| 20100095137 | Dynamic Frequency And Voltage Scaling For A Computer Processor - Dynamic frequency and voltage scaling for a computer processor, including retrieving information specifying a nominal operating point of frequency and voltage and an operating range of frequency and voltage for the processor; creating, by the power management module dynamically at run time in dependence upon the retrieved information, a table of frequency, voltage pairs, each pair specifying an operating point of frequency and voltage for the processor, each pair disposed upon a line drawn in frequency-voltage space through the nominal operating point between the minimum operating point and the maximum operating point, the distance between each pair defined in dependence upon a minimum change in power supply voltage supported by the power supply; and selecting and applying, by the power management module from the table, an operating voltage and frequency for the processor in dependence upon current operating conditions of the processor. | 04-15-2010 |

| 20080307134 | I2C bus interface and protocol for thermal and power management support - A method, apparatus and computer instructions are provided for controlling communications between controller devices over an I | 12-11-2008 |
| 20080307238 | System for Unified Management of Power, Performance, and Thermals in Computer Systems - A system is provided for unified management of power, performance, and thermals in computer systems. This system incorporates elements to effectively address all aspects of managing computing systems in an integrated manner, instead of independently. The system 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 system provides interfaces for user-level interaction. The system also employs methods to address power/thermal concerns at multiple timescales. In addition, the system 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. | 12-11-2008 |
| 20090063666 | Network and Method for the Configuration Thereof - A method and corresponding apparatus is provided for determining the location of a configuration server being connected to a totally symmetric network infrastructure that does not exhibit any symmetry breakers on network level. The configuration server reaches a decision to determine its network-wide unique configuration in order to be able to serve controllers. This decision depends on the plug position of the configuration server under consideration and the assumption of plugging rules governing a “good” network infrastructure. The controllers periodically send network packets that will be marked if they traverse specific connection elements in the network. The origin and the path of a network packet can be determined. The decision making is based on a majority function based on the packets received by the configuration server. If a decision cannot be made, then errors in the cabling structure can be detected. | 03-05-2009 |
| 20090099817 | Sensor Subset Selection for Reduced Bandwidth and Computation Requirements - 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. | 04-16-2009 |
| 20100037038 | Dynamic Core Pool Management - Embodiments that dynamically manage core pools are disclosed. Various embodiments involve measuring 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. These embodiments may 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. | 02-11-2010 |
| 20100070787 | POWER CAP LOWER BOUND EXPLORATION IN A SERVER ENVIRONMENT - 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. | 03-18-2010 |

| 20090307685 | Method, Arrangement, Computer Program Product and Data Processing Program for Deploying a Software Service - Deploying a software service. A defined software service offering is selected from a plurality of defined software service offerings. An instantiation order for deploying the selected defined software service offering on a corresponding computer system is generated. Each defined software service offering comprises a software service definition and at least one defined software policy. One selected from the group consisting of the software service definition, the software policy, and a combination thereof, provides a hardware configuration for the software service, a software configuration for the software service, and a managing policy for the software service. The instantiation order of the software service for execution on the computer system is created based on the hardware configuration, the software configuration and the managing policy. | 12-10-2009 |
| 20110109378 | Method and Device For Supplying Power to a Microelectronic Chip - A method and a device for supplying power to one or more microelectronic chips. The method comprises the steps of reading a process characteristic parameter associated with the chip from a non-volatile storage, wherein the process characteristic parameter represents a manufacturing process characteristics of the chip; determining a minimal voltage (VDD_min) based on the parameter; and supplying electric power to the chip ( | 05-12-2011 |

| 20110257802 | POWER DISTRIBUTION CONSIDERING COOLING NODES - 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. | 10-20-2011 |
