ABSTRACT:
A method of managing resources in a data processing configuration includes allocating system resources to an application to ensure a specified level of performance for the application. A system parameter is then modified to conserve power consumption upon detecting a condition resulting in a reduction of available system power. The original system resource allocation is then modified to maintain the specified level of performance following the modification of the system parameter. The system resources may include system CPU cycles and allocating system resources may include allocating a specified percentage of the CPU cycles to a high priority application. The reduction of available system power may be caused by an excessive ambient temperature or the failure of a power supply. Modifying the system parameter to conserve power consumption includes throttling the CPU speed and then dynamically increasing the percentage of CPU cycles allocated to the high priority application.
