Research output: Contribution to journalLetter


Task scheduling for multicore processors typically has aimed at higher throughput and lower power consumption, but the lifetime reliability may be harmed if negative bias temperature instability is not considered together. In this letter, a task scheduling which extends lifetime is proposed. Cores are given the chance to recover as long as performance is not degraded. The degradation simulator shows that the proposed scheduling improves the lifetime of a multicore processor by up to 36% over the existing task scheduling.
