Increased Reliability of Many-Core Platforms through Thermal Feedback Control
Matthias Becker, Kristian Sandström, Moris Behnam, Thomas Nolte · 2014
In this paper we present a low overhead thermal management approach to increase reliability of many-core embedded real-time systems. Each core is controlled by a feedback controller. We adapt the utilization of the core in order to decrease the dynamic power consumption and thus the corresponding heat development. Sophisticated control mechanisms allow us to migrate the load in advance, before reaching critical temperature values and thus we can migrate in a safe way with a guarantee to meet all deadlines.
