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.

Claims

1. 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.

2. The method of claim 1, wherein implementation of the policy causes the one or more run-time operating power management control parameters for the operating component to change thereby mitigating the aging of the operating component.

3. The method of claim 1, wherein implementation of the policy causes the one or more run-time operating power management control parameters for other operating components in the data processing system to change thereby mitigating the aging of the operating component.

4. The method of claim 1, further comprising:

responsive to the modeled age of the operating component being greater than the desired age of the operating component, determining, by the processor, whether a rate of aging of the operating component is greater than a desired rate of aging of the operating component; and

responsive to the rate of aging of the operating component being greater than the desired rate of aging of the operating component, implementing, by the processor, a policy to mitigate the aging of the operating component and the rate of aging of the operating component via the one or more run-time operating power management control parameters.

5. The method of claim 1, further comprising:

responsive to the modeled age of the operating component being less than or equal to the desired age of the operating component, determining, by the processor, whether a rate of aging of the operating component is greater than a desired rate of aging of the operating component; and

responsive to the rate of aging of the operating component being greater than the desired rate of aging of the operating component, implementing, by the processor, a policy to mitigate the rate of aging of the operating component via the one or more run-time operating power management control parameters.

6. The method of claim 1, further comprising:

waiting, by the processor, a predetermined time period to determine whether the implementation of the policy has reduced the aging of the operating component; and

responsive to the aging of the operating component being reduced, continuing, by the processor, to implement the policy until the aging of the operating component has been negated via the one or more run-time operating power management control parameters.

7. The method of claim 6, further comprising:

responsive to the aging of the operating component failing to be reduced, implementing, by the processor, a new policy to mitigate the aging of the operating component via the one or more run-time operating Dower management control parameters.

8. The method of claim 1, further comprising:

waiting, by the processor, a predetermined time period to determine whether the implementation of the policy has negated the aging of the operating component; and

responsive to the aging of the operating component being negated, implementing, by the processor, a new policy that meets the desired aging requirement for the operating component via the one or more run-time operating power management control parameters.

9. The method of claim 1, wherein implementation of the policy via the one or more run-time operating power management control parameters causes one or more of:

reducing, by the processor, an operating voltage to the operating component;

reducing, by the processor, the operating frequency of the operating component;

changing, by the processor, a temperature threshold at which cooling actions are triggered for the operating component;

allow, by the processor, a frequency or a voltage increase only if a net utility of doing so exceeds a predetermined utility;

power capping, by the processor, the operating component before power capping other components in the data processing system;

reducing, by the processor, workload assigned to the operating component by scheduling work to “

younger”

operating components, thereby spreading aging effects;

changing, by the processor, a computation model to utilize “

younger”

operating components, thereby spreading aging effects;

or

choosing, by the processor, a hierarchy for computation based on ages of the operating components.

10. 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:
