Run-Time Adaptive Power-Aware Reliability Management for Manycores

Due to increasing process, voltage, and temperature (PVT) variability, reliability is becoming a growing worry. This article addresses this concern with a combination of software and hardware hardening modes while considering power, performance, and overhead constraints. Similar to other examples in this special issue, this work illustrates that complex management tasks that have to integrate multiple objectives, goals, and constraints require a comprehensive understanding of the system’s state.
