Advancements in technology enable integration of a large number of cores on a single silicon die. At the same time, aggressive technology scaling has an ever-increasing adverse impact on the lifetime reliability of such large integrated circuits. In this work, we model the lifetime reliability of homogeneous manycore systems using a load-sharing nonrepairable k-out-of-n:G system with general failure distributions for embedded cores. In manycore systems, an embedded core can be in operational,
