Claim Text:
1. A method, in a data processing system, for determining a modeled age of a multi-core processor, the method comprising: for each core in a set of cores in the multi-core processor executing in the data processing system, determining, by age determination logic executing in the data processing system, a temperature via temperature monitoring logic, a voltage via voltage monitoring logic, and a frequency via frequency monitoring logic at regular intervals for a set of degradations and a set of voltage domains, thereby forming the modeled age of the multi-core processor, wherein the temperature, the voltage, and the frequency are measurements of run-time operational characteristics experienced by each core of the set of cores and wherein forming the modeled age of the multi-core processor comprises: determining, by the age determination logic, whether the modeled age of the multi-core processor is greater than an end-of-life value; and responsive to the modeled age of the multi-core processor being greater than end-of-life value, sending, by the age determination logic, an indication that the multi-core processor requires replacement.
