Abstract
A mechanism is provided for determining a modeled age of a mufti-core processor. For each core in a set of cores in the multi-core processor, a determination is made of a temperature, a voltage, and a frequency at regular intervals for a set of degradations and a set of voltage domains, thereby forming the modeled age of the multi-core processor. A determination is made as to whether the modeled age of the multi-core processor is greater than an end-of-life value. Responsive to the modeled age of the multi-core processor being greater than an end-of-life value, an indication is sent that the multi-core processor requires replacement.
