1. A method, in a data processing system, for determining a modeled age of a set of interconnect groups in a set of cores in a set of multi-core processors, the method comprising: for each interconnect group in the set of interconnect groups in the set of cores on the set of multi-core processors, determining a current modeled age of the interconnect group; determining whether at least one current modeled age of the interconnect group for the set of interconnect groups is greater than an end-of-life value; and responsive to at least one current modeled age of the interconnect group being greater than the end-of-life value, sending an indication to take corrective action with the at least one associated interconnect group.
