Abstract
A mechanism is provided for mitigating aging of a set of components in the data processing system. A modeled age of a component in the set of components is identified. A desired aging requirement for the component is identified and a determination is made as to whether the modeled age of the component is greater than the desired age of the component. Responsive to the modeled age of the component being greater than the desired age of the component, a policy is implemented to mitigate the aging of the component.
Claims25
A method, in a data processing system, for mitigating aging of a set of operating, components in the data processing system, the method comprising:
- identifying, by a processor in the data processing system, a modeled age of an operating component in the set of operating components;
- identifying, by the processor, a desired aging requirement for the operating component;
- determining, by the processor, whether the modeled age of the operating component is greater than the desired age of the operating component;
- and
- responsive to the modeled age of the operating component being greater than the desired age of the operating component, implementing, by the processor, a policy to mitigate the aging of the operating component via one or more run-time operating power management control parameters.
A computer program product comprising a computer readable storage device having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:
- identify a modeled age of an operating component in a set of operating components;
- identify a desired aging requirement for the operating component;
- determine whether the modeled age of the operating component is greater than the desired age of the operating component;
- and
- responsive to the modeled age of the operating component being greater than the desired age of the operating component, implement a policy to mitigate the aging of the operating component via one or more run-time operating power management control parameters.
An apparatus, comprising:
- a processor, and
- a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
- identify a modeled age of an operating component in a set of operating components;
- identify a desired aging requirement for the operating component;
- determine whether the modeled age of the operating component is greater than the desired age of the operating component;
- and
- responsive to the modeled age of the operating component being greater than the desired age of the operating component, implement a policy to mitigate the aging of the operating component via one or more run-time operating power management control parameters.
