Due to rising integrations, low voltage operations, and environmental influences such as electromagnetic interference and radiation, transient faults may cause soft errors and corrupt the execution state. Such soft errors can be recovered by applying fault-tolerant techniques. Therefore, the execution time of a job of a sporadic/periodic task may differ, depending upon the occurrence of soft errors...
This invited paper summarizes two new steps towards dealing with dark silicon issues: Thermal Safe Power (TSP) and MatEx (both available as open-source tools at http://ces.itec.kit.edu/download). TSP is a novel thermal-aware power budgeting technique, which is namely an abstraction that provides safe power constraints as a function of the number of active cores. TSP conceptually and radically changes...
Reliability-aware power management (RAPM) schemes have been recently studied to save energy while preserving system reliability. The existing RAPM schemes, however, provision for worst-case execution scenarios and are rather conservative. In this paper, by exploiting the probabilistic execution time information of real-time tasks, we develop an optimistic RAPM scheme. Instead of scheduling a full...
