Technology scaling and reliability challenges in the multicore era

This work provides elements to highlight the reliability challenges related to the technology scaling in the multicore era. Through main milestones including device reliability scaling models, single-core scaling model and multicore chip organization and scaling models, the reliability impact on the speedup potential of multiprocessors for a set of parallel real workloads is assessed. The main conclusion of this study is to highlight the fact that the “free lunch” for overdrive conditions is soon to be over.
