 11, 2013Date of Patent: March 29, 2016Assignee: International Business Machines CorporationInventors: Andrew Geissler, Raymond J. Harrington, Hye-Young McCreary, Freeman Leigh Rawson, III, Malcolm Scott Ware

Patent number: 9146608Abstract: A method, computer program product, and apparatus for managing power management in a data processing system are presented. A core is activated and configured to operate at a frequency in response to a request to increase a processing capacity. A determination whether a use of power resulting from activating the core meets a policy for the use of the power is made. A set of parameters is adjusted to meet the policy for the use of power in response to a determination that the use of power does not meet the policy. A determination whether a number of operations performed by a set of cores is made. An indication that the request to increase the processing capacity is unavailable is made in response to the number of operations having not increased.Type: GrantFiled: December 12, 2013Date of Patent: September 29, 2015Assignee: International Business Machines CorporationInventors: Andreas Bieswanger, Andrew J.

Patent number: 8892916Abstract: Mechanisms for dynamically managing core pools are provided. The mechanisms measure the amount of a computational load on a computing device. One way of measuring the load may consist of executing a number of instructions, in a unit of time, with numerous cores of the computing device. The mechanisms compare the number of instructions executed with specific thresholds. Depending on whether the number of instructions is higher or lower than the thresholds, the computing devices may respond by activating and deactivating cores of the computing devices. By limiting execution of instructions of the computing device to a smaller number of cores and switching one or more cores to a lower power state, the devices may conserve power.Type: GrantFiled: August 6, 2008Date of Patent: November 18, 2014Assignee: International Business Machines CorporationInventors: Andreas Bieswanger, Andrew Geissler, Hye-Young McCreary, Freeman L.

Patent number: 8457805Abstract: A method, system, and computer usable program product for power distribution considering cooling nodes in a data processing environment. A power demand of a data processing environment is determined for a period. The data processing environment includes a set of computing nodes and cooling nodes. A determination is made that the power demand will exceed a limit on electrical power available to the data processing environment for the period if the computing nodes and the cooling nodes in the data processing environment are operated in a first configuration. A first amount of power is redistributed from a cooling node in the data processing environment to a computing node in the data processing environment such that a temperature related performance threshold of a subset of computing nodes is at least met.Type: GrantFiled: April 16, 2010Date of Patent: June 4, 2013Assignee: International Business Machines CorporationInventors: Andreas Bieswanger, Andrew Geissler, Raymond J Harrington, Hye-Young McCreary, Freeman Leigh Rawson, III, Malcolm Scott Ware

Patent number: 8032334Abstract: A system for identifying a subset of sensors to sample to reduce the frequency of sensor access. The system determines rise times and records values for the sensors in the system. A time criticality of the sensors is determined based on the rise times. The system processes the sensors by first creating sensor subsets based on one or more constraints on the sensors. The system monitors the values of the sensors in a sensor subset and flags a sensor when it makes a determination that, prior to a next scheduled sampling of the sensor subset, the value of a sensor in the monitored sensor subset will exceed a threshold constraint. The system moves those flagged sensors to a second sensor subset which complies with the sensor's constraints.Type: GrantFiled: December 22, 2008Date of Patent: October 4, 2011Assignee: International Business Machines CorporationInventors: Andreas Bieswanger, Michael S.

Patent number: 8028183Abstract: Disclosed is a computer implemented method, computer program product, and apparatus for determining a safe lower bound for a commonly powered data processing system. A power management module operates the data processing system using at least one nominal operating parameter during an exploration periodicity, with the at least one nominal operating parameter being clock speed. The power management module determines whether a calibration period is occurring. The power management module calibrates the data processing system up to a measurement interval duration expiration. The power management module may repeat operating the data processing system using the at least one nominal operating parameter.Type: GrantFiled: September 18, 2008Date of Patent: September 27, 2011Assignee: International Business Machines CorporationInventors: Andreas Bieswanger, Thomas M.

Patent number: 7908493Abstract: A mechanism is provided for unified management of power, performance, and thermals in computer systems. This mechanism incorporates elements to effectively address all aspects of managing computing systems in an integrated manner, instead of independently. The mechanism employs an infrastructure for real-time measurements feedback, an infrastructure for regulating system activity, component operating levels, and environmental control, a dedicated control structure for guaranteed response/preemptive action, and interaction and integration components. The mechanism provides interfaces for user-level interaction. The mechanism also employs methods to address power/thermal concerns at multiple timescales. In addition, the mechanism improves efficiency by adopting an integrated approach, rather than treating different aspects of the power/thermal problem as individual issues to be addressed in a piecemeal fashion.Type: GrantFiled: June 6, 2007Date of Patent: March 15, 2011Assignee: International Business Machines CorporationInventors: Andreas Bieswanger, Michael S.
