Lifetime reliability is an emerging concern in multiprocessor systems as escalating power density and hence temperature variation continues to accelerate wear-out leading to a growing prominence of device defects. In this paper, the authors propose a platform-based design methodology that involves performance aware task mapping on a multiprocessor system to jointly minimize energy consumption and temperature related wear-out. Fundamental to this methodology is a simplified temperature model that incorporates not only the transient and steady-state behavior but also its dependency on the temperature of the surrounding cores.
