Dynamic power and performance calibration of data processing systems

摘要

A method and computer program product for dynamic power and performance calibration of a data processing system comprises executing a program 804 responsive to detecting an event 802, the program configured to generate data 806 indicative of the systemâ s power-performance characteristics or metrics which are measured under varying conditions of operation. The set of data is used to determine a performance or power limit on an operation of the system under present operation conditions, and a parameter of the system is calibrated 810 to operate the system within the performance limit. The program may cause the system to exhibit a behaviour approximating behaviour evident from initial power-performance data. A power-performance model may be created 808 using the set of data. Calibrating the system may include adjusting a planned workload on the system. The event may be a power-on self test event, a workload configuration event or a system configuration event.
