摘要： A data processing system includes a power supply, a plurality of processors wherein each processor is separately powerable by the power supply under operating system control. The operating system determines periodically a measure of system utilization and controls the switches to alter the number of active (powered) processors where the number of active processors reflects the measured system utilization and a set of utilization threshold values. System utilization may be based on the number of active tasks. The utilization thresholds preferably include a maximum threshold and a minimum threshold. A measured utilization exceeding the maximum threshold causes an increase in the number of active processors while utilization less than the minimum threshold causes a decrease in the number of active processors. The utilization thresholds may be determined from threshold factors that reflect time and date information, quality of service information, or a weighted average of historical utilization values.

摘要： A power management system schedules the voltage and frequency of processors in a data processing system based on two criteria. The first criterion is a prediction of the performance that the work currently running on the processor will experience at the different frequencies that are available. The second criterion is a system-wide constraint on the total power budget allocated to processors. Based on these criteria, low-level code sets the frequency and voltage of the processors in the system to match what the operating system is currently running on them.

摘要： 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.

摘要： A weighted event counting system and method for processor performance measurements provides low latency and low error performance measurement capability. A weighted performance counter accumulates a performance count according to a plurality of event signals provided from functional units in the processor. Differing weights are applied to the event signals in according to the correlation between each event with processor performance. The weights may be provided from programmable registers, so that the weights can be adjusted under program control. The event signals may be combined to reduce the bit-width of the set of event signal, with mutually-exclusive events merged in single fields of the combinatorial result and events having the same weights merged according to a sub-total. The weights are applied to the combinatorial result and used to update a performance count. The performance count can then be used by power management software or hardware to make adjustments in operating parameters of the processor.

摘要： Disclosed are systems, methods, and computer program products for managing power states in processors of a data processing system. In one embodiment, the invention is directed to a data processing system having dynamically configurable power-performance states (“pstates”). The data processing system includes a processor configured to operate at multiple states of frequency and voltage. The data processing system also has a power manager module configured to monitor operation of the data processing system. The data processing system further includes a pstates table having a plurality of pstate definitions, wherein each pstate definition includes a voltage value, a frequency value, and at least one unique pointer that indicates a transition from a given pstate to a different pstate. The voltage value, frequency value, and unique pointer of a given pstate definition are configurable, during operation of the data processing system, by the power manager module in response to changes in the operating parameters of the data processing system.

摘要： Monitoring temperature excursions an assembly experiences over a life of the assembly is provided. A determination is made as to whether the assembly has been in service beyond a predetermined end of life objective. Responsive to the assembly failing to be in service beyond the predetermined end of life objective, a new temperature value associated with the assembly is read. A modifier value for a figure of merit (FOM) value is computed and added to a cumulative figure of merit value. The cumulative figure of merit value is compared to a cumulative stress figure of merit budget. Responsive to the cumulative figure of merit value exceeding the cumulative stress figure of merit budget, an identified stress management solution is implemented.

摘要： Processing system performance is improved while meeting power management constraints in a processing system by using activity factor headroom estimation. The method and system estimate the power consumption of the system from a model that relates measured activities at a present operating point to power consumption for any available operating point of one or more processors in the system. The method then chooses the operating point(s) with the highest performance among the available operating points that will still meet budgetary constraints or specific thresholds of power consumption. The budgetary constraints or specific thresholds may be dynamically adjusted, and the method will update the operating point(s) to maintain safe operation and maximize performance. The method provides the best performance for the executing workload while ensuring safe operation.
